The price cuts, Intel's first since late October, are just in time for the holiday buying season.
But the company has not further reduced prices of its high-end desktop processor for consumers - the 2GHz Pentium 4 - which was dropped from $562 (£395) to $401 in the last price slash.
This time around, the 1.2GHz version of Intel's Pentium III for desktops remains at $241, its previous price, but prices for all other processors in that family have been lowered, according to information on Intel's Web site. The 1.13GHz version of the chip - the only 0.13-micron member of the desktop Pentium III family - had its price lowered from $193 to $173, as did the 0.18-micron 1.1GHz version of the chip.
The remaining five chips in the family have all been cut to $143, in quantities of 1,000.
Intel has also cut the price of one entry-level desktop Celeron processor - the 950MHz version - to $64. Five members of the Celeron family are now the same price.
Intel also dropped the prices of both chips in its Pentium III Processor-S family, the 0.13-micron chips for servers. The 1.13GHz Pentium III-S, the first 0.13-micron processor launched by Intel, was dropped from $235 to $202, while the 1.26GHz version was dropped from $300 to $241. The shrink from 0.18 microns to 0.13 microns is designed to increase the performance of chips without greatly increasing power consumption or the amount of heat generated.
The price of Intel's 1GHz Pentium III processor for servers and workstations has also dropped, with a 133MHz front-side bus lowered from $173 to $149.
