 * 32 KB (Instruction) / 32KiB (Data) L1-Cache per core
 * SIMD NEON, VFP4
 * Virtualization
 * Large Physical Address Extensions (LPAE) 1TB

GPU

 * ARM Mali400 MP2 600 Mhz
 * Featuring 1 vertex shader (GP) and 2 fragment shaders (PP).
 * Complies with OpenGL ES 2.0

Memory

 * DDR2/DDR2L-DDR3/DDR3L controller
 * NAND Flash controller and 64-bit ECC

Video
3840×1080,1920x2160 3D decoding
 * Ultra HD 4k and Full HD 1080p video decoding of MPEG-2, MPEG-4 SP/ASP GMC, H.263, H.264, H.265, WMV9/VC-1, and VP8
 * BD Directory, BD ISO and BD m2ts video decoding
 * H.264 High Profile 1080P@30fps encoding
 * Complies with RTSP, HTTP,HLS,RTMP,MMS streaming media protocol
 * Video Engine/ Cedar Engine?

Display

 * Integrated HDMI V1.4 with HDCP1.2 4K@30fps
 * TV CVBS output

Camera

 * Integrated parallel 8-bit I/F YUV422 sensor
 * Support CCIR656 protocol fot NTSC and PAL
 * 5M CMOS sensor support
 * Support video capture resolution up to 1080p@30fps

Audio

 * Two audio digital-to-analog(DAC) channels 92dB SNR
 * Two differential microphone inputs (one low-noise)
 * Stereo Linein input

Embedded Controller

 * AR100, an OpenRISC 1000 32-bit controller. Manages deep powersave modes and has closed Allwinner's BSP. Supports ORBIS32 base instructios set
 * It seems to be tightly integrated with "RTC block"

Miscellaneous

 * Thermal Sensor Controller (TSC) providing over-temperature protection interrupt and over-temperature alarm interrupt (but it's still has issues with overheating to 90°С so be careful)
 * no PMU (its role is partially done by AR100 coprocessor)
 * package: FBGA347, 14 mm x 14 mm, 0.65 mm Pitch

H2+ and H3

 * H2+ is a variant of H3, targeted at low-end OTT boxes, which lacks Gigabit MAC and 4K HDMI output support. So, H2+ is cost-down version of already cheap H3


 * H3 images are proven to run on H2+.


 * According to the source code of BSP, variants differ by the last byte of the first word of SID. 0x42 and 0x83 indicates H2+, 0x00 and 0x81 indicates H3, and 0x58 indicates H3D (a still unknown variant).
