AMD A6-3400M APU was one of the first two mobile microprocessors from "A6-Series for Notebooks" family, introduced in June 2011. At the launch time, AMD also released 6 other dual- and quad-core models, all of them using newly announced Llano core. This processor is a part of Sabine platform, and it's aimed at mid-class mainstream notebooks.
AMD Llano core is a combination of improved "Stars" (K10) CPU cores, and high-performance integrated graphics controller. The A6-3400M, manufactured on 32nm process, comes with four CPU cores, and has 128 KB level 1 and 1 MB level 2 caches per each core. The microprocessor runs at 1.4 GHz, although the new Turbo core feature can boost this frequency to 2.3 GHz when some cores are non-operational. The A6-3400M employs standard set of K10 instruction set extensions up to SSE3 / SSE4A, and common technologies, like AMD64 and Virtualization.
Unlike previous generation of mobile AMD microprocessors, that had graphics processing unit (GPU) integrated in the chipset, the "Sabine" CPUs integrate graphics on a chip. The Radeon HD 6520G GPU on the AMD A6-3400M model has 400 MHz clock frequency, and it packs 320 shader units. These units can be utilized for 3D graphics acceleration, in which case the GPU can can perform on the same level as discreet graphics cards. When used for non-graphics computations, the combined performance of 320 shaders on this chip greatly surpasses performance of 4 CPU cores.
In addition to CPU cores and the graphics unit, the AMD A6-3400M incorporates Universal Video Decoder (UVD) 3.0 and memory controller. The UVD is used to accelerate decoding of video data, including HD video. On-chip memory controller has two channels, and it supports standard and low-voltage DDR3 memory with data rates up to 1333 MHz.
The A6-Series A6-3400M accommodates a handful of low-level
improvements, such as power gating, which purpose is to reduce processor's
power consumption. For instance, power gating is used to turn off
power for idle CPU cores, graphics processing unit and/or Universal
Video Decoder. The chip also supports a few low-power states. The
A6-3400M features 35 Watt Thermal Design Power, and that number
includes the power dissipated by all chip components. The CPU is
produced in a socket FS1-compatible PGA package.
