intro 3 way AMD A75/A55 Llano motherboard shootout

Today we take a look at three different Llano boards through the entire range of the AMD Fusion Lynx platform. The Asus F1A75-V Pro, Gigabyte A75M-UD2H and ECS A55F-A are put under the microscope and through the tests to determine not only which comes out on top, but also which fits your needs best.

AMD introduced their Lynx platform with the A75 chipset a few months ago, and since then they have also released the toned down A55 chipset aimed at builders on a budget. The most impressive aspect of the Lynx platform is its ability to house a DX11 capable GPU on-die with 4 real processor cores, and keep the TDP under 100W. Today we will take a look at three boards in three different prices ranges, two are A75 chipset motherboards and one is an A55 chipset board. We will focus on their build quality as well as their performance in various benchmarks. 

Each board also falls into its own price category, ranging from 80 to 130 USD. 

First let’s look at the Lynx platform, as well as the difference between the A75 and A55 FCH (Fusion Controller Hub).

Now in red is what the A55 chipset lacks. This includes the loss of 4 USB 3.0 ports and FIS based switching for RAID arrays. There is also one other major difference, the lack of SATA 6GB/s ports. All of the SATA 6GB/s ports have been toned down to slower SATA 3GB/s ports, which might have an impact on some of the new SATA 6GB/s SSDs which actually take advantage of the higher bus speed. Of course all these downgrades do save the budget minded consumer a good bit of cash. What is most notable about the A75 FCH is its ability to house so many different devices, as well as a consumer IR system which will be great for home theater systems.
