post #1 of 37
Thread Starter 
i know its an highly debated question...but let me ask you guys....
will i get any bonus if i move over to 64bit os for benching? even with 2gb of ram?
give me suggestion guys

64 bit OS will actually slow you down by a couple % overall performance if you're under the 4GB limit. I'd stick with 32 bit until you have 4GB (RAM+video card RAM+ALL Cache on your machine CPU, drive cache, etc...)

um no

64 bit is not just to utilize more ram. Its an entirely different os thats why 32 bit drivers don't work with 64 bit. I'm not googling it but you obviously don't know what you're talking about

You're misunderstanding me somewhat. I know there's more to it than address space. I told him to stick with 32 bit because his memory is below 4GB. That way, it keeps things nice and simple.

A 64 bit OS takes on average 1-3% longer to load because of how it handles things differently. So, if you don't need the 64 bit compatibility, or you don't need the extra address space for memory, why move to 64 bit at this time? It's just extra overhead that's not necessary imo. Especially for benchmarking which is what this thread is about.

I've seen a several articles (I think one was on Tomshardware.com, but don't remember) about this very issue. On the same machine, with the exact same hardware it was noted that there was a 1-3% load time increase on the OS, as well as several programs at the time. If memory serves me correctly, they were using some flavor of Windows 7 to do the comparison.

and so today we learn why a lot of today's LN2 benchers actually use x64 versions of windows 7 for 3d benching

I use win 7 x64 and XP x32. Have noticed zero difference, and actually a little gain in 7 x64 over XP in some benches. So it really depends on what bench you are running. there is no definitive answer out there so i dont know why you decided to limit it to one...

+1

Though HDTune is slightly slower in win 7 x64 pro compared to XP x86

Who cares about benchmark scores?

^i do......and maybe half of the guys in OCN oc team in hwbot do......
coming back on track.....is the notion that 2d bench apps run faster on 64bit os's is true?
@Ftw...any comment?

This thread is about which OS for benching, maybe anyone reading it?

I pretty much stick to win 7 x64 for most 3d benching & XP x86 for 2d benching, although there are a couple 3d that do better in x32 & 2d that do better in x64. You really have to try things & see where you get the best scores.
