There is a benchmark application out there for just about everything. Using benchmarks, you can measure network speed, processor speed, I/O, memory, SD card read/write times, GPU speed, and all sorts of other things. Being able to view how your device competes on a performance level in real time helps dispel the myths from the facts. There is a new benchmarking application that takes away the flashy, but adds in more stable results.
The application is called RGBenchMark, and it was developed by XDA Forum Member rgbench. It’s also free to download from the Google Play Store. As stated, it’s not as flashy as other benchmarks are, so you won’t be seeing a bunch of bright colors and awesome graphics. What you will find, though, are stable and accurate results. Most likely the best part is that it requires no permissions except preventing phone or tablet from sleeping.
RGBenchMark measure CPU performance in MFLOPS and, according to app reviews, it does so pretty well. As one reviewer described:
Unlike with Linpak, the results do not wildly vary between separate runs. The MFlops result are also directly related to your CPU speed (with half CPU frequency, my score was close to half as well)
If you’d like to give it a shot and see how your results look, you can find out more information at the original thread._________
