AMD Ryzen 7 7800X3D vs. Ryzen 9 7900X3D vs. Ryzen 9 7950X3D, Gaming Benchmark

[Music] welcome back to Harbor unbox today we are testing the ryzen 9 7900 X 3D it was released a little over a year ago now so the timing feels right seriously though this was never a CPU that I was interested in because at $600 us it just didn't make sense just six cores with access to that 3D vcash and we knew this even without reviewing it because well we knew we needed to know about this series with the 7800 x3d and 7950 x3d not only that but AMD also only sampled the 7800 x3d and 7950 x3d they didn't sample this one which meant if we wanted to get the 7900 x3d we were going to have to part with $600 us and as I said we kind of already knew that that was a CPU that at that price just wasn't worth buying so we we didn't buy it and also at the time there was just more interesting products to cover but anyway it's a year on now and we're finally looking at it but before we do today's sponsor spot is brought to you by thermal take and their CT e600 midtower case as part of their centralized thermal efficiency series it features a dual chamber design making it big on the inside with loads of room for not just building a new pc but also managing all the cables with ease the CTE e600 includes a PCI 4.0 Riser cable and floating GPU bracket for vertical GPU mounting and can support up to 40 18 120 mm fans or 12 140 mm fans and despite the unique design uses high quality materials including tool-free perforated mesh and tempered glass there's also room for up to a 420 mm Radiator in the front rear bottom and all back tray allowing for plenty of customization and cooling so for more information please check the link in the video description okay so as I've made pretty clear at this point $600 us that thing's just not worth buying you were better off going with the 7950 X 3D for $700 us it was a mere 177% price increase it landed a 33% more Cs and more crucially for gaming you got the two extra 3D vcash enabled cores like what you get with the 7800x 3D alternatively you can get the 7800x 3D that was available upon launch for $450 us so Not only was it a lot cheaper than this thing but it was guaranteed to deliver better gaming performance as it packed 8 3D vcash enabled cores all in the one CCD whereas the 7900 X 3D was limited just six cores uh with the 3dv cache in the primary CCD whereas the secondary six core CCD didn't have the 3D V cache so there was scheduling issues there all kinds of problems that would compromise performance or could so that was that really well until the pricing changed of course and changed it has in a rather big way the 7800 X 3D can now be had for as little as $370 us and the 7950 x3d $580 which is near enough to a 20% discount for both parts but those aren't the biggest discounts the 7900 X 3D has seen 35% slashed off its price dropping to just $390 us making it a mere $20 more than the 7800 x3d but it packs an additional four cores and this pricing adjustment has caused many of you to pause and consider the 7900 x3d the only problem being there's very little Benchmark data online as this part never had a review program so I finally went out and got one and then threw our battery of gaming benchmarks at it to see how it compares to not just the 7950 x3d and 7800 x3d but also the rest of the ryzen 7000 series for testing we're using the gigabyte x670 orus Master motherboard running the latest F22 bios and for the memory we have a 32 GB ddr5 6000 cl30 hit then for the GPU we're of course using the GeForce RTX 490 as it's our best tool for measuring the gaming performance of CPUs and this means we'll also be testing at 1080p if you don't understand why reviewers test this way and you'd like to learn more then we do have a video in the description that you can check out rather than waste time explaining all the benchmarking Basics here okay let's get in the data first up is Boulders Gate 3 and this has been a great title for the x3d chips the 7800 x3d for example was 52% faster than the 7700x and that's obviously a very big margin however whereas the non-3d vcash parts are all quite similar in terms of performance the faster x3d variants see more variance in the results the 7800 x3d and 7950 x3d delivered similar performance but the 7900 x3d was slightly slower trailing by a 7% margin and this is because there's less 3D vcash enabled cores just six rather than eight and the game is scheduled to only run on the 3D vcash enabled cores so the CCD with the 3D vcash out of Interest though I did disable the non-3d vcash CCD on the 7900 X 3D creating what would be a 7600 x3d if such a part existed and doing so further reduce the performance as presumably the second CCD was being used to handle background tasks or really anything not relating to Boulders Gate 3 even so the 7600 x3d if it existed would be almost 30% faster than a 7950 X in this example moving on to cyberpunk 2077 Phantom Liberty we start to see some examples of why it's hard to predict the performance of these processors the Dual CC design of the 7950 x3d costs it some performance here as the 7800 x3d is up to 6% faster but reducing the 3D vcash core count to six further reduces performance here as the 7900 x3d was good for 171 FPS making it 12% slower than the 7800 x3d then if we again disable the second CCD on the 7950 x3d again effectively making what would be a 7600 x3d performance actually improves by 6% as we're no longer paying a penalty for the cross CCD communication as those additional slower cores aren't useful in this example still it's a bit all over the place but essentially for maximum performance you want eight 3D vcash enabled cores and with scheduling not being perfect here ideally you want just a single core complex di next up we have Hogwarts Legacy and performance here does improve with additional cores not significantly so but we are seeing better performance with the 7900 x3d and 7950 x3d over the 7800 x3d for example and the simulated 7600 x3d is slower again we also saw similar performance Trends with the non 3D vcash models the 7900x 3D was 4% faster than the 7800x 3D in this example so not a massive margin but this is the first example we have seen where the 12 core part is faster for gaming the Star Wars Jedi Survivor results are interesting as here the 7800x 3D and 7950 x3d delivered similar performance the 7950 x3d was just 3% faster when comparing the average frame rate however the 7800 x30 was still 11% faster than than the 179900 x3d as here we see that the game does benefit from having eight 3D vcash enabled cores this performance deficit wasn't as pronounced with the slower non-3d vcash CPUs now ACC is a game that doesn't utilize core heavy CPUs that well but it does benefit from improved cach performance and we see that here with the x3d chips again the 7800x 3D and 7950 x3d are very similar in terms of performance and while the 7900 x3d isn't far off the mark it did slip a little bit coming in 4% slower than the 7800 x3d so not a big deal there but just a little bit slower interestingly though if we do disable the second CCD on the 7900 x3d again creating a 7600 x3d if there was such a thing performance does fall away further and that's not something I expected to see in this example Spider-Man remastered sees little in the way of a performance benefit with the x3d chips we are using rate tracing here which does limit the performance of the RTX 490 but we are still typically looking at over 150 FPS the 7900 x3d is comparable to the 7800 x3d and 7950 x3d and we see when're disabling the second non 3D vcash enabled CCD that the performance does decline in this example particularly so for the 1% lows now this is a bit of an odd one that caused me more than a few headaches resulting in multiple clean Windows installation in an effort to fix the 7900 X 3D's performance testing with a plague tail requium saw the 7900 x3d massively underperforming to the degree that doesn't really make sense for a few reasons firstly duel ccds don't appear to be an issue here is the 7950 x3d was able to match the 7800 x3d but also having just six cores with access to the 3D vcash doesn't appear to be an issue as disabling the second CCD on the 17900 x3d resulted in pretty great performance with the simulated 7600 x3d But it gets even more confusing as we do see similar margins with the non 3D vcash parts and in particular the 7900x is weaker than you'd expect trailing even the 7600 X though this time the 7700x was faster than the 7950 X so that does appear to be a dual CCD issue but as for why the 12 core parts are so slow this has to be some sort of scheduling issue with this particular particular title The Assassin's Creed Mirage results on the other hand are pretty easy to explain with the x3d parts it's quite clear that having eight cores with access to the larger L3 buffer results in around a 10% performance boost then without the 3D V cache all zen4 parts cap out at around 175 to 176 FPS regardless of the core count or configuration and it's a similar story when testing with Watchdog Legion again having an additional two cores with access to the larger 3D vcash boost performance by around 15% so if you're going to purchase an x3d processor for maximum gaming performance you ideally want to do so with a model packing eight cores per CCD Hitman 3 has more interesting results for us firstly this game doesn't benefit significantly from the additional L3 cache the 7800 x3d for example is just 10% faster than the standard 7700x then we see that the game run at around 230 FPS with six zen4 cores and around 240 FPS with eight cores or 260 FPS if you add in the 3D vcash however with just six 3D vcash enabled cores performance is capped at 245 FPS and then if you add in some scheduling issues into the mix as is the case with the 7900 x3d performance drops to what we see with the standard 7600 X so the results are a bit all over the place here the Counter-Strike two results are also quite strange mostly because there is a noticeable performance uplift from the single CCD models such as the 7600 X and 7700x to the Dual CCD models in the 7900x and 750x it would seem as though scheduling is working really well here the game is running on one CCD while background tasks are all taken care of by the second it's a bit like how APO enhances Intel's p and E core design and we see a similar effect with the x3d parts though here the simulated 7600 x3d is a bit slower than the 7800 x3d as the 8 core enabled 3D vcash part is able to reach New Heights though the 7900 X3 is still faster again if only by a small margin finally we have Call of Duty Modern Warfare 3 and these results are probably the most straightforward to explain in short the game benefits from having more CES with the duel CCD design and I believe this is down to scheduling working well again the game runs in one SE CD with everything else taken care of by the other giving the 12 and 16 core Parts an advantage whether that be with or without 3D vcash in short the 7900 x3d does well here delivering a small 4% boost over the 7800 x3d though it was just 5% faster than the standard 7900x now here's a look at the 12 game average and the results look pretty much as expected the 3D vcash really helps to accelerate gaming performance and it works best when eight cores can access the larger L3 buffer as is the case for the 7800 x30 and 7950 x3d the 7900 x3d on the other hand it isn't nearly as good when it comes to Peak gaming performance despite performance overall still being very good after all the 7800 x3d and 7150 x3d were only around 7% faster on average though they do look much more impressive when compared to the non 3D models for example the 7800 x3d was 24% faster than the 7700x while the 7900x 3 was 177% faster than the 7900x so still an impressive uplift but not as significant as you might have expected so there you have it the results overall aren't terribly surprising it makes sense that the 7900 x3d isn't nearly as potent as the 7800 x3d or 7950 x3d for gaming also my sincere apologies for the amount of times you've heard me say x3d in this video I did try to keep that to a minimum but yeah pretty tricky for this sort of content anyway with just six cores enabled or six cores able to access the 3D vcash the performance overall you know it was still excellent but there's certainly a performance penalty to pay there and while not massive for those of you primarily gaming the 7800 X 3D does make more sense frankly I've never been that Keen on the 7950 X 3D really both CC should have been armed with 3D vcash that would have been a killer product but even so it can still be every bit as fast as the 7800 x3d for gaming though in some instances you might have to tackle the scheduling issues manually with a program such as process lasso the 7900 x3d still has the same scheduling issues as the 7950 x3d at least in some games with the added bonus of the six core penalty so again while performance overall is excellent It's Not Without its quirks the Dual CCD x3d chips were always a bit odd with just one of the ccds featuring the 3D vcash and typically speaking the larger L3 cache is most useful for improving CPU limited gaming though I'm sure there are application workloads out there that also benefit from more L3 cache we just haven't come across them and admittedly productivity testing isn't really the focus of what we do here at Harbor unboxed the point is though the most optimal zen4 processor for gaming is the 7800 X 3D it ensures maximum performance in all games at least relative to other zen4 processors there are certainly examples where the 12 and 16 core models are faster but with a heavy Reliance on AMD software scheduling the results end up being a bit all over the place and this makes the 7950 x3d and 7900 x3d Niche products in my opinion is they really only make sense for people who are serious about gaming on their productivity workstations that said with the 7900 X 3D priced at just $390 right now it's the exact same price as the 7900x so you obviously wouldn't buy the non-3d version moreover the 7950 X costs $550 right now and that's a 40% price hike for a 33% increase in core count and then if you want the 7950 x3d it's almost 50% more than the 7900 x3d so while I would normally recommend you avoid the 7900 X 3D it's a seriously interesting part at $390 but even so I'm not exactly sure who I'd recommend buy it if your focus is gaming then the 7800 x3d is not only faster but also slightly cheaper so for gaming just get that it's a simpler solution that ensures maximum game performance as you avoid the Dual CCD scheduling headaches the 700 x 3D makes the most sense in my opinion as a productivity processor so works best for productivity application but then in that instance you are less likely to benefit from the 3D vcash it seems to mostly enhance gaming performance not universally but that's where it seems to be of most benefit but then the standard 7900x it's priced at $390 as well so if you're looking at a 12 core part a zen4 part for productivity purposes you might as well just get that big L3 cache because essentially you're getting it for free as the 700x 3D and 700x cost the same am out so yeah in that situation why not it really is amd's best value Zen 4 based productivity CPU right now and well that's that so bit of a niche product uh again can't really recommend it for gaming because there are better solutions for gaming such as the 7800 X 3D and if you want to game and do productivity then yeah probably worth paying the premium for the 7950 X 3D depending on you know if time is money and all that on the productivity side anyway bit of a bit of an odd tough recommendation on this one but of course let me know what you guys think about the 7900 x3d at its new $390 us price point I mean it's not an official price point it certainly could go back up but it is currently at that price and has been for a little while now uh and it's one of the more discounted Zen 4 processors so yeah let me know what you think very keen to get your feedback and is it something you were considering are you still considering it do these results change your opinion about it in any way let me know I'll read uh but yeah that's going to do it for this one float plane patreon if you want to get more harun box goodness you can sign up to either one of those you get access to our monthly live stream Tim and I get together and answer your questions live and talk about whatever interesting things have been happening throughout the month we do behind the scenes content q&as and we have an awesome Discord server great community over there if you want to talk Tech and well basically anything else uh yeah that's going to do it I'm your host Dave see you next [Music] [Music] time
