Thanks for that John glad it confirmed what was already known.

I am curious though…is there not any sort of text file in Vegas that can be edited to include other open CL cards or is it something more complicated about the way the 7 series cards work etc ?

I know in Premiere Pro it is a simple matter of just editing a text file list with notepad to include extra cards …it works well as I added my GTX560Ti and it was recognised in the ‘Mercury Playback Engine’ no problem.

Can’t seem to find anything about doing it in Vegas though.

I recently got a new PC and was eager to how it performed rendering in Vegas Pro 13 with 2 different GPU’s ..the one that it came with and another one I had in my old machine so here are the results.

The 2 graphics cards compared are a XFX Radeon HD 7850 2GB and an MSI Geforce 560ti 1GB TwinFrozr

1st of all the spec of the base machine.. nothing other than the Graphics cards was changed during the tests.

Intel Media Series DH77EB mATX Motherboard
Intel i7-3770K 3.5GHz Quad Core Processor (unclocked)
Kingston 32GB (4 x 8GB) 1600MHz DDR3 Memory
Intel 520 Series 180GB 2.5″ SSD – OS Drive (Vegas Pro 13 installed on this as well)
Seagate 3TB SATA Hard Drive – Data Drive
Microsoft Windows 8.1 Pro 64-bit OEM

I used JR’s render test and used the latest drivers for the cards …uninstalling each cards driver before I installed the other ones driver.

Sorry in advance if I haven’t laid out the results in the best way but all the info is there and I don’t understand how to do spreadsheets etc 🙂

All settings as recommended by John ie preview window set to 900×506 and ‘Best Full’

As I will be mainly burning my projects (my holiday videos) to blu ray I thought I would try a blu ray setting as well so have included those.

—————————————————————————————————————-
FIRST THE RADEON HD 7850 2GB:
———————————————–

All the following are with ‘GPU Acceleration’ set to OFF … I was getting 0.5 FPS on the preview playback.

Render as Sony AVC Internet 1920×1080 30p : 01:06
Render as Sony AVC Blu ray 1920×1080 24p 16mbts 00:53
Render as Main Concept AVC/AAC Internet HD 1080p : 01:28
Render as Main Concept AVC/AAC Blu ray 1920×1080 24p: 01:24

Obvoiusly with GPU Acceleration set to OFF the figures were the same for ‘CPU Only’ Auto’ and ‘Use Open CL If Available’…I did try them all.

———————————————

All the folowing are with ‘GPU Acceleration set to ON…I was getting 29 FPS on the preview playback.

Render as Sony AVC Internet 1920×1080 30p ‘CPU ONLY’ : 00:16
Render as Sony AVC Internet 1920×1080 30p ‘AUTO’ : 00:19
Render as Sony AVC Internet 1920×1080 30p ‘ USE GPU IF AVAILABLE’ : 00:19
Render as Sony AVC Blu ray 1920×1080 24p 16mbts ‘CPU ONLY’ 00:13

Render as Main Concept AVC/AAC Internet HD 1080p ‘CPU ONLY’: 00:35
Render as Main Concept AVC/AAC Internet HD 1080p ‘USE OPEN CL’: 00:36
Render as Main Concept AVC/AAC Blu ray 1920×1080 24p: 00:42

and one extra :
Render as Main Concept Mpeg2 Blu ray 1920×1080 24p 25mbs : 00:07
—————————————————————————————————————-

NOW WITH THE GTX 560Ti
————————————–

All the ‘GPU acceleration’ set to OFF figures where of course the same as above
—————————————————————————————————

All the following are with ‘GPU Acceleration set to ON…I was getting only14 FPS on the preview playback

Render as Sony AVC Internet 1920×1080 30p ‘CPU ONLY’ : 00:22
Render as Sony AVC Internet 1920×1080 30p ‘AUTO’ : 00:25
Render as Sony AVC Internet 1920×1080 30p ‘ USE GPU IF AVAILABLE’ : 00:24
Render as Sony AVC Blu ray 1920×1080 24p 16mbs ‘CPU ONLY’ 00:17

Render as Main Concept AVC/AAC Internet HD 1080p ‘CPU ONLY’: 00:42
Render as Main Concept AVC/AAC Internet HD 1080p ‘USE CUDA’: 00:21
Render as Main Concept AVC/AAC Blu ray 1920×1080 24p ‘CPU ONLY’: 00:45
Render as Main Concept AVC/AAC Blu ray 1920×1080 24p ‘USE CUDA’: 00:45

and one extra :
Render as Main Concept Mpeg2 Blu ray 1920×1080 24p 25mbs : 00:13
————————————————————————————————-

Conclusions:

1) Using ‘USE OPEN CL’ made no difference in any test so is not being utilised for this particular Radeon card

2) The Radeon card was still faster than the GTX at all tests though exept Render as Main Concept AVC/AAC Internet HD 1080p ‘USE CUDA’ where the GTX beat it by about 80%

3) The Radeon card also gave double the FPS in playback of the GTX on Full Best at the 900×506 setting….btw if I reduced the size of the preview screen or set it at anything less than ‘Full Best’ for the GTX 560 Ti I was able to get the full 29 FPS.

4) Curiously in the Main Concept Bluray settings the 560 Ti was the same with or without CUDA being used yet on the ‘Internet HD 1080p’ CUDA halved the time…I also tried it on the Main Concept AVC/AAc ‘Sony Tablet 1080p’ and the ‘Apple TV 720p 24’ and CUDA did cut these times by the same 80% or so. So not sure why it doesn’t cut times on the Bluray settings…..it wasn’t a glitch as I tried it multiple times.

5) Since the Radeon (even without specific support for Open CL) is faster all but one than the GeForce card I will be using the Radeon so it’s now back in the PC again (you were right John :))

Hope this hasn’t seemed too drawn out but I know that too many details are better than too little.

One final question for you guys ..Since as mentioned I will mainly be doing blu rays is there any disadvantage in using (A) ‘Main Concept MPEG2 Blu Ray 1920 x1080 25mps’ over (B) ‘ Sony AVC Blu ray 1920×1080 24p 16mbs’?

A is twice as fast as B for me and is the fastest of all the tests and it seems it will be even better quality at 25mps as opposed to 16mbs….or am I missing something?

The material I will be using will be mainly GoPro footage at superwide 1080p 50 fps.

Hi John

I get the wink wink 🙂

Yes the PC has arrived and am now doing all the install of my stuff on it.

I will try all tests with your render test with each different card and post the results here.

It may take me a week or so coz the new PC is running windows 8 and I have got to get my head around that as well 🙂

Hi Steve

Thanks for that… Good advice…will only be using one card the new PC arrives today so am looking forward to trying it out.

Annoying that older series cards will work better than newer series cards though. On advice of you and others I will be swapping the GTX 560ti into the new PC and putting it’s Radeon 7850 in the old machine where it will still be fine for games and non video editing stuff.

Yes I agree I could have worded the title better but on reading the text is is clear I was just asking about a choice between using one or other cards hence me thinking Mr Osbun’s response calling me a smart ass was abit OTT.

Thanks Again

Tom

[Tom Ross]

Wow…no need for that…I thought my response was well mannered.

I thought it was pretty clear what I was asking in my post and your reply was nothing to do with my question…that’s all I said but feel free to ignore me if you think I am a ‘smart ass’ I have no problem with that.

Hi David

Thanks for that and not a bad idea trouble is that would leave me with no graphics card in my old PC which I am keeping.

Was going to just use my ‘new’ PC for the more intensive stuff like Vegas and Photoshop and keep it uncluttered with the bloatware that seems to accumulate.

My old PC will be side by side with it in my ‘observatory/man room’ controlling the telescope and web surfing and playing the not too graphics intensive (but still needing an average card) games I tend to play which it does well, and I can be using it for example while also using the new one.

Tom

[Tom Ross]

Thanks for that Dave…looks like I will be swapping cards over then.

Tom

[Tom Ross]

Dave I am unsure what you mean?

I am not asking about dual cards??…I am asking which single card to use…did you actually read my post or just the title?

Tom
