DigiTimes says the launch of the AMD R600 GPU will either be at the end of March or at the beginning of April.
The R600, which will compete head to head against Nvidia's G80, is manufactured on 80nm node, supports DirectX10 and features DDR4, the Taiwan makers added.
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's G84 and G86 are expected at CeBIT next month.
