Specs are easy to compare with competitors specs, whereas model names are difficult to compare with competitors' model names.
No, the reason Intel is having to drop the pure-GHz rating of their chips is because the Pentium M breaks it. It's a low-clock, high-efficiency architecture (akin to Athlon). All of their future lines will now be built more like the Pentium M and less like the Pentium Pro architecture. It's not one iota different from AMD's rebranding of their CPUs to get away from MHz/GHz -- because, as we've known for decades, clock speed isn't everything.
This is the same reason we had the Pentium, instead of the 586. 586 referred to the 5th generation of the x86 architecture (a technical spec), whereas Pentium is a name brand which can be patented.
The move from 80x86 naming to word-based naming was purely one of trademark issues. A number cannot be trademarked, and so Intel could not prevent its competition from using "486" in their monikers or advertising copy. Pentium, however, is a word that can be trademarked (
not patented -- there is a huge difference) and Intel could then ensure that there would never be a "AMD Pentium 150" or the like.
But with the Pentium, if the same Joe Blow walked into a store and said "I want a Pentium", the salesperson could only give him an Intel product
There's no legal requirement to do so. It would only be illegal if the salesperson sold you a non-Pentium system while at the same time telling you that it was actually a Pentium. They could easily sell you a "Pentium class" system unless you asked some pointed questions.
I truly believe that's why AMD started their naming scheme -- to differentiate themselves from Intel.
No, it was all about the MHz myth. See above.
As for the Gates story, anybody else consider that maybe the richest man in America's idea of "free" is a whole lot different than yours or mine?
No, he has a point. I think he's loony on this one, but not as much as some may. Hardware costs have been dropping consistantly for the past two decades. I mean, heck, you can buy a new PC for only a couple hundred bucks now that's perfectly adequate for anything short of playing high-end games.
He's obviously trying to protect his turf though... and I suspect he just pissed off a lot of hardware makers with that comment. The truth is that software has a lower reproduction cost than hardare does, and while you can try to defray hardware costs by bundling things like service contracts, it's still not free.
