How much power required to grade a 4K project ?

[Paul Provost]

look out for the RED 4k laser projector…
yes the Linux system can be built out to handle this.
Also the upcoming Resolve Windows may have the scalability needed for stereo 4K full realtime.
better wait for Q1 2012.

BUT, can resolve currently monitor out 4K? I don’t think so…
right? 2K is high as it goes for monitor out?

Paul:
Redlaser projector is not even announced at all , i am not sure that will be released soon (i have the feeling is like REDRAY), unless november the 3rd will be about that as well

currently , without the deckling 4K , no 4K out of resolve ..

I am wondering how many GPUs is needed for a 4K project , as i said i have 3 and still not enough …

I guess that in widows having 7PCIe @ 16x speed , would be possible to have like 2 Cubix Desktop 4 to have 8 GPUs….

thanks

I think red 4k projector is already in prototype
I’m not sure even with decklink 4k card, resolve can monito 4k. will need to be upgraded to have 4k monitoring capability
I think it’s more than just quantity of gpu. It is the speed of the connection to the gpu
Mac has no infiniband type protocol, so it is stuck with pcie expansion which is limited in bandwidth

Prototype doesn’t mean product. Especially when Red is the company. I don’t expect to see working product for at least 2 years. I could be wrong, but if I am, it’s probably because my estimate is too optimistic.

It sure seems like Bus bandwidth on the Mac-Pro is the bottleneck to doing 4K work. The External expander boxes have only one PCIe 16x slot to share amongst all of those cards. And having at least a x8 PCI bus for a SAS array would be a must I think.

I would think an Asus P6T7 Supercomputer with 7x 16x slots could do the lifting required wiha a fast disk array.

Then it is just getting the Decklink 4K to work with resolve…

So not even resolve on linux today have a 4K monitor out ?

Hi Everyone,

The answer to the dual Xpander Desktop 4 is a qualified “yes”. Most motherboard configurations running Windows XP or Win 7, or Linux, should be able to run a dual Desktop 4 configuration just fine. Keep in mind that a dual desktop 4 = a Rackmount 8.
