We're finally in deep enough to see some differences between these two—some hardware components are the same as in the HDMI version, although we spy a couple Audio-specific ICs as well:

Marvell Avastar 88W8887 VHT WLAN, Bluetooth, NFC and FM Receiver

Nanya NT5CC128M16IP-DI/EK DDR3L 2 Gb SDRAM

AKM AK4430 192kHz 24-Bit Stereo DAC

On the reverse:

Marvell Armada 88DE3006 1500 Mini Plus dual-core ARM Cortex-A7 media processor

Toshiba TC58NVG1S3HBAI6 2 Gb NAND Flash Memory

Texas Instruments DRV632 DirectPath 2-VRMS pop-free stereo line driver
