ArsTechnica article (http://arstechnica.com/reviews/004/software/intel-naming/schema-1.html) about Intel's upcoming new processor numbering system.

From the conclusion:

One thing is clear to me, and that's the fact that the processor numbers aren't doing anything to really clarify, well, much of anything. There are two fundamental problems: the desktop and the mobile line have their own numbering systems, but they overlap. The Pentium M rates a 7XX number, but so does the 1066MHz FSB, 2MB L2 cache 3.8 GHz Pentium 4!

The second, related problem, is that of double encoding. The architecture names are reflected in the numbers when they are already reflected in the product name. The only thing that makes the Mobile Pentium 4 a 5-class CPU is the fact that it's not a Celeron M (3XX) or a Pentium M (7XX). In this way, the model numbers just repeat what the product name already tells us. More worrisome, the process numbers tell us nothing about the underlying features. Consider the Pentium M 740 and 745. The former is a 1.73 GHz part on a 533MHz FSB, while the later is a 1.8 GHz CPU on a 400MHz FSB. Clearly, to make an informed decision, you're going to need the "feature list," which at the end of the day obviates the need for the processor numbers.

If you do your homework, you'll know this. But then that's the original problem: numbers which are spat out as if they mean something obvious. Unfortunately, these new round of numbers seem even less helpful than the MHz ratings themselves, and if you've been watching the CPU world from more than just the x86 angle, you know that this is meant as chagrin.

Jeez... I'm thankful for G3, G4 and G5.

Funny thing is, despite the MHz comparison being useless when comparing machines of different platforms, MHz comparison is a solid indicator of relative performance in the Apple world itself. As far as I know, every new processor that Apple incorporates into a new system has a higher MHz clock-speed than the ones it supersedes. So Apple has never had the problem of a potential customer wondering if a 1.25GHz G3 is faster than a 800MHz G4, the way one might think that a 2.6GHz Celeron is a better performer than a 2.0GHz Pentium 4. We will soon be in the ironic situation in which Apple is the only manufacturer perpetuating the MHz Myth.

In retrospect, Apple has done well to devise a product line (based on processor development out of its control) that, with each new Mac, shows an improvement in performance in line with an increase in numerical specifications: this is essential for us dumb consumers.

Bring on the Dual 3GHz G5! That will be, like, loads better than the Dual 2GHz G5 (and, boy, won't it be...)

It's not as bad for Apple, but Apple is not so entirely innocent either. Keep in mind that the G4 has undergone some changes since it's introduction and the current G4s are not the same as the first G4s. At the introduction of the digital audio PowerMacs, the pipeline of the G4 was extended greatly and, IIRC, it was reported to have worse performance than the previous G4s at the same clock speed. This is the same problem Intel had at the P4's introduction (same speed PIIIs were faster) but Apple has such a smaller customer base, it went by nearly unnoticed. I don't follow chip changes closely, but I wouldn't be surprised if there have been numerous other changes with the G3 and G4 since introduction too.

Why cannot everyone just refer to some better benchmark of speed? Perhaps "FLOPS". I am no computer genius, so correct me if I am wrong here. No doubt FLOPS would not be perfect either, but at least it would seems to address basic speed at the operations level. No?

Perhaps universal benchmarks are impossible now that computing tasks are so disparate in nature.

It’s like trying to come up with a universal benchmark for vehicle performance. Sure, an F1 racecar is fast… unless you’re driving it on a swamp-buggy course.

While in school, I remember various SGI machines running circles around everything while manipulating high-resolution medical imaging. However, these same machines were only average on more mundane office tasks. Same goes for the G4, great parallel processing via altivec but mediocre performance on other tasks.

I don't think it's quite the same. G3 and G4 refer to chip generations. They aren't arbitrarily named for the sole purpose of quantification such as Intel's 7xx, 5xx and 3xx families.

Yeah. I was kinda thank god for not having arbitrary designations and confusing specifications between families.
