Someone who works in the Media Production field question about Adobe Suites and GPUs

I know Adobe prem/AE/ps use GPUs as accelerators but I have to ask, if I do purchase a laptop, would a gaming GPU (Nvidia 740m in this case) even show a significant boost in speed when using MPE, rendering, ect to worth adding on ? I know in the new creative cloud, you can use whatever GPU you want .

Yes, I know there are specific GPUs that work better but I'm asking specifically about gaming GPUs, if they have any worth in the video editing area .

Edit : this may not belong here, but since it say's "Software" I gave it a shot .

 

If it's a "professional" series GPU you're looking for, it would be an Nvidia Quadro or AMD FirePro. Both those lines are meant for Digital content creation. There are some gaming GPUs do better than others with regards to GPGPU...the AMD 7970m being one of them (so I'm told). But as far as comparing the gaming GPU lines (GeForce and Radeon) to the professional series for CAD and DCC, the professional series will win out.

 

The question was if a lower-end gaming GPU is even worth it over a iGPU .

 

Yes, if it takes advantage of OpenCL or Cuda, even if Nvidia's OpenCL performance with Kepler isn't good, it's still faster than iGPU.

 

This, for now,e ven the Keplers are slightly better than the Intel HD graphics at OpenCL. AMD absolutely destroys nVidia when it comes to OpenCL performance, but it can't do CUDA obviously. Only Premier is still CUDa enables in the current CS release, but if I remember correctly, even that is moving to Open CL with the next release.

AMD's 7970m is about 4 times faster in OpenCL than it's nVidia counterpart, the GTX680m. I don't have data on the 780m and 8970m, but given that the 700 series is still Kepler, performance in OpenCL won't really improve. The 780m is a beast when it comes to games though.

 

I see . Thanks !

Any predictions if Nvidia will open up some driver updates to improve OpenCL in the 7xx series ? Or even if the drivers will make an impact based off past notions .

Thanks !

 

Drivers only go so far, it's a hardware limitation that's at the core of the low OpenCL performance compared to AMD. nVidia went for a highly gaming optimized (makes sense) architecture with the Kepler gaming cards and compute performance took a hit as a result.

KCETech1 is probably the best person to get into the details since she uses Adobe software on a regular basis.

 

I believe with the Keplers NVidia severely restricted the GPU pipelines. I am not sure if it is hardware or driver created but probability is hardware limited as I am sure someone would have hacked it either by driver or vbios by now.

Another issue may be the iGPU if used by your system, driver conflicts and issues are always a looming possibility. The other issues is if the CPU is strong enough compared to a really low end GPU OpenCL may not be worth it, especially low end Kepler NVidia................

 

i have used ppro and ae 5.5 and of course mpe 5.5. unless there have been drastic changes in the way 6.0 up works (which i doubt), the adobe video suite only uses gpu acceleration for pre rendering previews for faster scrubbing, effects generation, etc. the actual rendering itself by mpe is a cpu process.
so why does it not use gpu rendering? all gpu rendering algorithms (cuda, opengl, etc) deliver subpar video output as compared to cpu only renders. in fact the best gpu renderer in terms of speed and quality is quicksync, but it is not supported by adobe or a lot of video editing programs atm.

edit:
so the question is, will a gpu speed up rendering in mpe (at least in 5.5)? the answer is no. but it will help your workflow become more manageable as being able to scrub and view gpu rendered effects in real time is a big time saver in itself.

edit edit:
ppro 5-5.5 (6?)
re nvidia gpu acceleration support, there is a white list of gpu's that adobe products work with, most of them are of course quadro and high end desktop cards. so if your nvidia gpu is not on the list, you cant use gpu acceleration. but there is a text file you can edit that will make ppro and ae work with any nvidia gpu. amd gpu's are not supported in these versions.

ppro cc
nvidia and amd gpu's supported but still with a white list. i dont know if you can edit the text file to add non-native gpu support on this.

hope that helped
