AMD Ryzen 7 7800X3D CPU Review & Benchmarks

the biggest thing that the 7800x3d does is make the 700x3d look like trash which actually should be the opening line for this video so we'll just today we're reviewing amd's new ryzen 7 7800x 3D CPU this is an 8 core 16 thread CPU it's 450 and it comes with the amd's 3db cash but it's a single CCD that's the core part in all of the specs because oh it's the core part that wasn't intentional it's the main part of importance though for this because the 7950x3d and the 7900 x3d both had a core parking conundrum where you effectively turn off half the cores in order to play games and it works okay but this doesn't need to do that so the closest competition here is going to be the 13700k the 5800x3d from AMD previously that's still a fierce fighter right now and we'll be looking at both of those along with the other over a dozen CPUs on our charts and we're excited for this review specifically because we're adding a lot of depth in this so we always collect frame time data that's how we build our frame rate chart but this time we're going to present a couple more frame time charts to give you a more empirical look at the gaming experience frame to frame between the 7800x3d and the 13700k and the boxes on the floor didn't have CPUs in them just so we're clear on that but let's get started this video is brought to you by us and our brand new projects and solder mat on store.gamersaccess.net we just launched this mat and the reception has been amazing our new mat is made of an extremely high heat resistant silicone and is perfect for everything from hobbyist projects like Gundam building up to soldering components and it can take direct exposure to soldering irons flux tinting the materials heat guns all without issue our mat has carefully placed a larger sized screw sorters and small part organizers with the left side outfitted with larger part trays for phone screens and heat sinks screwdriver holders dot the mat in different places and depths making it easy to organize paint brushes drivers tweezers and flux and they're accompanied with spool organizers to make it simple to keep track of everything in one place our brand new mats are in stock and shipping now on store.amersexus.net and support our in-depth reviews like this one directly grab one today all right so for the data today as stated we're really excited for it because we've added more we have 1440p charts more than usual we typically don't include them but we collect the numbers and then we also have in addition to the frame time data uh individually broken out for the 3700k comparison we've brought in some really good Showcases of terrible data that is easy to run into with the CPU if you're using a contaminated OS we'll show that and plenty more like power efficiency gaming and production so here's the quick overview for the parts the 7550x3d and the 7900x3d have already launched they came out about a month before this we reviewed both of them separately and we explained the CCD issue and the core parking issue in detail in the 7950x3d review so we'll leave that there for you if you want to learn about it if you don't know the 7000 X 3D CPUs stack the V cash on only one CCD so AMD composition for ryzen CPU 7000 series right now is going to be a maximum of three chip Lids where you have one is the i o die doesn't count just ignore it one is the primary CCD one is the secondary where secondary isn't always there and primary is the one that gets the V cash on the previous x3d CPUs you would have to park half of the cores or not use them in gaming because otherwise you end up having to cross the interconnect or the infinity fabric to go from the secondary CCD to the primary CCD if there is a cash hit on that V cash that's stacked the added latency was worse for performance than just restraining all gaming traffic to a single CCD and that's where the 7800x 3D comes in it resolves the issue by moving to a simpler layout and the reason for that is because the 700x3d when you park the cores so you're not using that second CCD and potentially hindering latency heads you're cutting it down to a six core CPU effectively for gaming whereas this is eight and it's still single CCD so don't be surprised when the 78x3 app performance 79 only in scenarios where the frequency is more beneficial will it really uh be more of a toss-up or allow the 790 claw backs on that loss because AMD has segmented the 7800x3d down in frequency enough so that it doesn't compete too hard with amd's own high-end CPUs as for those specs the 78x3d drops the frequency hard to just 5 gigahertz has the up to Max Boost number that's a big fall from the 7950x3d is a 5.7 gigahertz and we suspect that's to create the segmentation now as with the 750 x3d it's incredibly easy to screw up the install or testing for the 7800x3d we installed an entirely new Os from this because trying to transition between the x3d CPUs and this generation causes problems it contaminates the OS and here's an example of why that happened as a reminder this chart is for the 7950x3d and half of the cores are parked they're doing nothing and that's during gaming that's a good thing because it's performance tanks from Cross CCD V cash hits otherwise we talked about this in the last one and here's the 7800x 3D version of that chart this is bad data though this chart is on the same OS we used for the 7950x3d but with a full manual wipe of the chipset drivers and with installation of new drivers from scratch even with all of that careful removal and swapping of the chipset drivers the OS remained contaminated by Andy's core parking add-ons that are meant for the higher end x3d CPUs and so half of the cores on the 7800 X 3D were parked as well that's bad because of the single CCD stuff we talked about earlier this would ruin results if the tester doesn't notice it we installed the new OS this resolves the problem completely and means that there are no more driver Gremlins left behind so we're all good for our data but we wanted to show you what it'll look like if you end up upgrading or something like that in the future let's look at frequency frequency is important to understand on this part because AMD is tweaking the frequency so far down on the 7800x3d it's possible that it actually underperforms versus a 7700x in scenarios where the V cash isn't helpful this plot shows a sustained all core workload the 7800 xvd ran at about 48 50 megahertz when averaging all cores this is significantly lower than we're used to seeing on Zen 4 parts and explain some of the upcoming disparities adding the 7700x to the Chart we see an average of 5180 to 5200 megahertz all core it's a substantial uplift and that'll benefit it heavily in anything that favors frequency to cash that's not just single threat either this is an all thread load now we're getting into Power testing which is one of the most interesting aspects for the xbd CPUs because they're very efficient so for power testing we have two primary charts one is power efficiency one is power consumption and all core workload for power consumption we look at the EPS 12 volt rail current draw and we use that to get an accurate number for the wattage that the CPU is using for efficiency what we're looking at is the amount of energy required to complete a known amount of work so let's look at the first chart here we go then all Core 100 power consumption has the 7800x3d at 86 Watts when measured directly at the EPS 12 volt cables it's about the same power consumption as the efficiency tuned non-x R5 7600 and R9 7900 which is great positioning for perspective the 7700x pulled 148 watts in the same test so the 7800x3d has improved in at least this aspect compared to the i7 13700k is 280 Watts under the same full load the 7800 X 3D maintains a significant Advantage it's a 200 watt reduction it's a lot this doesn't factor in low load scenarios or mixed load scenarios but for all core production style workloads like blender it's significantly lower power as for whether it's more efficient for at least this test that's our next chart here's the efficiency chart the 7800 x3d is 18 watt hour result has it more efficient than the 7700x which needed 29 Watt hours to complete the same work that's a reduction of nearly 40 percent in what our cost or energy consumption compared to the 13700k at 38 Watt hours the 7800x3d benefits from a 52 reduction in Watt hours and pose significantly advantaged efficiency in an all-core full load scenario being the most efficient doesn't technically mean that it completes first or anything like that it just means that it completes a known amount of work with lower overall energy consumption for that same fixed work that's being completed now we're getting to the frame time charts we're experimenting with publishing more of these in our reviews because we it's the most empirical purest look at the frame to Frame data that you can get but the problem is frame time charts are not clean you can't get a lot of bars on them you can't get a lot of comparisons on them once your past two devices it gets kind of hard to interpret and read them and the lines obscure each other so for this we have just two CPUs the 13 7 and the 78 x3d and then we have everything else in the rate charts as usual but let us know what you think about this because we are adding the extra data if people don't care that's fine you can always get it in the average FPS charts but this gives you a little bit more info so uh first of all some quick education here frame times are simply put the metric that is used to derive the frame rate you turn the time into a rate it's pretty simple math but the reason frame times are interesting is because uh frame rates and averages even one percent lows and 0.1 percent lows which are averages those start to blur over any massive excursions or minor problems in if they are not sufficient to change the average itself in a way that triggers the technician to check that data more closely now normally that's fine because for us when we see numbers that look out of place we check more closely we give you these charts but now we want to present them uh more frequently so what you're going to be looking at is the y-axis is milliseconds required to render or present the frame to the screen and excursions greater than eight milliseconds tend to become noticeable but primarily if they are frequent in occurrence whereas excursions that are significant let's say 150 milliseconds or especially 500 milliseconds half a second one of those is noticeable as like a hitch or a stutter so that's what you're gonna be looking at and these will be just head to head let's get started here's the Cs go frame time plot at 1080p the 13700k plots between two to four milliseconds on average which is ridiculous with two spikes to around 10 milliseconds and a few other minor spikes none of these are frequent or large enough to be noticeable you need more frequent eight millisecond plus deviations or much larger excursions the frames of frame experience is consistent here the same goes when we add the 7800x3d to the plot this runs almost exactly the same intervals although with marginally wider ranges top to bottom against the average the spikes are similar in count and the difference between the Peaks is within reasonable run to run variation on the two CPUs so they're about the same with cyberpunk the 13700k fluctuated below 8 milliseconds on average the load is easier for the CPU earlier in the test with difficulty ramping towards the end only two massive spikes appear and one breaks the chart bounds the worst of these two lands at 42 milliseconds which is enough of a swing to be briefly noticeable as a stutter maybe depends on what you're doing in the game when plotting the 7800x3d we noticed frequent excursions from the mean the frame times regularly jumps about four milliseconds over the prior frame but a four millisecond Delta itself isn't particularly bad and this isn't as bad as micro stutter but the consistency with which it happens indicates an issue and not just some one-off spike despite this the CPU remains more than playable the x3d spikes at the same spot as the 13700k did at the end with a timing lining up on further inspection with a scene change in the game the x3d spikes to 60 milliseconds here versus 42 on the other but it happens on both so this effectively nullifies it in a comparison because it's just it's a game loading scene change in Far Cry 6 the overall frame to frame consistency is excellent on both CPUs the 13700k is slower and frame rate and hits a snag of several spikes around frame 700 the x3d is technically faster in frame rate but has its own occasional spikes on frame time the spikes experienced on both of these CPUs are a normal part of gaming they aren't anomalous unplayable or anything we'd characterize as weird it's just software and both are fine despite their unique behaviors the x3d is is advantaged here over the 13700k that's something we know about Far Cry with v cash so now we're moving to the rate comparison so average FPS one percent and 0.1 percent loads shadow of the Tomb Raiders up first this shows greater response for x3d CPUs the 7800 x3d positions itself in second just behind the freshly retested 7950x3d at 386 FPS average the 7800x3d leads the still good 5800x3d by 16 percent the 3900k by a mass of 27 percent while being about 100 cheaper and the 13700k by 36 percent although the 7800 xpd cost five to fourteen percent more than the 13700k depending on pricing at the time this goes up that's far better scaling than the one percent FPS for one percent more money scale that we seem to be stuck on for the GPU market so at least in CPU land it's still somewhat sane the x3d CPUs have established their own cluster at the top of this chart demonstrating that as we have said before it works great when games can make use of it we run 1440p for this one as well you can see that the GPU has capped the maximum performance for all CPUs expectedly but the x3d chip still punch above everything else on the charge testing Counter-Strike GO at 1080p the R7 7800 x3d landed at 407 FPS average with lows paced proportionally at 291 and 220 FPS this is slightly better than the 7550x3d that we just retested and the lows are significantly better than the preferred frequency test that we ran on the 7950x3d previously the direct 13700k competitor manages to outperform amd's 7800 X 3D and average FPS marginally 1.6 percent here with one percent lows the same and 0.1 percent lows worthy of further inspection but we did that our frame time chart earlier more importantly the 7700x outperforms the 7800x3d here that was true of the 7950x outperforming the 7950x3d as well the extra for V cash just isn't helping the 7800x3 in this title that's fine they don't always use every feature and in this case CS go just cares more about the frequency and kind of the cores than it does that extra cash CS go at 1440p is functionally the same it's CPU bound so the results don't change we'll Breeze past this chart Final Fantasy 14 end Walker is next tested with the built-in Benchmark to avoid the huge variable presented by connecting to the network the 7800xpd ran at 252 FPS average with a low space as we'd expect for AMD CPUs at 137 and 106 FPS average for one percent and 0.1 percent lows the 13600k maintains better lows and has a tied average to the 7800 X 3D making the 7800xpd worse value than Intel's 300 I5 CPU this 7950x3d and 7900 xvd offer no meaningful change from the new 7800 X 3D maybe that's part of why AMD delayed the launch on this one 1440p is largely the same we're C CPU bound so that's good to confirm and play it at 1440p with a 4090 it would still benefit from the same CPUs as the 1080p performance we plotted Far Cry 6 is another game that performs particularly well with 3D V cash the 7800x3d is our new chart topper at 224 FPS average leading the 7950xpd by 12 percent and with lows about the same the lead over the 3900k is similar with a 20 lead over the directly competing i7 at 13700k that's a good show in from amd's newest part here the 13600k remains good overall value though at a relatively high end tying the 5800x video in performance but the 7800x 3D takes away all the high-end dominance from all the other parts performance at 1440p is about the same with some loss off the very top end of the score the 7800 XD maintains its leading position here overall in cyberpunk 2077 the 7800 xpd ran at 260 FPS average with lows at 118 and 79. that that has it about equal to the 7900x3d which is not good for the 7900 x3d that is but it's behind the 13700k and frame time consistency the averages are the same but as we saw in our earlier frame time plot the 13700k maintains an advantage in this specific title the 750 XD pushes slightly higher with its frequency Advantage F1 2022 is next tested at 1080p High the 7800x3d ran at 508 FPS average here allowing the 7950 xpd a lead of one percent it's massive definitely worth hundreds of dollars the 7800 actually that was sarcasm before somebody goes and buys it the 7800 X 3D leads the 7900x3d once again thanks to its core Advantage when gaming compared to the 3900k the 7800 x3d holds an 11 lead in average FPS with lows also improved the 13700k gives up a 17 lead to the 7800x3d which again leads in lows as seen in the frame time plots this is another scenario where the x3d CPUs actually seem to be doing something the game can leverage it but it's a scenario that makes the 7900x3d look like a total waste in comparison to the new 78 x3d kind of makes sense why AMD delayed this one now in Total War Warhammer 3 the 7800 XD pushed to 311 FPS average and functionally tied the 13 700k competition that's not great considering the 3700k is cheaper but it could be enough to hold the line when considering the full picture of other games we'll talk about that at the end the 7800 X 3D app match is the 7900xpd once again further driving the nail into that coffin for gaming for the 79 xrd The 13600k Remains the fiercest fighter against all these expensive CPUs and still offers some of the best overall high-end value so it would be worth considering giving up 10 FPS for big savings that can be diverted to gpus or memory instead now we're getting into production testing this is workstation applications content creation applications things like that this is where the value will start to degrade because historically the additional cash does not benefit these CPUs in the applications we test for production as much as say more cores or frequency would blender Cycles rendering is first this uses a tile-based renderer where one tile is spawned For Thread even with all 16 threads running the 7800 x3d is heavily disadvantaged here the 7700x outperforms it benefiting from the higher frequency more than the cash the 13600k also embarrasses the 7800 xpd for the price using its 6p cores and the e-cores total in 12 threads with hyper threading to land a 10.7 minute render time that's a reduction of 16 percent against the 7800 X 3D it's not a good start for AMD on production value it can do it but you really need to be buying it as a gaming first CPU that can handle this type of work as a secondary when compiling the chromium code base the 7800 xod required 67 minutes to complete the compile getting beaten once again by by the 64-minute results of the 7700x the 13600k has a 19 lead driving the dagger in for amd's x3d in this type of workload in file compression benchmarking ranked in millions of instructions per second the 7800x3d once again falls behind it completes 118 000 mips here allowing the 7700x lead at technically 122 000 mips and the 13600k elite at 132 000 mips the comparably priced 13 700k meanwhile is 35 ahead with a 159 000 MIP score decompression has the 7800x3d at 135 000 mips once again positioning the 7700x ahead of it in this one it at least ties the 13600k and gets proportionally closer to the 13700k but the value is still bad Adobe Premiere is tested in aggregate with a Puget Suite analyzing scrubbing playback render Time Warp stabilization and other effects the 7800x3de scored 1000 57 points putting it behind the 5900x 7700x 13 600k and 13700k it's only outperforming the R5 7600x and the 5800x3d from the recent Generations the Photoshop is tested the same way just with different filters and features the 7800 x3d ranks relatively high on this charge but it's still behind the 7700x and 13700k it manages to outperform at least the 13600k though now we're moving into thermals first of all thermals can't be compared cross brand in any meaningful way so Intel and AMD the temperature means different things because for example Intel has a 70 degree threshold for TVB to activate AMD has pb2 where scaling is affected all the way up the line and it boosts the TJ Maxx now so you can't compare them cross brand and really cross architecture you shouldn't be either because sensors are different spots they mean different things and they report differently and it just behaves differently but as a reminder temperature even when we do compare them within the same architecture which we're going to do today isn't some 3D Mark score so it's not like this this one runs at 70c that's not how it works it doesn't mean anything because the cooler the ambient temperature the cooler fan speed uh the case all of these things the the load is it AVX or not all of it impacts the temperature that comes out the other end all that matters for our testing here is that is a pure a b comparison and we are doing it for educational purposes to look at how the 78x3d behaves versus the 7700x it's that simple the 7800x3d with our liquid freezer 2 360 attached ran at 75 degrees Celsius this is relatively low for Zen four because as another reminder Zen 4 typically boosts the clocks until it hits TJ Maxx in this instance the 7800x3d has both a lower TJ Maxx to protect the sensitive V cash and also a lower frequency ceiling to protect the 750 x3d from getting cannibalized through hard 75 is relatively low for this generation and illustrates that we're hitting other caps prior to the thermal limiter which although lower is still higher than 175. the 7700x however did boost the TJ Maxx that's how it's designed with the same cooler it pulled more power and pushed frequency higher as you saw earlier until it hit about 92 degrees Celsius average all core moving on to the main points then so the 7800x30 is extremely efficient this follows on the same path AMD was setting with its other x3d CPUs not necessarily with the initial 7000 launch but they got there with eco mode so it is very efficient in at least all core workloads that's a good thing for gaming we did see uplift and it was meaningful when the 3db cache works and it doesn't work in every game we've talked about this a lot already not going to cover when and why it works but when it works it is actually good and it does make the CPU strongly worth considering we'll go over more of that in a second this is a total waste in production first use cases so if you are not gaming as a primary use for your computer you should buy something else it's really as simple as a 7950x or 3900k 700k 13th gen seriously worth considering for something like a desktop class computer you use for Adobe software compiling compression decompression maybe but amd's more competitive there especially decompression either way this CPU does not make sense for those use cases because you're spending the money on something that those applications can't use you could spend that same money on a more powerful CPU for those applications but for gaming it's worth talking about and then the last major point before we get to the details is this as we said earlier makes the 7900x3d look absolutely terrible as any kind of value for gaming and it's it's for easy reasons we already explained them so this basically pretend the 79x3d doesn't exist this invalidates it and we had a feeling it was going that direction when we viewed the southern x3d a month or whatever ago it was it's been a long time now uh that that those CPUs have been out and this one was in the wings so going over the details uh the reason it looks terrible is because it's getting beaten in scenarios where the eight cores on this are better than the effect of six cores on the 79 when you're parking the cores uh all you're giving up there is between the two CPUs is maybe a workstation Advantage definitely and the 79x3d but for other reasons already mentioned it's irrelevant secondly uh the 7800x 3D for gaming occasionally the 7700x Beats it but that's when frequency matters more than the additional cache we showed a chart earlier demonstrating it but the frequency is higher on the 7700x in our testing for an awkward workload and that benefits it in games where that's what they care about really rapidly recapping the charts then the biggest competitors are the 13 7 and the 13-6 in CS go they make more sense but that class for performance 13700k at the same price roughly or cheaper is better assuming no other options exist than the 7800x3d in cyberpunk the 13700k and 7800 xvd were tied with the advantage to the 13700k for lows in F1 there was a massive performance boost for x3d as we've seen before and a big gain versus the 13700k Far Cry 6 78x3d was a clear leader Final Fantasy 14 the 13 Seminary kit was a clear leader so they're going back and forth here in Shadow of the Tomb Raider the 78x3d was a clear leader it's not even closed and in Total War Warhammer it was about tied so where that leaves us then is I suppose analyzing how large is the gap when there is a gap between the CPU and to whom does the favor go for the most part when there's a gap it largely benefits the 7800x3d however when the 7800 xvd is not leading the 13700k is lead other than Final Fantasy it's maybe less impressive but overall they do go back and forth a bit the 13700k to us uh maybe makes more sense as an all-around CPU being a little bit cheaper and uh also having advantages in production workloads if you are only gaming then the 7800 x3d suddenly becomes much more worth considering but unfortunately there's no easy answer for unless you play one of the games that a Reviewer is testing how much does it help you personally because it is very game to game it's not as clear a cut the 7800 activity is much better value than the 700x3 the 79 now looks like a complete another joke the 7950 xvd has more or less been entirely invalidated and more so maybe than previously previously had that sort of but it's technically the best that it could hold on to but now it's not even really uh it's not enough so from our perspective you're either looking at a 78x3d from AMD for the top end gaming CPU just ignore the others they're not worth the money and sometimes they're worse or the 13700k for the same price those are the two to narrow it down a lot and the 13 6 remains amazing value if you want to get basically top end CPU performance for 300 to save money for your GPU or Ram or something so that's it for this one thanks for watching as always let us know what you thought of the additional depth on the framed lines if you want to suspend review Air time on that in the future we can add more of them or do more interesting analysis If people really like it uh something we did a long time ago but we moved away from it because just can't fit as much stuff on the charts and uh requires every time a little bit more audience education because anytime you get new people in who haven't seen them before we need to explain it which is totally cool and I love doing it but it does mean you get an extra 20 second explainer every time okay that's it for this one thanks for watching as always subscribe for more go to score.com net to grab one of our brand new

There's probably that 1 person who bought a 7900X3D & 7900XT card as the "value" option this current gen.

[u/JuanElMinero]

TL;DW:

Gaming performance is mostly in the ballpark of the 7950X3D, like previous simulations from 7950X3D reviews already showed.

Notable deviations:

• Far Cry 6: +10% avg fps vs 7950X3D

• Cyberpunk: -25% on 1%lows and -10% on 0.1%lows vs. 7950X

• FFXIV: +30% on 0.1% lows vs. 7950X

• TW Warhammer 3: +40% on 0.1%lows vs. 7950X

It seems those 1% lows in Cyberpunk generally improve above 8 cores for non 3D parts, on the other hand the 7600X beats the 7700X here. Someone please explain if you know what's going on.

Wooo! Frametimes! Been wanting heavier focus on this for a while!

Now, if they would consider breaking them out into their own dedicated videos similar to how DF has done them in the past, I’d be ecstatic

I swear people don’t pay enough attention to these metrics; which is wild to me since it’s the ones that determine if the game is a microstutter mess or actually smooth

[u/Khaare]

Steve mentioned the difference in frequency between the 7950X3D and the 7800X3D. As I learned in the 7950X3D reviews, the CCD with V-Cache on the 7950X3D is actually limited to 5.2GHz, it is only the non-V-Cache CCD that's capable of reaching 5.7GHz, and therefore the difference in frequency in workloads that prioritize the V-Cache CCD isn't that big.

[u/bert_lifts]

Really wish they would test these 3d cache chips with MMOs and Sim games. They really seem to thrive on those types.

[u/knz0]

It's a killer CPU, pair it with a cheap (by AM5 standards) mobo, 5600 or 6000 DDR5 which are reasonably priced these days and a decent 120 or 140mm air cooler, and you have top of the charts performance that'll last you for years

[u/bizude]

I kinda wish I had waited for the 7800X3D instead of going with the 7700X :D

[u/Hustler-1]

I play a very niche set of games. Kerbal Space Program (1) being my main. But there will be no benchmarks for such a game. However could it be said that the X3D CPUs are dominant in single core processes? Like what many older games are.

If not what exactly is it with the vcache that some games really take advantage of? Trying to gauge whether or not it would be good in the games I play without actually benchmarking it. Because I want to see how much of an upgrade it is without having to buy anything.

I can't imagine anyone buying a 7900X3D if they have any understanding of how these CPUs operate and their limitations. It's difficult to imagine a user who prefers the worse gaming performance vs the 7800X3d, but needs extra cores for productivity, and isn't willing to spend an extra $100 for the 7950X3D, which improves both gaming and productivity.

This review of the 7800X3D really drives it home. The 7900X3D really just seems like a 'gotcha' CPU.
