AMD Updates Athlon 64 Line with New Socket
Advanced Micro Devices on Tuesday released its first processors to use its "Socket 939" technology. Offering faster HyperTransport speeds, the new chips come with a substantial price premium.Advanced Micro Devices Inc. on Tuesday released the first 64-bit Athlon processors to use its "Socket 939" interface. Offering gains in HyperTransport performance, the updated chip comes with a new chipset and a substantial price delta over previous chips. AMD introduced four new processors: a new 939-pin variant of its Athlon FX family, the Athlon 64 FX-53; and three new Athlon 64 chips, the 3800+, 3700+ and 3500+. Although AMDs "model numbers" imply a consistent architecture, the opposite is true. All four vary in the number of pins used, as well as the cache size and width of the memory bus. Since AMDs Athlon 64 and Opteron architecture include an integrated memory controller, the company often redesigns the entire chip to enable faster memory speeds.
For example, two of the new chips, the Athlon 64 3500+ and 3800+, feature the new Socket 939 infrastructure, which intrinsically supports a 128-bit-wide memory interface to unbuffered DDR400 memory.
