I'm sure you're not forgetting that the K6-2 L2 runs at 100 Mhz, while the K6-3 L2 will run at 350 and 400 Mhz. Does half the cache size and four times the speed translate into 10-15% better performance? Pravin, I don't think it does. It comes back to the old latency vs. bandwidth argument. Moving the L2 onboard does not decrease the critical latency enough to account for a 50% performance improvement. If a benchmark was bandwidth limited from the cache (can't think of any of those right now), then you might see larger performance gains. Scumbria
