Hello. Why is my mobile card AMD Radeon HD 8570M 2GB in section BUS Width shows 32 bit and 64 bit should. Screenshot attached.
I have Windows 10, laptop Lenovo G500.
I suspect either that it is a detection error, or Lenovo customized the chip to use a 32 bit memory interface.
I wrote to tech support of the program GPU-Z, that's what I said:
Good question. Looking at other results, it seems that bus width detection for your GPU is working correctly in GPU-Z.
Is it possible that you check with the laptop manufacturer on why it is 32-bit only?
and it should be 64 bit
Since these are OEM specific implementations of the chip by Lenovo, you should contact them to clarify the specs of their implementation.
Here that is written with company Lenovo:
