AMD launched new APU structure, FM1 platform in July 2011. 6 months passed, there are only A75 and A55 chipsets support FM1 platform. However, FM1 CPU is getting more and more. Mainly it’s for mid to low market. The C/P is quite well. FM1 has X4/6 series as 4 Cores or K series for OC market. The main strength for FM1 platform is 3D performance of APU structure. How to pick higher built-in 3D graphic and CPU performance is key subject for selecting APU. Even though it’s an entry level product, the balance between built-in 3D graphic and CPU performance is important. Finally, I decide to buy AMD A6-3500, triple cores, and AMD HD6530D. I didn’t buy most entry A4-3300, because it’s only dual cores and HD6410Dis lower spec. As using A6-3500, more CPU cores can compensate the performance and the 3D performance is higher. Inside Box Product manual, sticker, cooler, and AMD A6-3500. FM1 CPU pins are complete different with AM3+. A55 chipset has no USB3.0 and SATA3 comparing to A75. For normal users or word process machine, A55 is enough. If you have more budget, you also can consider A75. This review I use GIGABYTE A55M-S2H, the form factor is Micro ATX. All solid caps for entry MB is regular components now. Also, it has GIGABYTE exclusive Super4 technology. Recently, it launched 4 years warrant which is conversed operation as 3C products is reducing their warranty. Lower-Left Corner 2 X PCI-E X16, first is X16 and second is X4. It supports AMD Dual Graphics. 1 X PCI-E X1 1 X PCI Realtek ALC889 Audio chip supports 7.1 channels and High Definition Audio. Realtek RTL8111E LAN chip and black connector is TPM module slot. Lower-Right Corner 6 X Blue SATA, provided by A55. It’s SATA2 and supports RAID 0, RAID 1, RAID 10 and JBOD. There are two front USB 2.0 in left and right is DualBIOS. Upper-Right Corner 2 X DIMM DDR3 support 1066/1333/1600/1866/2400(OC). DDR3 max capacity is 32GB. Next is 24-PIN power connector. Upper-Left Corner AMD CPU Socket FM1. It’s compatible with AM2/AM3 cooler. CPU uses 4+1 phases PWM. Upper left is 4Pin power in.
