To add to the subject, is there a Redshift benchmark with different
graphic cards ?
Will be fun to have renderfarm only filled with graphic cards :)

Hi Nicolas,
I'm curious in how far GPU memory impacts render time. To put it
differently: Assuming the amount of cores is what makes the biggest
difference in render time, what's the expected speed differences
comparing a graphics card with 1gb to one equipped with 2gb or more?
Cheers,
Stefan
Hi Mirko,
Redshift does use the CPU for a couple things here and there so the
CPU is
not irrelevant to the performance, but it's not a big contributor.
For example, the RT hierarchy construction (construction of the
acceleration structure for raytracing) is done on the CPU as is texture
conversion to our optimized tile format. Also the screen-space adaptive
tessellation and some rebalancing of tree data structures for the
point-based techniques run on the CPU.
All in all though the GPU spec is what is really going to make the
difference for Redshift, assuming we're not talking about a 486 or
something :)
So yeah I encourage you to dust off that old PC, pop in the GTX580
and take
it for a spin. I think you'll be pleasantly surprised.

just wondering.. if everything is on GPU in theory it should work fine
even with some slower older CPU?
Got some older comp laying around and both PCI slots in comp are
filled,
maybe could use that one for GPU rendering station for testing :)
any thoughts?

No kidding! I can't imagine why Nvidia/Arc/MR whatever they're
called
now couldn't have done this years ago. Between them and AD they
can't even
get they're basic features working.
Money should be directed to these 3rd party guys as much as
possible. AD
must have called me about 10 times to renew my sub. This time I
said no, I
think I'll spend that on the guys getting results.
If you haven't tried this yet, do!

resources that are probably hard to imagine by any of us never got
to make
ANYTHING nearly great as anything like what we see from 3rd party guys
around.
If you think about it like 99% of progress is NOT made by big
companies. Really need to think in which direction money flow could
start
to change.. away from AD-like and more towards guys like Redshift
team :)
All the best!

Hey guys,
I'm going to respond to the last few messages regarding the
importance of speed later, but in the meantime here is a video of
some live
rendering in Softimage.
