AMD will start supplying 65nm CPUs in December 2006, first for the OEM market. This will affect Athlon 64x2 4200+ (2.2Ghz/512KB L2 x2), Athlon 64x2 4400+ (2.2GHz/1MB L2 x2), Athlon 64x2 4600+ (2.4GHz/512KB L2 x2) and Athlon 64x2 4800+ (2.4GHz/1MB L2 x2) with a new 65nm core code-named Brisbane. It will be manufactured using Strees Memorization and 3rd Strained Silicon technology, enhancing electronic capability by up to 42%, enabling lower power consumption. Brisbane is not to replace the Winsor cores and they will both have their place in the market. The higher-end models, such as Athlon 64x2 5000+ (2.6GHz/512KB L2 x2), Athlon 64x2 5200+ (2.6GHz/1MB L2 x2), Athlon 64x2 5400+ (2.8GHz/512KB L2 x2), FX-62(2.8GHz/1MB L2 x2) and FX-64(3.0GHz/1MB L2 x2) will still remain on 90nm process during this transition period. The low-priced Semprons will go into the 65nm process at the second half of 2007, named Sparta.
