Advanced Micro Devices on Monday introduced a low-power variant of its six-core Opteron server chip, which is codenamed Istanbul.

The Opteron 2419 EE draws up to 40 watts of power, which almost equals the lowest power drawn by AMD's existing quad-core line of Opteron server chips codenamed Shanghai. The new chip provides 30 percent more performance compared to quad-core Opterons in the same power band, the company said.

The improved performance could help cut energy costs and consolidate servers in data centers, AMD said.

The processor runs at a speed of about 2.0GHz and includes 512KB of L2 cache per core, with 6MB of common L3 cache.
