189882 2003-11-07 00:56:00 Can someone please explain in simple practical terms the difference between the Intel 865PE and the Intel 875P chipsets.
A search of the Intel site produced wonderful data sheets but left me none the wiser

Many thanks

189883 2003-11-07 01:08:00 875 has a higher speed (800/533 MHz) system bus

865 has 533/400 bus

The 875 will support faster CPU and RAM than the 865.

Thats all detailed in the first item in the "features" on the Intel site.
Otherwise they are much the same.

I suspected you would be first to respond, however the data sheet I downloaded for 865PE repeat PE states 800/533/400 bus!

189885 2003-11-07 01:31:00 875 P has dropped the lower 400 speed though .

The 865 PE says "Supports platform longevity with the highest Intel processor frequencies"

While the 875 P says "Supports platform longevity for the fastest Intel Pentium 4 processor frequencies .

Perhaps the 875 P is capable of future speeds we do not know about?

Perhaps its only a marketing ploy?
Probably the same bit of silicon . . . . a new name, a new market .

Your mileage may vary . . . . .

189886 2003-11-07 01:34:00 I have also read that the 865PE has 800MHz bus and I have seen a few PC's with mobos with this chipset running 800MHz bus CPUs CYaBro (73)
189887 2003-11-07 03:55:00 Me and a few friends have a mix of 875P and 865PE chipsets . Everything about them is the same except that the 875P chipset supports an Intel development called "PAT" (performance acceleration technology which is a sort of turbo boost function) while the 865PE supposedly does not support PAT .

However this is where it gets tricky . Some motherboard manufacturers found that the PAT was still built into the 865PE and have enabled it in their BIOS' which has pissed off Intel no end .

Turns out the 865PE and the 875P were virtually indistinguishable with some suggesting that 865PE chipsets are just 875P chipsets that fail inhouse Intel stability testing before shipping .

Comparing my 875P machine with my mates 865PE machines shows they are virtually identical in performance tests and in games .

Read the exact same thing in a magazine article last week.
