PC Processor Invention Evolution
In 2006, Intel introduced the Core 2, a new CPU family based on the architecture of prior mobile Pentium M/Core duo processors. The Core 2 was originally introduced in a dual-core configuration, then later in the year in a quad-core configuration (combining two dual-core chips in a single package). The AMD Phenom was the first quadcore PC CPU having all four cores on a single chip, and it was launched in 2007. Intel introduced the Core i-series (Nehalem) processors in 2008, which are single-die quad-core CPUs with HT Technology (appearing as eight cores to the OS) and integrated memory, as well as optional video controllers. Intel also introduced its Atom CPUs, which support x86 instructions but need a fraction of the power of traditional processors. Atom was originally introduced in netbooks, but it has now expanded to include tablets and smartphones. AMD also announced the Phenom II family of multicore (up to six-core) processors based on their K10 architecture at the same time, which supported both DDR2 and DDR3 memory.
Intel released the Sandy Bridge second generation of Core i-series processors in 2011, which included four-core and six-core processors with HT Technology that could handle up to 12 execution threads. Some versions come with an on-die video controller that allows for dynamic resource switching between GPU and CPU (TurboBoost 2.0) based on the kind of processing. Intel also revealed the 3D Tri-Gate transistor, a 3D manufacture technique for CPUs at 22nm. AMD released Fusion/HSA (Heterogeneous Systems Architecture) CPUs in 2011. (accelerated processing units [APUs]). These features include Radeon graphics, low power consumption, video, picture, and web acceleration. AMD also developed Socket AM3+ FX-81xx (eight-core), FX-61xx (six-core), and FX-41xx (four-core) processors based on their modular Bulldozer architecture for desktops with discrete graphics cards.
