AMD Ryzen 7950X, like it’s predecessor, the AMD Ryzen 9 5950X, is a 16-Core / 32-Thread processor featuring a host of new improvements including a new microarchitecture in the form of AMD Zen 4, much higher clock speeds, IPC improvement of close to 13 per cent, shift to a more efficient TSMC 5nm process, inclusion of current gen graphics cores across all SKUs, support for DDR5 and PCIe Gen 5.0 and a new AM5 LGA socket. With so many high-impact changes over the Ryzen 5000 series processors, the new AMD Ryzen 7000 series of processors has plenty of things that can really push it over the edge but it has an equal number of things that can go wrong. Hopefully, that’s not the case.
Moving to the more power-efficient TSMC 5nm process is going to help the Ryzen 7000 quite a bit on the power efficiency front. The AMD Ryzen 7000 series can eke out up to 49 per cent more performance on a 16-Core processor compared to the Ryzen 5000 series at the same socket power and core count. And if the performance were to be normalised, then the Ryzen 7000 series can manage to do so while consuming 62 per cent less power. Obviously, these improvements are not just because of the shift to the TSMC 5nm process but also because of all the architectural improvements. One of the easiest ways to see the improvement is by observing the clock speeds. The AMD Ryzen 9 7950X has a base clock speed of 4.5 GHz and a Turbo clock speed of 5.7 GHz. And this is without an improvement to the Precision Boost algorithm.
As for the other specifications, we can see that the L3 Cache per core has remained the same but the L2 Cache has been doubled and is private to each core. L1 Cache is also the same with 32K for the Instructions and 32K for data. The TDP has been raised by a huge amount to 170W compared to the 5950X which was designed for 105W. However, this number doesn’t indicate the power consumption. When AMD states a certain TDP for a processor, it indicates the caps for several parameters. In the case of the AMD Ryzen 9 7950X, a TDP of 170W means that the Socket Power is 230 Watts, the Peak Current is 225 Amperes and the Sustained Current can be as high as 160A. This is really going to do a number on the VRM of the motherboards, so always check the peak parameters of the motherboard’s VRM before you decide on buying one.
Lastly, all processors falling under the Ryzen 7000 family will have inbuilt graphics capabilities and instead of getting a really old GPU architecture, we’re getting RDNA 2 IGP Cores in all four processors that are being launched on the 27th of September. The core configuration is the same across all SKUs. Each processor will have two RDNA 2 cores which have a base clock of 400 MHz and a peak clock of 2200 MHz. RDNA 3 GPUs are right around the corner so one could have always hoped for more, but this is good enough. On to the benchmarks then.
AMD Ryzen 9 7950X PerformanceThe AMD Ryzen 9 7950X seems to have a lot of potential to beat the competition to become the reigning desktop processor across a wide variety of workloads. Let’s see how that pans out in the benchmarks.
We tested the unit on the following configuration: AMD RYZEN TEST RIG CPU: AMD Ryzen 9 7950X Motherboard: ASRock X670E Taichi SSD: WD SN850 1TB NVMe SSD HDD: Seagate FireCuda 2 TB ST2000DX002 RAM: 2x 16 GB Kingston FURY DDR5 @5200 MT/s Cooler: Deepcool 280mm AIO PSU: Cooler Master MWE 850W V2
Gaming
We tested the AMD Ryzen 9 7950X at 1080p resolution with HITMAN 3, Borderlands 3, Far Cry 6, Cyberpunk 2077 and Shadow of the Tomb Raider. Folks buying an top-tier desktop processor and graphics card such as the AMD Ryzen 9 7950X and the NVIDIA RTX 3080 probably aren't going to be gaming at 1080p resolution, so we'll be adding 1440p and 4K benchmarks once we get done testing those. From the 1080p gaming benchmarks we can see that the AMD Ryzen 9 7950X is at pay with the Intel Core i9-12900K in most benchmarks with the exception of one game -- Far Cry 6 -- where the Intel processor maintained a slight lead. As for HITMAN 3 and Shadow of the Tomb Raider, the Zen 4 processor seems to have gained a significant lead of up to 40 FPS.
