AMD's Leo Desktop Platform Due in 2010

Last month, AMD confirmed that six-core 45nm Thuban processors were due for consumer platform. These new six-core desktop processors, along with AMD 890FX and 890GX core-logics, will form AMD's Leo platform. AMD has planned to release its Phenom II X6 CPUs in the second quarter 2010 which will collide with launch of Intel Core i9 Gulftown six-core processors as per X-Bit Labs.

AMD's 45nm six-core Thuban processors would be backward compatible with Socket AM3-AM2+ and will have integrated memory DDR3 1333MHz memory controllers. It's likely that AMD will take some design aspects of Istanbul chips for servers and thereby add 3MB L2 cache (512kb per core) and 6MB L3 cache. On the other hand, Intel's six-core Gulftown chips have 12MB L3 cache.

Intel's Gulftown would be compatible with Socket 1366 since it would be a follow up to the 32nm Westmere Core i7 family. With Hyper-Threading technology, these six-core chips would be capable of handling 12 threads at the same time.

AMD is yet to announce clock speeds of Thuban chips and its thermal design power rating.

To complement the prowess of AMD Phenom II X6 Thuban chips, AMD will release 890FX and 890GX chipsets. These chipsets are expected to bring features like support for Serial ATA-600, 14 SATA 2.0 ports and so on. According to market sources, both chipsets are expected to go in production in April 2010 and would be released the following month.
