Title: Performance graphs
Post by: Raistmer on 23 Jun 2011, 04:34:05 pm

I updated performance graphs for my hosts with new app revisions and different params sets.
Here they are:

I was wondering about the first graph the 16/4096/2048 is that an unroll of 16?

I updated my HD6950 host to Catalyst 11.6. And observe huge (!) performance drop  :-\
Not a lot data collected (because all so slow!), but...
here plot for AP:

For MultiBeam app situation even worse - both CPU and Elapsed times increased.

EDIT: I did few more AP tasks now and see some correlation: If CPU time lower than with 11.2 - Elapsed time greatly increased. But there were tasks with same values as for 11.2...

Here is the comparison (on the same hardware and driver) for last few ATi MB revisions.
As one can see, rev365 offers much improved performance than prev V7 builds and it's speed with V7 tasks approaches to speed of V6 processing.
