only info i could find so far

・Dhrystone v2.1
PS3 Cell 3.2GHz: 1879.630
PowerPC G4 1.25GHz: 2202.600
PentiumIII 866MHz: 1124.311
Pentium4 2.0AGHz: 1694.717
Pentium4 3.2GHz: 3258.068

・Linpack 100x100 Benchmark In C/C++ (Rolled Double Precision)
PS3 Cell 3.2GHz: 315.71
PentiumIII 866MHz: 313.05
Pentium4 2.0AGHz: 683.91
Pentium4 3.2GHz: 770.66
Athlon64 X2 4400+ (2.2GHz): 781.58

・Linpack 100x100 Benchmark In C/C++ (Rolled Single Precision)
PS3 Cell 3.2GHz: 312.64
PentiumIII 866MHz: 198.7
Pentium4 2.0AGHz: 82.57
Pentium4 3.2GHz: 276.14
Athlon64 X2 4400+ (2.2GHz): 538.05


These benchmarks on done on just the PPE (no spes to my knowledge) The cell ppe performs at pretty much 1.8GHZ The biggest reason for this is that its in order execution. Out of order execution it would actually perform like 3.2GHZ. Its the same deal for the 360 cpu since its also in order execution.

Looks about right to me.
These Cell processors are good for a very few limited specific tasks..

They're good when the software knows how and can use it....

Unfortunatelly there is no way to benchmark "Fun-ness".

The Wii is the best console as far as fun!
