Performance Expectations

Ad

Well given the 90-95% hit rate of the super bypass feature and the touted 25% reduction in memory latency I would guess that we should see a pretty reasonable gain in performance across the board. I expected to see about a 3% - 5% gain through out our test suite. Obviously, memory intensive applications should receive the most benefit. Another reason I expected to see a pretty good gain is due to the fact that one of the Athlon's platforms biggest bottlenecks is its memory bus. While the CPU is cruising with a whopping 200MHz front side bus (1.6GB/sec) the memory is slowly moving at 100MHz (800MB/s). Any increase to the platforms memory performance should have a big impact.
