AMD A10-5800K APU Speeds aren't correct.

ZombieCake · Nov 17, 2013

Hey,

I recently built my own PC, I have an AMD A10-5800K APU with the integrated AMD Radeon HD 7660D.

I checked online and via GPU-Z, it should be getting ~30GB/s and the memory should be around 1000 MHz.

Here's my problem.

My Bandwidth on it is 22.4GB/s and the Memory is 700MHz. The Bus Width is correct at 128.

I've got 8GB (2x4GB) of RAM at ~1600MHz.

I'm not sure what my problem is, any suggestions/tips?

I don't have a lot of experience with the AMD APUs, but the references I can find list the GPU core frequency (it has no memory, it uses your RAM) is 800Mhz. It may be reading an idle frequency maybe? and it hits higher frequency's at load?

As far as the bandwidth speeds, that will depend a lot on the speed of your RAM, most of the spec lists that I've seen were tested with 1866mhz RAM, and mostly the consensus is that 2133Mhz RAM is the best to go for with the integrated graphics since they don't get to benefit from the much faster DDR5 memory in most dedicated graphics cards. The slower speed of your RAM may be affecting the throughput of your system.
