How do I identify the speed of an athlon xp chip

[SpiriTech]

I have 2 chips of ubknown origin and speed. How can I identify the speed by the numbers on the chip?

One # is 2711 one one corner and a "B" on the other. The other one is 2711 and "N".

thanks

I'm reading this off my dead 2100+ XP, but there should be something like it on your chips too...

On the black part with white writing, the first line should say something like
AXDA2100UT3C (the letters will vary)

The number there in the middle should be the rating of the chip. 2100+ in my case.

EDIT: and welcome to AT

If it doesn't have the black plastic part, I'm not really sure if you'll be able to tell anything besides what core it is without testing it in a computer.

It sounds as if the chip's primary information block has been erased or removed. There should be three sets of numbers, plus the trademark year in a block. Not all AMD processors are/were named XP's. When AMD was still on good terms with Intel, the AMD chips had the same "386" & "486" names as the then-dominant Intel cpus.

But Intel decided it wanted out of that arrangement, and even tried to claim that the numbers they used, 8088, 8086, 80286, 80486, etc, along with the shortened versions, were trademarked names, and AMD couldn't use them. Instead of "586", they named the next one "Pentium", and did trademark that name. AMD named a couple of theirs "K-6" cpu's, and then they had the "Athlon".

The XP was the final iteration of their seventh generation cpu. It is not named with its actual operating speed in the various ones' names. Instead, each has a "performance rating" intended to show how much work the processor does, compared to a P4 of a given speed. Without the number block, all of AMD's various Athlon and XP cpu's (as well as Durons, and then Socket A Semprons) look close to the same.
