  • [GURU3D] PlayStation 5 Tech Details - 8x ZEN2 cores, RDNA2 with 2304 shaders (16GB GDDR6) + 825 GB (5.5 GB/s) M.2 SSD

    PlayStation 5 is based on eight CPU cores (AMD’s third-gen ZEN2 Ryzen line) and a custom GPU based on custom AMD’s Radeon Navi hardware (in the presentation the presenter actually stated 9 cores at one point but we assume that was a mistake). Sony works with AMD on the hardware processing side of the console, fitting it with "Zen 2" CPU cores similar to the processor cores of the current Ryzen 3000 generation desktop processors. The processor thus holds eight ZEN2 cores, we assume SMT (Hyper-threading) enabled as that would account for 16 logical processors or threads.
    ...
    The GPU is listed having 36 (new Xbox actually has 52) compute units, if the shader clusters hold 64 units per cluster (and we're pretty certain of that) then that accounts for 2304 shader processors for PS5 running at clock frequencies that can hit 2230 MHz on the GPU and 3.5 GHz on the processor cores (max boost values). Both the CPU and GPU will thus get variable (boost) frequencies, much like we have had for years on our desktop PCs. For the GPU that also means different as game and max boost frequencies. We think the GPU will be more at a sub 2 GHz 'game clock' rather than that (really impressive) 2230 MHz. This is an interesting clock frequency to learn from with BIG NAVI in mind eh? Anyway, that brings the new console towards 10.3 TFLOPs of compute perf (GPU), where the Xbox claims 12 TFLOPS.

    Certainly a jump this gen, the same for the XBox Series X. Though looking at the new Xbox specs, it does edge out the new PS4. I think they took this gen very seriously and wanted to be on top, its not by a huge margin but I think they can claim the crown.

      It's definitely a good thing. The PS4/Xbone were underwhelming. Both launched with glorified tablet CPUs and GPUs which at the time were lower-midrange that were a generation old before the consoles even launched.

        Yeah they were super lackluster, I was only ever excited about last gen as I was waiting for certain games...the hardware did not excite me at all. Even though I doubt I will buy into this gen due to lack of time and I prefer PC gaming...I am excited about the specs. I also think it will help gaming overall especially when it comes to porting from Console to PC (Not that I am a fan of that).
