ok.. i have been seeing people post that they have a 2.8c or 2.8e etc... i thought that C meant celeron... or am i wrong? is C northwood and E prescott?

that's all..

thanks...

It doesn't mean celeron, but I don't now the true meaning of it.
 
I believe the p4's,no number= willamate, a= 400 mhz fsb norwood, b= 533 fsb norwood, c=800mhz fsb norwood

yes.

chips are confusing these days, but basically the pentium 4 comes in a bunch of different flavors.

original P4 "Williamette"- socket 423 and, later, 478. These had 256K L2 cache and sucked:p

P4 "Northwood" - socket 478, 512K cache. Come in "a" (400FSB), "b" (533 FSB, I *think* the highest end of this was the first hyperthreading processor), and "c" (800FSB, all hyperthreading).

Now there are the P4 "Prescotts", aka P4 "e", with 1MB L2 cache.
 
ok... i get it now...

so getting a celeron would probably be stupid... cause i thought that peopel were overclocking 2.4 celerons and shit that were $75... or would an MP 2400+ for the same price blow it away?

yeah, don't get a celeron under any circumstances. They blow.

If you do a lot of video encoding and the like, get a P4 "c" or "e". This will be a bit more expensive than the AMD equivalent speed, but still very capable.

If you primarily are a gamer, get an Athlon, either something like a 2600+ or 2800+ or, if you have the money for it, an athlon64, which are VERY good gaming procs and run neck-and-neck with the P4s, beating them in a surprising number of tests.

I REALLY want to upgrade my 1.6a:(
 
For gaming, a Celeron sucks. However, I have 2 Celerons, a 2.0 and a 2.4, and for basic office stuff, and content creation they do very well. I wouldn't want to game on them, but for basic stuff, they are perfectly, fine. In fact, I have the Celeron 2.0 in an HTPC and it does all my video needs perfectly.

Williamette was Socket 423. Thought I would point that out to youy since I've seen you say 473 about 3 different times now. :)

well, I'm saying that if he's going to build a Celeron machine, he might as well spend the same amount of money on an AMD setup and get a LOT more performance. Lots of prebuilts like celerons though, and like you said they work OK for office/internet. Then again, EVERYTHING works OK for office/internet;)


merlin: socket 423, d'oh! I knew it was 4-3 and 478...didn't realize how much smaller the first williamettes were.
 
The number has nothing to do with hyper threading, just bus speeds and core. A = 400 mhZ FSB northy, B=533 mhZ FSB northy, C=800 mhZ FSB nothy E=Prescott (800mhz fsb).

There are B's, such as my 2.66B that don't have hyper threading, and some B's thad do, such as the 3.06B. The number has nothing to do with this.

The only thing that doesn't make since is the Prescott 2.4A... Which is a prescott core, and 533 mhZ fsb. WTF? :confused:
 
Intel just uses the letters when there is more than one processor at a particular speed. Contrary to belief, the letters after the processors arent related to a particular core type (except for the 800MHz FSB Prescotts which are always "E" CPUs). This is why there is a 2.4A which is a Prescott and not a 400MHz FSB Northwood.

The original "A" CPUs were the 1.6A, 1.8A, 2.0A P4s which were all Northwood 400MHz FSB CPUs, this is because 1.6, 1.8 and 2.0GHz Williamettes also existed. The 2.2GHz and up 400MHz FSB Northwoods didnt have an "A" designation however.

The same goes for the 533MHz FSB CPUs, the only processor with the "B" designation was the 2.4B, as the 2.4 was available as a 400MHz Northwood CPU as well as a 533MHz FSB CPU. The 2.26, 2.53, 2.66, 2.8 and 3.06GHz 533MHz FSB CPUs were the only CPUs of their speedgrade, so they didnt have a letter designation either.

Then came the 800MHz FSB CPUs, these are quite strange, as Intel doesnt actually list them with any designation at all, however it has just become the norm to use the "C" designation for every one of these chips.

Then of course there is the 800MHz FSB Prescotts, an easy one... all of these are "E" chips. The last chips are the 2.4A and 2.8A CPUs, these are 533MHz FSB Prescotts, and gain the "A" designation, as a 2.4A and 2.8A didnt exist beforehand.

Intel have been doing this for many years now, the same thing occured with the Celerons. There was a 300A as the Celeron 300 cacheless version existed, however the 333MHz version only came with 128KB L2, not in cacheless form. Hence it didnt have the "A" designation.
 
In the simplest terms its the revision code. With each revision there should be improvements such as faster FSB, larger cache, smaller die, etc. Intel and AMD like to add supercool code names, too, like Excelsior or Lamborghini or whatever...
 
2.4A however is the prescott NOW!

2.4B is the northwood 533fsb

2.4C is also northwood 800fsb

All E's are prescott also (800fsb)!

What you want to buy now is a C class processor..

Celerons have white box packaging (as in the retail box is white) and 128KB L2 cache slapped all over them.. its hard to miss it

Pentium 4s w/ 256 KB L2 cache are the willamete cores!

Any Pentium 4 w/ 512 KB L2 cache (and not an E slapped on it is also a northwood core)
