MacAddict’s Dual G5 Benchmarks

Mac Addict published some very interesting benchmarks using PSBench 7 on a dual 2 Ghz G5. The dual G5 was compared to a 1.8Ghz G5 and to dual 1.42Ghz and 1.25 Ghz G4’s. While the dual G5 was faster, using 512MB RAM, it was not that much faster than the single 1.8. For instance, the best case was in the “Convert from RGB to CMYK” test where the dual G5 performed the test in approximately 15 seconds and the 1.8 G5 performed it in 21. However, in the “Rotate 90 Degrees” test the dual G5 took 24 seconds while the single 1.8 took 25. In several other tests, the results were or almost were on the same scale.

Not until they loaded the dual G5 with 2GB of RAM, that is! The G5 had been shipped from Apple with 2 GB of RAM they removed to match the systems up at 512MB. When they loaded 2GB of RAM back in, the dual G5 performed the “rotate 90” test in 2.15 seconds! The “Convert from RGB to CMYK” test was performed in approximately 7. They not only prove that the PSBench test and Photoshop love memory but also show that the strength of the G5 lies in its memory and bus architecture. Applications that can take advantage of those will scream on the dual 2GHz G5's and the future, even faster processors to come.
