DDR3 1947 CL8 10-8-27 1T
ADIA64 Memory Read - 10971 MB/s
Sandra Memory Bandwidth - 18509 MB/s
MaXXMEM Memory-Copy - 13163 MB/s


Increasing the CPU frequency causes the new FM1 platform to increase the bandwidth for the DDR3 as well.
However, the increased performance is only about 500 MB/s, which is exactly the required enhancement for AMD architecture.
When the overclocking is close to DDR3 1947, it can offer nearly 11000 MB/s bandwidth, which is relatively good for the AMD platform.
The overclocking range of the DDR3 is also increased in the FM1 platform which is normally between 1650-1800 on the AMD platform.

Temperature performance (ambient temperature is about 32 Celsius. )
System standby - 13~16


CPU full speed - 55
Intel Burn Test v2.4,Stress Level Maximum


Test with the AMD C&Q power-saving technology turned on.
The CPU frequency is greatly reduced when the system is on stand-by therefore the temperature is much lower.
When the CPU is at full speed while working with an advanced heat sink, the temperature is acceptable at around 55 Celsius .
I hope that AMD can attain the 32nm process in its CPU series in the future, so as to help increase its competitiveness.

Power consumption test
System standby - 28W


CPU and GPU at full speed - 178W
Power Supply test in OCCT


When the system is on stand-by, power consumption is quite satisfactory due to the power-saving feature.
On the other hand, when at full speed, power consumption is still high.
The 178W-power consumption at full speed is primarily caused by the CPU. This is not good since it adopts a 32nm process.
Compare this with previous tests. The power consumption of Intelís 32nm CPU at full speed is a dozen watts less than that of the A8-3850.
Power consumption is another aspect that AMD needs to improve on in the future.
It takes a long time to realize the 32nm process, and power consumption could not be reduced effectively.

3D test
Internal display AMD Radeon HD6550D
3DMark Vantage => P5216


StreetFighter IV Benchmark
1280 X 720 => 109.58 FPS


Unigine Heaven Benchmark => 15.3 FPS


In my previous article, I shared the test data of CPU/DDR3 with 100/1866 ratio, and the 3DMark Vantage was about P4500.
This score has reached the same level as the nVIDIA GT430, and it is 10% better than the Radeon HD5570 under the same brand.
In this test, it works with CPU overclocking, so as to increase overall 3D performance by 10~20%.
According to the Llano APU data posted on the internet, the 3DMark Vantage can achieve nearly P7000 at most, which has an amazing 3D internal display performance.

Video Playback Testing
Start up it to play the original copy of a Blu-ray video on hand Ėnamed Inception.
Below is the publishing corporationís copyright ownership.
PowerDVD 10 software
Starting menu
Until now, the CPU occupancy rate is as low as 1-6%.


Playing process
The CPU occupancy rate is 2-10%.


The A8-3850 internal display is represented by the Radeon HD6550D, which is capable of playing 1080P videos.
Generally, the new generation Intel Sandy Bridge and AMD Llano APU have integrated the internal display function to usher in a new era of technology.
Aside from multiplying 3D performance several times, the CPU occupancy rate is much lower than the old platform when playing high-definition videos.
In the future, you need not worry about lagging problems when selecting the internal display platform for playing videos.
