Processor Temps, Celerons & PIII's (Reply to this comment)
by vicwang
"None of both processors have a tendancy to overheat, temperature just rises a few degrees... which is one point where Intel shows that it still holds the lead over AMDs Athlon/Duron in the manufacture of microprocessors."
You're right that AMD's current processors get hotter than their Intel counterparts, but the more important thing to note is that AMD CPU's are much more heat-resistant as well. In other words, Durons/Athlons can operate stably at temperatures that can literally destroy PIII's/Celerons, due to the differences in their ability to withstand heat.
Pretty much all the tests I've seen have shown their "over-clockability" to be roughly equal in terms of percentage-over-rated-speed. In other words, Durons/Celerons can usually be overclocked to about 150%, Athlons and PIII's to about 130%, etc.
Of course, the fact that you can buy AMD CPU's at significantly higher rated speeds than their Intel counterparts (1.33 ghz Athlon vs. 1 ghz PIII, 900 mhz Duron vs. 800 mhz Celeron), and at significantly lower prices no less, strongly suggests that AMD currently holds the manufacturing edge.
"The second point being that the Celeron2s - which are exactly the same built as the Pentium3s"
Celeron 2's are not the same as PIII's, since they have only 1/2 the cache (128k vs 256k) and also 1/2 of the cache associativity (4-way instead of 8-way, if memory serves correctly). In other words, even if it somehow you could produce a "double-cached Celeron", it still wouldn't be the same as a PIII due to the differences in cache architecture.
