Memory tests
Nothing much in memory bandwidth on these two differing platforms and form factors, according to ScienceMark 2.0.
Of course, an S939 system's strongpoint is in lack of memory latency. Lower memory latencies, say, 2-2-2-5 1T, would push the result to <50ns.
Near-identical performance from the 18KG Dell monster and the svelte MV Cubik GamePro.
