AMD ClawHammer news
The rumors about the new 64-bit processor with the code name 'ClawHammer' from AMD continue. Allegedly, AMD is right on schedule and has already sent the first working A0 stepping samples from the processor to its closest partners.
The Clawhammer, manufactured using 0.13 µ technology, is AMD's first 64-bit processor and is likely to be presented to the public at CeBIT in Hanover. The schedule stipulates that production will begin in the first half of 2002 and that the desktop version of the processor will be presented in the fourth quarter. The ClawHammer has been expanded by 8 SSE registers and 8 general purpose registers, at the same time all general purpose registers are extended to 64 bits. The SSE2 instruction set extension is also supported and the prefetching algorithms have been improved. The integer pipeline will be enlarged to 12, the FPU pipeline to 17 levels, and a one or two-channel memory controller with PC2700 support will be integrated into the processor. A new type of metal cap on the processor core is intended to improve heat dissipation and protection against mechanical influences.
Other rumors claim that the ClawHammer is up to 30 percent faster than an Athlon XP at the same frequency. Based on the data known so far, AMD will present the desktop ClawHammer 3400+ at the end of the year, while Intel is releasing its 3 GHz Pentium 4. This means that the battle for the performance crown will turn into a heated phase at the end of the year.
