Opteron

Opteron is a 64-bit microprocessor from Advanced Micro Devices (AMD), which is offered in several versions with different clock frequencies. The Opteron has the most diverse codenames. Thus, the Opteron 800 series' codename is Athens, that of the Opteron 2xxx and 8xxx with K10 core is Barcelona and that of the Opteron 1xxx is Budapest. In terms of integration density, the Opterons belong to GLSI technology with a structure width of 90 nm.

In version 240, the Opteron has a clock frequency of 1.4 GHz, in version 242 one of 1.6 GHz and in version 244 the highest with 1.8 GHz. The Opteron has two 64 kilobyte( KB) level 1 caches and a 1 megabyte( MB) level 2 cache. The data transfer rate required for fast memory transfers is provided by a DDR SDRAM controller. In addition, the Opteron offers an enhanced 3D/ multimedia instruction set and full compatibility with 32-bit applications. It can handle 32-bit Windows/ Linux software used in desktops and smaller servers, as well as 64-bit programs for high- performance servers.
