TWO CPU vs ONE CPU
hi,
I just purchased daVinci resolve and i need to buy MAC PRO.
I have 2 options;
Option 1 (used-2008): TWO 2.8Ghz quad core (Nehalem processor)
Option 2 (new-2010) : ONE 2.8Ghz Quad core (Intel Xeon procesor)
both are the same price;
all optins are the same (ram, cards etc)which one should i buy for better daVinci performance..
firts option has 2CPU but old processor and the second one is newer but single CPUregards

2008 8 core Mac Pro is now certified (with 8bit video output enabled)
The 4 core 2010 model is not certified. From what we hear it generally isn’t fast enough to decode and do realtime quality. -
hi Vladimir
what does 8bit video output enabled? does it mean better MAC pros has 10 bit or better option?
do you think that older 2CPU is faster than newer single CPU version?

I think the quad 2010 2.66 nehalem is a certified machine so I would think that the quad 2.8 2010 would be. There are refurb mac pro’s on the apple store right now and if you get a dual cpu you could eventually switch out the cpu’s for faster units, if you are careful.

Basically the problem, as I understand it, is there are multiple measures of performance in these systems.
For example, the limiting factor on a 2008 Mac Pro is bus speed (if i remember correctly) which makes it difficult to pipe enough data through an otherwise strong processor.
The limiting factor on a quad core 2010 is processor speed and number of cores, which really hurts performance when working with compressed codecs (ProRes, RED, etc). You *may* be able to get away with it with DPXs, but no quad core computer is officially certified.
What BM did to enable support for 2008 Mac Pros is enable an extra 8 bit monitoring mode, which means that the image prepared for monitor output is smaller in size and detail, reducing bandwith, allowing the 2008 8-core mac pro to work in realtime. 10 bit monitoring option is always available, but in my experience it drops performance down to 22 frames or so.
I would honestly say that you should try and swing it for the 8 core 2010 model, or an 8 core 2009 model. Yes it’s a bit more money but your system will be *solid* with no caveats.
