In The End

Nothing beats compiler optimizations because a good compiler, like Intel’s compiler for Pentium chips, will order processing logic in such a way to make the most effective use of the architecture of the chip. This is why programs optimized for the P4 always perform so much better in benchmarks against AMD, and vice-versa. All else being equal though, the L3 cache in the Pentium 4 Extreme Edition is a welcome boost to the processor family, and will be of good use in certain applications due to the fundamentals described herein. Will it be enough to stave off the Athlon 64 FX while Prescott is being readied? Even our friend the branch predictor can’t tell you the answer to that one…only time will tell if Intel will regain the performance crown!
