context_page_description: Athlon is the brand name applied to a series of x86-compatible microprocessors designed and manufactured by Advanced Micro Devices. The original Athlon was the first seventh-generation x86 processor and was the first desktop processor to reach speeds of one gigahertz. It made its debut as AMD’s high-end processor brand on June 23, 1999. Over the years AMD has used the Athlon name with the 64-bit Athlon 64 architecture, the Athlon II, and Accelerated Processing Unit chips targeting the Socket AM1 desktop SoC architecture, and Socket AM4 Zen microarchitecture. The modern Zen-based Athlon with a Radeon Graphics processor was introduced in 2019 as AMD’s highest-performance entry-level processor.
  Athlon comes from the Ancient Greek ἆθλον meaning " contest", or "prize of a contest", or "place of a contest; arena". With the Athlon name originally used for AMD's mid-range processors with combined CPU/GPU processors with the GPU disabled, AMD currently uses Athlon for budget APUs with integrated graphics. AMD positions the Athlon against its rival, the Intel Pentium.
context_section_description: The Palomino core debuted in the mobile market before the PC market, where it was branded as Mobile Athlon 4 with the codename "Corvette". It distinctively used a ceramic interposer much like the Thunderbird instead of the organic pin grid array package used on all later Palomino processors. In November 2001, AMD released a 1.2GHz Athlon 4 and a 950MHz Duron. The Mobile Athlon 4 processors included the PowerNow! function, which controlled a laptop's "level of processor performance by dynamically adjusting its operating frequency and voltage according to the task at hand," thus extending "battery life by reducing processor power when it isn't needed by applications." Duron chips also included PowerNow! In 2002, AMD released a version of PowerNow! called Cool'n'Quiet, implemented on the Athlon XP but only adjusting clock speed frequency instead of voltage.
  In 2002 the Athlon XP-M (Mobile Athlon XP) replaced the Mobile Athlon 4 using the newer Thoroughbred core, with Barton cores for full-size notebooks. The Athlon XP-M was also offered in a compact microPGA socket 563 version. Mobile XPs were not multiplier-locked, making them popular with desktop overclockers.
