Re: "I'm batting pretty close to 1.000 on CPU predictions. It isn't my fault that Intel is making bad decisions, but it is kind of fun for me. Batting 1.000 ?

The chances of that happening are pretty close to zero. Scumbria {========================================}

It is a very immature design, and is already running fast. The deep pipeline on Willamette is going to cause other processors a lot of trouble, including Athlon, PowerPC, HP, Sun, Alpha, and Merced.

Re: "Re: "I'm batting pretty close to 1.000 on CPU predictions. It isn't my fault that Intel is making bad decisions, but it is kind of fun for me." Did you forget these double flip-flop posts ? {==========================================} To: milo_morai (93708 ) From: Scumbria Thursday, Feb 17 2000 1:24AM ET Reply # 93728 of 93755 Finally the truth comes out- Yesterday, Intel demonstrated a Willamette processor which was not air cooled and which clocked over 1500MHz. At the time, Dr Albert Yu, senior VP in charge of desktop architecture, said that one ALU had been specially optimised to run faster than the rest of the microprocessor. But Intel was chary of saying that Willamette will run at 3GHz, and, in fact, kept describing the microprocessor as 1GHz/500. The reason for this, according to representatives, was because end users and consumers would be confused by describing the chip as 1.5GHz. 1. The 1.5 GHz CPU was not air cooled. 2. The fact that an ALU runs at 3 GHz is almost inconsequential. All that an Intel ALU does is 32 bit add, shift, and logical operations. Running that tiny piece of the pipe at 3 GHz will have almost no affect on overall performance. 3. The real clock speed was a hybrid 1GHz/500 MHz. Willamette is no threat to AMD for the forseeable future, if ever.

Any comments? I looked over the slides. The double pumped ALU looks better than expected. Someone posted to me several weeks ago that add/subtract take 1-1/2 cycles, but that does not appear to be the case. The ALU can do forwarding from clock edge to clock edge, and can also forward data from a load to the ALU on half cycle boundaries. This will improve performance considerably. Willy is going to be a very good CPU. However, one advantage that Athlon has is that it will be moved into faster processes more rapidly, reducing the GHz delta between the two processors.
