AMD launches Radeon HD 5770, 5750
AMD's graphics label ATI today extended its next-wave hardware into the mainstream. The Radeon HD 5770 and Radeon HD 5750 scale back to a 128-bit memory bus and significantly fewer effects cores but still have the full DirectX 11 and OpenGL 3.x feature sets of the 5800 series as well as support for multi-display Eyefinity. They remain dual-slot cards but consume much less power at 108W peak for the 5770 and 86W for the 5750.
The 5770 as the range leader has half the cores of the 5870, at 800, but shares its 850MHz main clock and carries 1GB of 1.2GHz GDDR5 memory. The 5750 has 720 cores, a 700MHz main clock speed, and either 512MB or 1GB of GDDR5 memory at 1.15GHz.
In making the feature cuts, AMD says the expected selling price of a typical 5770 upgrade card should reach down to $159 even when new. The 5750 will cost either $109 or $129 for 512MB and 1GB versions respectively. Several card manufacturers, such as MSI, are expected to have cards available immediately; the 5700 line is also likely to ship through PC builders.
