Performance during Mathematical Calculations
The newcomer from Intel appeared the fastest Intel CPU in Mathematica 5.1 and MATLAB 7. However, Athlon 64 micro-architecture has more advantages for math1ematical calculations therefore, we cannot announce Pentium 4 670 an indisputable winner here.
The situation turns out slightly different in Sciencemark 2.0. Pentium 4 670 is defeated by Pentium 4 570 although it boasts twice as much L2 cache memory as the latter. The results can be explained by the L2 cache organization in the Prescott-2M core. As we have already mentioned in our article called Intel Pentium 4 6XX and Intel Pentium 4 Extreme Edition 3.73GHz CPU Review, the larger L2 cache of the Prescott-2M core works slightly slower than the cache of the regular Prescott. If it is the performance of the L2 cache memory and not the size that the given application is critical for, then 5XX processors from the Pentium 4 family will appear faster than their 6XX counterparts working at the same clock frequencies.
