Just published another benchmark app for Android. It is a memory bandwidth benchmark derived from the STREAM benchmark.
My benchmark, named RgBandwidth, is meant to provide you with a rough estimate of the achievable memory bandwidth on your system. Get it from the Play store. To quickly get an estimate of memory bandwidth performance achievable on your device, just press “Run” using the Auto mode.
Then in about 10-20 seconds, you will get various bandwidth ratings in MB/s. The easiest to understand is the Copy Bandwidth data. Alternately, you can manually select a thread number and experiment around.
On my dual-core Snapdragon S3 device, I got about 1.5GB/s of peak bandwidth.
If you use my benchmark, I would be very grateful if you could share the numbers with me in the comments below 🙂
