AMD has started revenue shipments of a limited quantity of Opteron 12-core server CPUs, with the launch coming on schedule – “later this quarter”. The 12-core CPU, codenamed Magny-Cours after the French Formula 1 circuit, will fit into the elongated Socket G34. Essentially, Magny-Cours is an MCM version of six-core Lisbon, which itself is a refined version of the earlier six-core Istanbul CPU.

The Opteron 6000 series will service TDPs of 85W to 140W, with clock speeds between 1.70 GHz and 2.4 GHz. While the clock speeds may sound low – 2.4 GHz over a full 12 cores is some serious processing power.

Unfortunately for AMD, Intel have two devastating range of server CPUs upcoming. The 32nm six-core/twelve-thread Gulftown, which will work at immense frequencies, followed shortly by eight-core/sixtreen-thread Beckton CPUs. Beckton follows a similar strategy as Magny-Cours, with an MCM of 45nm Lynnfield, on an elongated LGA 1567 socket.

While AMD’s Opteron 6000 series leads in raw core count, it trails Intel significantly in both clock speeds and clock-for-clock architectural performance. However, AMD, like in the desktop arena, will not fight in the highest performance segment. A 12 core CPU is quite a product – and it will have its market, especially for largely multi-threaded tasks.

AMD is also expected to release eight-core variants of Magny-Cours, and six-core Lisbon CPUs.

Unlike Istanbul following on to Thuban (AMD Phenom II X6), Magny-Cours will not release as a desktop platform – mainly because of the requirement of a specific socket.
