The First Mobile Dual-Core
In 2006, Intel announced the Core Duo. The first dual-core processor for portable PCs boasted excellent performance—much better than the Pentium 4. It was also one of the first x86 processors to be truly dual-core. The cache, for example, is shared (whereas the Pentium D was more like an assembly of two processors in the same package). This processor was part of the Centrino Duo platform and was a huge success. The only drawback was that it was still a 32-bit processor, unlike the Pentium 4.

| Connector | Socket 479 |
A Core Solo version with one core was also made available, and the low-power-consumption versions used a 533 MHz bus (133 MHz QDR) instead of 667 MHz. This processor was used in servers (code name Sossaman), which was a first for a processor originally intended for the mobile world. Note that this processor didn’t officially use the Core architecture of the Core 2 Duo, and it was quickly replaced by the Core 2 Duo (Merom) in portable PCs. Also, the Yonah’s Socket 479 is different from the Socket 479 of other Pentium M processors.

Wasn’t one of the key features of the Pentium Pro line of processors the increase in IRQs to 256 rather than the 16 of the previous generations?
In the days of virtual IRQs assigned by windows it's easy to forget the headache of trying to install multiple interface cards without running out of resources.
am I mistaken? or the Maximum memory figures are wrong? 4096MB or is it KB on 386, 486 and Pentium MMX class CPU's. and 64MB on P-II and so on.
Modern Intel CPU: P1-> P3 -> P4M -> C2D -> C2Q
Modern AMD CPU: P1(Intel) -> P3(Intel) -> K8 -> K10
Next gen CPU: Modified P1
The Pentium 1 & 3 are possibly the most widely base processor in modern computing. Even AMD's chips are based on them.
Hmm....
Interesting...AMD chips based on P3... EHEHEHEHHEHEHE
I think you need a...khhmmm...LIFE
cheers
Nice article that made me a little bit misty-eyed and nostalgic (being of the original 8086 generation)
Did a bit of a clear-out of my parts boxes not so long ago and found a couple of PPro's, a 486DX2/66, a 386SX and a 386DX. Threw them out but perhaps should have built a little shrine? ;p
Cheers.
There are some errors in the article, Pentium M Dothan had a 2.26GHz model which is not mentioned there, they had a VCore of 1.356V and a TDP of 27W, not 36W like stated here, also it's die size is 88mm2, not 87mm2, it also came as a socket 478 which was incompatible with the Pentium 4 socket 478 due to it's electrical differences.
