Dual GPU Graphics

Many Edit programs have recently added support for Intel HD Graphics and Intel Quick Sync for H.264. Some claim up to 5X render speed improvements using Quick Sync hardware encoding - which is supported in PDR14/15.

I just bought - but not yet installed- a Gigabyte G1 GTX960 4GB GPU for other video graphics work (compositing) and would like to know the following:


  1. Can I set up the GTX GPU without losing Quick Sync for rendering?

  2. Can my PC access both GPUs with a single monitor?

  3. Will PDR render using Quick Sync with two cards?

  4. How does GTX H.264 encoding compare to Quick Sync?

  5. Will PDR use the GTX GPU for GPU optomized effects etc?


I'm hoping someone like Jeff (JL_JL) who has done so much GPU research with PDR14/15 can assist me.

Thanks

Al

AIS. wait little bit longer for the Kabylake! it'll be here 1Q 2017.

PD has been supporting GPGPU. lately due to nVidia driver issues, PD will utilize only one GPU in laptops.



anyway for your ?

ref see -> http://forum.cyberlink.com/forum/posts/list/46535.page#241962



my opinion you'd have gotten the GTX 1060 instead of GTX960.

tell Santa or Mrs.Santa for a return.




  1. yes and no. see ref link above

  2. no. one at a time.

  3. no. Quick Sync is intel not nVidia.

  4. ?. see ref link above

  5. yes, if nVidia GPU is selected.




there. now Jeff can kick my butt. GIGOTS man.

merry christmas everyone.



happy happy joy joy

p.s.

send a pm to Jeff about your ? for a response...

Thanks PepsiMan,

I've been postponing an upgrade since PDR12. Intel's "tic tok" has been a bit of a disappointment since Haswell. My little i5 with Intel HD graphics 4600 gpu is still going and when I edit 4k, Magic+PD works fine with PDR.

KabyLake looks promising for desktops. Recent reviews: "Intel’s media engine will decode VP9 and HEVC 10-bit codecs, which covers the most popular Ultra HD formats, especially for streaming." and "Kaby Lake also offers integrated GPUs better-suited to 4K video. Thanks to a new media engine built on a Gen9 graphics architecture, users can edit real-time 4K video using nothing more than integrated graphics." Quite a claim for a "free" integrated low power GPU.

I'm not a gamer but I'm amazed at the power packed into modern GPUs - but still confused about how little most programs seem to use it. Games written for GPUs and DirX 12 show that every extra $ you spend is a better benchmark. Editing software was more CPU oriented. Benchmarks are difficult to find for pro software but most I saw last year showed more performance improvement from new i7 6,8, & 10 core CPUS than gained from top GPU cards. My understanding is that edit software only benefits from GPU power with effects etc optomised for OpenCL, certain codecs like MYUV which are GPU optomised, and rendering for H.264 & H.265. But it's still a grey area to me. Plus pro software like Edius Pro 8 and DaVinci Resolve 10.5 have recently added Intel graphics support. Seems Intel GPUs rate at the bottom of gaming benchmarks but make a difference to edit software. Blackmagic and Iris™ Graphics: A Match Made at Intel . Comparing H264 encoding in EDIUS to other programs

So I got the Gigabyte GeForce GTX 960 G1 4GB for BM Fusion 8 compositing/graphics software I am learning - similar to Adobe After Effects. It's GPU intensive and needs a 2Gb gpu. I'll o/clock it to 1500Mhz. I contacted a Fusion user who recommended the card.

I would have preferred a GTX1060 or a 1080 but Santa got the 960 becuase it was on special - and I have a DJI Mavic Pro 4k drone on my Christmas list

Thanks for the links - still a bit confused. How does "Multi-GPGPU" work in Win 10? New card should arrive this week so any tips will be greatly appreciated.

PM- Next upgrade from GIGO to GIGOTS!!

Thanks,

Al
