Hardware Secrets posted a review on the Gigabyte F2A85X-UP4 Motherboard

The Gigabyte F2A85X-UP4 is a motherboard based on the most high-end chipset for the new FM2 platform, the A85X (codenamed “Hudson D4”). It is targeted to the second-generation APUs from AMD, codenamed “Trinity.” Let’s see what this motherboard has to offer.

APU is a name that AMD coined for their CPUs with integrated video. They are also known as A-series, as models start with the letter “A” (A4, A6, A8, and A10).

There are three chipsets available for the new FM2 platform: A85X, A75, and A55. The A75 and A55 chipsets were released in 2011 with the FM1 platform, which is used by the first-generation of APUs from AMD. The A85X is a new chipset, released with the second-generation APUs. In the table below, we compare the main differences between these three chipsets. As you can see, the main difference between the A85X and the A75 is the addition of two more SATA-600 ports on the A85X.
