when all 16 cores and 32 threads are under load, but in practice we see it running at a higher speed of 4.

AMD Ryzen 9 7950X3D review: Team Red retakes the lead with

This is AMD’s innovative stacked cache technology, that allows the X3D CPU models greater access to cached memory. Increase the graphics quality to max settings and the resolution to 4K and even the RTX 4090 won't be able to keep up with any of these processors, and the advantage of 3D V-Cache shrinks considerably and eventually you'll find yourself GPU-locked regardless of what CPU you're using. Like 7950X regular, we believe AMD ought to have let it run mostly free of wattage constraints – a 170W TDP 7950X3D would certainly benchmark that little bit better… but then what would be the point of 7950X regular? Esports players especially will love the 7950X3D, as this chip performs best under the exact conditions most commonly used in competitive esports titles.That’s because Intel’s latest Raptor Lake architecture has moved the gaming needle to the right, limiting X3D’s comparative gains. The added cache chip and its position on top of one of the CCXs introduce power and heat considerations to the CPU that didn’t exist before. The lower power consumption measured during Adobe Premiere and Cinebench gives the Ryzen 9 7950X3D better overall performance per watt and slightly better overall energy efficiency. Quite simply, AMD does so much more with far less power than either of the competing flagship processors, and you don't have to accept lower performance as a tradeoff. These efforts in the past have seen mixed results with, at the best of times, a modest performance gain occurring and, at the worst of times, nothing really changing.

In practice, this seems to work very well behind the scenes without any adjustments from the user beyond installing the upgraded drivers when you install the chip, but there still might be some optimizations that need to be worked out, especially when it comes to benchmark tests, but we'll get to that in a minute. In other words, AMD thought about 3D V-Cache from day one; it cannot be retroactively ported over to other chips lacking TSV transmission support. Obviously, the CPU is only one component in the equation of PC gaming performance, and these test results are based on games running at the lowest graphics quality at 1080p with an extremely overpowered graphics card (an RTX 4090) to reduce any fps bottleneck you'll get from the GPU. Synthetic single and multi-core benchmarks test the performance of specific instruction sets and processor operations like floating-point calculations using benchmark tools like GeekBench, Cinebench, and PassMark.Retail processors with a 65W TDP will come equipped with a default cooler in the box, which should be plenty, especially if you are using it for work, casual gaming, or internet browsing. This is identical to the Ryzen 9 7950X, but the Ryzen 9 7950X3D’s IGP can gain some small benefit from the added 3D V-Cache. System scores are middling more than impressive, as these synthetic tests rely heavily on peak frequency.

I began working on computers owned by immediate family members and relatives when I was around 10 years old. It’s always better not to have any additional software used, as is the case with single-CCX X3D chips, and we’ll examine how well AMD’s software works in the benchmarking section. This all leads to reduced latency and improved performance, as there is a significantly shorter wait time for new information in comparison to fetch rates from your RAM. To be clear (and contrary to our earlier theorizing that we mentioned in the Editors' Note up top), the Ryzen 9 7950X3D's IGP doesn't have access to the L3 cache on the processors, but just like the 3D V-Cache can help gaming performance with a graphics card, it can help the IGP perform better in the right scenarios, too. Also sporting the 3D V-Cache technology, this is a great processor for mainstream gamers and streamers.Starting with the Ryzen 7000 series, AMD began adding low-power IGPs to all of its Ryzen desktop processors. The regular AIDA test doesn’t readily differentiate between CCDs so we can’t calculate the extra latency of hopping on over to X3D. This is hurt by the high idle power consumption, however, which never drops below 97W with the system sitting idle at the desktop for prolonged periods. This makes for a much more sensible average when all is said and done than averaging absolute scores where one CPU test with one very large result can badly skew a final average.
