Before you buy the AMD Ryzen 7950X3D.

how much faster can gaming CPUs really get because lately it seems like the progress has been really really slow while the rendering and encoding side of things is becoming absolutely unhinged the gains when it comes to frame rate and gaming are far less inspiring well let's see if the 7950x3d can change that AMD have taken the secret Source from the 5800x3d which is that 3dv cache stacking and added that here to ryzen 7000 finally five months after ryzen 7000 has launched so this time around you'll actually have three 3D V cash chips to choose from and eight core a 12 core and a 16 core model that's the one that we're reviewing today but very very important that 12 core and 16 core model don't actually get additional 3D cache over the 7800 X 3D it's not like the more cores you buy the more stacked V cash you get although that would be pretty cool instead all three of these models here only have one of the two ccds with that extra 64 megabytes of L3 cache so I think we've all agree it's the 7800x3d which is looking like the better option out of the three it's the cheapest for starters and you're kind of getting the most 3D enhancement for the money and also because with amd's latest chipset driver you're only going to be gaming with the fastest 8 cores anyway so even if you buy the 12 or 16 core model those extra four to eight cores will literally be asleep when you're running a game in fact I found the current public driver to already be doing this with the non 3D 7950x so look we are kicking things off with the 16 core 7950x3d today but just keep that in mind the new chipset driver disables the non-3dv cache CCD whenever it's under gaming loads as for the test bench I've tested all CPUs alongside an RTX 4090 more specifically the liquid-cooled Supreme Ax from MSI for ddr4 CPUs I've used 3600 cr16 and for ddr5 parts including Intel 12th and 13th gen I've used 6000 megahertz cr36 so let's kick things off with some competitive Games first these are usually the games where you'll see the most CPU scaling and for these ones I've also included the average latency on the left there as well so PC latency you can think of that as the processing latency of the CPU GPU and the game combined but this doesn't include the latency of your mouse or your monitor it's purely how fast your system can prepare and finish rendering a frame effectively you can think of the right side of this graph showing the smoothness of the game and the left side showing the responsiveness so here in OverWatch 2 yeah we do see the new ryzen 7950x3d right at the top of the chart however it is by a very slim margin a good chunk of these CPUs are running into that 600 FPS cap despite running these benchmarks at 1440p versus the 5800x3d inputs are one millisecond faster on average and one percent lose aramir 7 FPS ahead so barely again here at all if though you're upgrading from a ryzen 2000 or 3000 CPU then you will definitely see a difference five millisecond faster input and roughly a double in frame rate however that's also what you'd see if you were to upgrade to the 5800x3d in Modern Warfare 2 using the built-in Benchmark I actually found the 5800x3d to be slightly faster on average compared to the new 7950x3d this is also something that I went back and retested but I kept getting the same result very interesting to see for sure and one more reason to hang on to that 5800x3d if you currently have one as for f122 despite running 1440p High settings here the GPU usage for our RTX 4090 was only 83 when paired with the new 7950x 3D so there is still some CPU bottlenecking at play having said that everything from the 5800x3d and upwards basically shows the same experience between the old and the new stuff there's about a 3.5 Improvement on average and PC latency is basically identical maybe if we ran this at 1080p medium to low settings we'd see some more aggressive scaling here but not even the best Sim races in the world play with those in valorant the 7950x3d finally cracks that 1000 fps mark on our spike plant simulation with one percent lose over 600 FPS again though experience wise there's basically no difference here versus the 5800 X 3D especially when the difference in latency is just half a millisecond but for what it's worth the 7950x3d is the faster chip now keep in mind if you're playing an actual 5v5 match you'll see frame rates far below this but the scaling for each CPU should be about the same we also see surprisingly good scaling in cyberpunk 2077. here the new 3D chip was five percent faster on average versus the non-3d part and 13 faster when it came to the one percent lows at this point as well the new 7950x3d almost relieves all CPU bottlenecking with these settings GPU usage for r4090 was 95 on average versus around 92 percent for the 5800 X 3D now there are some instances where Intel's 13900k ends up on top of everything in Red Dead Redemption 2 for example I found the 5800 3D and 17950x3d to be virtually identical but then the 3900k ends up at 5 faster than both on average similar story in Doom Eternal 3 900k out on top with the new and old 3D V cash chips basically pushing the same performance so there are some instances just as we saw with the 5800x3d with that extra L3 cache doesn't really help a lot then in Rainbow Six even less convincing gains here the margin between the top five are incredibly slim but maybe the biggest difference here out of all of these CPUs is power consumption and surprisingly the 7950x3d doesn't pull that much power at all in valorent just 76 watts and that's also while pushing out 1000 fps now apart from the additional L3 cache there are a few other differences here over the standard 7950x the default temperature target has been lowered from 95 to 89 degrees C and I will mention it hits that really really easily despite using a 360mm cooler at 2000 RPM on an open bench the 7950x3d hit 89 degrees within just a couple of seconds of running cinebench and it did that while not even pulling 160 Watts so the heat management for this processor looks a little bit funky if I'm honest those kind of numbers with a 360 mil cooler just don't really add up in particular the CCD with the 3D V cash stacked on top was warming up extremely easy and at least in this scenario around about 20 degrees hotter than the CCD that doesn't have that extra cash so something is quite odd here especially compared to the regular 7950x which has pretty even temperatures across both ccds so more even heat distribution within the chip a higher temperature Target as a result the 7950x can sustain higher clock speeds and performance while under these all-core workloads so if you're looking for the most multi-threaded performance possible and you're really serious about productivity and faster processing times the standard 7950x is the slightly faster chip in cinebench it was around nine percent faster than the new 3D chip which might hint of why AMD price to both products the same single threaded performance on the other hand is about equal since that heat and power management doesn't really come into play here 3d motion tracking is a great example of that this task only runs on a single thread oddly here though I still found the regular chip to be a tiny bit faster and then in Adobe Media encoder generating proxy files here for video editing the 7950x 3D sits right alongside the 3900k and 7950x as you would expect so for the most part we are getting that unreal 16 core ryzen 7000 performance it's only the full ball rendering and encoding stuff that seems to take about a five to ten percent penalty versus the non-3d chip that chip can boost a little bit higher and get a little bit warmer so do expect more performance alright so the 7800 x3d is probably the one that you want to be waiting for here to be honest the 17950x 3D it's a bit of a weird CPU like I guess if you want the gaming benefits that the 3D V cache provides but you also want 16 cores I guess that's what this is trying to serve but at the same time you know the gains that we're seeing honestly from the 3D V cache this time around don't seem that impressive as what we saw with the 5800x 3D and in most cases the 5800x3d is still there to play like if you're currently are on the am4 platform and you're looking for an upgrade that chip is just an easy easy pick it's currently around 330 dollars you know just update your bios and drop it in your system and there's no need to additionally purchase a new am5 motherboard along with ddr5 so I am looking forward to seeing what that 8 core variant can deliver especially because these 3D chips are unlocked this time around so potentially you could tweak them to the same clock speeds as what we have here or maybe even faster now one CPU that I didn't have in the chance for this one is the 13600k for what it's worth the gaming performance there is extremely similar to the 13900k and if you are looking to build something from the ground up that's focused around gaming that and the 5800x3d are currently the two that I'd still be sticking with but yeah that's pretty much it as always a huge thanks for watching and I'll see you all in the next one
