Introduction[edit]

This page provides comparison among various TI processors running TI's Android-DevKit. Data published here is for the latest version of released Android-DevKit. Items yet to be measured are marked "TBD" and those that are not applicable to a particular platform are marked "N/A".

Platform Benchmarks[edit]

This is a collection of benchmarks comparing mainly CPU speed and other data transfer operations. In below tests, AM3715@1GHz, BeagleXM@1GHz, and AM3517@600MHz.

RowboPerf: ARM[edit]

See RowboPERF User Guide for more information about these metrics. The RowboPerf application calls native executables compiled with Android's NDK to perform these tests.

Boot Time[edit]

Numbers shown here measure the time from start of loading the kernel image to appearance of Android's Home Screen. These measurements are done using the default (pre-built) images provided with the DevKit. Please note that the very first time you boot your device, the boot time will be significantly higher (approx. 3-4 min).

Time (secs)	AM3715	BeagleXM	AM3517
SD First Boot Time¹	64.8		70.5
SD Boot Time	29.4		32.9

1 First boot time refers to first time the system is booted with a freshly created SD card.

Browser Performance[edit]

Sunspider[edit]

These metrics were collected using the well-known Sunspider performance benchmarks available at http://www2.webkit.org/perf/sunspider-0.9/sunspider.html

Sunspider	AM3715	BeagleXM	AM3517
Total	6826.3 ms +/ - 1%		122777.9ms +/- 1.7%

V8[edit]

These metrics were collected using the v8 performance benchmarks available at http://v8.googlecode.com/svn/data/benchmarks/v6/run.html

V8	AM3715	BeagleXM	AM3517
Total	210		116

AcidTests[edit]

These metrics were collected using the acid browser tests available at http://acid3.acidtests.org/

Acid3	AM3715	BeagleXM	AM3517
Total	93/100		93/100

File Storage Performance[edit]

These tests were performed using the StorageIO application provided in RoboPerf. The application measures the write and read speed of different storage devices using several block sizes. For these tests the file size chosen was 100 MBytes. In order for the application to run the storage device chosen for the test must be mounted in the Android file system and a have read and write access. All the tests were perform on devices with a vfat file system.

MMC/SD Performance[edit]

These tests were performed on a SanDisk 2 GB, class 2, SD card. The third partition "mmcblk0p3" created on a bootable SD card as explained in http://processors.wiki.ti.com/index.php/TI-Android-GingerBread-2.3-DevKit-1.0_UserGuide#Procedure_to_populate_MMC.2FSD_Card was used to perform the IO operations. These results were obtained with a relatively new SD card with very few bad blocks, using SD cards of the same class with a considerable number of bad blocks will degrade the IO performance.

Connectivity Performance[edit]

These tests provide throughput comparison across commonly used transports/mediums.

Ethernet[edit]

Measures TCP Throughput between Server (running on Host PC) and Client (Android Platform) using different buffer sizes (bs in bytes) Both Server and client uses the Netperf utility. For more information about Netperf, please see Netperf Home page

ADB[edit]

Measure Android Debug Bridge (ADB) throughput between Host PC and Android device by pushing and pulling a 20MB file with random content 10 times. TX and RX numbers are from the Host PC point of view, so TX is measured by doing "adb push" on the Host PC.

MultiMedia Performance[edit]

Tests to measure video, audio, image and speech processing performance.

Video Display[edit]

To measure Video decode and display performance, the Big Buck Bunny clip was used. The clip has the following video and audio streams
Stream #0.0(und): Video: mpeg4, yuv420p, 352x288 [PAR 48:11 DAR 16:3], 30 tbr, 30 tbn, 30 tbc
Stream #0.1(und): Audio: aac, 48000 Hz, stereo, s16
DDR2 memory was set to 256M in the boot parameters (Default value)

For Android on DM37x EVM, which has multimedia DSP acceleration enabled, the sintel-1280-stereo.mp4 clip was used. The clip has the following video and audio streams. The ARM load (observed with 'top' command) is about 4~8% while playing the clip.
Video: AVC High@L3.1, CABAC, 5 ReFrames, 1,616 Kbps, 1280x544, 24.000 fps, yuv420p
Audio: AAC Ver4, LC, 192 Kbps, 2 channels, 48.0 KHz
