CPU is Intel Core i3-3220, most entry Ivy Bridge so far.
The clock is 3.3GHz, physical 2 Cores with Hyper-Threading for 4 threads, called 2C4T.
It?s 22nm, TDP 55W and 3MB L3 Cache.

System Performance Test
CPU 99.8 X 32 => 3292.41MHz
DDR3 1796 CL9 10-9-27 2T

Hyper PI 32M X4 => 14m 14.585s
CPUMARK 99 => 514


Nuclearus Multi Core => 14268
Fritz Chess Benchmark => 13.29/6378


CrystalMark 2004R3 => 191818


CINEBENCH R11.5
CPU => 3.17 pts
CPU(Single Core) => 1.32 pts


PCMARK7 => 3099


Windows8 Experience Index - CPU 7.2


Core i3-3220 single thread performance is very high. 2C4T structure also works well for multi-tasking.
If you have higher performance demand for file converting or graphics related applications, you can consider Core i5 or i7 CPU. It will improve the performance.

DRAM Test
DDR3 1796 CL9 10-9-27 2T
ADIA64 Memory Read - 18452 MB/s
Sandra Memory Bandwidth - 22463 MB/s
MaXXMEM Memory-Copy - 19663 MB/s


DDR3 1995.4 CL9 11-10-27 1T
ADIA64 Memory Read - 19416 MB/s
Sandra Memory Bandwidth - 25345 MB/s
MaXXMEM Memory-Copy - 20886 MB/s


Ivr Bridge Momory Controller improves a lot. B75 chip can reach DDR3 2000.
Previous Sandy Bridge CPU with entry chipset only supported DDR3 1066~1333.
Comparing Intel two generations, DDR3 clock improves a lot. The bandwidth increases 25%.

Temperature (Room is 19)
Enter to OS Desktop - 26~28


CPU Full Speed - 47~49
LinX 0.6.4


The test above is using Intel original cooler. The result is quite good already.
22nm is another Ivy Bridge advantage. Core i3-3220 temperature is quite low in default clock.
If installing in chassis, I estimate the temperature will rise 5~8 degree C more which is still acceptable.
