Benchmark Results: Crysis 64-bit

Core i7: 4-Way CrossFire, 3-way SLI, Paradise?

We just had to try the 64-bit version of Crysis—and we’re yet again presented with mind-blowing results.

Let’s start this round off by talking about resolutions. Nvidia’s GeForce GTX 280 demonstrates beautiful scaling at 1900x1200 on both the Core 2 Extreme and Core i7 systems, with Core i7 showing off some impressive performance gains in what we thought would be a test dominated by the fastest graphics processor. Nevertheless, ratcheting up to two and three GTX 280s buys significant gains. But 2560x1600 is a different story entirely. In fact, we’d call the discrepancy between the two resolutions a full-blown disaster. One, two, three cards—it doesn’t matter. You’re looking at unplayable frame rates across the board.

Once again, Phenom X4 runs out of breath with a single Radeon HD 4870 at 1920x1200. Beyond that, you can’t expect much extra, even with a jump to four GPUs.

Core i7 965 Extreme and Core 2 Extreme QX9770 perform very similarly with Radeons under the hood. They actually both peter out and yield fairly poor scaling from two RV770s to four. And even at 1900x1200, we’d hesitate to call the performance of four GPUs playable. This doesn’t bode particularly well for the addition of anti-aliasing.

For the first time in our testing so far, we’re seeing ultra high-end platforms kicked to the floor.

We’ll take the resolution route again here. Nvidia’s GeForce GTX 280 again yields picture-perfect scaling at 1920x1200, even giving us the chance to enjoy quasi-playable frame rates with 3-way SLI cranking away. We also see a reason to get excited about Core i7. As Fedy pointed out in our Nehalem preview, Core i7 supports macro-ops fusion in 64-bit mode, so there’s a fair chance that we’re getting a performance boost from this enhancement given the sizable frame rate increase.

But then we shift to 2560x1600 and performance not only tanks—it actually gets worse as you add graphics cards. On the Core 2 Extreme, the benchmark fails entirely.

AMD’s Radeon HD 4870s fare better across the board. Unfortunately, they’re never quite fast enough to serve up playable frame rates in this fast-paced first-person shooter. Perhaps the most interesting performance inflection is the single Radeon HD 4870—a 512 MB board. Given its memory handicap, frame rates linger in the single-digit range. The Radeon HD 4870 X2 adds a second GPU, but more important here is the shift to 1 GB of GDDR5 per processor, which multiplies performance by four.
