Allwinner H3 (sun8iw7p1) SoC features a Quad-Core Cortex-A7 ARM CPU, and a Mali400 MP2 GPU from ARM. The Allwinner H3 is a highly cost-efficient quad-core OTT box processor, primarily marketed as being for "home entertainment" systems.
It has a nearly-compatible variant known now, H2+.
It's rated to run at 1.296GHz, anything higher is overclocking (and usually overvolting). If you run it without heatsink, fan and proper dvfs settings, you risk overheating.
Currently, there is no sunxi support available yet. SDK has been released in May-2015, and devices are slowly becoming available.

H2+ is a variant of H3, targeted at low-end OTT boxes, which lacks Gigabit MAC and 4K HDMI output support.
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).

U-Boot supports these H3 boards via defconfigs:
* NanoPi Neo (since v2016.11) * Orange Pi 2 (since v2016.05) * Orange Pi Lite (since v2016.09) * Orange Pi One (since v2016.05) * Orange Pi PC (since v2016.01) * Orange Pi PC Plus (since v2016.09) * Orange Pi Plus (since v2016.01) * Orange Pi Plus 2E (since v2016.09)
Official U-Boot support still missing for these H3 boards:
* Banana Pi M2+ (as a workaround, please use orangepi_plus defconfig) * NanoPi M1 (as a workaround, please use orangepi_one defconfig) * NanoPi Neo Air (as a workaround, a patch to a board configuration is provided on the device page) * Orange Pi Mini 2 (as a workaround, please use orangepi_2 defconfig) * Orange Pi Plus 2 (as a workaround, please use orangepi_plus defconfig) * pcDuino4 Nano (as a workaround, please use orangepi_one defconfig)
Several H3 boards are also supported by the mainline kernel, but not all features are yet available in the mainline.
The kernel supports these H3 boards via defconfigs:
* Banana Pi M2+ * NanoPi Neo * Orange Pi 2 * Orange Pi Lite * Orange Pi One * Orange Pi PC * Orange Pi PC Plus * Orange Pi Plus * Orange Pi Plus 2E
The kernel support still missing for these H3 boards:
* NanoPi M1 (as a workaround, please use sun8i-h3-orangepi-one.dtb) * NanoPi Neo Air * Orange Pi Mini 2 (as a workaround, please use sun8i-h3-orangepi-2.dtb) * Orange Pi Plus 2 (as a workaround, please use sun8i-h3-orangepi-plus.dtb) * pcDuino4 Nano (as a workaround, please use sun8i-h3-orangepi-one.dtb)
Features with work-in-progress implementations coming in the future kernels (4.9 and later) include:
* Audio codec * Crypto * CSI * Display (drm) * EMAC * HW spinlocks * I2C (4.9) * NAND flash * PWM (4.9) * Touch / Thermal / GPADC * USB OTG
