Hi there, has anyone got some expirience with quad processors. is there a great advantage or just marginal? i was told (by a salesman)that one bloke did a 7 hour render job in 2 hrs sound to good to be true. love to get some comments thanks robert.

I can say I've seen great improvements just by having a Dual Core processor. Of course, the video memory upgrade also helped heaps. If the Dual Core improved this much (rendering a Revit model and a Maya model at once while working with another Revit model with minimal slowdown and Faster than normal render times), then I can only imagine the performance gains from a Quad Core.

You fell victim to one of the classic blunders. The most famous is never get involved in a land war in asia, but only slightly less well known is this! Never go in against a Sicilian when death is on the line! |

you should get performance gain in Revit when doing rendering, because Accurender will take advantage of the multi-processors. Revit will not at this time. but i'm sure the new 64-bit version of Revit/Vista will and should start pushing this program to heights/functions that are mind blowing. HTH

Its not too good to be true, I just had some high end walkthroughs renderings and isometric renderings that took no time at all to do. Normaly would be a good 7 hours and took consideralbly less time, but then again we were running dual quads so a total of 8, but still double the hour or so it took us, and that would seem about right. So even though i havent seen what a single quad can do, dual quads can fly so my assuption is that one is still a ton better than a single core.

thank you gentlemen for such a quick responce, i failed to mention that i personally do not do any 3d photorealistic rendering most of my 3d stuff is in shaded mode but with a lot of detail (i do lot of large shop interiors) my file sizes are up to 150 MB i had a lot of crashes since 9.1. 2008 did not improve that much in my case i am trying to improve on evrything. currently i have got a dual core with 4 meg of ram. (the 4 GB of rem appears to be a contentious item as windows xp only will use 3 GB i was told) so would quad core really be the go under these circumstances? cheers, robert melbourne

Other than for rendering there would be no real advantage to having a quad core over a dual core. The dual cores are still a ton cheaper and you probably wont have any major leaps from one to the other untill revit is a multi core program, which it isnt right now. One thing you might consider is that you may not have switched your computer to 3gb, you need to change the boot.ini so it will boot 3gb even if you have 4 gb...if you have 4gb you can read 3.5 gigs with XP. So under thoes circumstances, save your money on the quad right now, and get up to 4 gb and put the 3 gig switch on your OS and maybe go for a dual core, but quad is excessive since 2 cores will viturally be unused. Crashing in 9.1 was a large problem due to over detailing, the failure to purge files, as well as mismanage of worksets. We used to have a lot of issus with crashing as well, but with thoes projects that did we had major flaws in how we ran and managed thoes three.

thanks bronco, some one else confirmed what you said about the switch and the quad core. setting the switch may solve an other prob i have with my old machine. after turning it on, the screen dies ( it is not the monitor, it does it with others monitors as well). but it still runs and i have to press the reset button. now i can spend the money responcible on a good bottle of aussie red cheers. robert.
