CUDA - Oh there’s More

Oh I’m not done. Other than PhysX, NVIDIA is stressing CUDA as another huge feature that no other GPU maker on the world has.

For those who aren’t familiar, CUDA is a programming interface to NVIDIA hardware. Modern day GPUs are quite powerful, easily capable of churning out billions if not a trillion instructions per second when working on the right dataset. The problem is that harnessing such power is a bit difficult. NVIDIA put a lot of effort into developing an easy to use interface to the hardware and eventually it evolved into CUDA.

Now CUDA only works on certain NVIDIA GPUs and certainly won’t talk to Larrabee or anything in the ATI camp. Both Intel and ATI have their own alternatives, but let’s get back to CUDA for now.

The one area that GPU computing has had a tremendous impact already is the HPC market. The applications there lent themselves very well to GPU programming and thus we see incredible CUDA penetration there. What NVIDIA wants however is CUDA in the consumer market, and that’s a little more difficult.

The problem is that you need a compelling application and the first major one we looked at was Elemental’s Badaboom. The initial release of Badaboom fell short of the mark but over time it became a nice tool. While it’s not the encoder of choice for people looking to rip Blu-ray movies, it’s a good, fast way of getting your DVDs and other videos onto your iPod, iPhone or other portable media player. It only works on NVIDIA GPUs and is much faster than doing the same conversion on a CPU if you have a fast enough GPU.

The problem with Badaboom was that, like GPU accelerated PhysX, it only works on NVIDIA hardware and NVIDIA isn’t willing to give away NVIDIA GPUs to everyone in the world - thus we have another catch 22 scenario.

Badaboom is nice. If you have a NVIDIA GPU and you want to get DVD quality content onto your iPod, it works very well. But spending $200 - $300 on a GPU to run a single application just doesn’t seem like something most users would be willing to do. NVIDIA wants the equation to work like this:

Badaboom -> You buy a NVIDIA GPU

But the equation really works like this:

Games (or clever marketing) -> You buy a NVIDIA GPU -> You can also run Badaboom

Now if the majority of applications in the world required NVIDIA GPUs to run, then we’d be dealing in a very different environment, but that’s not reality in this dimension.

    Congrats ATI, the 4890 is a strong performer! So much chatter about what constitutes rebadging; at the end of the day it's performance that matters. 4890 does a great job for the money.

    The GTX 275 performs well but lacks excitement IMO. Nothing surprising or exciting; we've already seen a 240 shader enabled gpu on a 260 style interface (x2). If anything, the 285 receives strong competition from both 4890 and 275. Makes little sense to remain at it's price point. It's price should be $300.

    Times are tight. Cheers to competition...

    I can't believe how biased anandtech has become.
    I've checked all other review sites and in all the GTX275 was winning by a pretty big margin, here it actually looses to the HD4890.

    Now I'm not a fanboy for either, I've had 2 nvidia graphic cards and 2 ATI cards, the current one is ATI, but this bias thing can't go un-noticed.

    Some investigators must be summoned to deal with anandtech, this has been going for quite a while now.

    I see the difference.. those "other reviews" used the Catalyst 9.3 drivers.

    Anandtech, HardOCP and Firingsquad used the new 9.4 Beta drivers.

    No bias on Anandtech's part. Rather a bias from those other sites who used the new nVIDIA BETA driver but not the ATi one that has proper support for the 4890.

    I dont normally take notice of comments like this on here, but it does seem a little like it. It's as if NV have pissed off Anandtech with there dirty tactics (understandable), and Anandtech are being a little bias because of this.

    I've looked at three reviews (FiringSquad, THG, and HardOCP - also Xbitlabs, but they didn't have the GTX 275 in their results). I'm not quite sure what horribly biased and inaccurate results we're supposed to have, as most of the tests are quite similar to ours. Two sites - HardOCP and FiringSquad - essentially end up as a tie. THG favors the 275, at least at lower resolutions and without 4xAA, but then several of the games they test we didn't use, and vice versa. (The 4970 also beats the 275 there if you run 4xAA 2560x1600.)

    Obviously, we had a lengthy rant on CUDA and PhysX and discussed the usefulness of those features (conclusion: meh), but with all the marketing in that area it was something that was begging to be done. Pricing, availability, and drivers are still areas you need to look at, but it's really a very close race.

    If you have reviews that show very different results than what I'm seeing, post the name of the site rather than making vague claims like, "I've checked all other review sites and in all the GTX275 was winning by a pretty big margin, here it actually looses to the HD4890."

    That's different then what I've seen. I dunno what sites you visit but all of the ones I've been to show them just about neck and neck or the 4890 just edging out the 275.

    Personally I give the edge to the 4890 due to it's high overclockability.

    p=2 As we can clearly see, in the cards we *r*ested
    p=11 particles are one of the most difficult things to do on the CPU *thanks*

    Drivers? test table says 8.12 hotfix but we're at 9.3/9.4 now...
  • Yojimbo - Thursday, April 2, 2009 - link

    First you say you aren't concerned about the 4890 being a rebadge because at the end of the day it's performance that matters, and then you said the GTX 275 lacks excitement because "we've already seen a 140 shader enabled gpu on a 260 style interface (x2)," whatever the significance of already seeing that is.

    Aren't these contradictory statements?
  • SiliconDoc - Thursday, April 23, 2009 - link

    Of course it's contradictory, it's a red rooster statement. Then the 3m they use to just crank a few more mhz is the rework.. LOL
    Pay homage to the red and hate green and spew accordingly with as many lies as possible or you won't fit in here - been like that for quite some time. Be smug and arrogant about it, too, and never amdit your massive errors - that's how to do it.
    Make sure you whine about nvidia and say you hate them in as many ways as possible, as well - be absolutely insane mostly, that's what works - like screaming they can take down nvidia when the red rooster shop has been losing a billion a year on a billion in sales.
    Be an opposite man.
    Of course it's contradictory. Duhh.. they're insane man - they are GONERS.
