GamePC – Battle at 90nm : Power Consumption and Performance Compared
Our Doom3 benchmarks show the “Winchester” Athlon64 in a more positive
light, besting the “Dothan” Pentium-M by an advantage of about a single
processor speed grade. The opposite is seen in Far Cry, where the
Pentium-M bests the Athlon64 in terms of performance per clock speed.
This is a slightly different benchmark in that it shows that a 2.0GHz Dothan is faster than a 2.2GHZ Athlong 64. Go figure.
