Intel Caught Cheating In 3DMark Benchmark 216

EconolineCrush writes "3DMark Vantage developer Futuremark has clear guidelines for what sort of driver optimizations are permitted with its graphics benchmark. Intel's current Windows 7 drivers appear to be in direct violation, offloading the graphics workload onto the CPU to artificially inflate scores for the company's integrated graphics chipsets. The Tech Report lays out the evidence, along with Intel's response, and illustrates that 3DMark scores don't necessarily track with game performance, anyway."

      Except the article clearly shows that the name of the games executable determines frame rates in some cases. It then goes on to state:

      the very same 785G system managed 30 frames per second in Crysis: Warhead, which is twice the frame rate of the G41 with all its vertex offloading mojo in action. The G41's new-found dominance in 3DMark doesn't translate to superior gaming performance, even in this game targeted by the same optimization.

      This kind of offloading is definitely shady. I can't see how they'd get the driver approved.

      • "The G41's new-found dominance in 3DMark doesn't translate to superior gaming performance, even in this game targeted by the same optimization."

    • The driver apparently detects "crysis.exe" and inflates performance metrics by offloading processing, whereas renaming the executable to "crisis.exe" gives realistic performance scores. Please RTFA before replying.

        To me at least that reads as "it cheats in 3dmark but you catch it red handed if you benchmark with a game."

            The issue is that the driver treats different games differently, based on filename. Some get this boost and some don't. Whether you put 3DMark into the boosted or unboosted category, its results will be indicative of some games and not of others.

      That was my first thought, too.

      Here's the thing, though: They took 3DMarkVantage.exe and renamed it to 3DMarkVintage.exe, and much of that offloading was dropped. So this isn't a general-purpose optimization, which would make sense -- it's a targeted optimization, aimed at and enabled specifically for a benchmark, in order to get higher scores in said benchmark.

      It reminds me of the days when Quake3.exe would give you higher benchmarks, but worse video, than Quack3.exe.

      • They should remarket it as "application-targeted profiles" and sell it as a optimization feature.

        • No, they should either target behaviors, rather than executables, or make these available for teh application to request. Or they should improve the overall performance for everything -- starting with, oh, making a better chipset.

          Targeting specific executables, even if they do end up improving the performance of specific games, has the effect of raising the barrier of entry to that market -- I mean, it's hard enough to optimize a game engine without having to develop a business relationship with Intel.

    • Not so, an integrated GPU is simply a (often low power) GPU which uses the system's RAM instead of it's own RAM. Because system memory buses are usually much much slower than the ones included on dedicated graphics cards, and because the IGP shares the bandwidth with the CPU, the IGP is in turn relatively slow.

      There's not (normally) anything to do with using the CPU to do graphics computations.

    On the one hand, a mechanism that uses the CPU for some aspects of the graphics process seems perfectly reasonable(whether or not it is a good engineering decision is another matter, and would depend on whether it improves performance under desired workloads, what it does to energy consumption, total system cost, etc.), so I wouldn't blame intel for that alone.

    On the other hand, though, the old "run 3Dmark, then run it again with the executable's name changed" test looks pretty incriminating. Historically, that has been a sign of dodgy benchmark hacks.

    In this case, however, TFA indicates that the driver has a list of programs for which it enables these optimizations, which includes 3Dmark, but also includes a bunch of games and things. Is that just an extension of dodgy benchmark hacking, taking into account the fact that games are often used for benchmarking? Or is this optimization feature risky in some way(either unstable, or degrades performance) and so only enabled for whitelisted applications?

    If the former, intel is being scummy. If the latter, I'm not so sure. From a theoretical purist standpoint, the idea that graphics drivers would need per-application manual tweaking kind of grosses me out; but, if in fact that is the way the world works, and intel can make the top N most common applications work better through manual tweaking, I'm can't really say that that is a bad thing(assuming all the others aren't suffering for it).

    Just look at the pics. Changing the name of the executable changed the results dramatically. The driver is apparently detecting when it's running a 3DMark (or some other specific apps) and switches to some other mode to boost its scores/FPS markings.

      But see also Intel's response on page 2:

      We have engineered intelligence into our 4 series graphics driver such that when a workload saturates graphics engine with pixel and vertex processing, the CPU can assist with DX10 geometry processing to enhance overall performance. 3DMarkVantage is one of those workloads, as are Call of Juarez, Crysis, Lost Planet: Extreme Conditions, and Company of Heroes. We have used similar techniques with DX9 in previous products and drivers. The benefit to users is optimized performance based on best use of the hardware available in the system. Our driver is currently in the certification process with Futuremark and we fully expect it will pass their certification as did our previous DX9 drivers.

      And the rest of page 2 indicates that offloading some of the work to the CPU does, for certain games, improve performance significantly. Offhand, this doesn't necessarily seem like a bad thing. Intel is just trying to make the most out of the hardware of the whole machine. Also, one would also do well to bear in mind that the GPU in question is an integrated graphics chipset: they're not out to compete against a modern gaming video adapter and thus have little incentive to pump their numbers in a synthetic benchmark. Nobody buys a motherboard based on the capabilities of the integrated graphics.

      The question that should be asked is: What is the technical reason for the drivers singling out only a handful of games and one benchmark utility instead of performing these optimizations on all 3D scenes that the chipset renders?

      • by Guspaz ( 556486 )

        It makes sense; you'd only want to perform these optimizations in games where you're significantly GPU bound. CPU-heavy games, such as Supreme Commander, are probably better off spending the CPU time on the game itself.

        I'd see this as more laziness than anything else; it's easier to just hard-code in a list of GPU-bottlenecked games than it would be to actually have your driver auto-detect if there is idle CPU time that could be better spent on offloading.

    Intel fully admits that the integrated chipset graphics aren't that great. They freely admit that they offload rendering to the CPU in some cases. This isn't a secret.

    • I think GAMES is the operative word here. A benchmark shouldn't be targeted in such a fashion.

      To be fair, I'm pretty sure that Intel has made the highest-performing chipsets for Intel processors for quite a long time now, occasionally competing with Nvidia (who recently gave up). The other makers like VIA and SiS never had chipsets that worked as well as Intel's. Of course, this is for chipsets which don't have built-in graphics.

  • I'm seeing a potential other side to this that doesn't seem be being explored (unless I've missed something) -- if the optimizations are specific to .exes listed in the driver's .inf file, has anyone tried adding other games to the list (or alternately, just renaming another executable to match one in the list)?

    It would seem like an interesting turn if the optimizations are generic, but only enabled for games/applications that Intel has spent time testing them on.

    You'd think you'd have logic in the GPU that could determine when a certain load was being achieved, certain 3D functionality was being called, etc., and offload some work to a multicore CPU if it was hitting a certain performance threshold (as long as the CPU itself wasn't being pounded...but most games are mainly picking on the GPU and hardly taking full advantage of a quad core CPU or whatever). That makes a degree of sense...using your resources more effectively is a good thing. If that improves your performance scores, well...so what? It measures the fact that your drivers are better than the other card's drivers. That seems like fair play, from a consumer's standpoint. If the competitors can't be bothered to write drivers that work efficiently, that's their problem. Great card + bad drivers = bad investment, as far as I'm concerned. That's the real point of these benchmarking tests, anyway. It's just product marketing.

    But trapping a particular binary name to fix the results? That's being dishonest to customers. They're deliberately trying to trick gamers who just look at the 3DMark benchmarks into buying their hardware, but giving them hardware that won't necessarily perform at the expected level of quality. I generally stick up for Intel, having worked there in the past as a contractor and generally liking the company and people...but this is seriously bad form on their behalf. I'm surprised this stuff got through their validation process...I know I'd have probably choked on my coffee laughing if I were on that team and could see this in their driver code.

    Why do they keep trying it? The mind boggles.

    I would have thought by now that a standard tool in the benchmarkers repertoire was a tool that copied each benchmark exe to a different name and location and launched that, followed by a launch with the default name; and that the more popular benchmarks had options to tweak the test ordering and methodology slightly to make application profiling difficult.

    Just compare performance of gf285/295 v. radeon 4870/5870 (any review) in 3DMark and in games. In 3DMark Vantage nVidia cards have close to 50% advantage while in real games radeons sometimes score higher.
