AMD To Release Magny-Cours Chips On March 29

Opteron server clock speed

Additionally, Sunnyvale, Calif.-based AMD plans to release the first processors from the upcoming Opteron 4100 series -- code-named Lisbon -- on May 4, according to industry sources. The Opteron 4100 series includes quad-core and six-core processors optimized for two-socket server and workstation configurations.

With its late March release, Magny-Cours will come on the heels of AMD archrival Intel's launch of its first 32-nanometer Xeon processors later this week. Intel has included six-core server chips in its initial Westmere-class Xeon offering -- matching AMD's last major Opteron launch of its own six-core Istanbul-class chips in June 2009 for the first time with a similar chip architecture called Nehalem.

Magny-Cours is a 45nm processor that marks the end of the line for AMD's long-standing, DDR2-designed Socket F, which has supported successive generations of dual-core, quad-core and six-core Opteron chips since the CPU socket's introduction on Aug. 15, 2006. The Opteron 6100 series will be introduced as part of a new server/workstation platform code-named Maranello and a new socket, Socket G34, that supports four DDR3 channels.

The Lisbon-class processors are built for another platform entirely, code-named San Marino, that utilizes Socket C32.

Notes: All Opteron 6100 series processors are 45nm SOI parts with 512KB of L2 cache per core and 12MB of L3 cache (19.6MB total cache for 12 core parts, 7.1MB total cache for eight-core parts). The I/O bus frequency for all processors is 1.8GHz and maximum I/O bandwidth is 102.4GB/s, with DDR3-133 support of up to 42.7 GB/s memory bandwidth per CPU.
