Does Intel Pentium 4 with a socket 775 performs better than socket 478?

Does it have 775 pins on it???

In that case, the number of pins doesn't really have too much to do with the performance of the processor. The important stuff is in that little wafer in the middle of the chip.

I think that socket 775 is to support the pci-express chipsets. I dont think there are any differences in performance.

YES YES YES...
The LGA 775 Socket was concibed for trespassing the 3.5 Ghz fronteer wich is imposible to pass using only 478 contacts between mother and CPU.
The LGA 775 also eliminates the electrmagnteic noises produced by the pin array by removing the pines, and has better surface of contact by using gold contacts surfaces, the surface of contact is no more a single point, it's now a a surface.
The only bad news on LGA 775 it's that the gold is very maleable and it's very sensible to contaminations and scratchs, and the socket on motherboard is also very "weak".
The "little wafer" (core) need to be "feeded" with data to process, and needs to delivery that processed data the fastest way possible, so the pins where the bottleneck for todays CPU, as AMD increases the number of pins for more than 900 intel opted to use 775 contacts with electromgnetic noise near to zero, and with more surface of contact they can carry more electrcity wich means more wats and more MHZ.
Intel announces the 1066 MHZ front side bus on Q1 - 05 using this socket. There is no way to reach that FSB using FPGA 478

775 prescott have no performance advantage over 478. I have a 478 prescott, and they are supposed to have temperature issues, and 775 have solved that, but with my Tt HSF, i idle at about 30-35 and load at a max of 45. 775 tend to use DDR2 and PCI-E though on the 915 mobo's.

Better yet go for a Socket 939 Athlon 64.

Pedro,
THe 478 prescott is exactly the same core as a 775 prescott now a days, the 755 has better perfromance and bandwith, but today they are just the same, the difference is that this is 755 floor and 478 roof.
The prescott has NO TEMEPERATURE ISSUES, as it uses more refinated silicious it can carry more electricity, and can support more temperature after it crashes because of an "avalanche" of electrons because of temperature or electricity, that is why 90nm technology opers at nominal temperature of 70ºC. Wich is a lot more than the 45ºC supported by AMD or intel Northwood.
For more info on Prescott please refeer to.

There you have absolutely all info on 478, 775 and prescott.

Socket 478 and LGA 775
Intel Pentium 4 Socket 478 vs. 775

Can I put a pentium 4 socket 478 cpu into an LGA socket 775 motherboard?
