On Monday Advanced Micro Devices (AMD) Company is making good on its 45nm roll-out plans -the company released five new low-power Shanghai-class Opteron processors and two more special edition chips.

AMD's Shanghai Opteron lineup include both five new low-power 45-nm versions for servers, as well as a pair of high-end chips designed for 105-watt power envelopes.

The two new special edition Opterons, designated SE, become the top parts in their respective stables. Both are 2.8GHz, 45nm quad-core Opterons slotting into the 105W thermal envelope -- the Opteron 2386 SE is priced at $1,165 and the Opteron 8386 SE at $2,649.

The latest chips, all quad-core, cover two-, four-and-eight socket servers and can plug into the same motherboards running AMD's older 65-nm Opterons. With the new technology of AMD chips customers can get a speed boost without replacing hardware.

For two-socket boxes, the Opteron 2372 HE part runs at 2.1 GHz and costs $316 in 1,000-unit quantities. The 2374 HE runs at 2.2 GHz and costs $450. And the 2376 HE runs at 2.3 GHz and costs $575. For bigger boxes, there's an 8374 HE running at 2.2 GHz that costs $1,165 and an 8376 HE running at 2.3 GHz that costs $1,514. The topper 2386 SE part for two-socket servers runs at 2.8 GHz and costs $1,165, while the 8386 SE part for four-socket boxes (running at the same speed) costs $2,649.

According to AMD, the latest products deliver 44% better performance than previous generation Opterons of the same type.

Brent Kerby, Senior product marketing manager for AMD quoted that a BIOS upgrade is needed for the new chips.
