The Numbers Don't Lie
In the end, all this hardware amounts to one hell of a fast machine. And not just in theory—as in, next year when such and such comes out, this rig’s power will be evident (although we do admit that some software optimizations will be needed).
In the here and now, we routinely saw performance benefits with many of today’s applications.
For comparison, we put Dream Machine against our standard zero-point 2.67GHz Core 2 Quad Q6700, GeForce 8800 GTX box—and DM pretty much flattened it with double- and triple-digit spreads. While a sub-3GHz quad-core box might sound quaint today, we’ll remind you that our zero-point PC actually gave a new 3.5GHz Core 2 Duo gaming PC that we reviewed in August a pretty good drubbing. So it’s not exactly a slouch.
Still, perhaps that machine’s not the most telling measure of the Dream Machine’s fury. For a more worthy contender, we turned to the CyberPower Gamer Ultimate SLI Quad PC that we reviewed in July. With its 4GHz Core 2 Extreme QX9770 CPU, 4GB of DDR3, and a pair of GeForce 9800 GX2 cards, the system rocked all those that came before it and we knew this mean machine would be difficult to overcome.
But DM did it. At least in some tests. We saw Dream Machine rip past the CyberPower box in both Premiere Pro CS3 and ProShow Producer by 23 and 36 percent, respectively. That’s nothing to turn your nose up at. In other tests, Dream Machine did well, but not spectacularly. In Photoshop CS3— not exactly the most threaded application in the world—Dream Machine scored a near tie with CyberPower, taking just two more seconds to complete our test. Since Photoshop doesn’t exploit our second proc, and honestly, barely pushes a single quad-core CPU to the edge, this is about what we’d expect from PCs that operate at the same clock speed.
In our MainConcept benchmark, DreamMachine was about 10 percent slower. Why? The encoder that’s used in MainConcept Reference is license-limited to single-processor support. Multi-processor support is available only with the professional version, which on the Dream Machine cut the encode time in half, by the way.
In our Unreal Tournament 3 Direct X 10 benchmark, DM’s pair of Radeons didn’t disappoint, cranking out 145 fps. Mind you, our normal benchmarks are designed to measure system-level performance. They’re not meant for pure GPU analysis—thus, we don’t run with antialiasing or massive amounts of filtering enabled. Still, we saw almost double the numbers that a pair of GeForce 8800 GTX cards could produce and 12 percent more than quad SLI cards mustered. With AA and aniso cranked up, the Radeons really start to strut their stuff. When we were still deciding what cards to use in DM, we also ran a GeForce GTX 280 in 3DMark Vantage. A single GTX 280 belts out 9,668 in the GPU tests—very impressive. But not as impressive as the 19,014 that our two Radeons put out. For all you 3D Vantage fans, Dream Machine’s overall score was 20,539. Not bad.
Of course, this leads us to our most heartbreaking test: Crytek’s Crysis. We expected the Radeons to crush everything in this one benchmark, but they just didn’t perform. Why? First, as we mentioned earlier, our system benchmarks are designed to reflect normal system use, not act as GPU tests—AA is not enabled nor is tons of filtering. However, we do run at an all-out 1920x1200 resolution. That’s enough to make most systems whimper. While CyberPower’s Quad SLI rig spit out 55 fps, DM was chugging along at 26 fps—about the same performance we got from two GeForce 8800 GTX cards. What the frak? We got ATI on the horn and learned that the likely culprits were driver and OS optimizations—or rather, lack thereof. ATI didn’t expect to make the cards public for several more months. The company has done some optimization for the X48 chipset, but Skulltrail’s 5400 chipset wasn’t on the top of the list. The company is still sorting out some issues with how Windows Vista handles ATI’s AFR rendering. So this is what we’re talking about when we say future performance will come through improved drivers.
But what choice did we have? We sure as hell weren’t going to participate in this silly battle between the CPU and GPU camps. As true believers in pure PC power, we weren’t going to betray that mission statement in our 10th anniversary issue—thus, this machine marks our commitment to having it all.
