AMD Radeon HD 4550 4350
AMD early Tuesday took its Radeon HD 4000-series chipsets into ultra budget territory with two video cards that promise better performance than their prices would suggest. The Radeon HD 4550 and Radeon HD 4350 have just 80 stream (effects) processors versus as much as 800 for the Radeon 4800 series but are still capable of full DirectX 10.1 and current OpenGL 2.x effects, rendering them some of the least expensive cards capable of their more advanced visuals. The new chipsets are also some of the only ones of their type to have 7.1-channel audio pass-through over HDMI and the option of DisplayPort.

Radeon HD 4870 X2 in July
AMD is preparing a dual-chip version of its Radeon HD 4870 card within a matter of weeks, say board designers. The 4870 X2 would be a direct sequel to the 3870 X2 and would once again graft two high-end graphics processors on to one card with a similarly doubled amount of memory; the 4870 edition would be the first home card to carry 2GB of total memory. Past cards have also been underclocked slightly from the single-chip version to avoid overheating.

AMD Water Cooled 4870
AMD is gearing up for the launch of a special Radeon HD 4800 card designed explicitly to push past the GeForce GTX 280 in sheer performance, according to a new leak. The unnamed hardware would use the extra energy headroom of the card along with a custom water cooling system to clock the card well above the company's best individual card, the 4870: the core would reach 950MHz or more, while the video memory would be pushed to a 1.2GHz actual speed.
