Socket FM2, A85X Chipset, Test Specs

As excited as we are for the new Trinity APUs, we canít help but be disappointed that they require a new socket that isn't backwards compatible -- unlike what we have seen with the AM2/AM2+ and AM3. Although the FM1 and the new FM2 sockets look very similar, they aren't pin compatible, so users currently working with Socket-FM1 systems are unable to upgrade to Trinity without having to replace their motherboard as well.

Whereas the FM1 socket only saw a single generation of APUs, we believe AMD is going to release at least one more generation after Trinity for the FM2 platform, which makes investing in it a lot safer for budget users.

Although the FM1 and FM2 sockets aren't compatible, you will still find FM2 boards using the existing A55 and A75 chipsets. Given that the features offered by these two chipsets are still very current, such as full SATA 6Gb/s support and native USB 3.0 for the A75, it makes sense for AMD to carry them over. However, AMD has also developed a new performance-orientated chipset known as the A85X which most notably brings Crossfire support to the table.

Additionally, compared to the A75, the new A85X chipset also delivers two more SATA 6Gb/s ports for a grand total of eight. USB support remains the same as the A75, leaving the A85X with four USB 3.0 ports, ten USB 2.0 ports and a pair of older USB 1.1 ports.
