  • 4070 Super performance issue

    I just got myself a MSI RTX 4070 Super and got very disappointing PerformanceTest (latest build) 3D Graphic benchmark scores between 23800 to 24000 which are supposed to be around 30000. The mainboard is a Asus Rog Strix B550 which supports PCIe 4.0. CPU is a Ryzen 9 3900x (20 lanes). There is no other card in the PCI slots but there are two M2 used. Can someone give me a hint what to do to get the 4070 to the performance it usually has? Thanks.

    Yes it is a little low.
    Here's the distribution.

    This page covers all the common performance issues

    Common ones that keep occurring are high temperatures, bad drivers, 3rd party blotware, wrong PCIe slot & Windows power profiles.

      Thanks a lot for the link. I will check all the potential issues mentioned there and report back.

        I can't find anything. CPU 3900x (Score: 31614) and Memory Corsair CMK16GX4M2B3200C16 (Score: 3111) are performing fine and none of the things mentioned in the article seems to be wrong. Also the M2s do not interfere with the PCI Lanes for the main PCI 4.0 x16 slot. Only thing I found is that this site is saying my 3900x might be a bottleneck for the 4070 Super at 1440p: https://pc-builds.com/bottleneck-cal...ing/2560x1440/

        Maybe I should get a 5950x, this would be a significant upgrade anyways.

          I did another run with 3D PerformanceTest 11 for 3D benchmarking, this time with the Nvidia overlay display for utilization of CPU and GPU turned on:

          DX9: CPU: 8% GPU: 50% (1080p)
          DX10: CPU: 8% GPU: 95% (1080p)
          DX11: CPU: 8% GPU: 95% (1080p)
          DX12: CPU: 8% GPU: 45% (1440p)
          CPU Compute: CPU: 8% GPU: 80-95%
          OpenCL Particle: CPU: 8% GPU: 65%

          It seems PerformanceTest 11 is only using a single core of my 12-core 3900x and therefore the CPU bottlenecks in DX9, DX12 and OpenCL Particle tests what would explain the poor result of 25256 points in 3D overall benchmark. Not sure what to make of it, because is a modern graphic card (like the 4070 Super) supposed to match with a single core processor (it really is, if only 1 core of the 3900x is utilized) in the year 2024? Most games and apps nowadays use multithreading, so I'm not sure how much this score says about a CPU bottleneck in everyday performance if using usually 2 or more cores in games or apps.

          Nevertheless the score is behind most other 4070 Super card scores in the database, so I guess that's because most other benchmarks were done with CPUs with a stronger single core performance and therefore less bottleneck from CPU?

            Yes, you have teamed up a 5 year old CPU with a current GPU.
            The Ryzen 9 3900x is currently the 653rd fastest CPU model for single threading. So pretty weak. Some of the tests do do some threading, but not enough to completely remove the CPU from the equation.

            We have been doing some work on the DX12 test. In the next major release or PerformanceTest we'll be moving more of the load to the GPU.
