“We have compared the new G5 DualCore 2.0GHz and 2.3GHz with a old watercooled G5 dual 2.5GHz. The dual 2.5GHz was equipped with a GeForce 6800 Ultra graphics card, not standard equipment. The DualCore 2.0 had a two-drive RAID-0 volume so the disk test is better than normal,” Mats Björnström reports for 99Mac.
“The Power Macintosh G5 is better than ever and this is likely the last major update that we will see before the transition to Intel- processors. Apple has polished the details and the new processors gives some extra power. Because the exterior is largely [unchanged] this feels more like a “speedbump” even if the processor-switch is more significant than that,” Björnström reports. “Performance-wise, one Dual Core processor doesn’t make for a large difference compared to two old G5 processors. We predict that the new Quad 2.5GHz Powermac will make for a performance increase of 70% or more.”
