AMD today quietly launched a trio of new graphics cards specifically intended for OEM builders, including an entry-level card that you could save up for with nothing more than a paper route. It's the Radeon HD 6450, a budget card priced at about $55 and built around AMD's lower-end Caicos chip with 160 stream processors, a 64-bit memory interface, and support for both GDDR5 and DDR3 memory.
Other specs include an engine clock of 625-750MHz, 512MB-1GB of memory (GDDR5 clocked at 800-900MHz and DDR3 clocked at 533-800MHz), 200-240 GFLOPS single precision compute power, 8 texture units, 16 Z/Stencil ROP units, and of course DirectX 11 support. AMD's intention here is to provide OEMs with an affordable alternative to slower onboard graphics.
Also new from AMD are the Radeon HD 6570 and 6670 cards. Both of these are based on AMD's Turks chip and come with 480 stream processors and 512MB-1GB of GDDR5 memory on a 128-bit memory bus. The slower-clocked 6570 runs at 650MHz (GPU), while the 6670 runs at 800MHz.
