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)

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:

  • Wi-fi 802.11 a/b/g/n
  • Bluetooth 4
  • Contains FM receiver (unused, Si4709 instead)

See Anandtech coverage on Broadcam announcement.

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)?

True! It has a greater sub-pixel density than the Galaxy Nexus.

Sent from my GT-I9003 using XDA

Do you have a source for that statement? Because it sounds unlikely...

Quite to the countrary in fact...

Does anyone know if thus means there's an RGB notification light?
I've missed it since getting rid of nexus one :(

Any news on :

Which GPS chip and which modes (differential GPS/GLONAS)?

What type of flash memory hierarchy (how much of each type)?

Inquiring minds want to know.

Thanks. It's the same as in Galaxy Note then.

Let's hope the antenna is up to par!
