AMD Ryzen 9 7950X3D processor with 3D V-Cache technology, 16 cores/32 skewed threads, Zen 4 architecture, 144MB cache, 120W TDP, up to 5.7GHz boost frequency, Socket AMD 5, DDR5 & PCIe 5.0

Product Information

Compared to the more expensive chipsets, the AMD Ryzen 9 7900X3D absolutely holds its own with the 7950X3D and the 13900K, with the largest gap visible seen with how AMD's flagship handles Returnal. This is likely due to the fact that the 7950X3D utilizes an additional four cores and eight threads, and Total War series has always been Intel's strongest gaming benchmark, which remains the case here. Stress testing tools like Cinebench R23 push the processor to its engineered limits in terms of power use and operating temperature, and I use these to make sure that every chip is pushed to full 100% CPU utilization under load to determine the minimum and maximum amount of power the processor uses (measured in watts) and the minimum and maximum temperature recorded (measured in Celsius).

Creative performance is a measure of how well the processor performs in several popular creative workloads like Handbrake, Blender, and Adobe Photoshop. Where possible, I explicitly disable GPU accelerated operations or test rendering using the CPU by itself.Having the on-chip integrated graphics present is highly useful for troubleshooting and, if you aren’t going to run games, it can save you from having to buy a display adapter, which cuts costs. The IGP that AMD opted to use on its processors, however, is relatively weak. The last-gen Ryzen 7 5700G has the fastest IGP of any desktop CPU, and while we don’t necessarily need that much performance in every desktop CPU, it’s too bad AMD opted for as weak an IGP as it did. AMD's Ryzen 7000X3D gaming-focused processors finally have a release date - or rather, two release dates. The Ryzen 9 7900X3D and 7950X3D will debut on February 28th, with the 7800X3D arriving on April 6th. AMD designed the Ryzen 9 7950X3D based on its Zen 4 microarchitecture, which I went over in greater detail in my review of the Ryzen 9 7950X, linked above. Instead of going over the Zen 4 nuances again (hit the review for more detail if desired), let’s focus on what’s unique with the Ryzen 9 7950X3D. In most CPU tests, however, the cache is not that helpful, and this is what paints the worst picture of the Ryzen 9 7950X3D. Out of all of our CPUs tests, the Ryzen 9 7950X3D is beaten by the Ryzen 9 7950X in all of them except one. That one is the single-threaded POV-Ray 3.7 test, and admittedly that's within the margin of error.

It's simply the best gaming CPU by performance you can buy on the consumer market and that's not likely to change for the rest of this processor generation, at the very least. Only fusing the SRAM onto one CCD also reduces manufacturing costs, as the hybrid bonding process and additional chiplet make this an expensive technology. AMD also says that using two V-Cache chiplets doesn’t provide enough performance uplift to justify the extra costs. When you factor in the cost of upgrading to the new AM5 platform, the Ryzen 9 7950X3D only makes sense if you are upgrading from an AMD Zen 3 or 11th-gen Intel processor or earlier, since you'll need to buy a whole new setup to get a newer processor from either brand. If you've got a 12th-gen Intel chip, though, making the jump to the AM5 platform for this processor alone is going to be a pricey upgrade.The Ryzen 9 7900X3D has also been crafted for high-performance gaming and creating. Its cache capacity is 140MB, paired with twelve cores, twenty-four threads, and boost speeds up to 5.6GHz. AMD’s Collaborative Processor Performance Control (CPPC2) interface already ranks the fastest cores as the highest priority, enabling the OS to schedule threads into these ‘preferred’ cores first. Not all Ryzen cores can reach the rated peak frequency, so this tech is critical to ensure strong performance in lightly threaded apps, like gaming. The tuned setting did deliver higher performance, but only in the same way you can tune an F1 car to run above tolerances only to explode as it crosses the finish line. I could catch some higher benchmark numbers, but the system was in no way stable. The cache clearly does not help enough to give the Ryzen 9 7950X3D the performance advantage in any other CPU test in our suite. At the same time, its lower TDP and heat limit cause the 7950X3D to operate a bit slower and perform worse in almost every test except that one. The Ryzen 9 7950X is slightly faster in many of these tests, but, considering how much cheaper that chip is at list price, it’s a bit of a no-brainer which is the better value in this scenario.

There are some tradeoffs to attaining the leading gaming performance, though — some games don’t benefit from the 3D V-Cache, and the chip isn’t as fast in productivity apps as competing Intel chips. The 7950X3D also suffers from many of the pain points we’ve already seen with the fledgling AM5 platform — the motherboard ecosystem is more expensive than Intel’s offerings, and the strict requirement for DDR5 significantly increases costs compared to Intel’s DDR4-friendly platform. If the software detects a certain high level of thread utilisation, however, it will spin up that dormant chiplet and bring it online if its extra core count is needed.The Ryzen 9 7950X3D pretty much matches the 7950X in Blender and Adobe Photoshop and Adobe Premiere tests, though it lags a bit in VRay 5 (though not by that much). Where it really shines though is with HandBrake 1.6. This is one of the creative tests we use where we get to measure it's true real-world performance on a creative workload, especially one that is highly CPU dependent. Ultimately, the reduced memory latency means that you're getting a chip that runs cooler, draws less power, and performs better thanks to the addition of the second generation of AMD's V-cache. However, AMD later retracted this as an internal issue, stating that more information on the release date would be unveiled shortly, but that the official debut month will remain as February. We now know, the release dates are as follows:

PlaneInTheSky said:The cons just weigh too heavy for me to even consider the CPU or the AM5 platform. What's also so notable about the 7950X3D is that while Intel's latest processors have been outstanding, that performance is far more a function of just throwing power at the problem, literally, than it is some kind of technological magic behind the scenes. I tested the AMD Ryzen 9 7900X3D inside of a newly built machine utilizing Kingston Fury Beast DDR5 RAM, an Nvidia RTX 4090, and a brand new RM1000X PSU. The chip was utilized heavily for gaming in the benchmarked titles as well as in games such as Mortal Kombat 11, Cyberpunk 2077, and Tekken 7.

AMD takes a bite out of Raptor Lake.

Or maybe the Ryzen 9 7900X3D or Ryzen 7 7800X3D might be. I've yet to test the other cache-heavy chips, but if they can deliver the same gaming and efficiency uplifts as this one then they're going to make more sense to a PC gamer. The 7900X3D has the same asymmetrical chiplet layout, so has the same compromises for productivity, but the 7800X3D is a pure 3D V-Cache gaming beast. If you ain't rendering in Blender, that's likely to be the best of the bunch for you.
