EETimes over Itanium, SledgeHammer en Power4

EETimes heeft een artikeltje in elkaar gedrukt met info over de Intel Itanium/Merced, AMD SledgeHammer/K8 en de extreem brute IBM Power4. Hier een paar snippers:

AMD vice president of engineering Fred Weber argued at the Microprocessor Forum here that Intel was trying to turn the X86 architecture into a "second-class citizen. With Itanium, is Intel trying to do something great, or just something that is hard?" he asked.

"With Sledgehammer and the X86-64 instruction set, AMD will show that X86 has viability well into the future. We will provide the best 32-bit computing platform, while providing a future path to 64 bits that solves the primary problem: access to larger memory. Beyond additional memory, the enterprise world has few needs for 64-bit architectures," Weber said in an interview.

By putting two processor cores on the same die, hiking the core frequency beyond a gigahertz and using deeper pipelining, Weber said Sledgehammer will offer performance equal to or better than Itanium's, and protect customers' existing applications by running X86-based code without alteration.

AMD said it will add technical floating-point capabilities to Sledgehammer and the X86-64 instruction set. Weber said dual 32-bit and 64-bit support will be possible by "defining a mode in which all instructions act on 64-bit data."

[...] Nathan Brookwood, principal analyst at Insight 64 (Saratoga, Calif.), said AMD is betting that the X86 architecture can be extended at least for the next decade, "which is a lifetime in this industry.

"If Alpha, AMD and Itanium all come in at roughly equal performance, then AMD will have the advantage because it will be superior at 32-bit [IA-32] processing," Brookwood said. "Then they can say, 'you get 64 bits for free.' Intel has defined a radical path, while AMD has taken an evolutionary approach, and many people prefer the evolutionary way because it is safer."

Dus dat over die nieuwe namen van vorige week was geen grap?
