Photoshop does not use CUDA but Mercury Graphics Acceleration.
As for the rest believe the knowledgeable people have already debunked your theory.
i mean cuda as in Photoshop is gpu enabled,
i read that when using the gpu color is not as accurate. as when using only cpu rendering than using the
Mercury Graphics Acceleration.
how is that theory.
i cant help it that all of you are retarded (those that think oh its a theory)
when all im asking do i get any performance gains with having more available processors.
and its not a theory, im simply asking is there any speed, up when getting more cores, beyond 12.
how may i ask is it a theory when it is a question.
im not saying well theoretically blah blah blah, i suck dick ... blah... lol all i am is seeking the answers to my questions so i can move on
and plan and narrow and accurately gauge my future purchase's acordingly.
once someone gives an accurate answer with proof, and not just saying, "nah man theres no speed up or oh yeah i think man its only 5% each time you double your core count b/s" man its not faster
but it'll make one hella pizza with devilitry magical toppings that give an amazing terror pleasureable awesome dreams
which the likes cant even compair to ("Diablo 3 cinematics and wow uber voxel / unreal 4 / future awesome / ati voxel demo that look damn near identical to real life in 2008 that they were working, mind bending awesomeness") TASTEing pizza
instead of fact's
lol i have alot of fun. even with/-/out said etheroic, "said" "alledged graphical" tasting pizza,
CUDA is a specific technology on NVidia cards.
It is not the same thing as GPU enabled, by a long shot.
GPUs can get the same color accuracy as the CPU, but there are problems in a few GPU shaders (and drivers) that can cause reduced accuracy or bugs/artifacts.
For more CPU cores: only a few things that are compute bound will really benefit like raytracing, Radial Blur, median, etc. Things that are RAM bandwidth bound (or close to it) won't see any benefit from additional cores.
More cores is always a matter of diminishing returns.
More video cards won't really help Photoshop -- Photoshop can only use one GPU at a time. Multi-GPU setups aren't designed for Photoshop-like usage, only for game-like usage. The GPU vendors are going to improve that, it just isn't here yet.
Thank you for your kind and well thought out & coherently structured msg, that is well laid and thought out, concise and to the point
i know it's not possible to use sli, in Photoshop, i did read while sli doesn't work.
i read some people said if you have them in you computer and NOT in sli then you can use them, more than 1, such as i mention cuda, i mean parallel. not in sli,
"Multi-GPU setups aren't designed for Photoshop-like usage" thats why i was ask, do you know if the tesla cards would make much difference?
do you know if i can use amd gpu's?
and do you know when that diminishing starts. for intel or amd opteron cpu's?
are there any other image manipulation programs that do use alot of cores or are better gpu supported?
Thank you very, your information helps
AMD and NVidia GPUs work about the same in Photoshop -- the only issues are the quality of the drivers.
Intel GPUs -- I wouldn't bother, they have many driver issues and are still underpowered.
Intel is trying to catch up, but has not done so yet.
After Effects, Premiere, and SpeedGrade use GPUs quite extensively. AE and Premiere do tend to do better with NVidia GPUs.
