Dual processor - Dual Core + max

[tommyjj]

hello folks,

 

I'm just about to buy a new workstation... zzzzzzzzzzzzzzzzzzzz i know. I wont bore anyone with the specifics though.

 

I was just wondering whether the 3ds max + Vray combination that i use can render with any more than 4 buckets? i.e. can it utilise any more than 4 processors?

 

At the moment I use a dual 3.2ghz xeon system, with hyperthreading turned ON. So Vray (and task manager etc) sees 4 processors.

 

If i buy a dual core - dual processor system, and turn the hyprethreading on, will Vray, max etc see 8 processors? If it cant then I struggle to see the benefits of dual core, dual processor systems.

 

cheers

a true dual core cpu will dramatically out perform a single core hyperthreaded CPU even tho Vray and task manager will both indicate 2 processors available.

 

hyperthreading isn't actually 2 cores its tricking windows.........dual core CPU are actually 2 CPUs

[tommyjj]

I realise that hyprethreading isnt actually creating two cpus... however, I've noticed a pretty significant speed boost by turning HT on.

 

I was really asking whether Vray and max could take maximum advantage of a dual core, dual processor system with the HT turned on... as in... can it use all 4 logical, and 4 virtual processors. Or would you have to leave it with HT off?

[JamesTaylor]

yes it can, however the best (reasonable priced) dual core procs are the AMD versions which don't support hyperthreading. i believe that intel do a dual core CPU that has hyperthreading but i know it used to be very expensive in relation to the AMD's and i have no idea if it was actually any faster etc.

 

I think Vray can support upto 10 buckets per render, these can be obtained via a multiproc setup or thro DR.

if your looking for speed, i'd do some research along the line of this thread http://www.cgarchitect.com/vb/17696-new-intel-conroe-vs-new-xeon-5100-series.html looks interesting to me from 1st glance!..........its a pain in the arse how quickly all this stuff moves!!

why not wait for the Conroe from intel? based from all the tests, the Conroe totally wiped every processor out there. Expect a 30-50% drop in single core chips.

 

as far as i know the Conroe should be out in 2-3 months or so

If you wait for the next gen, when you get it it won't be the next gen anymore It's a losing battle. Buy the hardware when you need it.

agreed! ... and enjoy the price cuts of the stuff already out there because of that "next gen" stuff

 

conroe is supposed to be out this month... dunno where it is though:confused: :confused:

Vray DR supports 10 machines, not just 10 buckets. For backburner its unlimited.

[AJLynn]

You don't even need DR. However many (real or virtual) CPUs you have, you can use them, until system memory becomes the limiting factor.
