ColdPower,
I'm not sure about your number of months, I thought it was more like six since the failed 1.13 Coppermine until the successful Tualatin.
However, either way, I don't think it changes that much.
First, I am not a fan of the K7 because I can not stand computers with them in it. It is not just a technical dislike, I can not stand the heat they generate or the noise. Needless to say, the Pentium 4 is awful beyond words.
Also, the K7 is, if you give it some thought, a really bad implementation of the P6. Considering the Coppermine generally outperformend it and was released 4 years earlier (meaning the P6 core) and was MUCH smaller and used MUCH less power, the K7 to me is failed technology that had some usefulness. Luckily, Intel failed worse with the P7. Compare, for example, the K7 with the Pentium M. It is larger, uses more power and is considerably slower. The K8 has a hard time competing with it, and this is comparing a mobile to a desktop processor. The Pentium M eats up the Turion. Also, the Pentium M is nearing end of life, and will be replaced by the Merom, so this puts the K7 and K8 (more like K7+) in an unflattering perspective. I do have to say though, the improvements they made with the Athlon 64 were all the right kinds even though they were relatively minor. The processor is improved with regards to processing power for the watt, is not much bigger, and has a pretty impressive IPC compared to the K7. Still, compared to Intel's mobile processors, it is less efficient and will be facing much stronger competition next year while it gets very little improvement by comparison. Also consider that AMD put the memory controller on the processor for performance, and still can't beat the Pentium M without it, despite being larger and using a lot more power. So, how good is it really?
Now, with regards to your question about the Pentium III and the Athlon, you make a good point that can not be completely invalidated. It would have been an imperfect solution, but I think when it is put into perspective, it is far better than what Intel actually went through. For example, the Pentium 4 has been getting outperformed for much longer than nine months (even using your number) and on top of this uses massive amounts of power and is huge compared to the Athlon 64. So, it kind of has three strikes on it. Now, compare a Pentium III to an Athlon, and you get the Athlon outperforming it by virtue of it's higher clock speed, but it uses much more power and is much larger and more expensive to make.
Also, the actual sales of the highest performing processors are quite low, and I remember when they announced these beasts, not many people felt like they needed anything nearly so powerful. Intel was paper releasing a lot back then, you probably remember them releasing the 800, then going straight to 1 GHz, and later filling in 866 and 933. I worked at Pratt & Whitney back then, and I would talk to Intel constantly, and we had a very close relationship with them (because we were a huge account) and were very high priority. We could not even touch a 1 GHz, not even get a sample, for a very long time after it was announced. Even the 800s were in very, very short supply at the time the 1Gs were announced.
At the time, I actually was talking to AMD and trying to get them into our company because I felt they had the better product for what we were doing (computational fluid dynamics, which is very floating point intensive), but Intel had come out with the Pentium III and AMD had no big company selling their machines in the business line, so Intel won. SSE made up for the slower x87, and AMD never adequately supported 3D Now! so it was not even relevant.
Also, if Intel had to, they could have gotten the Coppermine to 1.13, in fact they did get it to 1.1 with a Celeron. The reason it had so many problems was not the core, but the magnificent L2 cache. They could have relaxed the timings and gotten it to 1.13, but they didn't have to. They also could have improved the P6 in other ways (besides clock speed) like increasing the FSB bandwidth or simply adding more cache. Both would have made sense since memory bandwidth was the Achille's heel of the P III, and also since the die was so small 512K would not have made it too expensive, even on .18.
I think any of these products would have been more competitive in most markets than the ridiculous P7 which has to be considered a mainly marketing processor. There were so many compromises for clock speed that make the processor unattractive, it is hard to believe it was made for anything but boasting a high number to customers. And, yes, I agree with you that Intel would not have been in perfect shape for periods along the way, and specifically what you mention is a very good example, but I do think it would be better than the non-competitive situation Intel has put themselves in by going with that vile pig known as the Pentium 4. This processor is contemptible it sucks so bad. But, gladly, they are losing market share and will realize they can't pull their nonsense on people without consequences (remember the Rambus fiasco?).
I think an irony of the Pentium 4 will be, that as dreadful a processor as it is and was, a lot of the technology in it will be used successful in other projects. I could be wrong though.
