Pentium 4 machines
FOR all those who have waited long enough to get value for money, the wait is finally over with the launch of Intelís 845 chipset. Not only has this made the Pentium 4 microprocessor-based systems affordable but has also ensured that this microprocessors will survive all others. Codenamed Brookdale, this latest chipset uses SDRAM in place of RDRAM making the Pentium 4 machines more affordable than ever before.
Intelís 845 has no doubt broken the monopoly of Rambus (RDRAM) over Pentium 4 but to understand various other implications one has to understand how memory type affects performance. Though, theoretically replacing RDRAM that has a bandwidth of 3.2 GB per sec with a conventional SDRAM having a bandwidth of 1.06 GB per sec should have a tremendous performance difference, lab tests by various standard labs have indicated that there is only a marginal difference in performance in terms of office applications.
offers five chipsets that support Pentium 4 processors. The Indian
market till recently had only the Intelís 850 chipset to offer, till
the launch of Intelís 845 chipset recently with PC133 SDRAM support.
The other chipsets that support Pentium 4 processors include the VIA
P4X266 with PC2 DDR SDRAM support, SIS 646 and ALI Aladdin P4, none of
which is available yet.
It is this price factor
that has been one of the stumbling blocks in the way of Pentium 4ís
popularity. The new chipset, Intelís 845 has been reasonably priced
and works well on a four-layer PCB, besides supporting PC133 SDRAM,
providing a cost effective solution with little compromise on
While the VIA P4X266 is yet to be released, this chipset is designed to work on a totally different memory subsystem. The VIA chipset uses DDR SDRAM that has a bandwidth of about 2.1 GB per second. This is higher than the bandwidth of PC133 SDRAM (1.06 GB per second) but lower than that of RDRAM (3.1GB per second). Since this DDR SDRAM is priced closer to the PC133 SDRAM, this would be an excellent choice for the existing Pentium 4 users on the price to performance ratio.
Going by the current prices in the Indian market, it makes absolutely no sense to buy Pentium III based systems anymore. To begin with a Pentium III 933 MHZ and 1 GHZ chips, the currently available configurations are priced around Rs 9,700 and Rs 11,700 that is more than Pentium 4ís 1.5 GHZ processor, currently priced at around Rs 8500. All other components are normally the same for both types of machines. A Pentium 4 based on Intel 850 chipset motherboard would cost substantially higher due to the RDRAM and the higher cost of the six-layer motherboard. A Pentium III motherboard costs marginally less than a Pentium 4 motherboard with socket 478 with an Intel 845 chipset.
By going in for a Pentium 4 on an Intel 845 chipset, one is also protected against any future software and hardware upgrades. This is besides getting a Pentium 4 1.5 GHz microprocessor which is not only a product based on Net Burst architecture, but also 50 per cent faster in terms of clock speed.
assemblers use an Intel 810 chipset motherboard with video and sound
controllers on board, while making a Pentium III processor based system.
This motherboard supports only an ATA 66 hard disk controller. This
integrated system compromises on quality and performance. The other
alternative available for the Pentium III processor is the motherboard
with Intelís 815 chipset that requires an additional graphics card.
With an add on graphics card, there is a slight price difference between
a Pentium III system and a Pentium 4, an amount provides protections in
