Pentium 4 vs Celeron....

How much of a performance upgrade would a Celeron E1400 be from a Pentium 4 521.
Got the celeron for £6...

P4 521 HT
2800MHz
1 core
2 threads
800MHz FSB
1MB cache
Prescott


Celeron E1400
2000MHz
2 cores
2 threads
800MHz FSB
1MB cache
Allendale (i think)

both LGA775

System has 2GB DDR2 RAM
ATI Raedon x1650SE
HP DC7600 SFF.

More about pentium celeron
  1. Celeron wins hands down! Make sure you check your mobo's CPU compatibility, it may need a BIOS update or not support it at all (more likely with it being an HP)
  2. I try it and see if it works.
  3. The chipset supports the CPU, i think i need to upgrade my BIOS...
  4. The chipset supports it, but it doesn't mean the motherboard will...
  5. You need at leased an intel 945 chipset to use a dual core chip like a pentium d.

    That celeron is much much newer its more like a core2duo.

    A 945 board like the one in your HP with the newest bios should work.
  6. Here is the chipsets cpu support list= http://ark.intel.com/products/chipsets/8765
  7. Most OEM's *** on the offical support lists and lock their OEM motherboards to only support a select few. As in the case of the HP the last bios was updated in 2006 to add support for Intel Pentium 4 Processor microcode for F34, F41, F43, F44, F47, F49, F4A, F64, and F65 steppings.
  8. Ah pieces of ****, doesn't work, guess i have 2 spare CPUs (the other being a Celeron D 360), thanks for the help everyone.
  9. The real bummer is that hp uses a funky mobo.. so you cant even get a cheapo or ebay board to upgrade the computer with.
