I have seen many peoples castigating the Prescott compared to
the Northwood P4. We had a stretch of rainy days, so I tested
some old PCs - I had a draw full of Pentium IVs to swap in them.
One benchmark for L1 latency came out thus:
Northwood 2 cycles
Prescott 5 cycles
Cedar Mill 4 cycles
How did Intel bugger up the L1 cache?
