AMD AthlonXP 2500+ Barton Processor Review

AMD AthlonXP 2500+ Barton Processor Review - PCSTATS
Abstract: AMD built the AthlonXP 2500+ based on the 0.13 micron process, and so the core has a total transistor count of 54.3 million.

Overclockers Delight?

The chip we are testing here is based on the AQXEA stepping, and was manufactured in week 34 of 2003. There's a rumor going around that week 39 or later Barton's are multiplier locked in a way that unlocking them in a tradition sense is impossible. We cannot comment on that, but our processor was unlocked, of course, seeing as it was built before week 39.

One area where AMD has made great progress in is the quality of cooling that they are now bundling with their processors. Any early Socket A Athlon user will tell you how horrible those old retail heatsinks were - in fact often they were often just barely adequate to cool the processor at stock speeds. It seems that AMD listened the the cries from their customers, and took measures to improve the quality of the heatsinks bundled with their processors.

Enthusiasts tend to really like the AthlonXP because it is just so much fun to play with! Having the ability to change the processor's multiplier allows one to come up with an almost endless combination of speeds... And depending on what applications are used, and what hardware is in the PC, it's nice to know that you can really push your processor to its absolute limit.

Installing the AthlonXP 2500+ into the Albatron KX18D-Pro II based test system, we had some high hopes in terms of overclocking. I've heard that 2.2-2.4 GHz is easily achievable with air cooling, so let's see how well we do.

As the AthlonXP 2500+ processor is multiplier unlocked, I decided to raise the multiplier first. First 11.5x, 12x, and 12.5x with out any problems. I could even access multipliers higher then 12.5x thanks to the nForce2 chipset, but unfortunately the AthlonXP 2500+ was not up the task. Anything higher than a 13x multiplier and the system BSOD while booting WindowsXP.

Next we started to raise the FSB. The system maxed out at a rather unimpressive 170 MHz FSB, which gave us a total clock speed of 2.21 GHz. Now for some benchmarks.
