GPU L2 cache size of A10-7870K APU

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!

As I know, GPU L2 cache size of A10-7870K is 512KB which is same as  A10-7850K. Actually, both the models have very similar specs, however A10-7870K provides better performance due to its higher cpu and gpu clock speed.
