Benchmark Results: Synthetics
As we start in with our synthetics, the differences between these two mobile platforms is immediately apparent. The PCMark Vantage Overall suite score quite obviously favors Intel’s Arrandale processor. The Memories, TV and Movies, and Productivity suite scores follow suit, though not quite to the same degree.
We already know that there’s often little correlation between synthetic measurements of arithmetic/multimedia performance and real-world metrics. But Sandra 2010 nevertheless demonstrates a notable advantage in favor of Intel’s Arrandale-based Core i5-540M.
Most interesting is the memory bandwidth, which tells us that the on-package memory controller is enabling significantly more throughput than GM45’s memory controller. Of course, this is less bandwidth than you’d get from the Mobile Core i7-920XM, which includes an on-die (versus on-package) memory controller.
