The x86 Power Myth Busted: In-Depth Clover Trail Power Analysisby Anand Lal Shimpi on December 24, 2012 5:00 PM EST
I also included Principled Technologies' new HTML5/js web test suite WebXPRT in our power analysis. Like the rest of the tests, Intel already outperforms NVIDIA here but does so with lower power consumption. A big part of the advantage continues to be lower power consumption on the GPU rail, surprisingly enough.
As our first native client test, we turned to PT's TouchXPRT 2013. As there is no "run-all" functionality in the TouchXPRT benchmark, we had to present individual power curves for each benchmark. The story told here is really more of the same. On the CPU side, Intel is able to deliver better performance at lower power consumption. On the GPU side, performance is good enough for these tasks but once again, is delivered at lower power consumption.
