Tenchusatsu: RE: CAS Latency

This reply was meant to put the KX133 performance in the right perspective. I think they didn't do a bad job.

One thing which Intel did right was forcing the DRAM industry to better parameters like the CAS latency which went from 3 to 2 (RAS to CAS latency and Refresh went from 3 to 2 as well)

Tom Pabst benchmarks show an about equal improvement in going from PC100,CL2 to PC133,CL3 as in the step from PC133,CL3 to PC133,CL2.

But, The AGP bus with it's highly pipelined transfers doesn't care about CAS latencies and some of the performance improvements found for PC133,CL3 are the result from improved AGP performance.

The intention of this reply was to show that the KX133 is a good chipset. Differences and improvements stay small.
Maybe just enough to make the Athlon+K133 to be a better performer than the PIII+i840. :^)

Hans.
