A8- 3650/3850 and Sony Vegas Pro 11 (open CL)

[pc999]

Hi,

I am considering getting a APU for doing some more serious video editing on Sony Vegas, one app that as far as I know have excellent multicore and GPU acceleration.



What I would like to know is if you can get decent framerates (25+ fps) witha A8-3650/3850 while editing on a multicamera setting, up to 4-5 HD videos??? (preview: preview-auto quality)



I thought on a i5 but it is more expensive and maybe not as good given the GPU, the i3 is about the same price, but even in CPU the advantage should be quite small (if any, or worst, given that the app is very well threaded, no?). I also fancy this APU for some light PC gaming (I am a console guy), and other multimedia stuff (like audio, not accelerated by GPUs as far as I know)


I currently have a a X2 4850 + 3200 (GPU without open CL) and I barely get playable framerates with 2 cams, this CPU alone (according to bench) should be up to 3x faster in threaded app, plus the whole GPU side. Should be quite a nice upgrade IMO.


Anyone tried or know?


PS: I am actually waiting for trinity, but anything above this APUs I just want to consider as headroom, I may also save some power and go to the 65w trinity.

Thanks.

Look at the rig in my sig. With Vegas Pro 10e and no GPU acceleration I can preview full framerate 1080i with crossfades and straight cuts with preview at Best/Half. Framerate generally stays in the 20's with some light color correction applied.
A8 GPU is too weak to be useful in Vegas. You will need a more serious discrete GPU for the type of preview you are looking for.

Thanks, for the info, if you dont mind...

Have you ever tried a multicam setup with that CPU?
What kind of GPU would I need, a 7750, would suffice? (it seems around a 6800 in open CL)

Also I wouldn't mind using just HD (720) as project settings to preview the video, or a lower preview quality while I am just choosing takes.

I am really new in Vegas Pro, it seems really nice as I am starting to feel the need to do some more serious/complex video editing, but money is tight at the moment. IIRC I also saw somewhere a article that said it would actually be better to have a weak cpu and a strong gpu than the other way around (but I still doubt that my X2 can have any future on this).

Thanks in advance, again.

CPU should be able to handle multicam if you aren't doing lots of fx or PIP. But since I'm not GPU accelerated I can't give you the answer you need. I suggest this forum as all the experts are there for Sony Vegas.

I've never run Sony Vegas software, but
An A8-3850 would be a min of 2x as fast as the X2 4850 + 3200 you describe. The cpu has 2x the cores, 2x the cache per core, clocked 400MHz faster, and other minor tweaks. The GPU would do circles around the integrated 3200. Just get fast memory and a motherboard that'll let you set it 1866 speed or higher with tight timings for best results.

We all want to see trinity come out
