The Pentium III 1.13GHz is manufactured using Intel's .18 micron six metal layer process. It uses a fluorine-doped SiO2 (SiOF) dielectric for 15% reduced capacitance. This allows Intel to pack 28-million transistors into a 106mm square die. In comparison, AMD's Athlon Thunderbird packs 37-million transistors into a 120mm square die. Spacing changes were made to extend the life of aluminum as an interconnect material and push off the transition to copper. According to Intel, copper interconnects are not yet a mature technology, may reduce yields and have not been proven to be worth the trouble over aluminium at current processor speeds with the Pentium III. Notched poly profiles are used to cut .13 micron gates to .10 micron size, thereby increasing switching speed, and Intel's SSE and MMX instruction sets are fully supported.

Those are the details for what is essentially the original Coppermine CPU running at 1.13GHz. With the Pentium III Coppermine, Intel set out to make a CPU line that could scale well to higher clock speeds, and apparently they succeeded.

On a side note, as with the 33W-consuming Pentium III 1GHz, OEM systems with the 35.5W consuming Pentium III 1.13GHz will come with extensive cooling systems. The CPU we tested had only a couple of CPU fans and a large heatsink -- for a 1.13GHz CPU that's practically nude. But OEM systems will likely include a large case fan with ducting that blows directly on a fanless CPU heatsink, possibly with extra fans drawing the CPU-heated air away. As any overclocker can tell you, high-speeds demand drastic cooling.

In case you're wondering, the follow contains excerpts from the official spec we received from Intel. Their exact words are in bold:

Vcc nom = 1.8V (voltage)

Although some samples are shipping at 1.75, Intel is documenting that 1.8 is the maximum voltage at which the 1.13GHz will ship.

DICC = 23A (Current in amps)

TDP = 35.5W (Maximum power dissipation)

Tj = 62C (thermal junction, the processor is to be kept at this temperature or below)

DeepSleep = 3A (current in amps in deep sleep mode)

If you "do the math" on this (multiply voltage times current to get wattage) you will get a number that exceeds the Intel spec, however this would be incorrect as this would require that every transistor be operating simultaneously, a physical impossibility as there are lots of mutually exclusive transistors on the CPU. Intel's engineers have calculated the power requirements actually needed and come up with the number of 35.5 Watts.

But we know what you really want is the benchmarks...
