End user tests Conroe @ 2.4ghz vs Athlon 64 @ 2.8Ghz, result: Conroe not as fast?
Now, for the very first time, someone actually got hold of a Conroe chip in their own lab and did some tests. It was a 2.4GHZ Conroe (Link: CPU-Z) against an Athlon 64 overclocked to 2.8GHZ. The overclocked Athlon 64 had a 2.8/2.4 -1 = 16.7% clockspeed advantage.
The following results were obtained by running 32 bit ScienceMark binaries optimized for Intel Pentium
