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.

    I haven't checked the benchmark numbers yet, but you list Forceware 185's on the NV side, and Cat 8.12's on the AMD side.
    Any reason why you are using brand new drivers for one side and 4 set old drivers on the other?
    Sure, NV might not support a card on older drivers etc, but it's more useful to see newest driver vs newest driver, since there are performance changes from 8.12's to 9.3's in various games, but it just seems silly to use 3+ month old drivers which have been superseded by 3 revisions already. Would anyone buy a brand new card and then use drivers from 3~4 months ago?

    The setup chart has been updated. We utilized previous test results from the HD4870 with the 8.12 HotFix drivers. The HD 4890 results were with the 9.4 beta drivers. I just went through a complete retest of the HD4870 with the 9.3 drivers and just started with the 9.4 betas on the AMD 790FX and Intel P45/X58 platforms. Except for a slight performance improvement in Crysis Warhead on the P45/X58 systems, the 9.3 drivers offered zero performance improvements over the 8.12 HotFix. The 9.3 drivers do offer a few updated CF profiles and improved video playback performance, but that is it.

    "the 9.3 drivers offered zero performance improvements over the 8.12 HotFix."

    Not only that, but if you read the ATI forums, a lot of people have been having MAJOR problems with 9.2 & 9.3. I downloaded 9.1 for my new 4870 build and have had no problems.

    Now now, ati doesn't have any driver problems, so don't you DARE go spreading that lie. You hear me ?
    Hundreds of red roosters here have NEVER had a driver problem with their ati cards.
    Shame shame.

    Stop posting, seriously, you're stupidity is causing me pain.

    Another personal attacker without a single counterpoint to the many lies I've exposed. Good job brainwashed fool.

    Thanx - good to know.

    The Inq or The Reg is pretty adamant about the 275 being there just to spoil the 4890 launch, but never really in stores, and reviewers getting special hi-specs, hi-overclock hand by nVidia instead of the manufacturers.

    Did your card come from an anonymous purchase, or was it a special review sample ?
  • Gary Key - Thursday, April 2, 2009 - link

    We mentioned in the article that we received a review sample from NVIDIA. The clock speeds are the same as the retail cards that should start arriving later next week with widespread availability around the week of 4/13. Our retail review samples will arrive early next week.

    As we stated several times in the article, this is a hard launch for AMD and yet another paper launch for NVIDIA, although according to the board partners the GTX275 is coming quickly this time around.

    I also feel confused and somewhat misled by the conclusion that the GTX275 is "the marginal leader at this new price point of $250".

    That conclusion doesn't seem true outside of resolutions of 2560x (30" monitor). Plus, $250 cards aren't even targeted or seriously considered for gaming at that resolution.

    I came up with a different conclusion after thoroughly reading this review:

    At the $250 price point and 1680x or 1920x gaming resolutions (where these cards primarily matter), the 4890 holds the majority performance advantage. However, at 2560x the GTX275 performs a bit better than the 4890. Realistically though, at 2560x or on 30+" displays, you're best served by a dual GPU or SLI/Xfire solution.

    Something's fishy about the reviewers' conclusion.
