The Latest CUDA App: MotionDSP’s vReveal
NVIDIA had more slides in its GTX 275 presentation about non-gaming applications than it did about how the 275 performed in games. One such application is MotionDSP’s vReveal - a CUDA enabled video post processing application than can clean up poorly recorded video.
The application’s interface is simple:
Import your videos (anything with a supported codec on your system pretty much) and then select enhance.
You can auto-enhance with a single click (super useful) or even go in and tweak individual sliders and settings on your own in the advanced mode.
The changes you make to the video are visible on the fly, but the real time preview is faster on a NVIDIA GPU than if you rely on the CPU alone.
When you’re all done, simply hit save to disk and the video will be re-encoded with the proper changes. The encoding process takes place entirely on the GPU but it can also work on a CPU.
First let’s look at the end results. We took three videos, one recorded using Derek’s wife’s Blackberry and two from me on a Canon HD cam (but at low res) in my office.
I relied on vReveal’s auto tune to fix the videos and I’ve posted the originals and vReveal versions on YouTube. The videos are below:
In every single instance, the resulting video looks better. While it’s not quite the technology you see in shows like 24, it does make your videos look better and it does do it pretty quickly. There’s no real support for video editing here and I’m not familiar enough with the post processing software market to say whether or not there are better alternatives, but vReveal does do what it says it does. And it uses the GPU.
Performance is also very good on even a reasonably priced GPU. It took 51 seconds for the GeForce GTX 260 to save the first test video, it took my Dell Studio XPS 435’s Core i7 920 just over 3 minutes to do the same task.
It’s a neat application. It works as advertised, but it only works on NVIDIA hardware. Will it make me want to buy a NVIDIA GPU over an ATI one? Nope. If all things are equal (price, power and gaming performance) then perhaps. But if ATI provides a better gaming experience, I don’t believe it’s compelling enough.
First, the software isn’t free - it’s an added expense. Badaboom costs $30, vReveal costs $50. It’s not the most expensive software in the world, but it’s not free.
And secondly, what happens if your next GPU isn’t from NVIDIA? While vReveal will continue to work, you no longer get GPU acceleration. A vReveal-like app written in OpenCL will work on all three vendors’ hardware, as long as they support OpenCL.
If NVIDIA really wants to take care of its customers, it can start by giving away vReveal (and Badaboom) to people who purchase these high end graphics cards. If you want to add value, don’t tell users that they should want these things, give it to them. The burden of proof is on NVIDIA to show that these CUDA enabled applications are worth supporting rather than waiting for cross-vendor OpenCL versions.
Do you feel any differently?

LOL - antoher hidden red rooster bias uncovered...Umm... look, when there's a new ati card, there's no talking about crunching down on former ati cards - OK ? That just is NOT allowed.
" No mention of the death of the HD 4850X2 as the HD4890 trashes the power consumption, price, availability, speed and OC-ability "
Dude, not allowed !
PS- Don't mention how this card is going to smash the "4870" "profit" "flagship" - gee now just don't talk about it - don't mention it - look, there's no rooster crying in fps gaming, ok ?

Props to ATi for delivering a very compelling product. I admit I've always been an Nvidia fan, and I'll generally forgive them a single generational performance loss to ATi, but I've recommended ATi products recently to friends due to their resurgent desirability.That being said, am I the only one who detects a subtle but distinct underlying disdain for Nvidia? So they tried to market the hell out of you - so what? They are trying to sell cards here. Why the surprise that sales and marketing people are trying to do exactly what they're paid to do? Congrats for being smart enough to see it for what it is, but jeers for making an issue of it as if its some kind of new tactic. Has AMD/ATi never done the same?
CUDA and PhysX are compelling, but I agree not a good reason to overcome a significant gap between Nvidia and ATi at a comparable price point. You clearly agree, but it seems like what little praise you offer is begrudging in the extreme.
Nvidia has definitely acted in bad form in a number of ways throughout this very lengthy generation of hardware. However, you guys are journalists and in my opinion should make a more concerted effort to leave the vitriol and sensationalism at the door, regardless of who it is that is being reviewed. That kind of emotional reaction, personal opinion, irritation, etc is better served for your blog posts than a review article.
Love the site, keep up the good work. Nobodys perfect.

Yeah thanks for noticing, too. It been going on a long time. Notice how now, suddenly when ati doesn't have 2560 sewn up - it doesn't matter anymore ... LOLOf course the "brilliiantly unbiased" reviewers will claim they did a poll on monitor resolution useage, and therefore sudenyl came to their conclusion about $2,000.00 monitor users, when they tiddled and taddled for years about 10 bucks between framerates and nvidia ati - and chose ati for the 10 bucks difference.
Yep, 10 bucks matters, but $1,700.00 difference for a monitor doesn't matter until they take a poll. Now they didn't say it, but they will - wait it's coming...
Just like I kept pointing out when they raved about ati taking the 30" resolution and not much if anything else, that declaring it the winner wasn't right. Now of course, when ati isn't winning the 30 rez - yes, well, they finally caught on. No bias here ! Nothing to notice, pure professionalism, and hatred of cuda and physx for it's lack of ability to run on ati cards is fully justified, and should offer NO advantage to nvidia when making a purchase decision ! LOL
OMG ! they're like GONERZ man.

Best review so far. And nice cards BTW, they are both worth it, but i like the 4890 betterFunny thing is that GTX 275 > GTX 280.
But my guess is that GTX 280 benefits more from overclocking.

Because of my PC's location I am concerned with idle power, and purchase based on that if other specs and price are even comparable. Peak power doesn't matter as long as it's within the capability of my 800W PSU.I bought an ATI HD4850 last year because it idled significantly lower than the 4870, and it would run everything in sight. A great card. The Nvidia GTX 260 and 280 had even better performance vs idle power ratios but were way too expensive at the time.
So I think Nvidia takes the laurels now with the GTX 275. 30W less (!) than the HD 4890 at idle, with essentially the same performance. If I were shopping now it would be a VERY easy choice.
I really hope ATI can get their idle power down too. They need to pay more attention to throttling back or downpowering circuits that aren't needed in 2D modes.

Use the radeon bios editor to edit the 2d profile and then downclock your gpu frequencies.OCedHrt - Friday, April 3, 2009 - link
The power consumption on the 4890 really interests me. While it uses more than 275 at idle, it uses less under load. Also, it is a significant drop from the 4870 which is a slower card.bobvodka - Friday, April 3, 2009 - link
So, on the charge of drivers; I've gone from recently having a GT8800GTX 512Meg to a HD4870X2 2gig and if anything I've seen stability improvements between the two. Or to put it another way NV drivers were bluescreening my Vista install when I was doing nothing more than using my TV card and it was crashing in a DirectDraw DLL. Nice.Not to say AMD hasn't had issues; trying to use hardware acceleration with any bluray play back resulted in a bluescreen due to the gpu going into an infinite loop. Nice. Fortunately, unlike the DDraw error above, I could at least turn off hardware acceleration (and honestly, with an i7 it's not like I needed it).
So, stability wise it's a wash.
As for the memory usage complaints about CCC;
Unless it is running it is NOT taking up physical memory. Like many things in the windows world it might load something into the background but this is quickly paged out and doesn't live in ram. Even if it does living in ram for a short period of time being inactive it will be paged out as soon as memory presure requires it. The simple fact is unused ram is wasted ram; this is why I'm glad Vista uses 10gig of my 12 for cache when it isn't needed for anything else, it speeds up the system.
Cuda.. well, the idea is nice and I like the idea but as mentioned in the article unless you have cross vendor support it isn't as useful as it could be. OpenCL and, for games, DX11's compute shaders are going to make life intresting for both Cuda and AMD's option. I will say this much; I suspect you'll get better performance from NV, AMD and indeed Larrabee when it appears by going 'to the metal' with them but as with many things in the software world you have to trade something for speed.
Now, PhysX.. well, this one is even more fun (and I guess it effects Cuda as well to a degree). Right now, with Vista, you can't run more than one vendor's gfx card in your system at once due to how WDDM1.0 works; so it's AMD or NV and that's your choice. With Win7 however the rules change slight and you'll be able to run, with WDDM1.1 drivers, cards from both vendors at once. Right away this paints an intresting landscape for those intrested; if you want an AMD card but also want some PhysX hardware power than you'll be able to slide in a 'cheap' NV series card to use for that reason (or indeed if you have an old series 8 laying about use that if the driver supports it).
Of course, with Havoc going OpenCL and being free for games which retail for <$10 (iirc) this is probably going to be much of a muchness in the end, but it's an intresting idea at least.

Except you can run 2 nvidia cards, one for gaming, the other for physx.... so red fanboys are sol."Right now, with Vista, you can't run more than one vendor's gfx card in your system at once due to how WDDM1.0 works; so it's AMD or NV and that's your choice. "
WRONG, it's TWO nvidia or just ONE ati. Hello - you knew it - but you didn't say it that way - makes ati look bad, and we just cannot have that here....

The hell are you talking about? Crossfire works in vista just fine.
