The Socket FM1 was released in mid-2011 for the A-series Fusion (Llano) processors and Llano-derived Athlon II processors. It was designed to be used with the AMD Fusion Family 12h microarchitecture, called Llano popularly. It is an evolution of the K10 design featuring a 1MB L2 cache per core, and no L3 cache. It has an improved hardware prefetcher, a redesigned memory controller, power-saving improvements including clock gating, and Onion and Garlic interfaces for interfacing with an on-die GPU. It is also used to make a great Italian meatball and pasta dish, from the sound of it. Here is some of the perks of owning one of these CPUs:
- All models feature upgraded Stars (Mobile Phenom II architecture) CPU cores (Husky) with no L3 cache, and with Evergreen family graphics, specifically Redwood-class integrated graphics on die (WinterPark for the dual-core variants and BeaverCreek for the quad-core variants).
- All models are manufactured on GlobalFoundries’ 32nm SOI process.
- All Lynx desktop models support up to 4 DIMMs of DDR3-1866 memory and Sabine mobile models support up to 2 DIMMs of DDR3-1333 / DDR3-1600 dual-channel memory.
- All models feature UVD3 for hardware video decoding, including 120Hz stereoscopic 3D support.
- All models have an integrated PCIe 2.0 controller.
- Select models support AMD’s Turbo Core technology for faster CPU operation when the thermal specification permits.
- Select models support Hybrid Graphics technology to assist a discrete Radeon HD 6450, 6570, or 6670 discrete graphics card. This is similar to the Hybrid CrossFireX technology.
And here is a list of supported processors:
