Rikomagic MK902II sporting the new RK3288 SOC

Rikomagic is prepping an Android 4.4 ready “MK902II” mini-PC claimed to be three times faster than earlier models thanks to its Cortex-A17 Rockchip RK3288.

Rikomagic’s MK902II is set to arrive in June, only a few months after the company launched its first mini-PC versions of the previously HDMI stick form-factor media players. The Android 4.4-focused MK902II has the same footprint as the recent MK902 and very similar, Ubuntu Linux-based MK902 LE. Rikomagic has yet to announce a Linux version of the MK902II, although like the MK902, the MK902II can run Linux as well.

Like the previous models, the MK902II is designed primarily for plugging into a TV. However you can also use it as a mini desktop PC, signage computer, or other media-savvy embedded device.

The new system runs three times faster than the MK902, claims Rikomagic, thanks to moving from Rockchip’s quad-core, Cortex-A9 based RK3188 system-on-chip to the new quad-core RK3288. Along with the octa-core MediaTek MT6595, the RK3288 is the first SoC to showcase ARM’s new Cortex-A17 design. The Rockchip RK3288 will also soon be available in a media-focused Ugoos UT3 mini-PC.

The Cortex-A17 design is billed as a faster, smaller, and more power efficient heir to the Cortex-A9, and it also appears to edge into Cortex-A15 territory. The RK3288′s four Cortex-A17 cores are clocked at up to 1.8GHz, and are accompanied with separate NEON and FPU coprocessors and 32KB/32KB cache allotments. The SoC also features a shared 1MB L2 Cache, virtualization extensions, as well as LPAE for up to 8GB address space, says Rockchip.

The RK3288 is paired here with ARM’s powerhouse new Mali-T760 GPU, which boasts 16 shader cores instead of four for its less powerful sibling, the Mali-T720. It’s also four times as power efficient as of the earlier Mali-T604. 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 adds to the multimedia fun with a separate hardware video decoder, which supports 4Kx2K multi-format decoding.

Other than the new processor, the MK902II appears to be almost identical to the MK902, with 2GB RAM, 8GB or 16GB flash, and microSD expansion. The main difference is that the Ethernet port advances to a gigabit connection, and one of the four USB ports has gone from host to client.
WiFi and Bluetooth 4.0 are standard, along with HDMI, AV out, and S/PDIF audio connections. Once again, a camera and mic are available, but it’s unclear if it’s the same 5-megapixel camera.
