The Pentium III Hits 1 GHz
The Pentium III Coppermine was the first commercial x86 processor from Intel to attain a clock speed of 1 GHz; a 1.13 GHz version was even released, but was quickly taken off the market because it was unstable. This new version of the Pentium III improved the Level 2 cache—now on-die. It was faster than the 512 KB external cache on the first model and was touted as a feature able to speed up the Internet experience. It was released in three versions: server (Xeon), entry-level (Celeron), and mobile (with the first version of SpeedStep).
| Code name | Coppermine |
| Date released | 1999 |
| Architecture | 32 bits |
| Data bus | 64 bits |
| Address bus | 32 bits |
| Maximum memory | 4 GB |
| L1 cache | 16 KB + 16 KB |
| L2 cache | internal, 256 KB (CPU frequency) |
| Clock frequency | 500–1,133 MHz |
| FSB | 100-133 MHz |
| FPU | built in |
| SIMD | MMX (SSE) |
| Fabrication process | 180 nm |
| Number of transistors | 28.1 million |
| Power consumption | 25-35 W |
| Voltage | 1.6 V, 1.8 V |
| Die surface area | 106 mm² |
| Connector | Slot 1-Socket 370 FCPGA |
A slightly improved version (Tualatin), with more L2 cache (512 KB) and centering on a 130 nm process, was released in 2002. Essentially intended for servers (PIII-S) and mobile devices, it was less common in consumer-level machines.

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.
