Advanced Micro Devices Inc. on Tuesday will introduce a new 400MHz front side bus, its fastest FSB yet, along with possibly its highest performance Athlon XP 3200+ processor, according to sources in industry.
An AMD spokeswoman declined to comment. Until now AMD's fastest FSB has been 333MHz, which is a frequency match for DDR333 memory.
The new 400MHz FSB will be a match with the new generation DDR400 memory now ramping up in the market.
Third party vendors, including Nvidia Corp., Silicon Integrated Systems and Via Technologies Inc., have already announced chipsets supporting AMD processors with a 400MHz FSB and DDR400 memory.
Intel Corp. next week is slated to unveil an even faster quad-pumped 800MHz FSB with its new 865 Springdale chipset for desktop PCs.
Intel already introduced the 800MHz FSB and the 875 Canterwood chipset for workstations and very high performance PCs.
AMD is expected to counter Intel's faster FSB by claiming this is only one parameter in overall system performance.
Just as the two rivals battled over processor clock speed frequency, the two are set to square off on system performance vis-a-vis FSB.
