3DMark08 'Vantage' Review :wink:
from Extremetech.com
We have recently talked about the new 3DMark and its proprietary use of Vista and DX10 cards, but I would like us to step back and take a look at this bleeding edge benchmark that brings the most expensive systems to their knees. And we should see what the future of 3D gaming can be.

Here are some things to look for:
Introduction:
Benchmarking 3D graphics cards and CPUs for gaming is tricky business. Of course testing real games is the preferable method, but that can only tell you how well a certain piece of hardware runs the stuff that's out there today. You want to buy a graphics card that will be good at future games as well, right? Then there's the issue of how you testpre-recorded timedemos and built-in benchmark modes have the advantage of perfect repeatability and reliability.
Measuring frame rate over time during actual gameplay is a more accurate representation of the performance you can expect while truly playing games, but it carries with it the fallibility of each test not being exactly like the one beforevariance in performance may be the result of an imperfect tester, rather than true differences in the hardware you're testing.
3DMark has for years now filled a wholly different role than "real game testing." It's a synthetic benchmark, not a game, but it's made with some very game-like code. The scenes and graphics techniques represent the same kind of stuff games use. What's more, by not being a game, 3DMark can afford to be very future-looking.
The tests and graphics techniques in 3DMark are meant to represent what we'll see in games over the next year or two, not what's on the market right now. In this, it takes its biggest drawback (that it's not a real game and therefore does not represent real game performance) and turns it into its biggest strength (by using forward-looking graphics techniques it can give some insight into how graphics cards may perform in future games).
3DMark06 has gotten a bit long in the tooth, and no longer reflects this forward-looking approach. Even inexpensive graphics cards run it incredibly well, and many graphics techniques in modern games are beyond what are used in the benchmark. And so, after perhaps too long a wait, Futuremark has finally released their follow-up, 3DMark Vantage. Let's take a closer look at the new tests and scoring methods, and find out what the new version of the industry-standard benchmark means for us.
Major Changes
The first thing you'll notice about the new 3DMark is that it's DirectX 10 only, which means it's Windows Vista only. The other system requirements are pretty steep, but then again, this is supposed to be a forward-looking benchmark. The required CPU is a dual-core, equivalent to an Intel Core 2 Duo E6600 or Athlon 64 X2 6000. It will run with any DirectX 10 graphics card with at least 128MB of RAM, and there's no minimum system RAM requirement beyond that for Vista, but in our experience you'll want 2GB of RAM to avoid hard drive activity during the tests.
Futuremark has also changed the pricing structure. Now the free version only allows you a single benchmark run. If you want to run the benchmark more than once, you need to shell out $6.95 for the Basic Edition, which allows you to run a single "performance" preset (more on that later) as much as you want, but requires a network connection in order to view your results. If you want more, you can pay $19.95 for the Advanced Edition, which lets you run all four presets or any custom settings you desire, though you still need a network connection to view your results. For commercial use, there's the $495 Professional Edition that includes technical support, automated command-line scripting for batch testing, and the ability to view your results without going online.
There are other changes, too. Where there used to be a single default 3DMark setting (1280x1024 with no anti-aliasing or anisotropic filtering), there are now four "presets." These represent four different performance levels of graphics cards, and represent changes in resolution, AA/AF settings, texture resolution, shadow quality, shader complexity, and post-processing effects. The four presets are presented in the table below.

We're going to test a handful of recent and popular cards from Nvidia and ATI.
* ATI3870 X2, 3870, 3850
* Nvidia9800 GTX, 8800 GT, 9600 GT
We wanted to include the newer 9800 GX2 dual GPU card from Nvidia, but weren't able to because of power supply issues. We'll follow up in the future with more on the 9800 GX2.
Naturally, both companies released last-minute drivers to improve 3DMark Vantage performance. Nvidia's Forceware 175.12 is the driver of choice, and ATI released a hotfix with driver revision 8.471. The ATI driver, in particular, came with a few warnings about some potential gotchasyou have to reboot when enabling CrossFire, quad CrossFire X performance isn't what it should be, and so on.
Naturally, the release of a new 3DMark is just the beginning of a driver and product battle between graphics companies that won't be settled anytime soon. In the short term, we can expect each new driver to improve 3DMark performance in some way. In the long term, new products will tout new 3DMark records, and driver releases for the first few months after a new product's release will offer 3DMark gains. That's just the way of it. Fortunately, improving 3DMark performance will often lead to performance gains in other DirectX 10 games.

The result is measured in Operations Per Second, where one physics "step" of one "world" (pair of gates) is considered one operation. Remember that the CPU tests represent only a part of the overall 3DMark scoreat most 25% on the Entry setting, and only 5% on the Extreme setting.

What It All Means.... 
Now that we have this mountain of information at our disposal, what does it all mean? Frankly, right now, not as much as you would think. The problem with a new release of 3DMark is that it's a very difficult and forward-looking test application that has a ton of importance placed upon it by the industry. In 46 weeks, if you ran all these tests again, you could almost guarantee different performance thanks to inevitable driver optimization.
Still, we can take away some important info. The PhysX cards, when utilized heavily as they are in the second CPU test, can outperform even a high-end CPU, but not as much as you would think. It's not a factor of ten, or even a factor of two. With the limited support and sales of PhysX cards so far, and future CPUs like Nehalem surely offering better performance at these tasks, it's hard to see this benchmark making the case for that hardware. However, the addition of a PhysX card can improve the Entry preset 3DMark score by 5% or so (its influence tapers off on higher settings), so make sure you know if the card is present when comparing numbers. We plan to test without it, unless specifically noted.
It's also very interesting to look at the specific feature tests, where the cloth physics and particle rendering tests are dominated heavily by Nvidia cards. Is this a difference in hardware capabilities, inherent to the GPU architectural designs? Or will we see ATI catch up with driver updates?
3DMark Vantage's GPU tests makes use of a fair amount of GPU-generated data, which is a difficult situation to deal with when developing CrossFire and SLI drivers. Watching 3DMark numbers for multi-GPU scaling may be a good indication of how we can expect many DX10 titles to scale on dual-GPU cards and multi-GPU setups.
Finally, we see that even some pretty dramatic driver optimizations won't allow current hardware to run the new tests at what would be acceptable frame rates in a real game, unless you choose the Entry setting where everything is greatly simplified. This is actually good newsit creates a work load for graphics cards that will truly show what new hardware is capable of, even when many modern games may not. It cements 3DMark Vantage as a very forward-looking test.
It goes without saying that 3DMark Vantage is not a real game, and shouldn't be treated as such. We care primarily about graphics performance in games, not synthetic benchmarks, and 3DMark scores should never be used to replace real game benchmarks. However, the very forward looking nature of the tests, and its propensity for using graphics features that hammer GPUs in ways current games don't, make it a very useful additional tool in evaluating GPU performance. At some point in the future its relevance will be diminished, but now, in the early days when increasing 3DMark performance often means increasing real game performance, it's a good benchmark.
There's always a certain amount of controversy about a new 3DMark, and we don't expect less this time around. Why no DX 10.1 support, for instance? (Futuremark says 10.1 was available too late in the development of 3DMark Vantage to incorporate.) Why support the PhysX cards when so few games do, and don't look likely to in the future? (Frankly, it doesn't make that big a difference.) We expect ATI and Nvidia each to, at some point, call the other out for driver shenanigans when they don't like the other's 3DMark scores. This stuff goes with the territory, and our job is to keep an eye on the situations as they develop and deliver to our readers as much clear, accurate information as possible.
