    Interesting question about the L1 texture cache size of G200 used in David's review

    Why 8K per SM Why 8K per SM, cut them on low end GPU of the same series? Based on my measurement, it seems G80 and G200 both use 20K per TPC. There's no L2 cache on low end card like 8500GT. Fix me if i'm wrong.

    Interesting question about the L1 texture cache size of G200 used in David's review

    It's TPC Based on the the diagram draw by David, The 8K L1 texture cache is exactly below the SM controller, the SM controller is accept request from SM[0] SM[1] and SM[2]. So the 8K is shared by 3 SM and won't be 24K. I raise the question because 8K for each cluster is reasonable. But the...

    Interesting question about the L1 texture cache size of G200 used in David's review

    David mentioned the L1 texture cache size is 8K for one TCP. so the total L1 on the chip should be 8K * 8 on G80 or 8K * 10 on G200. Ok. If the L1 is private, usually be true on CPU side. So the max L1 size which could be accessed by single pixel shading thread is 8K. So I use the pointer...
