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?

Don't worry, it is mentioned in the article their overclocking didn't have good results, so they're keying up a big fat red party for you soon.They wouldn't dare waste the opportunity to crow and strut around.
This was about announcing the red card, slamming nvidia for late to market, and denouncing cuda and physx, and making an embarrassingly numberous amount of "corrections" to the article, including declaring the 2560 win, not a win anymore, since the red card didn't do it.
That's ok, be ready for the change back to 2560 is THE BESt and wins, when the overclock review comes out.
:)
Don't worry be happy.

SD, you seriously have a mental problem right?I noticed that you keep bashing, being sarcastically insultive (betwen other things.) to anyone who supports ati.

No, not true at all, there are quite a few posts where the person declaring their ATI fealty doesn't lie their buttinski off - and those posts I don't counter.Sorry, you must be a raging goofball too who can't spot liars.
It's called LOGIC, that's what you use against the lairs - you know, scientific accuracy.
Better luck next time - If you call me wrong I'll post a half dozen red rooster rooters in this thread that don't lie in what they say and you'll see I didn't respond.
Now, you can apologize any time, and I'll give you another chance, since you were wrong this time.

I just finished a mid-range C2D build, and decided to go with the HD 4870 512MB version for $164.99 (ASUS, no sale at NE, but back up to $190 now). This was my first ATI card and it was a no-brainer. While the 4890 is a better card, to me, it is not worth the nearly $100 more, especially considering I'm gaming at either 1920x1200 on a 40" LCD TV or a 22" LCD monitor at 1680x1050.Nvidia has lost me after 12 years as a fanboy for the time being, I suppose. What I will do here when I have more time is determine if buying another 4870 512MB for CrossFire will be the better bang for my resolutions or eventually moving up to the 4890 when the price drops this summer and then sell the 4870.
Thanks for the GREAT review AT, and now I have my homework cut out for me for comparisons with your earlier GPU reviews.

Good job with tidying up the conclusion Anand.Russ2650 - Thursday, April 2, 2009 - link
I've read that the 4890 has 959M transistors, 3M more than the 4870.Gary Key - Thursday, April 2, 2009 - link
That is correct and is discussed on page 3. The increase in die size is due to power delivery improvements to handle the increased clock speeds.Warren21 - Thursday, April 2, 2009 - link
Maybe the tables should be updated to reflect this?Gary Key - Thursday, April 2, 2009 - link
They are... :)helpmespock - Thursday, April 2, 2009 - link
I've been sitting on my 8800GT for a while now and was thinking about going to a 4870 1GB model, but now I may hold off and see what prices do.If the 4890/275 force the 4870 down in price then great I'll go with that, but on the other hand if prices slip from the new parts off of the $250 mark then I'll be tempted by that instead.
Either way I think I'm waiting to see how the market shakes out and in the end I, the consumer, will win.
