Llano Chipsets and Socket

Llano processor is not the only component of the Lynx platform. It also uses chipsets. Since the APU already contains the memory and PCI Express bus controllers, the chipsets consist of only one chip – the South Bridge also known as FCH (Fusion Controller Hub).

AMD currently offers two FCH variants: A55 and A75. The A75 model has native support for all contemporary interfaces, including USB 3.0 and SATA 6 Gbps. The lower-end model A55 supports only old SATA 3 Gbps and USB 2.0 interfaces.


Mainboards for desktop Llano processors based on the above described chipsets come with a special Socket FM1 which is incompatible with AM3. Socket FM1 has significantly different number of pins – 905. All these pins are necessary to ensure that the CPU is connected not only with the chipset and the memory sub-system, but also with the PCI Express x16 graphics bus and monitors.


For the cooling systems, AMD tried to maintain compatibility with the existing infrastructure, so the old Socket AM3 coolers will work just fine with the new processors.

Desktop Llano Lineup

The first batch of desktop Llano processors includes four APU models with four x86 cores inside. Just like the mobile Llano APUs, they don’t have a marketing name and are assigned A8 and A6 series numbers. A8 series includes higher-end APU models with a "Sumo" graphics core featuring 400 stream processors, while the A6 series includes slower modifications with lower clock frequencies and “lighter” graphics core with only 320 stream processors.

Here is the complete list of currently available Llano processors for the desktop Lynx platform:


There are significant differences in the specs not only between the two different APU series. Two models within each series are, in fact, two totally different products with dramatically diverse heat dissipation levels. The highest-performing models have 100 W TDP, but at the same time there are models with 65 W TDP and Turbo Core support. The clock frequency of the energy-efficient processors has been reduced by about 20-25% below that of their 100 W counterparts, but the features and frequency of their graphics cores remain the same.

Llano’s clock speeds are lower than the frequencies reached by the latest Athlon II and Phenom II processors. And it means that Llano are slower processors, which major advantage will be not the performance of x86 cores, but the performance of their graphics core. So, it makes sense to upgrade from a Socket AM3 to a Socket FM1 platform only for the sake of achieving better energy-efficiency and not in an attempt to boost the performance.

In the desktop segment, AMD’s pricing strategy is to make the A8 Llano processors an alternative to junior Core i3 Sandy Bridge models. The A8-3850's main competition will be the US$134 Core i3-2105. This is a fairly new part which has the same CPU clock as the i3-2100 but a fully enabled HD Graphics 3000.

Thermaltake Commander MS-I


Thermaltake's new Commander MS-I is the latest eSPORTS chassis for enthusiasts with a pretty affordable price (just $49.99).

It features a side window, a bottom-mounted PSU area, a black-tinted motherboard tray with cut-outs for cable management and behind the CPU socket, support for graphics cards as long as 12.5", a 120-mm silent LED fan at the back, and a multitude of tool-less drive bays. Three 5.25" bays and one 3.5" bay face the outside of the case, while an additional five 3.5" bays and one 2.5" bay can play host to your hard drives and SSDs. Built-in latest USB3.0 SuperSpeed connector (for VN400A1W2N only).
