yes intel has long pipes but with the pentium m they go the short pipe way!

Ahh I see thanks for the insight......so basically they learned a thing or two from AMD? I kid I kid don't get up in arms about it :P

Not really. This PM architecture was based in the Pentium 3. Then the pipes just got longer from there............................................. .................to 31 pipes on the prescott.

lol, no, the dothan pentium m is based on the banias pentium m wich was an improved pentium 3 tualatin.

netburst wasnt really a mistake... intel just seems to have hit the limit of the architecture now and it seems they arent able to keep netburst scaling higher and keeping the power consumption low at the same time, so they go a step backwards to the p6 architecture (pentium 3) ,turn a tad to the right and make two steps forward wich gets them further to where they want to go than netburst would have gotten them

i think the problem with netburst was that they had to lengthen the pipeline to reach higher clocks, but the longer your pipeline gets the more complicated it gets to keep the pipeline full, plus higher clocks are hard to reach without losing too much energy to leakage...

i think its basically a result of todays manufacturing processes, you cant reach the speeds with current processes that a netburst processor would need to perform fast enough to be able to compete, without reaching insane leakege levels...

since the manufacturing process is limiting them to a certain speed they are now trying to get as much performence as possible at lower clockspeeds wich means a shorter pipe

if the current processes wouldnt have such a high leakage with the netburst architecture, wich intel didnt expect, then prescott would run a lot cooler and clock a lot higher, at least 30% for each i think.


back on topic though, amazing results, and while the pentium m seems to be weak in some tasks, its easy to see that it has a hole lot of potential wich is why intel chose it as the base for their new architecture after netburst
