    CPU Letter

    I am trying to find out what the letter after a cpu speed means, can anyone enlighten me with what it means between a 2.4b ghz and a 2.4c ghz? different versioning or what not?

    Different front-side-buses...the b is 533mhz and the c is the 800mhz Northwood cores, if I'm not mistaken (which is a good possibility ;D).

    Cheers

    The original Pentium4 was the Williamette core, with 256k of L2. The A version is the first Northwood with 512k of L2. The E version is the latest Prescott core with 1MB of L2 cache.

    So the letter deals with cache?

    No, the letters deal with architectural changes (changes to the core of the processor), front-side bus changes, and cache changes. Basically, if the processor changes but the socket that it uses doesn't change, they will generally give it a new revision letter instead of changing the name of the processor (the latest Prescott-based P4 has so many changes that many people feel that it should have been renamed. Apparently, Intel is going to tweak the Prescott core, add a few pieces of voodoo, change the socket pin count, and rename it the Pentium 5 or Pentium V).

    Cheers
