In this paper, we selected three different CPU architectures for performance analysis: single-core, dual-core and hyper-threading CPU's. Four kinds of operations are executed on these architectures. After analyzing all the data, we found that the single-core and dual-core act as usually expected: the execution times of combined operations are very close to the sum of that of compounding operations. In contrast, the hyper-threading CPU shows better performance when each thread performs specific operations, rather than mixed operations.
