aks93,
I presume you're not going to run your 1.6A at stock, but rather at 2400MHz, and 2550-2650MHz if you can, as others on this board are doing.
Yes, Tomshardware did a comprehensive benchmark comparison a few weeks ago...He clocked a P4 at 2300MHz, 2400MHz, 2600MHz, and 3000MHz...and compared it to all the Athlons, plus an Athlon XP 2000+ overclocked to 2200+ and 2300+ with watercooling. For the tests, the Athlon 2300+ used a 155MHz FSB, the 2200+ used 150MHz FSB, and the 2000+ used 133MHz FSB, compared to 118MHz base FSB for the P4 2600. The P4 is bandwidth limited (its crippled at 118MHz FSB), so obviously it would have performed better with higher clocked DDR or RDRAM. A few sample results:
Sandra CPU Bench: P4 2600 beats Athlon XP 2000+ by 38%, beats XP 2200+ by 28%, and XP 2300+ by 24%
Quake 3 Arena: P4 2600 beats Athlon XP 2000+ by 33%, beats XP 2200+ by 25%, and XP 2300+ by 21%
MP3 encoding: P4 2600 beats Athlon XP 2000+ by 20%, beats XP 2200+ by 11.26%, and XP 2300+ by 8%
MPEG4 DIVX encoding: P4 2600 beats Athlon XP 2000+ by 18%, beats XP 2200+ by 9%, and XP 2300+ by 6%
