Sunnyvale, California-based AMD is now expected to unveil its new Socket 939 platform and processors in PGA939 packaging on the 1st of June, 2004, after a number of setbacks, according to some sources. Earlier this year several dates were named for introduction, including, the 29th of March and the 25th of May, 2004.
AMD Athlon 64 processors with 939 pins will integrate 512KB of L2, only a half of the size incorporated into today’s 754-pin chips, but will benefit from very efficient dual-channel memory controller that is likely to decrease the impact of cut-down cache and even improve performance of 939-pin chips over 754-pin processors with 1MB on-die secondary-level cache, which is why CPUs in different types of packaging will not have similar model numbers at equal clock-speeds. The AMD Athlon 64 FX parts will continue to have 1MB of L2 after the transition to Socket 939.
