ATI Radeon HD 3870 X2 Graphics Driver
In truth, it's a pretty effective approach and seems to be the only viable option for making the most of the ever-burgeoning transistor counts that shrinking silicon production technology has enabled. The same sort of thinking has been creeping into graphics technology of late, too.
Reality Check When these multi-GPU solutions work correctly, the performance gains can be truly spectacular. And yet, SLI and Crossfire have utterly failed to gain any real traction in the market. Take the recent Steam surveys from Valve, for example.
Indeed, AMD itself concedes that in terms of multi-GPU performance scaling, it has no advantage over a pair of individual Radeon HD series cards running in tandem courtesy of Crossfire. Surprisingly, however, ATI has since managed to crank up the clockspeeds.
Memory speeds, by contrast, have taken a bit of a dip, down from 2. Don't worry, though - we won't be taking their word for it. So, along with MB of graphics memory, it's got the same not-very-old shader units and 16 texture and render output units in each surprisingly compact 55nm chip. They also pack the most advanced 3D feature set on the planet, thanks to the Series' unique ATI Radeon HD 3870 X2 Graphics for DirectX For now, there are no games written for DirectX Power hungry What's not up for debate is the size of the HD X2.
This is one big, butch, beefy board.
But thanks to the utterly epic cooling solution required to keep those high-clocked GPUs in check, the X2 is much thicker. Unsurprisingly, it also guzzles more gas - 60 more Watts than an GTX under load.

ATI Radeon HD 3870 X2 Graphics It's an imposing card, therefore, with a frankly terrifying on-paper specification. But does it deliver the pixel-pumping goods in practice? Yes, but with a large, storey neon-lit caveat, which we'll come to in a moment. The single-card implementation of Crossfire could have easily transformed into big product delays and an overall less appealing product down the line.

But AMD has proven itself this time, successfully launching the Radeon HD X2 on schedule, and perhaps even more important than that, having actual products on retail shelves immediately. However, because the X2 is meant to be a 'transparent' single card solution, it is still possible to use two of these graphics cards in Crossfire mode.
Meaning that with the proper drivers, a quad-Crossfire system becomes a possibility. Even before testing the X2, we could imagine the performance of two Radeon GPUs put together would be quite good, but as is the case with standard dual-card SLI or Crossfire, we also expected it to suffer from the same variance depending on the game run. And indeed, the performance of the Radeon HD X2 turned out to be quite close to that ATI Radeon HD 3870 X2 Graphics you will see in our benchmarks.
But the brilliant part about the new Radeon design is that it doesn't rely on drivers or a specific chipset to work using the two GPUs in a single board.
