When did Intel demo the >2GHz P4? Less than a year ago, I thought. And now we can buy them. Alpha had a 1Ghz chip in lab around 1997. In 1997 they had a 633Mhz 21164 overclocked to 733Mhz for 2 programs in the wmcc (october 1997). The fastest production alpha 21264 now is 833Mhz now? The P4 you can easily overclock of course by clocking back it's L2 cache (not to mention the trace cache of it), the cpu then slows down a factor 2 also if not more. A 1.2Ghz K7 MP outperforms a 2Ghz P4 right now at nearly every aspect, that says quite something... >>Intel just managed to get one P4 up to 3.5ghz. Thats nice.

The 1.2Ghz MP i have here gets very quickly above 60 degrees celcius. When i keep it running it only gets hotter and hotter. The MP athlon is square, the tbird is rectangular in size, so it's a completely different design! I don't doubt they clock it higher if we cool it more, but like a friend of mine already said years ago: when you get above 1 Ghz then cooling the cpu is going to be a big item. Vapochill can remove 70 watts from a processor, but i wouldn't feel quite happy to order a vapochill fridge in order to get a faster processor running :) this dual amd 1.2Ghz already gets very hot. Note the mainboard gets also nearly 60 and when i run it 24 hours a day then it gets 61 even (all celcius). >-Tom
