Using the latest Sisoft Sandra 2009 SP2 software we got a quick idea about the processing power of the Intel Dual Atom processor, against the single-core Atom and various other processors.

Summarizing the test results, we can say that the Intel Dual Atom processor is slightly faster than the single-core Intel Atom processor, by almost 10-15%. The Intel C2D CPUs are much faster in all tests, although they run at lower speeds.

The red color represents the Shuttle X27D test system:

Featuring two cores, the Atom CPU 330 gave good results in the ALU Power Performance:

While, it gave almost the same performance with the single Intel Atom processor at the Cryptographic Benchmark test.

The dual-core Atom CPU was actually slower than its single-core brother in the memory reading tests (Everest Ultimate Edition). . That can be explained due to the fact that the 533FSB is divided at half for each core

At the memory write/copy tests, both systems have identical performance

In the CPU tests, the the dual cores showed good performance, at least compared with the single core processor:

(CPU Queen Test)

(CPU PhotoWorxx Test)

(CPU ZLib Test)

(CPU AES Tests)

(FPU Julia Test)
