R600 tops out at a record-busting 12.4-inches in length. ATI will have two SKUs of the R600 at launch, the XTX which features 1GB of DDR4 RAM and the R600XT with a mere 512MB of GDDR3 -- weak sauce, we know. The XTX version comes in retail and OEM versions and it's the OEM one (pictured) that really gets outlandish, with the 12.4-inch length and 270W of power consumption. The retail XTX cuts it down to 9.5-inches and 240W, while the weaker XT matches those specs. A little bit down the road, ATI will follow these up with the R600XL which will be cheaper and hopefully less demanding. Just for a frame of reference: NVIDIA's 8800 GTX was deemed outlandish with its longest-ever 10.4-inch length and beefy 165W power requirement. How much bigger are these things going to get? Oh, that's right, once they get outside our PCs there just won't be any stopping 'em.
