From our front-page news:
When AMD launched their HD 4000 series last month, good things happened. Both cards (HD 4850, HD 4870) debuted at fantastic prices, and competed severely with NVIDIA's recent offerings. It was the first time in a while we saw such a thing. Well, what could top that launch might be the X2 cards, starting off with the HD 4870 X2.
Our friends at the Tech Report have scored themselves an engineering sample and put it to some early tests. Compared to the older HD 3000 X2 cards, not much has changed in way of board layout, so it all lays with the performance now. Not surprisingly, the card delivers.
Interestingly, the card not only manages to out-perform SLI'd GTX 280's in many tests, the performance between the X2 and dual HD 4870's in Crossfire deliver almost identical performance. I might have to change my opinions from last week on the GeForce GTX 280, with new performance numbers like these. By the looks of things, it will all come down to price. Too bad we'll have to wait a bit longer to see what those will be.

Although this product's code name, R700, follows a naming convention similar to past high-end Radeon GPUs, it's not really a new GPU at all. Instead, it's just two RV770 graphics processors having a party together on one PCB, pretty much like the Radeon HD 3870 X2 was in the last generation. In fact, the new X2 looks an awful lot like the old one at first glance.
