- 0.13 micron manufacturing technology
- 128 KB level 1 cache and 256 KB or larger level 2 cache.
- Data prefetch mechanism.
- Double-data rate Front-Side Bus, which allows the CPU to transfer twice as much data while running at the same 100 MHz or 133 MHz frequency as older generations of AMD K6 or Intel Pentium III/Celeron microprocessors.
- Support for MMX, 3DNow! and SSE instructions.
All Athlon XP-M CPUs are based on two different cores - Thoroughbred and Barton. The difference between them is in the size of level 2 cache - Thoroughbred processors have 256 KB L2 cache, and Barton processors have 512 KB L2 cache.
With the exception of desktop replacement microprocessors, which can be easily identified by AXMA* prefix in the part number, all Athlon XP-M processors have lower power consumption than desktop XP CPUs due to lower core voltage and PowerNow! feature. Many Athlon XP-Ms were manufactured in the same 453-pin PGA package as desktop processors, and could physically fit (but necessarily work in) desktop motherboards. Athlon XP-M CPUs for thin and light notebooks were produced in smaller 563-pin package.
Like desktop Athlon XP microprocessors, all Athlon XP-M parts are marked with rated speed. Please see AMD Athlon XP identification page for relationship between rated speed and actual speed of AMD Athlon XP-M CPUs.

At a glance
Socket 563
Are there any MP's with 333 FSB?
In the side bar under 'At a glance' two bus speeds are listed for the MP CPUs: 266 and 333. I don't see any listed with a 333 MHz FSB and if I'm not mistaken, the model number would end in a 'D' if it was. Are there any MPs with a 333 FSB, or is the info in the side bar incorrect?
"Rated is not frequency"
Please dont use the PR-rating as the operating frequency (in 'at a glance' and in the main description of the processors).
The PR-rating is nothing more then a model name reflecting performance compared to other models of the same kind. AMD never 'rated' frequencies of their processors other than the actual frequency they work on. They rate PERFORMANCE, not FREQUENCY.
