A recent report by ABI research showed Intel's Clover Trail+ outperforming SoCs from Samsung, Qualcomm and Nvidia.
However, a EETimes article casts serious doubt about the validity of the report, in particular the AnTuTu benchmark used to test the chips.
"Going from the 2.9.3 version of the AnTuTu benchmark to the 3.3 version, the overall AnTuTu scores increased 122 percent, and the RAM score increased 292 percent for the Intel processor, while the scores for the Samsung processor increased only 59 percent and 53 "
To top things off, somebody analyzed the assembler code in the AnTuTu benchmark and found clear evidence that the benchmark had been tweaked to favour x86 processors.

In November last year Chrome overtook Firefox in market share for the first time. What people don’t realise is that the release of Firefox 4 caused a large part of the decline.
Firefox 4 was a major new release and came with a brand new Javascript engine and HTML5 parser. Unfortunately, these new features came with major memory leaks and performance bugs. The result was that if you used Firefox 4 for an extended period of time the browser would eventually become unresponsive, making it virtually unusable.
