The 865PE

[Chaos]

Well I found this for you Intel junkies.


The good news for Pentium 4 buyers on a budget is that the 865PE should show substantial performance deltas over older 845-based systems in applications where memory bandwidth matters. If the 865PE can best the 850E, and only trail slightly behind the 875P, then there's no reason for most users to even consider an 845 system . Intel is now poised to deliver a level of performance into the market for mainstream home and business PCs that is unprecedented. Coupled with Intel's new 800MHz FSB CPUs, the 865PE can become the core of very affordable PCs.

This one seems cool.

The only real difference between Springdale and Canterwood is that Canterwood has PAT technology which offers a 7 - 8% increase in performance and the catch with PAT is that it will only work when the FSB and memory bus are running 1:1.

I believe there are a few morte differences. the 875 will take ECC ram has has more raid functinality than does the 865, htough for the average user this is generally inconsequential.

I thought PAT was enabled on anything past 200FSB and 800/STRAP no matter what the mem settings ; 3:2 , 5:4 , 1:1 , etc

Am I wrong in this ?

It seems that asus and abit have found a way to enable PAT on their Springdale boards with just a BIOS update, there is a good article at tomshardware.com about how they did it :D

u guys are soo funny jeesh..the PAT is a marketing gimmik. check the inquirer.com i saw it somewhere that it said pat was just a marketing gimmik:thumbs do

:rofl: just like that hyperthread thingy then right..? :rofl:

[theyneverknew]

PAT must be one hell of a marketing gimmick since it actually increases memory bandwidth : party ha

[Wiggo]

Sorry but it's physically impossible for it to increase the memory bandwidth (that's what overclockin' is about) though it can make better use of it.

[ufuk21p]

The Asus P4P800 (i865pe) is better than some i875p based mobos. Unless the prices come closer bw 875p and 865pe, the 865pe mobos are the better choice. The saved money can be used to buy PC3500 or even PC3700 rams providing a higher memory bandwidth and great overclock potential that comes with them.

[mxmai]

yeah there's actually a few 865pe boards that can outperform some of the not-so-hot 875s now.

ABIT and ASUS have both unlocked "something similar" to PAT, and claim significant performance boosts.


My P4P800D is fast enough for me.

I think I read that the 865PE chips are just 875P chips that didn't pass Intel's testing for PAT. Officially PAT is disabled in the 865PE, unofficially mobo manufacturers have nebaled it but just can't call it PAT (MSI call it MAT, Asus call it Hyperpath). 865PE also still has the CSA bus gigabit LAN if the manufacturer chooses to use it. Dunno about the ECC but realistically performance users aren't interested as it drops performance anyway

[ufuk21p]

fragman, that should be correct information but I'm not 100% sure. I read something similar too but one never knows until u get an electron microscobe and open up the chipset.
