OK folks, I went into Micro Center (which finally has a G5 1.6 Ghz tower on display) and did some 3D Renders of a Bryce 5 still image. Over the past 4 months, I've rendered the exact same image on a number of PC systems and G4 systems as well. I have all the render times written down and documented. Although Bryce 5 is not a high-end 3D app., it's still a pretty good indicator of Raw CPU speed with NO optimizations for any specific CPU (PC or Mac). So, here is a comparison of the G5 1.6 Ghz compared to other systems rendering the same Bryce 5 image: G5 1.6 Ghz -- 1:21 2.66 Ghz Pentium 4 -- 1:22 2.8 Ghz Pentium 4 -- 1:13 3.06 Ghz Pentium 4 -- 1:11 Athlon XP 2400+ -- 1:09 1 Ghz G4 (single) -- 2:27 Dual 1.25 G4 (1 processor used) -- 1:58 Dual 1.42 G4 (1 processor used) -- 1:43 It will be interesting to time the 1.8 and Dual 2.0 as well when those units become available. So far, the G5 it is not quite as fast as I thought they would be, although an improvement over the G4 for sure. However, the G5 1.6 Ghz was only 22 seconds faster than a single G4 1.42 on the render test. The Athlon XP 2400+ processor seems to kick some butt on all of the processors tested so far (haven't had a chance to test faster Athlons at this time). Well, any comments or observations on this people ??
