The situation in rendering applications is quite natural. Processor clock frequency determines the performance results here.
Scientific Calculations
Athlon 64 X2 processors have always been famous for their high results in ScienceMark 2.0 test measuring the systems performance when working with molecular dynamics algorithms. As for Core 2 Duo processors, their results in this test are quite logical and do not need any additional explanations. By the way, I would also like to point out that the model numbering of the dual-core processor solutions proved highly adequate. They reflect the relative Core 2 Duo processors performance very precisely almost all the time.
