This analysis is done based on elements from a live system, without physical tear-down.
Thanks to Brian Klug for the help with running a modified version of my reporting tool to get this data.
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:
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/)
