P4 2.4B-2.4C with 865PE-875P vs AXP 2500+ with nForce2

CPU by Zroc @ 2003-05-12

With the newly released Springdale (865PE) and Canterwood (875P) motherboards and 800FSB P4?s, intel has taken a huge leap in both stock speed and overclockability. Will this crush the competition - the very affordable nForce2 + Barton combo - or are PAT, Hyperthreading, integrated S-ATA, and Gigabit lan just buzz words?

Comparison at stock speed

Stock comparison...

There's the whole gang at stock speeds. Note that both the P4 boards default to 4:5 with a 533 proc. Also note that the 865PE is at CAS Latency 2.5 at 1:1...this is because the board would default to 5:4 speeds any time CAS was set to 2. This actually doesn't matter that much anymore with the current P4's...

I'll go into that more when I look at the boards specifically, but just note the fact for now.

Right off the bat, notice that P4's are really strong in Comanche, QIII, and JKII, while the Barton excels at UT2K3 and 3DMark. This trend will continue.

Also notice that, with the P4 533 proc, the 865PE and 875P are practically identical (in fact, the MSI board beats the Abit). This is because the 875P's PAT feature was only designed to work with 800 FSB procs. With a 533 processor, the 875P is, really, an 865PE...they're the same silicon. I'll again get into this later.
Last note to take away from the stock comparisons...those are damn nice gains by the 800 FSB P4 part, and when PAT kicks in, it's a beautiful thing.

In fact, it pretty much throws the AMD Performance Rating versus P4's clockspeed out of whack...where the 2500+ pretty much handles a P4 2.4/533, the 2.4/800 turns around and smacks the 2500+, especially on the 875P.

Stock is boring...
let's dive a little deeper...
