PowerMac G5 Benchmarks (again)

For those still following the G5 Benchmark discussions... Luxology posted some details surrounding their demo and their belief that this represented an accurate methodology in comparing systems:

The demo set up itself was designed to require a large number of computes and to push a large amount of data in and out of the chip to show both processor speed and bandwidth. I believe the demo accomplished this in an effective and very fair manner.

Meanwhile, xlr8yourmac.com posts a user submitted reference of a Java Linpack Benchmark. This user notes that the Dual G4 1.42 achieves 90Mflop/s, while the new Dual 2GHz G5 scores 236Mflop/s. While other systems references are given, the benchmark also tests the specific java implementation along with processor speeds... so comparisons across platforms is not necessarily representative.

Users are reminded that all user-provided benchmarks of PowerMac G5's have been done in uncontrolled situations with pre-production machines with non-ideal code.

Macuarium.com (Spanish) posts photos and a first hand account with a PowerMac G5.
