When you render on the CPU directly from your DCC app, you have your scene in
mem twice. Once in e.g. Soft, and once translated into what the renderer can
render, both are stored in RAM, hence the memory consumption appears relatively
high. In case of Redshift, video memory on the card (VRAM) is used for storing
translated, renderable scene data, as long as it fits in.
Translated scene data is usually a lot more efficient to store than the actual,
raw scene, which has a lot of metadata, construction history, etc, that is not
needed for rendering. Hence, a scene consuming 10gb in RAM is usually easily
renderable on a 6gb card, depending on how much additional unique and
procedural geometry you create at render time (e.g. subd, displacement, hair).
There was a thread in the Redshift forum regarding actual triangle numbers
storable in certain amounts of Vram. I can't find that thread now, but I
believe it was around 100mio unique triangles in 6gb of Vram?
no, vram only gets used by the card it's built in.
but 6 gb vram is quite a lot and can't be compared to cpu ram.
Means, if your scene uses like 15gb in Vray that doesn't mean 6gb is not enough
for the scene in Redshift.

If you have two 6gb cards, does Redshift consider this as 12gb of RAM or only
6gb?

Last time I checked they were more expensive than two separate titans.
What about the titan z series? Are they out yet? They could probably pack quite
a punch :)

I second that, the 780 with 6gb (~2300 cores vs ~2800 of the Titan) is
currently the biggest bang for the buck.
Make sure to get the one that adheres to NVidias reference cooling design to get rid of the
heat at the rear instead of >>>>>injecting it into the pc housing, as the
other, cheaper one from EVGA does.
hey,
the titan black is very fast, but considering the benchmarks
(http://www.videocardbenchmark.net/high_end_gpus.html) the >>>>>>780 isn't lame
either, and the 6gb version is close to half the price of a titan.
so if you want a bargain that's still fast, I would go for the 780 6gb.

Hi, now that Redshift is officially out and running smoothly, I´d like to ask
you guys what
Graphic Cards for best GPU performance would be optimum for an I7 stream core?
I´m taking a look at:
EVGA EVGA GeForce GTX TITAN SuperClocked 6GB GDDR5 384bit, Dual-Link DVI-I, DVI-D, HDMI,DP, SLI
Ready >>>>>>>Graphics Card Graphics Cards 06G-P4-2791-KR
But if I recall, there were some threads that were posted about the performance
of the Quadro K4000 vs Titan.
I can afford something of 1k cost ($1000) but before buying I would like to ask
if there´s a better (cheaper) option?
Like you all guys know, I´d like to take these considerations with softimage
and later on the year
transition fully to Modo 801.
So what are your thoughts / recommendations?
Thanks for sharing.
David.
