Beamer - Re: "An IA-64 processor using EV8 technology - sounds great. A 32 processor IA-64 system could issue 6 instructions per clock with SMT and dual core for a total of 384 instructions per clock - twice that of your fictitious Sledgehammer. It sounds right up your alley!"

Put 64 of these into a MADroid fictional cluster and you have 24,576 instructions per clock !!!

Let the Droids feast on that baloney.

Be a pretty big chip, though. 400mm2 at .13? What do think production costs would be, $500 per chip? Now add in the costs of the support chips Itanic requires. Another $750? Would it perform as well as a $100 Sledgehammer? Certainly not on 99% of the code base. And Sledgehammer embeds glueless logic for multiprocessing so it doesn't need expensive support chips...

It sounds exactly like what happened when $10,000 2-way Intel workstations went up against $50,000 2-way SUNs and Alphas a few years ago and walked away with most of the workstation market.

Intel has set itself up to be on the losing end of the identical set of circumstances.
