The arithmetic tests in Sandra 2004 have always seemed to favor Intel’s NetBurst architecture. The Gallatin-based Extreme Edition responds very well to the first of three standard Sandra 2004 benchmarks, as AMD’s entire processor lineup lags behind significantly.
The difference between Intel’s NetBurst and the AMD64 architecture is much more pronounced in the multimedia test, where the Pentium 4 processor proves its SSE2 alacrity.
Sandra’s memory bandwidth test naturally favors the Athlon 64 FX-53, which benefits from its integrated memory controller and dual-channel memory bus. The Pentium 4 processor follows by about one gigabyte per second, while the Socket 754 Athlon 64 3400+ comprises the rear, limited by its single-channel bus.
