AMD is said to be working on a new processor codenamed "Thuban", this chip will be the first six-core processor for desktop PCs. The AMD Thuban is expected in 2010.
AMD’s processor code-named Thuban is the company’s first desktop processor with six processing engines. The microprocessors will be compatible with socket AM3 infrastructure and will have integrated dual-channel PC3-10600 (DDR3 1333MHz) memory controller. It is very likely that Thuban processors will retain AMD Phenom II brand name as well as design of the code-named Istanbul chips for servers, thus, will feature 3MB L2 cache (512KB per core) and 6MB of L3 cache. The chips will be made using 45nm SOI fabrication process.
Thuban is a star in the constellation of Draco and it also means “dragon” in Arabian language. The new six-core chip should be compatible with existing AM3 infrastructure (and, quite possibly, even with AM2+ infrastructure with split power plane), it remains to be seen whether Thuban becomes a part of AMD’s current high-end desktop platform called Dragon, or will power the company’s next-generation Leo platform.
