Yes, some details were left out of CPU performance increases. The same was done for memory performance increases though. We have been discussing memory bandwidth as memory performance, completely leaving out memory latency, which has also improved tremendously. -Raystonn _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
