Some of you might know me…i have posted most of my work here and have gotten feedbacks from all of you. As some of you know i am using a Dual Xeon 3.06 with 1Mb cache and 2 Gb ram. Recently i bought a new machine Xeon 3.06 but 800 instead of 533…even with the new board and ram and cpu…my dual opteron 244 beat the hell of my new xeon’s…xeon was 2:24 while amd was 2minute 16seconds.
my configuration…AMD Opteron…win XP 64bit…2gb DDR 333 ram.
8 seconds isn’t exactly beating the hell out of anything. I’ve heard the that xeons really outperform when there is more blurry reflection in the scene & stuff like that, but I forget where I got that from.
But I have noticed something that dissapointed me though. Since I’ve been using vray, I’ve been rendering on a dual athlon mp 2100+. The total clock speed comes out to about 3.4 ghz. I just upgraded to a dual 3.06 xeon w/ 533fsb. That comes out to just a little more than 6ghz. So I was really expecting to see my rendering speeds nearly double with the new machine. I tried a somewhat low res. rendering without any reflections and the time difference was less than impressive. I mean, clearly faster, but nowhere near twice as fast, like I thought it would be. Haven’t tested on more complex scenes though.
A scene that only takes 2:24 to render is hardly a good benchmark for either machine.
Try a scene that takes an hour or more preferably, with a lot glossy reflections, glass and high resolution maps. You know, a normal scene we deal with every day. I bet the xeon wins by a lot more than 8 seconds.
I have access to both types as well, and the zeon always wins on normal scenes. This of course, is only my finding and certainly may differ from yours.
Oh, I’m not trying to bash AMD, they are a great product. I have two in my farm.
My office recently bought 6 dual opteron, 3gb rams workstations with winXP. And I always feel like they could run faster (well, I always felt like that when new computers are around ;).
You guys mentioned winXP 64bit. Where did you bought that? I just heared from a 64bit version that HP provides. But I’m not really good informed about that…
WinXP 64bit now in beta stage, you can download it from MS site for free.
They promised to release it spring 2005.
All i can say is that Povray, optimized for Athlon64, tested on 64bit linux was 30% faster then it’s 32bit version. As i remember, 32bit time was 1800sec, and 64bit - 1200sec.
