Windows on ARMIntel is trying as hard as it can to promote its Atom processors for tablet use, and recently the Santa Clara chip giant unveiled a series of benchmark that compare its single-core Z670 CPU with a dual-core ARM-based SoC, the Intel chip proving to be faster than its counterpart in all tests run.


Both chips were running the 3.1 version of the Android mobile operating system, also known as Honeycomb, and the ARM powered tablet was based on an Nvidia Tegra 250 SoC, which relies on two 1GHz Cortex A9 cores.

From the benchmarks provided by Intel, the Atom processor was faster in almost all the scenarios that were run.

The biggest difference between the two solutions was recorded in the SunSpider JavaScript benchmark (a test designed to find out the JavaScript performance of the system), where the Intel CPU managed to lead the ARM-based chip by 70 to 80 percent.
