ARM Outmuscles Atom on Benchmark-April 12, 2010 |
ARM—and, for that matter, MIPS—CPUs outperform Intel’s Atom, at least as measured by the CoreMark benchmark when normalized for frequency. ARM rates its Cortex-A9 at 2.9 CoreMark per MHz (CM/MHz), whereas Atom running a single instance of the benchmark achieves only 1.8 CM/MHz. In fact, all of the single-thread CPUs profiled in Table 1 outperform Atom in terms of per-clock performance.
