Vince Paske Posted November 1, 2007 Share Posted November 1, 2007 Has anyone compared 2 systems with identical hardware, one using an all 32 bit software, the other 64 bit software? I'm interested in Max 2008/VRay results. I'm curious to know if rendering speed increases with the 64 bit version, for instance with a scene that doesn't necessarily take advantage of the larger memory available of the a 64 bit system.

manta Posted November 1, 2007 Share Posted November 1, 2007 its probably not going to be more than 10% faster...64bit doesn't really have anything to do with speed... Link to comment Share on other sites More sharing options...
carlangas Posted November 1, 2007 Share Posted November 1, 2007 its probably not going to be more than 10% faster...64bit doesn't really have anything to do with speed... I've heard that cpus designed for 64 bit operations would run more efficiently in a 64 bit environment and therefore run a little faster.... is this not true? im no expert at this Link to comment Share on other sites More sharing options...
Nic H Posted November 1, 2007 Share Posted November 1, 2007 The main difference I have found is being able to render bigger scenes/images and it is alot more stable with large amounts of geometry. Thats using Max 9 and Vray 1.5 64bit. Apart from that I cant tell the difference. Link to comment Share on other sites More sharing options...
vasendak Posted November 1, 2007 Share Posted November 1, 2007 hi there... is my first post... well, faster faster awesome faster nope... but faster 30% in some picture that remains 2h? well that half hour can help you isn`t it? but you have to do some little things... let see... at least your OS must be 64 bit, max 64 bit and vray 64 bit... after that remember at least your 4 gb in ram... more better... now if you think in cash well... 30% against some extra bucks? well is your decission... i try the same render in 32 bit pure (that means 2 gb top not the 3gb emulation guys)... against 64 bit pure (no emulation or overclockin`) and there be some extra time for me and like it.... but 2008 is almost same 9 isn`t it? well is your choice... regards, Link to comment Share on other sites More sharing options...
AJLynn Posted November 1, 2007 Share Posted November 1, 2007 I ran that test comparing mental ray FG rendering in Max9. Not a complex enough scene to require 64-bit memory handling. No speed difference - I did it a few times and sometimes 32 bit was faster, sometimes 64 was, but always within a couple percent. Now, in Cinebench I did find a difference of several percent.

jvlive Posted November 2, 2007 Share Posted November 2, 2007 Wow. All this time I thought it would be a significant difference. Link to comment Share on other sites More sharing options...
CRD Posted November 2, 2007 Share Posted November 2, 2007 On smaller scenes that stay under 2GB or so, there was no difference. I don't have the numbers, but we did some tests while converting our compters from XP32 to XP64. What we have found is that now we can send HD animations with millions of polys, particles, displacement, etc and watch the RAM usage jump to 8 or 9 gigs and still render fine. 64bit is not making your processors any faster, just allowing you to handle larger, more complex scenes without crashing, which is a huge bonus in my book.

Hazdaz Posted November 11, 2007 Share Posted November 11, 2007 What I don't get is that the CPU companies (especially AMD since they were way ahead in the 64 game) were "promising" a certain amount of speed increase due to running in a native 64-bit environment (when everything from the OS, to drivers to the apps where 64 bits)... so why aren't we seeing a token speed increase (even something as small as 5 or 10%)? Is it cuz of the 64-bit Windows overhead? Link to comment Share on other sites More sharing options...
WestCAD Posted November 12, 2007 Share Posted November 12, 2007 just picked up a quad Q6600 with Vista64, and it may be wishful thinking but Maxwell renders usable files in 1 hour, and AutoCAD Architecture seems to load and perform much faster than my previous conroe e6600 with xp32 Link to comment Share on other sites More sharing options...
dagor Posted November 12, 2007 Share Posted November 12, 2007 it`s because you system use RAM and not swap file on HDD. ram always faster than HDD Link to comment Share on other sites More sharing options...
