Their prices seems to be excessive anyway and I don't know if the 1MB cache more on this P4 did some differences. Should be interesting to compare a the 478 1MB cpu with the 775 2MB at the same clock (beside faster chipset/ram).
P4EE :
1) Gallatin (512kB/2MB L2/L3) PGA 478 = 3,2GHz, 3,4GHz
2) Gallatin (512kB/2MB L2/L3) LGA 775 = 3,4GHz, 3,46GHz (first 1066MHz FSB CPU)
3) Prescott-2M (2MB L2) LGA 775 = 3,73GHz (can be replaced with any other Pentium 4 without 1066MHz support, no "new features").
You can compare 1MB with 2MB and 2MB L3 on LGA 775 😀
For best comparison, you simply need a 775 Gallatin, Prescott-2M and regular Prescott.
One cpu frequency (3,4GHz) on all of them, is possible.
Also, all those CPUs have LOCKED multipliers (unless you have ES, which MIGHT be unlocked).
Best P4 MB (for OC), is P5WD2 Premium from ASUS, 800MHz FSB ones should work with some P45/X48 boards (if you want DDR3 😉).
For fastest Pentium D... we have three parts :
Pentium Extreme Edition 840 (first Dual Core CPU from Intel, or two Prescott "E0" on one package)
Pentium Extreme Edition 955 (first 65nm CPU from Intel, oldest CPU with Win10 x64 compatibility)
Pentium Extreme Edition 965 (last Netburst class CPU with 2 Core 4 Thread configuration, and also highest clocked Dual Core).
They are interesting in two ways :
1) 2 Core, 4 Thread CPUs (no other Pentium D CPUs have HT enabled),
2) Fully unlocked multipliers (up to x60).
For Pentium D (regulars), we have :
Pentium D 805 (533MHz FSB + latest Smithfield stepping "B0"),
Pentium D 960 (for latest stock clocked Presler, I recommend checking if it's stepping "D0" for best thermals/power usage).
PS. There is NO WAY, for Pentium D to work in PGA 478 (since they use additional pins for between die communication).
