AMD launched Llano APU with FM1 socket in July 2011.
Later on, AMD launched Socket FM2 in Oct 2012.
FM2 and FM1 CPU sockets are not compatible. Please be aware of it before upgrade.
In the past, the advantage of AMD platform was compatible sockets. Itís too fast for this transition.
FM2 code is Trinity APU. It combines AMD AM3+ Bulldozer structure.
The price is lower to make APU platform parity.
Chipset can use A75 and A55, but supports FM2 Socket.
AMD also launched a new chipset for Trinity APU, more high end A85X.
CPU is current most high end Trinity APU, A10-5800K.
32nm, 4-Cores, 3.8GHz, Turbo Core to 4.2GHz
Max TDP is 100W and built-in GPU is AMD Radeon HD 7660D
FM1 and FM2 CPU are 32nm which is no improvement in manufacturing.
FM2 socket is 904Pin and FM1 is 905Pin.
There is one pin less as you can see in pic.
MB is GIGABYTE most high end for FM2 Socket, F2A85X-UP4
The price is just a little bit higher than A10-5800K. Building high end FM2 platform is not too costive.
Itís black and gray as main design of GIGABYTE high end MB.
Itís own durable design. Blink of an eye, itís 5th generation.
2oz PCB and 60A Ferrite core choke and latest IR3550 PowIRstage chip.

Upper-left is 8Pin power connector. FM2 socket supports AMD A and Athlon series CPU
Red button is power, blue is Reset and black is Clear CMOS.
FM2 5800K clock after OC is much higher than FM1 3850.
As 5800K using dual module quad core structure, the clock and OC ability are improved a lot.
If we just look at performance in CINEBENCH, the CPU single and multiple threads numbers are as below.
FM2 5800K OC 4492MHz and i3-3220 default 3293MHz.
i3-3220 Single Core CPU is 26.2% higher, and 5800K multi-CPU is 14.5% higher.
FM2 5800K OC 4492MHz and FM1 3850 OC 3540MHz
3850 Single Core CPU is 14.8% higher and 5800K multi-CPU is 7.4% more.
As multi-tasking Fritz Chess Benchmark, these 3 CPUs performance is similar.
Itís up to your requirement to decide which one is more suitable for you.
FM2 default clock can pull to 2133 which is higher than FM1 1866.
In ADIA64 Memory Read, the bandwidth increases 20%.
However, in Sandra and MaXXMEM, itís lower than FM1.
As new structure characteristic and bandwidth performance, you can decide by high clock or bandwidth.
3D Performance Test
Built-in AMD Radeon HD 7660D
3DMark Vantage => P6155
StreetFighter IV Benchmark
1920 X 1080 => 71.70 FPS
3DMark Vantage is 20% higher than previous Radeon HD 6550D with 3850.
StreetFighter IV Benchmark and FINAL FANTASY XIV performance is similar.
However, Unigine Heaven Benchmark test DX11, itís almost double the 3D performance.
5800K built-in AMD current most high end Radeon HD 7660D, the 3D performance is excellent.
This is the advantage of AMD APU platform. Itís designed for pull high built-in 3D performance for entry 3D demand users.
SSD is CORSAIR Force GS 240GB
AS SSD Benchmark - 719
Seq Read - 524.01 MB/s Write - 270.50 MB/s
4K - 64Thrd Read - 214.89 MB/s Write - 194.63 MB/s
ATTO DISK Benchmark over 512KB test can reach 540.5 Mb/s read and 517.5 MB/s write.
SSD Benchmark TOTAL => 4020.13
Trinity APU latest A85X chipset supports 8 native SATA3 ports.
For users who own many HDD o SSD, the transfer rate is a key factor.
In the past, AMD SATA transfer rate is not as good as Intel. However, it improves step by step.
Form the test above, you can see overall read/write performance and 4K - 64Thrd are both in good level.
However, for 4K read/write performance is only 50~60% of Intel chipset. It must improve in the future.
Also as SSD Raid 0 Trim technology and performance, I hope AMD new chipset can catch up as well.
Temperature(Room is 22˚C)
Enter to OS Desktop - 40
CPU Full Speed - 55
Disabling AMD C&Q power saving feature do testing. 32nm APU and FX CPU are low temperature in most software.
Sometimes, even lower than room temperature, like 8~16. As CPU is not thermoelectric Cooling, it should be higher than room after power on.
Itís impossible numbers, so just ignore the AIDA.
As EasyTune6, CPU temperature is 55 as full speed which is quite good with mid end cooler.
As 32nm, the temperature performance is good. I recommend you to use MB bundle software or UEFI BIOS to check the accurate temperature.
CPU and GPU both Full Speed - 183W
OCCT Power Supply Test
Even disable AMD C&Q power saving technology, itís only 44W as OC to 4.5GHz.
CPU full speed is 165W which still too high. GPU full speed only increase 18W is very good.
Power consumption is weakness for AMD. Finally, it moves to 32nm, but the power consumption doesnít decrease efficiently.
1. Black PCB with good quality. Trinity APU structure makes high end MB parity.
2. Using IR3550 PowlRstage PWM to lower MOSFET tmeperature
3. 7 SATA3 and 1 eSATA3 for better expandability
4. IO has 4 different video output ports and supports 4 USB 3.0 devices
5. Build in debug LED and 3 buttons for bare system users
1. CPU full speed power consumption is too high
2. Better to have 2 PCI slots
As the test above, you can see the difference between FM2 Trinity APU and FM1 Llano APU.
Trinity APU advantage is CPU clock can pull high and DDR3 clock is one level higher as well.
Temperature and power consumption are similar as they are both 32nm.
5800K built-in 3D performance improves a lot, especially in DX11 supported games.
Latest Trinity APU still focus in mid to low end market to provide more parity options.
New chipset specs are better than A75 and supporting more SATA3.
If you own FM1 already, you donít really need to upgrade to FM2.
If you are planning to buy a new entry PC and require 3D performance more than CPU, Trinity APU can be a good choice for you
