The 3.8ghz Prescott cpu might eek out a tiny victory from time to in win9x, while the dual core will probably have a small advantage in WinXP

That top one would not be considered part of the Pentium 4 family would it? Also, would that 672 beat out the fastest extreme edition Pentium 4?

... the one in the trash. 😈 I was on the AMD train during the P4 era until Wolfdale came out.

The original P4 EE was 3.46ghz ... but otherwise not substantially different to any other P4. So the faster clocked prescott will probably beat it in most benchmarks.

But remember that, clock-for-clock, Northwood and Gallatin are slightly faster than Prescott in programs that don't take advantage of SSE3. Period accurate games certainly don't use SSE3, and would more than likely prefer Northwood/Gallatin's shorter instruction pipeline.

The 1066MHz FSB, larger cache, and shorter pipeline of the Gallatin P4 EE 3.46 should more than make up for a 333MHz deficit in clock speed.

S478 or LGA775?

If LGA775, I would go with the fastest Pentium D. For S478, the 3.4 Northwood unless you plan on selling your firstborn for the Northwood EE.

Period correct is going to be XP, and dual core is going to help a bunch over a slightly faster clocked single core.

Or you could go with a dual socket Pentium IV Xeon system.... dual 3.8Ghz Pentium IV Xeon is pretty sweet for a Pentium IV based system.

What was the latest, fastest Netburst chip?

Well not a P4 but since someone asked about fastest NetBurst - Anyone ever try using the ‘Tulsa’ socket 604 Xeon's for gaming?
The Xeon 7140M has 3.4ghz, 800mhz fob, 2mb l2 but interestingly enough has 16mb L3 cache. I’d be curious to see if l3 cache helped NetBurst, probably not enough to compensate for less fab and less L2 cache.

The 3.46 EE gets beaten by the 3.8 GHz 670 in a few popular games of the era per period online reviews: https://www.anandtech.com/show/1695/6.

Even the 3.73 EE loses to the 3.8 GHz 670 in some games. The 2MB 600 series Prescotts had a higher cache latency than the 1MB 500 series, so there are actually some cases where the 3.8 GHz 570 will beat the 670, like Wolfenstein: Enemy Territory. However, the 3.46 gets the overall win in that game. The 570 is 32-bit only, but you can get the 570J which has 64-bit support. Though 64-bit isn't that important for period correct software.

Edit: 570J should read 571. 😊

Pentium 4 EE 3,2GHz/3,4GHz = Best Perf/Watt for old stuff (PGA 478)
Pentium 4 670/672 = Best perf. (no OC)
Pentium 4 6x1 = Best perf. per watt and perf. after OC (depending on how high FSB can go).

Pentium 4 EE 3,73/3,46GHz great collectors CPUs 😀
You could argue about Pentium 4 EE 3,46GHz being fastest pure 32-bit CPU (all Prescott's have 64-bit capability build-in, it's simply isn't enabled/isn't working properly).

PS. Pentium 4 570J DOESN'T support 64-bit.
"J" stands for "Enabled NX-bit/XD-bit support".

Wow that Athlon FX-55 seems like the way to go in the mid 2000's! It was still beating CPUs that were released the next year.

Whoops, my bad. That should read 571 not 570J. Good summary of the late Pentium 4's there. 😀

Looking at those benchmarks reminds me why I bought a 939 a64 3000+ to replace my Athlon XP.. very competitive performance, even compared to dual cores.

Would that Xeon require a 4 way system? I think the s771 Xeon 5080 dual core may be one of the fastest Netburst CPUs. It looks pretty similar to the Pentium D 965 EE, but easier to find.

Bump but, here goes an another question; what's the fastest Pentium CPU WITHOUT Hyper Threading support?

Trying to find the fastest CPU (for Win98SE) but a proper/correct one, as Windows 98 doesn't use second core/HT at all. (And it's been said that, Win98 cannot suspend the cores at all, causing all cores (any other inactive ones) running at 100% load?)

Pentium 4 671/Pentium D 960. Both HT and multi-core can be disabled by many motherboards. Trying to find one without these features is pointless due to that.

And to that same point, even in the Prescott & Northwood P4's that "Don't have Hyper Threading" still have the HT silicon in the chip, but the feature is just not enabled. So you are acquiring a crippled chip. Does anyone love the crippled chips?

Max retro swagger P4 builds are still the Socket 423 Willamette build with Rambus memory, regardless of the CPU speed. Probably the most period correct too, since the Socket 478 & LGA 775 tended to focus more on Windows XP.

If you have a Socket 478, the early Gallatin Pentium 4 Extreme Edition chips certainly have collector credibility and would have had some sort of bragging rights back in the day.

If you have a Socket 775, there are better options than a P4 or PD if speed is your goal. I think the Pentium Extreme Edition 965 might be the fastest LGA 775 P4, but yes, it was dual core with HT. Then there were also those near mythical 4.0 Ghz P4 unicorns. Those would be a fine collector's item if you find an engineering sample.

There was a speculation, that P4 always had SMP in mind and Willamette is also a crippled HT CPU, because surprize-suprize - 180nm Xeon Foster MP has HT! And regular Foster Xeon is 1-to-1 Willamette with different PGA.
