To echo Matt, it definitely involes some adjustments to the farm! That may even be a stumbling block for some, or at least a weird surprise. There's a temptation to think that all you have to do is put a GPU in your render node and you're golden. Well... that may or may not be true... depends on all kinds of things. It could be that easy, but it could also require new hardware entirely. It really depends on what kind of GPU machines you're wanting to implement, what kind of scale you're going for. There is no standard way of dealing with this, not yet at any rate. It's just too early in the life of GPU rendering. We've found that for us, it's been worth it to devote some time and money to outfit a portion of our farm for Redshift. Our stuff just looks that much better in less time. When we saw what it could do for us, it was a no-brainer to investigate our hardware a little more seriously.

Again, all relative to what you're doing...

We still have racks though.... nothing wrong with a GPU in a rack....

Yeah it would involve quite an adjustment for a trad farm - rackmounts would be a little useless. I also don't think RS is quite gunning for the arnold market, its aiming for the smaller shops who don't have massive render farms.

I rendered 10 million hairs on a character today, ended up using 20Gb of system ram, as the gpu was only a quadro k4000, but it rendered pretty fast still. The extraction was the longest part.

Also, just as a quick test, I've instanced 5000 trees using ice scatter, each tree has 1.2 million polys, so that makes it 6 Billion(?), used 6 Gb system ram. render stats below:

# INFO : [Redshift] Rendering frame 0
# INFO : [Redshift] Scene extraction time: 4.623 s
# INFO : [Redshift] Rendering time: 176.518 s (2 GPU(s) used)

just the usual deformed grid test, nothing exciting: https://app.box.com/s/v3z5se5fl0a8zt1sw4ps

The ground texture was 20k, that took a little while to convert before the render started, but after that, I was suprised by the system ram, particularly as I couldn't even begin to view the instances in the viewport, bounding box only...

    doesn't work like that... i have to convince someone to buy it for
    the studio, then the graphics cards you guys talk about... 3
    titans!? we don't have those types of investments. we have an
    existing farm with cpus and lots of ram. if i want to render a
    sequence with redshift... i have to render it on workstations
    only. also, i am not going to convert elysium to work for redshift
    on my free time ;)

    i am sold on the value of redshift, i can see the value clearly! i
    just wanting to see how well this 'out of core memory' feature
    really works.

        Well Steven, for $100 bucks for the Beta maybe you can try
        it.  Will be awsome to have some feedback on such scene as
        Elysium.
