android prime vs prime prime speed - ji3m - 11-24-2015 08:54 PM
Just ran some speed comparisons android prime and real prime Androids were tab pro 8.4, note 2 and Blue Stage 7 (cheap tab). In all cases the droids were about 3x faster. Of course they are quad cpus over 1ghz But it shows that the android prime is a native app and very well implemented. The test was a simple loop expanding and then factoring a cubic about 5000 times.

What criteria were adopted to get those speed ratios? RE: android prime vs prime prime speed - ji3m - 11-24-2015 09:16 PM
No critetia , just a time measurement og loop () begin local t:= TICKS, Q, k; for k from 1 to 5000 do Q:= expand ((x+1)*(x-2)*(x+9)) ; factor (Q); end; TICKS-t; end; Run on each device and compared times. Nothing fancy. RE: android prime vs prime prime speed - Fortin - 11-25-2015 02:23 PM
Be aware that there is approximately a 20% performance hit during key presses. So if your runs are in the < 200ms range on the HW, then lingering on the enter key can be a significant variable in the processing time. RE: android prime vs prime prime speed - ji3m - 11-25-2015 03:06 PM
Runs over 10 seconds This test is just rough. Im sure there might be a dependency on what is computed but it should be the same code base. I dont care about absolute time but just relative between devices How well does the windows version do? I havent tried this . |
