800Mhz A1G3XE the best choice than the 800Mhz A1G4XE?

According to benchmarks by Motorola, the 7451 is substantially faster than the 750FX at the same clockspeed.

I can't subscribe to this point of view.

I think it is far more likely that the architectural improvements of the 750FX simply do not show up in the results of the SPEC 95 benchmarks.

If you take a look at the G4+ architecture, you'll find that Motorola has made a lot of improvements compared to the original G4 design.
