1.Dual spi1M
C2D@3.6Ghz



C2Q@3.6Ghz



See even though the two processors are under same speed, however, quad-core
still got space todeal with super pi 1m, that's why it is faster than dual core 2 seconds.

2.Dual spi32M
C2D@3.6Ghz



C2Q@3.6Ghz



no need to say about 32m, it even fastern than dual core about 30 seconds.

3.Cinebench9.5
C2D@3.6Ghz



C2Q@3.6Ghz



here we can check that out with 3D calculation mode under single core, they both
scaled the same results; but if we use multi-cores to do that, apparently, quad-core would faster than dual-core about 100%.

How about Sandra some benchmarks?
CPU Test1 ; C2D @3.6ghz:



C2Q@3.6Ghz



CPU Test1 ,the score from quad core is 100% off dual core

CPU Test 2
C2D@3.6Ghz



C2Q@3.6Ghz




CPU Test 2,Quad-Core is still about 100% off dual core

how about Memory Bandwidth?
C2D@3.6Ghz



C2Q@3.6Ghz



Dual Core 2DIMM seems larger than quad-core 4DIMM about 100MB/S

L2 Cache

C2D@3.6Ghz



C2Q@3.6Ghz



L2 Cache quad-core 8mb cache under the additional 63% of bandwidth, the speed
is also 100% off dual core.

WinRAR seems like doesn't support multi-tasking, but under the same condition for compressing
32mb folder, quad-core still won over about 7 seconds.

TMPEG supports Multi-Tasking, for the same work of converting 2 files, Quad-Core certainly won over dual core without any problem.
