Asus Transformer Book T300 Chi 2-in-1 Ultrabook Review

We began our testing of the Asus Transformer Book Chi T300 with SiSoftware's SANDRA 2014 the System ANalyzer, Diagnostic and Reporting Assistant. We ran four of the built-in subsystem tests that partially comprise the SANDRA 2014 suite (CPU Arithmetic, Multimedia, Physical Disks and Memory Bandwidth).

SiSoft SANDRA 2014 System Level Synthetic Benchmark Testing

SANDRA CPU, Multimedia

Memory and Physical Disk Tests

Intel’s Core M 5Y71 performed well in the Processor Arithmetic test. In the Multi-Media benchmark, performance was similar to an Intel Core i5 running at 2.67GHz. Memory bandwidth of the 8GB DDR3L-1600 RAM in the Chi T300 peaked at just over 13GB/s. The internal 128GB SSD put up good numbers in the range of 440MB/s range.

SunSpider JavaScript Processing Test (CPU)

The Webkit Open Source Project suggests the following about the SunSpider JavaScript benchmark:

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).

The Asus Chi T300 ties with the Surface Pro 3 for the top spot in our SunSpider test. Both of these processors are clocked at 2.9GHz, though the Chi T300 uses Intel’s Core M 5Y71 processor while the Surface Pro 3 utilizes an Intel Core i5-4300U processor.
