The Low Down
The PT800 is VIA's latest Northbridge for the Pentium 4 platform and is accompanied with the new VT8237 Southbridge which carries support for Parallel ATA 66/100/133 along with Serial ATA RAID which we will talk more about later.
We mentioned that VIA are aiming this chipset more as a budget chipset as the pricing per 1000 chips is a lot cheaper when compared to Intel's latest chipsets. Current pricing on the 875 with ICH5R is $53 US and without ICH5R $50 US. While the 865 is priced slightly cheaper, the 865PE is $49 US, 865G is $45 US and 865P is $42 US. If VIA stick to their current pricing, the PT800 chipset will be priced under $30 US per 1000 chipsets for third party motherboard manufacturers, making it a lot more affordable for motherboard companies to produce. The cheaper chipset price, of course, carries over to the retail price of the motherboard which should be similar to P4X pricing.
It's also worth noting that other companies, like SIS, have to pay royalties per chipset to Intel which adds about $5 US per motherboard to the overall price of the product, VIA do not have to pay this as it was all part of the agreement after the closure of the court case.
