För alla er som betvivlade Apples tester kan nu se ett mer oberoende test återspeglas på Creativemac's site. Här har man i ett antal ronder kört en ny PowerMac G5 Quad mot dels den äldre Dual 2.0 G5:a samt ett par vassare PC-maskiner. Summeringen? Har nedan saxat ett par kommentarer:

In the first test, the G5 Quad rendered the scene in 40 percent the time it took the dual G5 system; in the third test, the Quad took 45 percent the time the dual G5 took; and in the fourth test, we saw a three-fold improvement in performance, with the Quad coming in at about 32 percent the render time that was experienced on the dual 2.0 GHz system
That's impressive, to say the least. You never expect to see that kind of improvement just by slapping more CPUs into a system. At least I didn't. A hundred thirty-three minutes versus 43 minutes? Come on. If you use LightWave on the Mac, there shouldn't be any question about purchasing the G5 Quad.

Test 3 (in photoshop CS2) included the application of every single filter that ships with Photoshop CS2, with the exception of Displace, which involves an external displacement map that I didn't want to have to deal with across multiple systems. It also included a few transformations, text manipulation, selections and fills. Again, the G5 Quad performed remarkably, giving us a 1.6x speedup over the dual 2.0 GHz G5 and a 1.7x speedup over the dual 3.6 GHz Xeon system. It was beaten, however, by the Alienware quad-processor 2.21 GHz Opteron system

…as you can see, in After Effects, the G5 Quad beat the fastest PC system in the universe (at the moment) in two tests (the last one quite handily, I might add). But it was beaten in four others (with one tie)

Bra drag i maskinen hur som helst
