Our friend Coolaler has scored some pictures of an upcoming RV670 based graphics card over at his forum and it looks like MSI is the first ones to drop the ball. Although we doubt it'll be called the MSI RX2600XTX, but we could be wrong. If so, the RV670 will replace the current Radeon HD 2600 XT or at least become the XTX version, which is a highly unusual move.
The card itself is the size of a Radeon HD 2900 XT, but it has a single slot cooler and some funky copper heatsink cooler over the power regulation part at the rear of the card. It doesn't really look like a low noise cooler, but hopefully the card won't get too hot and thus the fan won't need to spin at full speed. This reference card features a 6-pin PCI-Express type power connector, however we wouldn't expect that this is needed on PCI Express 2.0 boards, since the RV670 supports PCI Express 2.0.
The RV670 features a 256-bit memory interface and the reference sample has 256MB of GDDR3 memory. The eight modules are from Hynix and are rated at 1.1ns or 900MHz, although on this specific card the memory is only clocked at 600MHz, or 1.2GHz effectively. The GPU which is AMD's first 55nm part is in this case clocked at 600MHz.
Otherwise there isn't all that much that stands out, the card has dual DVI connectors and these will most likely work with AMD's HDMI adapter, two CrossFire connectors and a TV-out port. If this new GPU doesn't run any hotter than the current Radeon HD 2600 XT we should be able to see some dual GPU cards based on the RV670, we can't wait.
