Hi JC! Welcome to SI... today's AMD action must indicate you bought a little more yesterday? <vbg> DISCLAIMER: I just bought more... -PT

jcholewa, When did you get on here. Damn, now I have to educate you in public <VBG> The fact that Athlon is fairly competitive with Alpha now, even using x87, speaks to how strong the FPU is. And you can't talk about compiled SPEC. I happen to know hand tuned numbers for Spec on both CPUs, and they are very close. Fact of the matter is Alpha has vastly superior compilers. We'll forget for a minute hand tuned binaries don't count for spec submissions. Athlon has stronger branch prediction than Alpha which helps with some of the misses, additionally the longer pipeline is one reason why Athlon is at 1.0-1.1 ghz and Alpha has been talked about at 850mhz. The deeper pipeline can be beneficial for hiding 'long' instructions as well. All in all I bet sledge in flat FPU mode gives Alpha a REAL run for the money. Merced & IA64 are still an unknown. They have the potential to compete, but volume and clock speed are still suspect. Remember HP doesn't have a history of designing high-clock parts. (PA Risc is only now hitting 500mhz, which is as pathetic as the crappy PPC). Regards, Steve

Steven, why do you expect that the Sledgehammer will have superior clock for clock floating-point performance than the 21364? I mean, I'm open towards changing my mindset, but I had the opinion that x86-64 still carries some baggage from the old days that can lag it a bit. Everyone seems to know you...are you the JC from Tom's or Ace's Hardware fame? In any case....welcome to the thread! ted

JC?! Welcome to the thread. I knew you'd get here some day, one way or another. ;) I was about to email you a question, but I'll ask here. Remember how that guy from rbcomputing.com went to some AMD fair where they discussed AMD's products and some future stuff? He had to take his webpage with all that info down because AMD didn't want it up. I read it before he took it down, and I seem to remember he said something about Mustang having an enhanced-enhanced 3DNow!. Do you remember something like that?
