Putting this PhysX Business to Rest

Let me put things in perspective. Remember our Radeon HD 4870/4850 article that went up last year? It was a straight crown-robbing on ATI’s part, NVIDIA had no competitively priced response at the time.

About two hours before the NDA lifted on the Radeon HD 4800 series we got an urgent call from NVIDIA. The purpose of the call? To attempt to persuade us to weigh PhysX and CUDA support as major benefits of GeForce GPUs. A performance win by ATI shouldn’t matter, ATI can’t accelerate PhysX in hardware and can’t run CUDA applications.

The argument NVIDIA gave us was preposterous. The global economy was weakening and NVIDIA cautioned us against recommending a card that in 12 months would not be the right choice because new titles supporting PhysX and new CUDA applications would be coming right around the corner.

The tactics didn’t work obviously, and history showed us that despite NVIDIA’s doomsday warnings - Radeon HD 4800 series owners didn’t live to regret their purchases. Yes, the global economy did take a turn for the worst, but no - NVIDIA’s PhysX and CUDA support hadn’t done anything to incite buyer’s remorse for anyone who has purchased a 4800 series card. The only thing those users got were higher frame rates. (Note that if you did buy a Radeon HD 4870/4850 and severely regretted your purchase due to a lack of PhysX/CUDA support, please post in the comments).

This wasn’t a one time thing. NVIDIA has delivered the same tired message at every single opportunity. NVIDIA’s latest attempt was to punish those reviewers who haven’t been sold on the PhysX/CUDA messages by not sending them GeForce GTS 250 cards for review. The plan seemed to backfire thanks to one vigilant Inquirer reporter.

More recently we had our briefing for the GeForce GTX 275. The presentation for the briefing was 53 slides long, now the length wasn’t bothersome, but let’s look at the content of the slides:

Slides About... Number of Slides in NVIDIA's GTX 275 Presentation
The GeForce GTX 275 8
PhysX/CUDA 34
Miscellaneous (DX11, Title Slides, etc...) 11

 

You could argue that NVIDIA truly believes that PhysX and CUDA support are the strongest features of its GPUs. You could also argue that NVIDIA is trying to justify a premium for its much larger GPUs rather than having to sell them as cheap as possible to stand up to an unusually competitive ATI.

NVIDIA’s stance is that when you buy a GeForce GPU, it’s more than just how well it runs games. It’s about everything else you can run on it, whether that means in-game GPU accelerated PhysX or CUDA applications.

Maybe we’ve been wrong this entire time. Maybe instead of just presenting you with bar charts of which GPU is faster we should be penalizing ATI GPUs for not being able to run CUDA code or accelerate PhysX. Self reflection is a very important human trait, let’s see if NVIDIA is truly right about the value of PhysX and CUDA today.

    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.
