AMD Ryzen 9 7950X3D Benchmark + 7800X3D Simulated Results

foreign [Music] box today we're taking a look at the New Horizon 9 7950x 3D the first of the 3D vcash enabled zenfall Parts well I suppose that's not entirely true because there's also meant to be the 7900x 3D but AMD hasn't provided a sample for that part probably because I don't think it's going to make a whole lot of sense there will be just six cores with the 3D V cache so I think either this part of the upcoming a 7800 X 3D would be the better buyers today's video is sponsored by LG and their brand new 27 inch Ultra gear OLED gaming monitor the 27 gr 95qe this display is the perfect choice for high refresh rate HDR gaming has a blazing vast 240Hz refresh which combined with Elite response times gives you super clear motion among the best we've ever tested plus you get a stunning HDR experience thanks to all leads per pixel local dimming and deep zero blacks giving you that Punchy vibrant dazzling image quality we expect from a through HDR product which this is I recommend this monitor it performed well in our review over on monitors unboxed so to learn more and upgrade yourself to an ultra gear OLED check the links in the description below now there's also the ryzen 7 7800x 3D which like the 7700x is an eight core 16 thread processor and truth be told it's the Zen 4 3D V cache part that we're most excited for so in typical AMD fashion they have delayed the release of their most interesting part for another five weeks and why you might ask don't know and there's really no technical reason for it so it would seem as though amd's doing this simply to push buyers towards spending more on the 7950x 3D or 7900x3d now look the 7150x 3D is arguably the better deal at 700 as it costs 44 dollars per call whereas the 7800 X 3D at 450 that's set to cost 56 dollars per core and almost 30 increase but then only half of the 750x 3D cores actually feature 3D V cache technology so the comparison isn't exactly that straightforward so in total the 7950x 3D packs 128mb bytes of L3 cache but as this is a dual CCD product not all of the cores can access all of the L3 the cause in the primary CCD for example get the standard 32 megabytes plus the Stacked 64 megabytes of 3D V cash for a total of 96 megabytes whereas the cores in the second CCD only get the standard 32 megabytes this means gaming performance has the potential to be significantly improved when the processing is handled by the primary CCD essentially making the 7950x 380 an 8 core processor the problem or rather challenge is that it's imperative that the 3D V cache enabled cores handle gaming tasks with the second CCD being treated more as if they were equals of an Intel processor an amd's dual CCD CPUs are really quite tricky when it comes to gaming and we often see a performance decline due to the larger latency penalty seen when communicating across the infinity fabric this makes the 59x3d more of a hybrid gaming CPU in my opinion it's unlikely to be amd's best gaming CPU nor will it be their best productivity CPU the best gaming CPU is almost certainly going to be the 7800x3d while the best productivity CPU will be the standard 7950x as it's able to clock higher now the 7800x3d that won't suffer the same latency penalty when communicating amongst cores and you don't have to worry about how the operating system or game utilizes or sees the CPU meanwhile the 7950x will be faster for productivity work again just for the simple fact that the cores can clock higher so the 7950x3d is really for those who want to work and play and are looking for sort of the best possible performance for both tasks out of a single chip now to ensure that the processor works correctly AMD recommends using the latest version of either Windows 10 or Windows 11 a 3D V cache specific bias for your am5 motherboard so a bias update will be required for Optimal Performance day mode must be enabled the Xbox game bar app needs to be up to date and the latest chipset driver must be installed out of Interest I decided to test the 7950x3d on my existing am5 test system with no updates and I can confirm performance was poor basically slower than the 7950x in all of the games I tested so you absolutely need the correct bars and chipset driver at a minimum now all of the testing was conducted on our new am5 test system built inside the Corsair 4000d airflow case using the IQ h150i Elite LCD XT liquid cooler RM 1200X shift power supply and 4 terabyte mp600 Pro XT SSD so a big thank you to Corsair for helping out with that Hardware the 4000d airflow is a fantastic case ventilation is excellent as is the cable management and with the IQ h150i Elite LCD XT red shoved in the front the 7950x3d ran really well I've got to say as good as the elite LCD XT looks though my favorite bitter kit here is the new RM 1200X shift power supply why we haven't seen a design like this until now is a bit beyond me it's so much easier to work with and just much easier to get a really nice neat finish great Cable Management I genuinely love this power supply also worth noting is the new MSI mag x670e Tomahawk motherboard which MSI sent over just in time for the 7950x 3D release now although we did install this board in the 4000d airflow case for some testing and featured it in the b-roll we still stuck with the aorus master for our benchmarks as that's what we've used for all the other CPUs and AMD also provided a bios for the 750x3d on the aorus master still it is good to see MSI releasing another x670 board and the tomahawk marks their fifth release msi's pricing the tomahawk at 330 us to compete with the Asus tough x670e plus Wi-Fi which makes sense as they are quite similarly equipped though the tomahawk does pack what should be a more robust 14 power stage v-core using 80 amp rated components now for the testing I normally include a lot more application benchmarks than what you're about to see and the reason why I've cut down this section of the review is because when it comes to productivity the 7950x 3D is basically just a slightly slower version of the 7950x as the primary CCD can't clock quite as high due to the 3D V cache so the focus is going to be on gaming performance as this is where the x3d part should shine as for the rest of the test notes all of the test systems have been configured with a GeForce RTX 4090 Windows 11 and resizable bar has been enabled okay let's get into the data first here's a look at the operating behavior of the 7950x3d during the cinebench R23 all-core workload the 3D vcache enabled ccd1 typically clocks between 4750 and 4 800 megahertz where a ccd2 with the standard 32 megabytes of L3 cache that clocked its cause at 4 900 megahertz the standard 7950x for example clocks the ccd1 cores at 5.1 gigahertz and it's ccd2 at 4.9 gigahertz so around a four percent clock speed Advantage for the original model also worth noting is that along with the lower TDP when compared to the standard 7950x 120 watts versus 170 Watts the 3D V cache part also sees the TJ Max load from 95 degrees to 85 degrees so I guess that's good news for those of you who didn't believe that 95 degrees was a safe operating temperature for Zen 4 that it was done by Design hopefully 85 degrees is more acceptable there because this will be the operating temperature with pretty much any AIO or air cooler and the results you're seeing here are with the Corsair IQ h150i Elite LCD XT installed now with just ccd1 enabled so the 3D vcache enabled CCD The Clocks Were slightly higher at 4 830 megahertz so around a percent increase compared to what we saw with both ccds enabled then if we disable ccd1 and just have the second CCD enabled the core is clocked at 5220 megahertz so that's a seven percent boost when compared to what we saw with both C Series enabled so if you could remove the thermal and power limits of the 7950x3d you would see a bit of a performance uplift but due to time this isn't something we've been able to explore for this review and this right here is why I'm not going to waste your time with a load of productivity benchmarks if you want to know how the 7950x 3D performs for compression decompression video production and code compilation work please just watch our 7950x video and deduct about five percent from the result and this is exactly what we're seeing in cinebench R23 where the 3D V cache model is five percent slower than the original making it 12 slower than the 1300 KS though power usage of the core I9 to achieve this result is pretty insane and we'll look at that in a moment single core performance should be much the same especially if the application is instructed to prioritize the second CCD without the 3D V caches those cores do clock higher here the 7950x3d was just one and a half percent slow on the 7950x though that did make it substantially slower than 1200 KS as it was 13 slower so for lightly threaded applications such as Adobe Photoshop 2022 the 7950x3d can be quite a bit slower than the 13900 KS here for example it is 11 slower and then three percent slower than the standard 7950x now while those ecors of the 1300k are great for accelerating cinebench scores they're not always that efficient and here we find that to be the case in blender where the 7950x3d is eight percent faster than the 1300 KS and again just three percent slower than the standards 7950x the issue with the 1300k when it comes to productivity is power consumption and while you can enforce power limits that will reduce performance extending the 7950x's lead further so whereas the 1300 K slash KS push total system consumption adjust Shire 500 watts the 7950x 3D ran comfortably under 300 watts using less power than even the 13600k which is super impressive also despite the addition of the 64 megabyte 3D V cache total system usage was reduced by 30 when compared to the standard 7950x and again that is due to the 120 watt TDP versus the 170 watt TDP of the original okay so time for the gaming benchmarks and we'll start with factorio which was an impressive showing for the 5800x 3D and is still to this day the 7950x 3D on the other hand not so much as the 3D V cash enabled chip was really no faster than the standard 7950x it appears as though this workload is running on the wrong CCD and is therefore not taking advantage of the 3D V cache and to prove this Theory I just went ahead and disabled the second CCD and the BIOS and re-run the test labeling the result as 7800x 3D simulated because I think that's essentially what this configuration is and this does look a lot better with the second CCD disabled we're seeing an almost 80 percent increase in performance for the 7950x 3D AKA 7800x 3D with a score of 433 points the upcoming 7800 X 3D should be around 25 faster than the 5800 X 3D and 60 faster than the 13 100K giving AMD an easy winning simulation games such as factorio now for testing CPU performance in Hogwarts we're testing in the hogsmeade section of the game here the 7950x 3D produced the best result yet with an average frame rate of 84 FPS though this made it just five percent faster than the 1300 KS using 7200 memory but it was also a 14 uplift over the standard 7950x then with the second CC disabled performance did decline in this example suggesting that the 7800 X 3D will be comparable to the 13900k in this title now Spider-Man remastered appears to hit a performance wall around 140 FPS the 7950x3d was good for 136 FPS which allowed it to match the 1300k ks with the Intel CPUs using ddr560 400 memory this also meant the 7950x ready was 10 faster than the 7950x so not a massive uplift there but a nice performance boost all the same however if we disable the second CCD for a 7800 X 3D simulated result the average frame rate improved by three percent but the one percent lows by a much more substantial seven percent and this means the 7800 X 3D could be up to 20 faster than the 7700x in this game now ACC was a big hit for the 5800x 3D blowing away all other CPUs that were available at the time however Intel has largely caught up with their 13th gen series and now the 5800x30 is just three percent faster than the 13900 KS using ddr5 7200 the 7950x3d on the other hand is faster than the 5800 X 3D but only by a mere one and a half percent and disabling the second CCD didn't boost performance here so disappointingly these new zen4 3D V cash Parts really aren't that much faster at least in this example next up we have shout out the Tomb Raider and here the 7950x3d was five percent faster than the 1300 KS using ddr5 7200 so good result there for AMD the 3D V cache is also providing around a 20 boost over the standard 7950x now disabling the second CCD did boost performance and show of the Tomb Raider increasing the average frame rate by a further five percent however it was the massive 18 increase in one percent lows that stood out the most here the original Zen 4 Parts already offered strong one percent lows in this title and with that second CC disabled that pattern continues now Rainbow Six extraction like factorio just sucks with the 7950x 3D and in fact performance here is broken I did notify AMD of this but they didn't get back to me with a solution in time for this review so the results remain as they are and when I say sucks I mean at least when compared to the 7950x the end result is still highly playable performance and very satisfactory one percent lows of 287 FPS but the average frame rate was still 16 lower than that of the standard 7950x so we are going a bit backwards here and this is an odd result that doesn't really make sense and I expect AMD will be able to address this issue and we find when disabling the second CCD that does in fact address the issue as the now simulated 7800x 3D result is the best of any CPU tested beating the 7700x by a one and a half percent margin though one percent lows were improved by six percent moving on to watchdog's Legion and here the 7950x 3D really impressed with 214 FPS making it 14 faster than the 1300 KS running ddr5 7200 and a massive 32 percent faster than the standard 7950x also in this title disabling the second CCD resulted in no real performance gain so this is a great showing for the 7950x380 I have to say the Hitman 3 Performance is fairly underwhelming here the 7950x was just a few frames faster than the standard model and we're seeing a similar thing when comparing the simulated 7800 X 3D to the 7700x so the 3D V cache appears worthless in this title or at least it was in the section of the game we use for testing and this meant the 13900 KS using 7200 memory was five percent faster than the 7950x next we have the Horizon zero Dawn results and here's N4 already performed really well and as we've recently discovered this isn't a memory sensitive game and it's probably one of the least memory sensitive games you're likely to come across looking at the 7950x 3D you'd think V cash doesn't help much here as we're seeing just a six percent boost over the 7950x when looking at the average frame rate however disabling the second CCD did Bruce performance by a further seven percent making the simulated 7800 X 3D configuration 10 faster than the 7700x and 28 faster than the 13900 KS using ddr5 7200 now for cyberpunk 2077 we've updated the testing to use the ray tracing Ultra preset as this can increase CPU load the margins though really aren't that different to what we saw with the previous test method using the medium preset here the 7950x thread it was just four percent faster than the 7950x allowing it to match the 13 900 KS using ddr5 7200 the rift breaker appears to be topping out at around 225 to 230 FPS but even so the 7950x3d saw an 18 increase in average frame rate compared to the standard 7150x so the 3D V caches are offering a nice performance gain here this also allowed the 7950x 3D to match the core I9 processors and moreover disabling the second CCD didn't help improve performance so the 7950x30 and 7800 X 3D should deliver very similar results in this title sadly performance in Counter-Strike Global Offensive does go backwards with the 3D V cash Parts as core frequency is the performance limitation here not cash capacity and this will be true for most older games we are still seeing one percent lows of over 300 FPS so I wouldn't say performance is an issue here but it is still lower than the standard 7950x last up we have a plague Tower Requiem and here we're seeing a massive 25 performance boost with the 7950x 3D over the standard model this was enough to see AMD overtake Intel's 13 Nitro KS albeit by just a six percent margin now disabling the second CCD did it get improved performance though this time by just a three percent margin finally here's a look at our 12 game average and as you can see the 7950x 3D and 1300k slash KS a very similar overall with no real difference in performance the 7800x 3D should be slightly faster again but overall there's really not much in it so the 1300k and these new 3D V cache CPUs are pretty well neck and neck AMD certainly hasn't blown Intel out of the water here but when looking at out-of-the-box performance they do have a very very slight Edge and it's also worth noting that the 7950x 3D was on average nine percent faster than the standard at 7950x while the 7800 X 3D looks like it'll be around 10 faster than the 7700x so some decent performance uplifts there but not massive overall so there you have it the ryzen 9 7950x3d it's an impressive CPU that does a good job of combining strong productivity performance with class leading gaming performance so if you're after a CPU that can do it all the 700 50x3d is going to be an attractive option but as we saw with the simulated 7800x3d results if you're just gaming I feel like the cheaper eight core part is going to deliver a much more consistent gaming experience or at least much more consistent performance and really even when the 7950x 3D performs as intended the 700x 3D will still generally be the faster processor as for which is the better gaming CPU the 7950x 3D or the 1300k slash KS well it really does depend on the game but overall I think in my opinion it's quite clear that they are very similar I'm not going to bother with a cost per frame comparison here we're really only interested in these two processors and value probably takes a back seat to Performance when talking about the absolute best choice for gaming these are kind of you no compromise type gaming Solutions the kind of description that we use to apply to Parts like the 8700k and 9900k still the 7950x30 is set to cost around 20 more than the 1300k which can currently be had for 580 U.S a decent z790 motherboard they look to start at around 230 dollars while amd's x670 balls they're more like 280 there so quite a premium for the motherboard the ddr5 memory used for testing the 7950x 3D so G skills ddr5 6000cl30 stuff that's about 175 dollars while the 6400 kit used for testing the 13900k that's about the same price about five dollars more so a negligible difference and that means you're looking at spending around 1200 us for the 7950x 3D combo and then about a thousand dollars for the 13 900k combo making AMD around 20 more expensive so a bit surprising they're going to say AMD so much more expensive than Intel and that is a pretty big pricing Gap that could see you go with premium ddr5 7200 memory with the 1300 okay and still save a hundred dollars U.S there's probably more tuning Headroom when it comes to memory time is with the 1300k as well and this is something I plan to look at in a few weeks when I get back from my holiday as long as there's no more damn products released between now and then and speaking of which my review was cut short as I did have to leave for a trip away so apologies for the lack of testing here I know there is a lot more to look at there's a lot more that I do want to look at and that is something I'll do in the near future but I do have a memory scaling Benchmark with the 7150x 3D coming up in the next few days so I did Squeeze that in so you could say a little something that I'd prepared earlier overall the 7950x 3D it's impressive but it doesn't exactly bury the 1300k and in fact the core I9 looks as viable as ever the 7800x3d though is probably going to be the better value option as it will come in a little bit cheaper than the 1300k combo while generally offering slightly better performance at least based on what we've seen here but of course there will be a 40 to 50 game Benchmark coming up shortly after the release of that part so make sure you stay tuned for that but if you want to buy it today well I feel like amd's kind of shot themselves in the foot as you'd probably just go with the core I9 1300k especially at its current sale price of 580 us a bit of a timely discount there anyway that is going to do it for this one but just a reminder we will have a lot more CPU content in the very new future so make sure you subscribe for that also if you'd like to support the channel directly and get some cool perks in return we have float plane or patreon links flows are in the video description you get access to monthly live streams until myself we do those

Yeah definitely waiting for the 7800X3D.

[u/jtmzac]

While its great to finally have all the nice fps charts I'm left with some really big questions about how the ccd's are managed.

After going through several reviews I've gleaned a few different things:

• There's the bios setting that lets you choose to prioritise the freq or v-cache ccd. This defaults to prioritising the v-cache ccd.

• The game bar is used to detect when a game is running which then causes the non-prioritised ccd to have all its cores parked.

• This parking behaviour requires the balanced power plan, since parking I'm guessing is a type of low sleep state?

• Testing is a bit all over the place with some testing changing the priority in the bios and others disabling one of the ccds.

What I'm not seeing in any review I looked at is what about setting the core affinity manually through task manager or process lasso??? The auto detection clearly doesn't always work quite right and having to reboot just to play a certain game is pretty dumb.

The other big issue is if the other ccd is parked, what about background tasks that aren't completely negligible on the cpu like running OBS? You would want them on the other CCD but if the cores are parked while gaming then is it effectively only an 8 core CPU?

The question is then if you override the parking behaviour with the bios settings or the high performance power plan and manually set core affinities (assuming this is actually possible) what is the impact to gaming performance?

BIG EDIT: Found a bunch of info thanks to the techpowerup review providing the more technical amd slides/instructions reviewers were given:

Core parking seems to be all being done through the window power management systems. This in theory should be able to scale up the active cores if needed but I don't know how well this actually works. There are a few parameters that can be tweaked to change this according to the slide and the microsoft docs.

The AMD driver is basically using the game bar game identification to tell the windows power system to park the non v-cache (or non-freq) cores. This seems to normally be something used for energy efficiency but in this case is a way to ensure things are being prioritised to the one CCD. The slides specifically say that it helps prevent cache misses. There seems to also be support for manual program overrides through registry entries.

I still am very curious about what happens to gaming performance if you disable all of this and just manually allocate games to the right threads/cores while the second ccd is active.

[u/Redd_Line_Warrior1]

A chip that is beating the 13900k in quite a few games. All while doing it at almost 50% of the power consumption. Not bad at all.

​

Either way, guess ill stick with my 5900x for another generation or two.

[u/_Antti_]

Not great, not terrible. It looks like the 7800x3D is going to be the real king.

[u/Nhadala]

The 5800X3D impresses me more there than the 7950X3D given how old the AM4 platform is.

I am curious to see how the 7800X3D will be.

[u/jedidude75]

7800x3d is going to be amazing.

[u/Sally_san]

I wonder if you could use process lasso as an alternative to disabling the entire CCD

[u/LoserOtakuNerd]

Well this just convinced me even more to wait longer for the 7800X3D. Not interested in dealing with multiple CCD problems and quirks.

[u/freethrowtommy]

Seems like 5800x3d is going to be one of those legendary CPUs that we see people holding onto for a long time, especially at the price compared to the new stuff.

If you are on AM4, seems like picking up that 5800x3d is still the way to go.
