Quick question on intel cpu

[ezland00]

On Intel cpu's they have a,b, and c next to them(example: 2.4a, 2.4b, 2.4c) What does each letter mean?

 

[Mik3y]

dont forget e. each letter stands for the type of core used for that cpu. the "c" stands for northwood core, and the "e" stands for the current prescott core. the "a" and "b" are older cores. i forget what their names are.

I am not 100% on this, but 2.4A and 2.4B are the same core, (Northwood) but 1 is 400MHz FSB (A) and the 2.4B is 533 FSB. the C is an 800 FSB Northy, and the E is a Prescott (which all run at 800)

Ex.

2.4 -- Williamette - 256KB L2 cache, 400MHz FSB
2.4A - Northwood - 512KB L2 cache, 400MHz FSB
2.4B - Northwood - 512KB L2 cache, 533MHz FSB
2.4C - Northwood - 512KB L2 cache, 800MHz FSB, Hyperthreading
2.4E - Prescott --- 1024KB L2 cache, 800MHz FSB, Hyperthreading, SSE3, Longer Pipeline

So far, that's what it is, however, there is a new letter about to emerge. Letter 'F', which will note 64-bit compatability.

 

[ezland00]

thannks guys.

One more question; does anyone know the fastest way to contact Intel Warranty service? I tried to call them up, but they ask for me credit card and charge $20. Is this how their service works?

 

[o1die]

Look again on their website. I've contacted them twice, and they didn't ask for $20 upfront. They replaced my 2.4b in about a week.

 

[ezland00]

Can you give me the phone number you used? I can't find it.

thank you
EZ

Actually, a 2.4a is a Prescott 533MHz FSB w/out Hyperthreading. There was no Willamette 2.4GHz, so the flavor without the letter designation is a Northwood 400MHz FSB.

Similar to the 2.26GHz and 2.53GHz varieties... Since there was no previous version of the same MHz speed, those too have no letter designation.

and people think amds naming scheme sucks

I was just giving him a popular chip speed and applying it to all the letters to make it easier to understand, that's why I noted it was an example.

hey has anyone noticed the naming schemes for some of the new intels these days? i went into frys and just realized that there are numbers like 415 or 425 or something like that (maybe it was 735, i don't really remember) what's going on with that?

ahh, awesome links, thanks!

also, i've been seeing alot more 2.xA's (i.e. 2.4A) being sold lately... i thought they were older technology? i think i read somewhere in the Hot Deals forum that they're actually prescott cores? can anyone shed some light on this?

edit

wingznut already answered this earlier in this thread.. thanks man! you're a cpu guru!

this is all from my shady memory so please correct anything thats wrong.

 

[caz67]

Are you confused yet..LOL

 

[Gamingphreek]

THe old Revision A's denote asynchronous caching also. THat greatly improves performance. Other than that the rest are right.

Just one repair on the list from Spikesoldier. There is no 2.6A. Just 2.4 and 2.8 Prescott's.

Intel P4 533fsb

Otherwise, nice resume...

some results that i tried to decode off intel's site, + the info from you guys
