OS: Windows7 Ultimate 64bit SP1
CPU Default Performance Test
CPU 100.0 X 29 => 2900.4MHz
DDR3 1866.8 CL8 9-7-27 1T
Hyper PI 32M X 4 => 23m 00.134s

CPU(Single Core) => 0.88 pts
PCMark Vantage => 12700
Windows Experience Index - CPU 7.3
The A8-3850’s performance is little changed from the previous generation Phenom II, even when the CPU cache sizes of both L2 and L3 are slightly different.
For those who need quad-core CPU performance, AMD offers better cost to performance,
but regarding the single-thread performance of AMD CPUs, I still feel that in the future, AMD still has a lot of room to improve
DRAM Bandwidth
DDR3 1866.8 CL8 9-7-27 1T
ADIA64 Memory Read - 9360 MB/s
Sandra Memory Bandwidth - 15775 MB/s
MaXXMEM Memory-Copy - 10680 MB/s
This is where the Llano APU platform has made progress. The CPU default is adjustable up to DDR3 1866, which is a bit higher than the previous 1600 platform.
While the bandwidth and their platform have made a bit more progress, compared with rivals such as the Sandy Bridge platform, the bandwidth seems to be lagging further behind ...
DDR3 bandwidth is where AMD needs to improve in the future, and we hope that performance will improve with the launch of the Bulldozer
Temperature Performance (room temperature about 26 degrees)
Standby - 18
CPU at Full Speed - 39
LinX 0.6.4
In a test of the AMD C&Q power-saving technology, in standby the CPU clock / voltage drops significantly, and for this reason the temperature falls quite a bit
At this point, the obtained data was quite good, and even at full speed it was only 39 degrees.
However, because the chips tested for temperature on each motherboard were different, actual temperatures may have been higher for some.
But what is certain is that AMD used 32nm for the A8-3850, so there has been some progress with the temperature performance of the AMD platform -

Power Consumption
Standby - 27W
CPU Full Speed - 125W
LinX 0.6.4
Both the CPU and the GPU simultaneously at full speed - 153W
With OCCT running, a test of the power supply
In standby mode, because of the AMD C&Q power-saving technology, power consumption is reduced to only 27W
With the Llano APU platform, the main power consumer is the CPU. At full speed, there is an increase of about 98W in CPU power consumption
In addition, following our comparisons, we believe that the ECS had more outstanding power performance,
and the A75F-A was about 10-20W lower than the previously used A75 platform
3D Test
Internal AMD Radeon HD6550D display driver
3DMark Vantage => P4423
StreetFighter IV Benchmark
1920 X 1080 => 57.58 FPS
FINAL FANTASY XIV
1920 X 1080 => 947
Built-in 3D performance is the biggest advantage of this platform, and the largest factor boosting the performance level is the DDR3 clock
When combined with top of the line DDR3, taking the setting to 1866 will result in a significant 3D performance boost
The above test data showed the internal 3D almost on a par with the nVIDIA GT430, and slightly better than the AMD Radeon HD5570
Consumers who want to buy entry-level VGA should save their budget with this expenditure
ECS brought the BIOS interface to the UEFI, and this new specification is what most of the motherboard brands have pursued in 2011

In the middle are current parameters for the DRAM
Below are the CPU FSB overclocking settings. This has a very significant impact on the Llano APU

Re: Another overclocking breakthrogh - ECS A75F-A Motherbaord
VDIMM Voltage -300~+600 mV
NB Voltage +10~+360 mV
DDR3 Frequency Options
Built-in GPU that can share main memory capacity of 64M - 2GB
Hardware Status
Added Smart Fan speed control function
Details about overclocking have been mentioned previously.
When the Llano APU pulls the CPU to a higher clock, the SATA FSB will be pulled up at the same time
For an extended time under 100MHz non-overclocked conditions, the stability of the SATA device may be uncertain
This occurs with the entire A75/A55 series under overclocking conditions, and this is an inherent physical limitation in AMD’s design
For a wide range of users who want to overclock the CPU, we recommend that you wait for the launch of CPUs that are not locked.
Increasing the multiplier is a better solution for overclocking
With the AMD Llano APU, overclocking settings are a bit simpler
Just pull up the CPU FSB and combine that with the appropriate voltage to achieve overclocking results
Of course, you’ll need to choose the right DRAM to effectively and simultaneously boost DDR3 and GPU performance
Above are the overclocking settings from windwithme for the A75F-A for use as reference
Overclocking Performance Test (SATA to IDE mode)
CPU 122.0 X 29 => 3539.4MHz
DDR3 2278.4 CL10 11-10-27 1T
Hyper PI 32M X 4 => 19m 01.017s
CPUMARK 99 => 510
Nuclearus Multi Core => 15036
Fritz Chess Benchmark => 18.07/8671
CrystalMark 2004R3 => 235011
CINEBENCH R11.5
CPU => 4.18 pts
CPU(Single Core) => 1.07 pts
PCMark Vantage => 14304
Windows Experience Index - CPU 7.4
When the A8-3850 overclocked from 2900MHz to 3540MHz, the CPU performance increase was about 20%
Compared with the 32nm process CPU, overclocking added about 1.45V to the required voltage.
This relationship between the clock and voltage did not result in significant progress.
Although the performance of the A8-3850 CPU has been sufficient for most environments, consumers would like to see more progress with the new architectureComment
