A silly question but what ever happened to the P4?D??

[nimo]

There is a P4A, P4B, P4C, P4EE and now a P4E
What ever happened to D?

 

[THUGSROOK]

i think P4C became what was to be P4D.
P4C was supossed to be 667fsb but became 800fsb insted .....i think.

then again there just may have never been a P4D designation in the works at all

I've thought about that too, I don't know though.

Maybe the original delayed versions of the prescotts were d. When they realized something was wrong and had to extend their timeframes they changed the name maybe.

calling winznut ?????? Hello ???

So no one actually knows ?

100mhz bus = A
133mhz bus = B
166mhz bus x 4 = 666 = devils number = bad marketing
200mhz bus should have been D but they decided to go in order and just use C (to cover up the lack of a 166 mhz part maybe?)

Then Prescots were slated to use E, F, etc because the northwoods/wilamates already had A - D accounted for (except they forgot about the 666 thing when designating letters).

 

[cow123]

actually it would have been 667 rounded up

166.6666666666666666666666666666666666666666666666666666 (etc)*4

I think Thugs is on to something there....Look at all the i865/i875 mobos and look at how NBS has options for 533 (the b chips) 667 (not 666) and 800 ( the c chips).....I truly think they had originally intended to jump the fsb up to 667 before they went to 800, but for reasons unknown to me they skipped it and the marketing ppl made a decision...

dont forget ~
granitebay was supposed to be a 667fsb motherboard, but it wasnt good enough to run 667fsb (by intels specs). so they dumped granitebay down to a 533fsb workstation board, skipped 667fsb, and announced 800fsb very soon after granitebay was released.

im not sure if this is how it actually happened, but it does make sense.

Probably figured AMD was planning on pushing the AXPs to 400MHz FSB and decided to push the 800MHz FSB boards out the door before the A64 hit the market. Even the most hardcore Intel fanboy should be grateful for AMD for keeping Intel on its toes. Intel has been putting out some top notch processors and motherboards lately and I think that the competition between the two has fueled a lot of that rapid change. I wonder how soon we can expect to see a Gigahertz FSB?

Gotta love what competition does for the marketplace. (Same goes for the ATi/nVidia wars). I can only hope IBM can help get desktop Linux moving forward so we can start seeing some compeition start pushing Windows development forwards at a fast pace.

166x4 using integer math = 666 and we all know how much all computer people like integer math.

Then why did Intel only make 667mhz PIII's and Celerons, newbie?

 

[Showtime]

Amen to that brother.

Haha, I would've thought someone knew this besides the closet AMD fanboy. When Intel needs to differentiate models which share a common overall clockspeed, they add letters to the GHz rating as needed.

[*]"A" designates a Northwood core, if there is also a Williamette core at the same clockspeed.
[*]"B" designates a 533MHz-bus Northwood, in situations where there is also a 400MHz-bus Northwood.
[*]"C" designates an 800MHz-bus Northwood, in situations where there is/are also 400MHz-bus and/or 533MHz-bus Northwoods.

Note that this explains why processors such as the 2.26GHz, 2.53GHz, 2.66GHz and 3.06GHz Pentium4's don't have a letter stuck onto them... they sit at unique clockspeeds, so there is no need for a letter to differentiate them from their bretheren.

So... what is with the Prescott's "E", you ask... think back to the Katmai and Coppermine. What did the "E" stand for in Pentium3 600e? "E" for "Enhanced," because Coppermine had the Enhanced L2 cache (moved onto the processor die at last, among other advances). So the "E" in the P4E is denoting that they have enhanced it with SSE3 and... stuff. It isn't there just to designate that it's yet another 3.2GHz P4, it's a new processor family.

Technically, it seems to me that if Intel were going to be consistent, then the letter "D" would have been assigned to the Pentium4 Extreme Edition 3.2GHz if anything, because it has an identical clockspeed to the 3.2GHz Northwood but uses a different core, like when the Northwood and Williamette coexisted. But the marketing department's "EE" works fine to differentiate it, so I s'pose they called it good.
