P4C... does the C stand for anything?

... other than it being the 3rd P4 core.

Intel uses the 'c' at the end of the speed to designate that it's on an 800fsb. But they only use it on cpu's where the speed overlaps.

a = Northwood (not Willamette)
b = Northwood 533fsb (not 400fsb)
c = Northwood 800fsb (not 400 or 533fsb) w/HT

P4-2.0 = Willamette
P4-2.0a = Northwood

P4-2.4 = Northwood 400fsb (no 'a' because there was no 2.4ghz Willamette)
P4-2.4b = Northwood 533fsb
P4-2.4c = Northwood 800fsb w/HT

P4-2.8 = Northwood 533fsb (no 'b' because there was no 400fsb flavor)
P4-2.8c = Northwood 800fsb w/HT

Although people use the 'c' as in your example (P4C), it basically means 800fsb w/HT, although it's not an official designation.

A confusing matter (for many) very succinctly described Wingznut!

Thanks! I've described it enough times, that now I've honed it down to something presentable.

800 mhz. bus speed

The C is for the extra Cash you'll pay for the chip.....:Q

Wingnutz... to your knowledge, did "C" ever stand for a word? A code name or anything for the processor? A friend of mine thinks it does, I don't remember what... he looked at me like I was nuts when I didn't know what he meant when he said a "Pentium 4..." and whatever name he had for it. I know he didn't say Celeron or Centrino... but he pulled some other name out of it butt it sounds like... was just wondering if he actually got it from somewhere, or if he was trying to fake his knowledge of Intel processors =)

nah.. no way, its just incremental in the evolution of cpus, started all the way back w/ the good ol' celeron 300a

celeron 300 = 0kb L2 cache
celeron 300a = 128kb L2 cache (1/2 of pII (256kb))
celeron 533 = .25micron processing
celeron 533a = .18micron processing
celeron 1.0ghz = 128kb cache cB0/cC0/cD0 stepping
celeron 1.0A = 256kb cache tA1 setpping

haha this can go on forever...

Nope. It just happens to come after 'b'. If another P4 were released at a like speed, then it would be a 'd'.

 

[Jeff7181]

That's what I thought.

 

[Mingon]

to be picky doesnt it relate to the bus speed as in 100mhz, 133 and 200mhz? that would fit in better with the pentium 3 cpu's i.e 600b - 133fsb versus the 600 - 100mhz and the 600EB coppermine 133mhz. all based around the bsel0 and bsel 1 configurations on the cpu pins?

Not necessarily. See my P4-2.0 example above.

It's just Intel's way of differentiating between two different processes that have the same clockspeed.

Except in this case, it's an EE .

Maybe someone was thinking Canterwood as it is the chipset that fully supports the C.
