MacNN reader Derek Kent writes: "NASA recently benchmarked Apple's dual 2GHz Power Mac G5 at its Langley Research Center in Virginia. The main purpose of the tests was to compare the G5 to the G4 for 'computational fluid dynamics
applications" however they also compare it to the Pentium 4. The test was well documented and concludes that "the G5 has about 22% better scalar floating point performance per clock cycle than the G4 systems tested and 32% better floating point performance per clock cycle than the P4 systems tested.' Even more interesting is that NASA's benchmarks come close to mirroring Apple/Veritest's results for SPECfp_rate_base2000. Apple's benchmark lists the dual 2GHz G5 as having a 194.5% performance advantage over a 3GHz Pentium 4."

NASA doing benchmarks? That's a first...

This f***ing rocks! Optimized this should catch up and surpass the 3.2ghz P4 with a single proc.

Seriously though, using "NASA" and the phrase "Not a very scientific test" in the same sentence is laughable, man. C'mon.

In reality, the 2Ghz G5 was on par with the P4 (2Ghz+32%=2.64GHz). A 3.0Ghz P4 would be indeed faster than the top G5 when it came down to single processor operations. In any case, the G5 is the top dog to beat as MAcOS X uses intensively a second processor (a minimum of 40%). Therefore a dual 2GHz G5 will be equivalent to a 3.7GHz P4 (as a minimum), that is without any special optimizations and with apps that do no use heavily a second processor.
When Panther comes out, the gains will be even more dramatic. Stay tunes folks!
