On February Rockchip announced the RK3288 SoC, which combines four ARM Cortex-A17
cores with a 4- or 16-core Mali-T7xx GPU, a 4Kx2K video decoder, and
HDCP2.x security.
Rockchip is the second chipmaker to jump on ARM’s recently announced Cortex-A17 processor design, after MediaTek’s octa-core MT6595 system-on-chip. This heir to the quad-core, Cortex-A9 RK3188, which fuels Android stick computers like the Rikomagic MK802IV and Ugoos UM2, was tipped at CES as being a Cortex-A12 processor. However, Rockchip instead converted the SoC to the similarly 32-bit Cortex-A17.
Rockchip is aiming the RK3288 at high-end tablets, notebooks,
all-in-one devices, smart monitors, and “TV-Boxes.” With the help of the
SoC’s high-end video decoder, it’s especially suited for 4Kx2K TVs and
set-tops.
Rockchip did not list the clock rate of the RK3288, but the
Cortex-A17 is intended for 2GHz and above clock rates, according to ARM.
MediaTek clocks its MT6595 to 2.5GHz.
Each of the four Cortex-A17 cores have separate NEON and FPU coprocessors and 32KB/32KB cache allotments. The SoC also features a shared 1MB L2 Cache. The SoC offers virtualization extensions, as well as LPAE for up to 8GB address space, says Rockchip
The RK3288 is equipped with ARM’s new Mali-T7 series GPUs. It appears to support ARM’s recommended pairing of the new quad-core Mali-T720, as well as its much more powerful sibling, the Mali-T760 GPU. (MediaTek instead opted for a PowerVR Series6 GPU.)
The Mali-T760 offers 16 shader cores instead of four for the Mali-T720, and adds an advanced tiling unit. It’s said to offer four times the power efficiency of the earlier Mali-T604. On the RK3288, the GPU supports up to 3840 x 2160 display resolution and supports OpenVG1.1, OpenGL ES1.1/2.0/3.0, OpenCL1.1, RenderScript, and DirectX11.
The RK3288 also supplies a hardware video decoder, which supports 4Kx2K multi-format decoding. Video interfaces include HDMI 2.0, dual-channel LVDS and MIPI-DSI, and optional eDP1.1. Dual-channel MIPI-CSI2 camera support is available, along with support for up to 13- and 5-megapixel rear and front cameras, respectively.
The SoC provides extensive memory interfaces, including dual-channel, 64-bit DDR RAM, NAND flash, and eMMC. I/O is a standard mix of gigabit Ethernet, USB, and various serial interfaces. You also get GPS and Smart Card support.
The RK3288 is claimed to be the first SoC to provide for HDCP2.x secure boot, which supports Miracast and various DRM solutions. A cryptographic engine supports most standard protocols.
Specifications listed for the RK3288 include:

The Cortex-A17 was announced on February as a faster, smaller, and more power efficient heir to the Cortex-A9. The Cortex-A17 is also a big brother to the Cortex-A12 design announced last June,
and due to ship in SoCs later this year. The Cortex-A12 was also billed
as the successor to the Cortex-A9, with claims of 40 percent faster
performance in the same power envelope. Like all these processors, Linux
and Android are supported, along with other OSes.
