+Not only. On lots of hw the rop caches can be faster/async. That said 10/15x is a lot, way too much. Something is wrong in the setup.

+
+Yup - so much that my brain interpreted as %, not x! Seems like it was a shader compiler issue not compiling much of the code to actually execute for the PS:

+Could be, but with linear order and linear layour cs should have coalesced writes and no obvious problems. I assume buffer swizzling is uncommon. Also PS usage for buffer should have one more hidden cs run for layout change, unless there was memory aliasing.

+
+**@MissQuickstep**
+
+Shouldn't make a big difference in practice.  A compute shader has spatial grouping where most waves/warps will sample adjacent memory and hit relatively high bandwidth and cache utilization even in the naive implementations. 
+
+No way 512x512 is BW/cache bound, though
+
+**3/** **@NOTimothyLottes** ^1682136826553745408
+
+**@vassvik** **@MissQuickstep**
+
+You can look at what I did for CAS/FSR1/etc: Simplified {64,1,1} to {8x8} lane remapping (so 4x1 lanes map to a 2x2), semi-persistent waves to avoid wait on store complete for wave relaunch and get better L0$2work mapping, etc. Have to make sure DCC matches (PS vs CS paths). Etc.
