Santa Rosa MacBook (November 2007) Benchmarks

Primate Labs posted benchmark results comparing the new Santa Rosa MacBooks that were quietly updated last week to the Santa Rosa chipset along with the new GMA X3100 integrated video card.

In terms of pure processor speed, the MacBook updates seemed negligible (2.0GHz -> 2.0GHz, 2.16GHz -> 2.2GHz), though the underlying bus speed was increased to 800MHz from 667MHz.

The published benchmarks compared the 2.16GHz previous MacBook to the 2.2GHz new MacBook, and did significantly boost memory performance by 15% and stream performance by 25%, reflecting the increased bus speed. Integer, floating point, and overall performance, however, was only marginally improved.

Graphics performance was not tested, but the GMA X3100 should also provide performance boosts over the previous integrated video card (GMA 950).
