Default GT-I9300 Fully Detailed Analysis

Inside Galaxy S III GT-I9300

SoC


Exynos 4 smdk4x12

CPU:

4 cores.
features: swp half thumb fastmult vfp edsp neon vfpv3 tls

Linux Frequency scaling:


Max Frequency 1.4 GHz
1.3 GHz
1.2 GHz
1.1 GHz
1 GHz
900 Mhz
800 Mhz
700 Mhz
600 MHz
500 Mhz
Min frequency: 200 Mhz

Scaling driver: exynos_cpufreq,
Active governor: pegasusq
Cpu frequency transition latency: 100000 ns
Exynos bus frequency: 160160

Audio codec:

Wolfson Micro WM1811
http://www.wolfsonmicro.com/products/audio_hubs/WM1811/
100dB SNR Class W Headphone amp output, ReTune DSP, 3x digital interface.
Ultra low power standby, flexible, multi-button accessory detect.

Like WM8994 in Galaxy S / Nexus S, except:
  • 1x stereo DAC instead of 2x.
  • 2x 2W Speaker amp instead of 2x 1W
Smaller and probably cheaper, same sound quality expected.

Audio driver configuration & policy implementation based on TinyUCM (/etc/tinyucm.conf)
Probable subset of TinyHAL implementing codec configuration in config files instead of having everything hardcoded in ROM or kernel driver at compile time.

Native sampling rate: 44100 Hz. It means music played will be sent as-is to the DAC instead of being processed by a software up-sampling routine as it is on Galaxy Nexus or other devices with codecs accepting only 48000 Hz.

Confirmed Voodoo Sound capable

FM Radio:

Si4709 receiver, as in Galaxy S / Galaxy S II / Galaxy Note

Display:

Super AMOLED HD, Pentile matrix, 4.8”
Likely generation as Galaxy Nexus and Galaxy Note display.

Resolution: 720x1280
Refresh rate: 60Hz
Default color mode: 32bit.
Real DPI as calculated by driver (need confirmation by measurements)
  • 305dpi, physical width 60mm, physical height 106mm

MHL output controller: Samsung sii9234 (need confirmation about who really manufactures the chip, and if its Sil9234. Driver say Sii9234, might be a typo in driver?)

mDNIe hardware support (mode, scenarios, outdoor)

OpenGL / EGL:

Renderer name: Mali-400 MP

  • EGL_KHR_gl_texture_cubemap_image
  • EGL_KHR_gl_renderbuffer_image
  • EGL_KHR_fence_sync
  • EGL_ANDROID_image_native_buffer

Camera:

Back: Samsung LSI S5C73M3 8M pixel camera
http://patchwork.linuxtv.org/patch/10708/ reading shows the sensor should support 120fps capture at 640x480. Might be a potential camera hack!

Network:

Broadcom BCM4334 - latest ultra low power solution for smartphones
  • Wi-fi 802.11 a/b/g/n
  • Bluetooth 4
  • Contains FM receiver (unused, Si4709 instead)

See Anandtech coverage on Broadcam announcement.

Radio:


Baseband: XMM6262 (thanks Brian Klug, good catch!)

ROM details:


Android 4.0.4
London demo device ROM version: I9300XXALE4a (build date Thu May 3 16:05:51 KST 2012)
Built for CPU armeabi-v7a
ro.build.product=m0 << strange
Android UI LCD density configured to 320 dpi
100Hz maximum input frequency (touch)

Voice recognition server named WakeUpCmdRecognizer, based on acoustic and grammar models (/system/wakeupdata/sensory/)

Misc

Brilliant, thanks!

Now if we only knew what type of flash memory is used for each partition and what are the real-life r/w speeds for each?

Is it all based on same flash-memory type, or will we get the same kind of "out of oneNAND flash memory" fiascos we got with the original Galaxy S ?

Further, I wonder if anybody has info on the GPS chip? Samsung's own or SiRF Star? Is it simultaneous dual-mode GPS for both satellite networks (offering differential GLONASS + GPS for better accuracy)?

Any news on the following:

1. GPS Chip mfg/model?

2. Flash memory types / sizes / OS hierarchy (ONEnand, NAND, etc)?

I think the display could be a later version than in the Nexus because red appears to have smaller LED's. But it's hard to tell. Could be down to the camera.
