GPU Dilemma

MikeA wrote on 11/22/2013, 11:39 AM

AHHHHHhhhhhhhh!!! I'm putting together a new editing system and I THOUGHT I had just about everything ironed out but then I read Arthur S's thread and now questions about which GPU to choose are popping up. It was suggested that he change his GPU from the GTX 650 to the GTX 570 or one of the newer AMD R9 280 or 290 units. Can anyone explain to me why? Is it related to rendering speed, # of screens that can be connected (2 GTX 570s were also recommended), or what? Or point me in a direction that I can learn? I'm leaving off my parts pick right now because I want to be educated in the whys and where-fors of "this card" over "that one" from the gpu and SVP angle and not "this gpu will work better than that one with that MOBO/CPU combo". What does SVP want and what gpu will give it to it? I'm running SVP 10 right now and if I upgrade it will probably be down the road unless someone can make the case as to why I should with my new build.

Thanks!

Mike

No proxy in PP CC while playing back XAVC - just drop on the timeline (sequence they call it), and hit play... And the 90-100% I mentioned is the GPU usage (versus the 19% in Vegas), which shows the much better efficiency of GPU usage.

PS. Sorry - the Sequence Preview settings are indeed sort of "proxy" to XAVC at I-frame RGB in HD being the highest selectable quality, but this doesn't change my point of GPU utilization. In VP I never saw anything above 50% GPU load- be it playback or rendering. The Mercury engine uses the GPU to its limits in both...

I barked at the tree and now have a GTX 770 under the Christmas Tree.
Plus, I do a lot of gaming so I suspect it will all work out in the end.

as, perhaps, a final epitaph to this thread, can we please stop recommending obsolete hardware.

a. it's ok if you're diy, but otherwise asking a pro shop builder for obsolete hardware is laughable. (when i was getting quotes for my new pc and asking for a 570 / 580 the scorn poured on vegas was embarrassing to say the least)

b. my new card (650) uses half the power of my old (550), runs cooler and quieter and performs MUCH better than my old one in everything but vegas - where it seems pretty much the same - though i do use my int. pro for monitoring anyway.

c. it really is high time scs did something about the gpu situation; not only is it still confusing as to which card does what with which driver, but the competition, both ppro and edius make vegas look like a fisher-price toy in this department.

PLEASE NOTE: this IS NOT meant as criticism of the many who recommend getting 5xx cards, their observations are perfectly valid - but time moves on, and so should vegas.

a very happy humbug to one and all, and all the best for the new year,

and a special thanks to the scs team members who occasionally pop by and suffer our slings and arrows ;-)

Thank you all and I apologize for bringing up a sore subject although I did learn a lot. I'm comfortable with VP, but maybe it's time to go looking in another direction software wise since getting current hardware that works with current VP software seems to be a challenge. Uhhh, this sucks!!

Sorry to refresh a sore subject...

My GPU (GTX660Ti) just crashes and crashes in VP12b770 when GPU rendering is enabled. I'm NOT going to solve this by getting used second hand GPU hardware (like a GTX560/570/580).

I'm looking at a new Asus Radeon R9280X GPU. Can someone kindly confirm -

What is the success rate using this GPU (enabled :) with VP12?
Is the GPU rendering stable?
Are the latest drivers the best ones of do I have to download older drivers (as with NVidia)?
Is video prewied up to par with AVCHD source files?

In short - is this an excellent/stable GPU for VP12? If not - which is the BEST (non-bank breaking) GPU that works with VP12? Reliably!

SCS - please update your GPU rendering info page - its quite old and the information almost non-relevant! Please finally fix your problems with GTX6xx/7xx/Titan GPU's.

Cheers,

Christian

But you could solve it with a 5xx card and way cheaper then a new RX9. But as of now, it seems that the RX9 is the only new generation card that will get you good GPU acceleration in VP12. I am not in your situation as I have 2 GTX580 in my system but if your work is paid work, I still would rather get a second hand card for 150 and wait until VP is able to support new hardware and confirms it then experiment with an R9.

As for the SCS website, it is still accurate. If you look at all the comparison graphs, it still says GTX570 and 7950 and those work.

I'm using an R9 280X Christian. No problems whatsoever with rendering, but I am having some other problems with it. Do a search on my user name.

Not so sure 100% GPU utilization is necessarily more efficient, my guess is that in the programming someone is utilizing the strengths of the GPU vs CPU. I can make my GPU hit the ceiling in Vegas, if I apply the right effects to a single clip. So while Vegas may only run 30% on single clip playback, that 60% available is what keeps effects real time when you apply them. Fail playback on a timeline, to me, screams bad driver compatibility with the application. Remember Vegas lists on the website and most of the advertising that its leveraging OpenCL. So in my book that means select cards that do the best with OpenCL, and not cuda or crysis. If you look at the rank list below, the 2009 era HD5770 on the supported list, ranks up there with the 7 series Nvidia. I think that displays application optimization, or just how badly Nvidia is gimping compute capabilities of gaming cards. not sure which.

Note that the Anandtech bench is with XDCAM..

there is a 4 second spread between the R9 290X and the 270X while the former costs 3x as much...

I would like to know the length of the content they are rendering with there tests..

He mentions it is something from Sony and I would bet it is the project Sony created to showcase the GPU technology. The project is just short of 1 minute in length.

You can download the project on this page.
