Gamers report that ARC A770 VRAM speeds run at 2000mhz instead of 2100mhz
Intel’s Arc A770 series graphics cards are available in 16GB and 8GB memory versions. In addition to the difference in capacity, the frequency of the memory used by the two is also different. The 16GB version of the Arc A770 comes with faster 17.5Gbps GDDR6 memory, while the 8GB version uses 16Gbps. However, many users have reported that their Arc A770 limited edition graphics cards have problems with reduced memory frequency, and it is not clear why.
These users reported the issue to Intel on Github. The Arc A770 limited edition graphics card they looked at with GPU-Z had a memory frequency of only 2000MHz and bandwidth of only 512GB/s. After conversion, the equivalent frequency of the video memory is 16Gbps, which is the frequency of the 8GB version of the A770, and the correct frequency of the video memory of the 16GB version of the video card should be 2187MHz, and the memory bandwidth should be 559.9GB/s.
This problem is not a simple GPU-Z detection error. Other software detects it as well. At present, the developers of GPU-Z are studying this problem. It is unclear whether it is the software detection error or the API or driver reporting the wrong video memory frequency. Of course, there is a possibility that the video memory is really downclocked, and Intel has not responded to this issue yet.
