AMD A85X Platform
The Second Generation of AMD A-Series processors also comes with a new platform; the A85X. Socket FM1 motherboards came in one of two varieties, A75 and A55. Both of these chipsets will also be available with the FM2 socket. Additionally, the A85X chipset will also sport the FM2 socket. The FM2 socket knocks one pin off the 905-pin FM1 socket. The 904-pin lidded micro-PGA socket FM2 measures the same size as the FM1, however, at 40mm X 40mm. Luckily, this means that your AM2, AM2+, AM3, AM3+, and FM1 heatsink and fan assemblies.
In reality, the A85X Platform changes little. The key difference bet the A85X and the A75 chipsets is the number of SATA and USB 3.0 ports it natively supports. The A85X supports eight SATA 6Gb/s ports and four USB 3.0 ports. Granted, the A75 supports four USB 3.0 ports as well, but the A55 chipset doesn't support any at all.
Another feature that the A85X adds to the table is the ability to run two discrete GPUs in a CrossFire configuration. You can run a single discrete card at x16 or two at x8. Of course, the socket FM2 APUs already come with a decent GPU on-die. If you need something more powerful, it would probably be easier to buy a discrete Radeon HD 6000 or 7000 series GPU and pair in CrossFireX with the on-die GPU.
Of course, many motherboard manufacturers might make it even easier for you by adding Lucidlogix Virtu like you see in the Z77 motherboards. The motherboard we received to go with the two new Trinity APUs was the Gigabyte GA-F2A85X-UP4. Don't worry, you'll be able to read all about the GA-F2A85X-UP4 very soon. I wish I could have included more here, but with less than two days, I couldn't have done it justice.
