Memory and Physical Disk Tests
In terms of CPU arithmetic performance, the Core M 5Y70 in the Yoga 3 Pro is an interesting beast. It drops in just a hair behind a Core i3 dual-core with Hyperthreading and a 3GHz clock speed, though this Core M chip tops out at 2.6GHz with HT enabled. The Core M's integer and float performance in the Multimedia test, on the other hand, actually bests a Core i5 650 dual-core chip. Finally, the Core M 5Y70 offers a very respectable 18GB/sec of aggregate memory bandwidth. In addition, Lenovo's choice of SSD has proven sound as well with the 256GB LiteOn drive showing north of 500MB/sec throughput.

Unlike many widely available JavaScript benchmarks, this test is:
Real World - This test mostly avoids microbenchmarks, and tries to focus on the kinds of actual problems developers solve with JavaScript today, and the problems they may want to tackle in the future as the language gets faster. This includes tests to generate a tagcloud from JSON input, a 3D raytracer, cryptography tests, code decompression, and many more examples.
Balanced - This test is balanced between different areas of the language and different types of code. It's not all math, all string processing, or all timing simple loops. In addition to having tests in many categories, the individual tests were balanced to take similar amounts of time on currently shipping versions of popular browsers.
Statistically Sound - One of the challenges of benchmarking is knowing how much noise you have in your measurements. This benchmark runs each test multiple times and determines an error range (technically, a 95% confidence interval).
