We've seen Nvidia's GeForce GTX 280 from just about every angle, and now it's the turn of AMD's own next-gen cards. The people at VR-Zone have found pictures of a Radeon HD 4870 with its cooler on, while the Bit-tech team was lucky enough to peek under the cooler of a Radeon HD 4850.
Starting with the faster card, the 4870 has a dual-slot cooler quite similar to that of the old Radeon HD 2900 XT, with the same hamster wheel-style fan and rounded edge. The card itself looks fairly long, and it has two PCI Express power connectors—one more than the Radeon HD 3870, suggesting a higher power envelope. Nevertheless, AMD has outfitted the 4870 with the two CrossFire bridge connectors necessary for three- and four-card multi-GPU operation.
Bit-tech's photo set tells us a little more about the new RV770 graphics processor. Judging by how it looks next to the Radeon HD 4850's PCI Express x16 connector, the RV770 is significantly larger than the current RV670, and it may be about as big as Nvidia's G92—even though the latter is based on a 65nm process rather than 55nm. The 4850 has only one power connector, and it will apparently feature a single-slot cooler like the Radeon HD 3850.
