DigiTimes, citing inside sources, says the release of the ATi R600 will come in March or April. Good news for all you ATi fans. The R600 will come in four models targeting different market segments. The high-end part will have power consumption of 270 Watts and target OEM partners, such as Dell, sources said. Earlier reports listed Taiwan Semiconductor Manufacturing Company (TSMC) as the foundry partner. The other models (including XTX, XT, XL) will target channel markets and will have a power consumption lower than 240 Watts, added the sources. Nvidia, on the other hand, may launch its G84 and G86 at the upcoming CeBIT show, with the parts targeting the mid-range and entry-level markets, respectively, the motherboard makers said.

We've heard a number of rumors about AMD's upcoming R600 graphics processor over the past few weeks, and now the folks at The Inquirer claim to have the scoop on its core and memory speeds. The Inq says the top-of-the-line R600 model will have a sizzling core clock speed of around 800MHz with GDDR4 memory running at somewhere between 1GHz and 1.1GHz. As if that weren't fast enough, they say the R600 will have an Overdrive mode similar to the one in current Radeons that will allow users to squeeze a few extra MHz out of the card with AMD's blessing. With overdrive enabled, the R600 will reportedly be able to hit 880MHz core and 1.2-1.3GHz memory speeds.
