The ATI Radeon HD 4600 series has just begun shipping to retail, and the chances are pretty high that it’s the only graphics card you’ve ever seen that delivers HD multimedia while consuming less power than a standard light bulb.
The ATI Radeon HD 4600 series — comprised of the Radeon HD 4670 and Radeon HD 4650 cards — uses the same technology as the ATI Radeon HD 4800 series, including support for latest DirectX 10.1 games. The difference: it’s designed to be more affordable.
The ATI Radeon HD 4670 is available now with a frame buffer of 512MB GDDR3 memory for USD $79. A 1GB DDR3-based variant is scheduled to ship later this month. The ATI Radeon HD 4650 features a frame buffer of 512MB GDDR2 memory and is expected to be available later in the month for USD $69.
The ATI Radeon HD 4670 and ATI Radeon HD 4650 graphics cards feature AMD’s TeraScale graphics engine, with 320 stream processing cores and are based on AMD’s second-generation 55nm process. The result is that games like Crysis actually become playable.
