Early PowerMac G5 1.6GHz Benchmarks

Aug 24, 2003 Update: Xbench 1.1 is now available and is optimized for the PowerMac G5.

Again, XBench results seem to vary widely each time it is run on the same machine. The main improvements on the PowerMac G5 with Xbench 1.1 are in the Memory tests. The best results available are provided.

XBench 1.1 vs. 1.0, PowerMac G5 1.6GHz

Comparison Numbers: XBench Comparison Site - note: scores from the same computer vary widely.

Benchmark results from Jim Haw.

Aug 22, 2003 Update: Posted to xlr8yourmac.com, from the author of Xbench:

Xbench 1.0 uses the vec_dst instruction, in the altivec test, and the memory stream tests, which causes a big performance hit on the G5. I talked to some Apple engineers at WWDC about the issue and am working on a 1.1 release that avoids using vec_dst when running on the G5. The new release should be out real soon.

Aug 20, 2003:

Some early benchmark numbers provided by David Marcus and James F. Haw (Thanks!).

These are benchmarks of Cinebench 2003 and XBench on a Single Processor 1.6GHz PowerMac G5.

Usual benchmark caveats apply -- including some extra ones.

1) Benchmarks don't necessarily reflect real life performance
2) These benchmark applications are not G5 aware. So, they may incur a performance hit if they use some outdated commands. (see PowerPC G5 Performance Primer)
3) Real-world applications with G5 optimizations are probably a better benchmark... but we don't have those yet.
