Intel Corp., as expected, Wednesday extended its new 800MHz front side bus (FSB) and HyperThreading technology to mainstream processors.
Three new Pentium 4 MPUs at 2.8GHz, 2.6GHz and 2.4GHz were introduced to take advantage of the new higher performance features.
Intel also unveiled a new 865G integrated graphics chipset and 865PE external graphics chipset, code-named Springdale, to support the 800MHz FSB and up to dual channel DDR400 SDRAM memory for the three new processors. A third 865P chipset supports dual channel DDR266/333 memory and a 400MHz or 533MHz FSB.
Intel said the combination of HyperThreading, higher speed 800MHz FSB and dual channel DDR400 memory will bring the high performance features of its top-of-the-line desktop processors into mainstream MPUs. HyperThreading is a special technique to make a single processor operate as if it were dual processors.
The 800MHz FSB is a big jump from 533MHz, previously the highest for mainstream processors. Intel last April first introduced the new 800MHz FSB and an 875 Canterwood chipset supporting dual channel DDR400 for the high-end 3GHz Pentium 4.
The new 865G integrated graphics chipset also starts Intel's Granite Peak program that guarantees that chipset driver and software will not change for at least 12 months. An Intel spokesman said platform stability over a year is strongly desired by corporate desktop PC buyers who want to avoid frequent computing hardware and software changes compounding their IT management.
The new chipsets also extend the new serial ATA 1.5Gbits/s interfaces to the mainstream PC market. The chipsets support AGP8x graphics interface
Intel also introduced five desktop motherboard configurations using the new processors and chipsets for computer makers and system integrators.
In 1000-unit quantities the new 2.8GHz Pentium 4 processor, called 2.80C, is priced at $278, the 2.6GHz (2.60C) at $218, and the 2.4GHz (2.40C) at $178.
The Intel 865G chipset is priced at $44 with integrated RAID software and $41 without RAID. The 865PE chipset is priced at $39 with integrated RAID and $36 without RAID. The 865P is priced at $36 with integrated RAID and $33 without.
Third party vendors ALi Microelectronics Corp., ATI Technologies Inc., Silicon Integrated Systems (SiS), and VIA Technologies Inc. have been licensed by Intel to supply chipsets for the new processors, 800MHz FSB and dual channel DDR400 memory.
SiS Wednesday said the Taiwan firm is shipping its SiS648FX chipset to support the Intel processors.
