Introduction

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

This is a collection of benchmarks comparing mainly CPU speed and other data transfer operations. In below tests, AM389x@1GHz, and AM387x@800MHz.

RowboPerf: ARM

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.

Dhrystone	948.59 DMIPS	569.15 DMIPS
Whetstone	250 MIPS	166.7 MIPS
Linpack	24524 Kflops	14610 Kflops

Boot Time

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)	AM389x	AM387x
SD First Boot Time1	60	66.2
SD Boot Time	23	27.9

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

Particules(fps)	AM389x	AM387x
fps	24.3 to 26.8	16.7 to 18.3

File Storage Performance

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.

1 The performance numbers for AM389x reported by the StorageIO application are not considered to be accurate and the root cause is being investigated.

Connectivity Performance

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

Ethernet

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

TCP Throughput	AM389x	AM387x
bs=16	136.22 Mb/s	106.6 Mb/s
bs=1024	136.49 Mb/s	101.69 Mb/s
bs=4096	263.99 Mb/s	233.56 Mb/s
bs=8192	373.67 Mb/s	233.56 Mb/s

ADB

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.
