Kак it is known, release of processors of the bar of Pentium III will be step-by-step stopped. Their place will be occupied with processors of Pentium 4. The upper models are intended for sector High End, lower — for Mainstream.

The architecture of Pentium III becomes a basis of processors Celeron. Moreover, Coppermine architecture with the cache memory of 256 KB has received new incarnation, having passed on processing technique 0,13 microns.
Also it is linked to growth of clock rates and, accordingly, productivity of processors and the systems created on their basis. After all the traditional architecture of processors P6 grounded
On a procedure 0,18 microns, has practically reached a limit. For Pentium III with kernel Coppermine this limit is in area of 1,2-1,4 GHz of what it is easy to be convinced on the basis of the analysis and approximating of results of speeding up of operation of processors with a different operating frequency (

With increase in clock rate of a kernel increases energopotreblenie the processor that creates problems of maintenance of temperature modes of a chip.

At transition on tehprotsess, operating by the smaller sizes of units, for example, about 0,18 microns on 0,13 microns, it is essentially reduced energopotreblenie and accordingly clock rate of processors raises.

In the course of production interconnectings on a basis 6 layers of two-layer copper explorers also have been used at the big ratio of a thickness of explorers to width (1,6:1). It provides reduction of an electrical resistance at high density of allocation.
