    GPU L2 cache size of A10-7870K APU

    magnolia

      Hi. I'm a student studying the architecture and characteristics of GPU caches.

       

      I have A10-7870K desktop APU for my testing platform. I want to know the L2 cache size of the APU for my GPU L2 cache flush experiment.

      I found that "clinfo" does not show the GPU L2 cache size.

      I found the GPU L2 cache size of A10-7850K APU is 512KB. ( What is the Size of GPU L2 cache for A10-7850k APU?)

      Other documents and web sites about GCN architecture and A10-7870K seem to have no information about the exact GPU L2 cache size of the A10-7870K model.

      A10-7870K with Radeon™ R7 Series  )

      I wonder where to find that kind of information...

       

      I'd greatly appreciate it if anybody could help me!
