AMD expected to unveil Radeon HD 7000 in December

AMD's upcoming 28nm graphics parts, set to launch under the family name Radeon HD 7000, aren't expected to appear until January - but sources claim that the chip maker is looking to build up some hype with a paper launch event in London next week.

AMD's Radeon HD 7000 family is expected to appear in January for high-end parts, February for cheaper models, March for lower-end parts and April for the entry-level hardware. While little is known regarding the technical details, leaked information suggests a 384-bit memory bus that would support up to 3GB of GDDR5 graphics memory on a card featuring a single graphics processor, and up to 6GB on a card with dual-GPUs.

Although AMD is keeping its cards close to its chest on this particular launch, unnamed industry sources speaking to Swedish tech site NordicHardware suggest that a press event to be held on 5th December will constitute a 'paper' launch of the hardware.

Built around a new generation of graphics processing technology - rather than a mere drop in process size - the Radeon HD 7000 series is expected to boost AMD's presence in the general-purpose GPU (GPGPU) computing stakes, winning back business lost to rival Nvidia in high-performance and technical computing markets.

The initial boards will, however, retain their traditional focus on gaming performance, with the initial high-end parts expected to retail in the US for around $500 each.
