Difference between Intel, Celeron, Athlon and AMD

Wonder if anyone can help me. I want to but a new laptop and all have different types of processor, the above are most of them

Can someone tell me what the difference is? If you had to order them from best to worst what would it be?

Im finding it hard to find out.

There's no way to give you an exacting answer to this question without just giving you too much detail or simply confusing you.

The simple answer is manufacturer and chipsets.

Intel processors are the Pentium and the celeron.

The celeron is a lesser chip, usually running at slower speeds and having a smaller cache.

Several manufacturers make chipsets for the intel processors:  SiS, Via, Intel, ALi, etc.

The athlon is the competitor to the Intel processors.  They are done by AMD.  They don't fit into the sockes designed for the intel processors.

They require different chipsets designed by the same companies as Intel's (shy Intel's own version):  Nvidia, SiS, Via, etc.

The chipsets specify features of the board. For instance, the nforc2 chipset done by Nvidia incorporates outstanding audio processing capabilities.  It also incorporates Dual DDR logic.  Each version of the chipset can be different and add more/less features.  For instance, the Via KT333 supports DDR 333 (PC 2700).  The Nvidia Nforce2 chipset supports Dual DDR and it supports DDR 400 (PC3200), and I believe PC 3500.

What does this mean for you?  It means your options are wide open.  It means the market is extremely wealthy of features.  It means that it would be very difficult to go wrong with either the Intel P4 or the AMD Athlon XP.

One of the main things you should keep in mind when deciding isn't just the processor but the chipset features.  Do you need/want serial ATA (not likely in a notebook)?  Do you want Dual DDR (not likely in a notebook--at this time)?  Do you want less expensive high speed ram?  Do you want usb 2.0?

The Celeron is intended to be the cheaper less powerful version of the P4 without the thrill features such as a high capacity cache and without hyper-threading.  Then again, there are p4s without hyper-threading.

The intel processors run a bit cooler then the Athlons.  The newer Athlon XPs based on the thoroughbred B  (and Barton) core does run much cooler then prior  cores.  There aren't many Athlon XP notebooks to the best of my knowledge.

Thank you very much. Although I still dont fully understand, and I appreciate that the topic is probably very involved but never-the-less, you have reassured me that either an Intel or AMD will be good for me.

Many thanks.
