Hello everyone, recently I saw that someone sold some "useless" PC parts, like (not so much, good for paint job) rusty ATX case and Asus P5P800 SE motherboard with stock IDE cables, unknown CPU and 3.5 HDD drive bay for 5.25 slot.

The thing is that that's all costs cheaper than a PCI Gigabit network card, and this motherboard has gigabit networking supported in Windows 98, so it will be more efficient to buy the lot with motherboard, although I seldom use ethernet connection on such an old system, it will be a nice bonus for me.

So, as I've said before, it has an unknown processor, and I have Pentium 4 531 from some MSI OEM board on 915 chipset in my collection: it's 3.0 GHz, 800 MHz FSB, 84W CPU based on the Prescott architecture. Will there be any significant difference in performance between this and Pentium 4 2.8 GHz, 800 FSB based on Northwood architecture? Who's faster?

I plan to use that P5P800 SE with P4 Prescott in Windows 98, like I use my Gigabyte GA-8IPE1000 with P4 Northwood. One thing to note, these boards are basically on the same chipset (865PE).

Since Win98 software is mostly not optimised for Pentium 4 processors the longer pipeline of the Prescott may actually decrease performance. Prescott is also supposed to draw more power and run hotter at the same clocks.
In any case I would not expect a noticeable performance increase.

No, it's not really significant.

3dmark2001: P4 3.0E (Prescott) is 2.7% faster than P4 2.8C (Northwood)
3dmark2003: P4 3.0E is 2.7% faster than P4 2.8C
Quake3arena: P4 3.0E is 2.2% faster than P4 2.8C
Unreal T.2003: P4 3.0E is 1.6% faster than P4 2.8C

Eh no way. Prescott is horrible and hot, Northwood is the best P4.

Depends on stepping.

I must be some kind of standard: the anonymous gangbanger of the 21st century.

Thank you all for the info. I've decided to stay with my current Northwood CPU (it has hyper-threading btw, but I disable it if I use Win98), and I've also bought a gigabit PCI network card — my previous 100 MBps one was faulty and hung the PC while it was initializing.
