When Prescott finally gets room to play...

[ManDooM]

I've seen the benchies like everyone else and I know that the P4E's performance is below that of the Northwood, mhz for mhz. And I know that it won't be able to really shine until it gets it's running shoes on in the upper 3Ghz range.

So does this apply to overclocking as well? Say I oced a 3.2 E and a 3.2 C to 3.7. Do you think the Prescott would break ahead and perform faster than the Northwood at that speed, mhz for mhz? Or would they have to be factory clocked to utilize the headroom for the Prescott.

From what I have heard once at around 3.5~3.6 the Prescott over takes a Northwood. The newer steppings are supposed to overclock alot better. I know the 2.8e is a really good one.

Everything you are looking for here.

No. These things are linear just look at the graphs, all straight lines. In other words what a presshot wins at 3.2 it will win at 4.0, what it looses at 3.2 it will loose at 4.0.

Unfortunatly the presshot loses more than wins to Northwood. AND I've seen no evidence a presshot can clock higher w/o extreme cooling.

Northwood.

3.6ghz prescotts are scheduled for this weekend,but there is suppose to be huge shortages. i'm not sure if thats just an excuse.

"At the beginning of the tests for this project, we had a hunch that the resulting curves of the P4 Prescott and those of the Northwood processor would cross in several benchmarks. This was based on the assumption that Prescott, thanks to the double cache size and the 31-part pipelines, could produce more performance at a higher speed than the Northwood processor.

From this perspective, the results are sobering, because even at 4 GHz little changes in the balance of power between the two cores. Northwood is and remains the faster processor in common applications, even if the difference can be virtually ignored in application.

However, our scaling analysis has a slight disadvantage: Raising the FSB speed to up to 260 MHz increases the operating speed of the whole system and even that of the RAM. The Prescott's touted advantage, its 1-MB L2 cache, is thus less noticeable than it would be at a constant 200-MHz FSB speed.


The lesson to be drawn from this is that whenever the core speed - and only the core speed - is increased, the Prescott will always be slightly ahead of the Northwood core. Therefore it will scale better, but it cannot deliver the added performance that Intel touts. "


Hell even toms slams it


"Prescott will always be slightly ahead of the Northwood core........."

Prescott isn't even suited for that current socket, it has plans to be released for LGA 775. once the new clock rates get released on these new motherboards we'll see its true colors.

ok then ;-)

speaking of which,its already the weekend,so here

Latest info says that intel is disabling all forms of overclocking on the new socket 775 chips. Not sure if anyone will be able to get a work around, but imho they're just shooting themselves in the foot. They only stand to lose with this - the only people that overclocked anyway are the enthusiasts. If we can't overclock a new prescott, we're all gonna be buying athlon 64s. This is unless intel somehow manage to get the prescott well above 4ghz in the next couple of months in order to start beating the a64, and without amd making any kind reply... In other words, who was the stupid intel director who came up with that idea?
