AMD Notebook ProcessorsAMD offers a smaller less confusing lineup of processors for notebooks, they cover budget and high end markets and are generally less expensive than Pentium counterparts. 64 bit notebooks are now available with Athlon 64's. PowerNow! is AMD's power management solution for all their mobile processors. PowerNow! can have up to 32 different settings where Intel SpeedStep uses two settings for maximum speed or battery power. Which setting to use is determined by variables such as how demanding a running application is or if you're running on battery or AC power. Mobile Athlon 64All athlon 64's are similar, the "Mobile Athlon 64" has been optimized for "thin and light" form factors and uses less power than the desktop Athlon 64 and Athlon 64 DTR. Athlon 64 DTRDTR stands for desktop replacement and this processor is aimed at notebooks that are designed to be desktop replacements (surprise!). Desktop replacement notebooks are characterized by their near desktop level performance and can be quite hefty due to size. Ex: 16 or 17 inch screens, over 1.5 inches thick, weighing over 6 pounds. The Athlon 64 DTR is basically a regular Athlon 64 but uses PowerNow! to reduce power use and extend battery life. Mobile Athlon XP-MPerformance of the Athlon XP-M is a great and a bargain considering the price of most notebooks based on this processor. If you had to choose between a Celeron or Athlon XP-M based notebook at around the same price, the Athlon XP-M would be a better choice. Mobile DuronHas anyone actually seen one of these processors in a notebook? Like the desktop line it has been supplanted by the Athlon XP due to very competitive prices.
