AMD is planning the quad-core Altair K8L desktop processor along with a couple of processors codenamed Antares, Arcturus and Spica.
Antares will feature only two cores with each 512KB L2 cache and connected to 2MB shared L3 cache. Antares will have HyperTransport 3.0 clocked at up to 4.2GHz and it will be shipped in the third quarter of 2007.
Arcturus is the same processor as Antares but with lower core and bus clock speeds and no L3 cache or no shared cache. The bus will run at 3.4GHz and the cores between 2.1GHz and 2.3GHz compared to 2-2.9GHz for Antares. Arcturus will consume 65W while Antares will be available as 35W, 65W and 89W SKUs.
Arcturus will ship in Q4 2007, in the same quarter we can also expect the mono-core Spica.
