To create the baseline I performed a fresh install of Ubuntu 14.04 to eMMC on each device and upgraded each to the latest available packages:
The tests I've chosen aim to show CPU, RAM and I/O performance and include:
- CacheBench – Memory and cache bandwidth performance benchmark.
- CLOMP – C version of the Livermore OpenMP benchmark developed to measure OpenMP overheads and other performance impacts due to threading.
- 7-Zip compression – Uses p7zip integrated benchmark feature.
- dcraw – This test measures the time it takes to convert several high-resolution RAW NEF image files to PPM image format using dcraw.
- LAME MP3 encoding – This test measures the time required to encode a WAV file to MP3 format.
- FFmpeg – Audio/video encoding performance benchmark.
- GMPbench – Test of the GMP 5.0.3 math library
- OpenSSL – Measures RSA 4096-bit performance of OpenSSL.
- PHPBench – Benchmark suite for PHP.
- PyBench – Python benchmark suite.
- SQLite – This test measures the time to perform a pre-defined number of insertions on an indexed database
- Stream – This benchmark tests the system memory (RAM) performance.
- TSCP – Performance benchmark built-in Tom Kerrigan’s Simple Chess Program.
- Unpacking the Linux kernel – This test measures the time it takes to extract the .tar.bz2 Linux kernel package.
- IOzone – This benchmark tests the hard disk drive / file-system performance.
show just how more powerful the latest Core M device is.
The following is a brief video showing basic system information about Ubuntu 14.04 as installed on this latest Core M Intel Compute Stick (STK2M3W64CC) together with a demonstration of booting the latest "Ubuntu 16.04 (Xenial Xerus) Daily Build" ISO direct from eMMC as described in http://www.linuxium.com.au/how-tos/simplewaytobootanisoinwindowsorubuntuwithouttheneedforexternalmedia
