Overclocking performance testing:
CPU 300 X 12.5 => 3750.2MHz
DDR3 1600 CL7 7-7-21 1T
VGA 1009MHz

Hyper 4 X PI 32M=> 20m 42.477s
CPUMARK 99=> 496


Nuclearus Multi Core => 16524
Fritz Chess Benchmark => 19.06/9150


CrystalMark 2004R3 => 212111


CINEBENCH R11.5
CPU => 3.26 pts
CPU(Single Core) => 1.13 pts


PCMark Vantage => 11667


Due to the differences of every testing software, 910e, after overclocked to 3750MHz, has 20~30% performance improved.
C3 process has been adopted, so DRAM arguments are better; besides, the whole clock can be overclocked more 100~200MHz.

3DMARK2006 => 2547


StreetFighter IV Benchmark
1024 X 768 => 30.10FPS


Biohazard5 Benchmark
800 X 600 => 17.6 fps


The advantage of HD4290 is that CPU can be overclocked higher clock, and it is not necessary to add too much voltage to make the CPU reach 1009MHz.
About the result of 3DMARK2006, compared with that of HD 4200, the 3D performance of HD4290 has 10~15% improved.
As to Biohazard5 needing higher 3D ability, it is suggested to add extra VGA to make the game run more fluently.

DDR3 bandwidth testing:
Default CPU Frequency: 2600Mhz
DRAM DDR3 1600 CL7 7-7-21 1T
Sandra Memory Bandwidth - 12525 MB/s
EVEREST Memory Read - 8976 MB/s


Default CPU Frequency: 3750Mhz
DRAM DDR3 1600 CL7 7-7-21 1T
Sandra Memory Bandwidth - 13513 MB/s
EVEREST Memory Read - 9526 MB/s


DDR3 performance of AM3 structure is so-so, bandwidth performance is just ok. As for DDR3 frequency,
the frequency was limited about 1600~1700, and some 890GX/890FX MB of the new generation performs over DDR3 1800.
It is judged that AMD wants to improve DDR3 frequency first, hoping to improve DDR3 bandwidth performance with new structure in future.
