<hmaly: The trouble here is that you are comparing similar mhz cpu's. The PII only had a 8 mhz higher clock speed, and of course when the software gets optimized for the PII it will win. Here in this case, the P4 has a whopping 500 mhz higher clock speed, ...> Thank you for the civil responce. I disagree with your base of comparison. What counts (or should count, anyway) is performance on a given process. The PPro binned about the same frequency as the P5, whereas the P4 bins at 50% higher frequencies. <hmaly: And while you are right that the PPro didn't outshine the 486 by much, you must also admit that the PPro didn't sell a lot of chips.> I assume you mean P5 and not 486 ;)) We are in complete agreement here. As I have stated previously, the P4 is not the best way to go for 90% of buyers. The remaining 10% being those who either hand-optimize their code or require the bandwidth offered by the P4+i850. Do I think the P4 holds as much potential as the PPro? Well, that's the question ;). I believe indications are that the P4 can achieve amazing performance right now if, and only if, the software is properly optimized. As for scalability and other enhancements in future versions, only time can tell. I wouldn't be surprised if Intel could tweak quite a few things to achieve greater IPC. Maybe the 6 cycle L1 for fp. Maybe an improved prefetch algorithm. Maybe something completely different. And why all of the hype for a mediocre chip where even Intel is saying; wait for the next version. Which is pretty much what Intel says every time around. One thing that really surprised me this time, though, is that it doesn't support SMP. The original PPro did, although I must admit that I don't know how many sold in MP systems compared to single CPU systems. -fyo
