Early Products
RK26xx series - Released 2006.RK27xx series - Rockchip was first known for their RK27xx series that was very efficient at MP3/MP4 decoding and was integrated in many low-cost personal media player products.
RK28xx series
The RK2806 was targeted at PMPs.
The RK2808A is an ARM926EJ-S derivative. Along with the ARM core a DSP coprocessor is included. The native clock speed is 560 MHz. ARM rates the performance of the ARM926EJ-S at 1.1 DMIPS/MHz the performance of the Rockchip 2808 when executing ARM instructions is therefore 660 DMIPS roughly 26% the speed of Apple's A4 processor. The DSP coprocessor can support the real-time decoding of 720p video files at bitrates of up to 2.5 Mbit/s. This chip was the core of many Android and Windows Mobile-based mobile internet devices.
The RK2816 was targeted at PMP devices, and MIDs. It has the same specifications as the RK2806 but also includes HDMI output, Android support, and up to 720p hardware video acceleration.

The Rockchip RK291x is a family of SoCs based on the ARM Cortex-A8 CPU core. They were presented for the first time at CES 2011. The RK292x are single core SoCs based on ARM Cortex-A9 and were first introduced in 2012.
The RK2918 was the first chip to decode Google WebM VP8 in hardware. It uses a dynamically configurable companion core to process various codecs. It encodes and decodes H.264 at 1080p, and can decode many standard video formats including Xvid, H.263, AVS, MPEG4, RV, and WMV. It includes a Vivante GC800 GPU that is compatible with OpenGL ES 2.0 and OpenVG. The RK2918 is compatible with Android Froyo , Gingerbread, HoneyComb and Ice Cream Sandwich. Unofficial support for Ubuntu and other Linux flavours exists. As of 2013, it was targeted at E-readers.
The RK2906 is basically a cost-reduced version of the RK2918, also targeted at E-readers as of 2013.
The Rockchip RK2926 and RK2928 feature a single core ARM Cortex A9 running at a speed up to 1.0 GHz. It replaces the Vivante GC800 GPU of the older RK291x series with an ARM Mali-400 GPU. As of 2013, the RK2926 was targeted at tablets, while the RK2928 was targeted at tablets and Android TV dongles and boxes.
The RK3066 is a high performance dual-core ARM Cortex-A9 mobile processor similar to the Samsung Exynos 4 Dual Core chip. In terms of performance, the RK3066 is between the Samsung Exynos 4210 and the Samsung Exynos 4212. As of 2013, it was targeted at tablets and Android TV dongles and boxes. It has been a popular choice for both tablets and other devices since 2012.
The RK3068 is a version of the RK3066 specifically targeted at Android TV dongles and boxes. Its package is much smaller than the RK3066.
The RK3028 is a low-cost dual-core ARM Cortex-A9-based processor clocked at 1.0 GHz with ARM Mali-400 GPU. It is pin-compatible with the RK2928. It is used in a few kids tablets and low-cost Android HDMI TV dongles.
The RK3026 is an updated ultra-low-end dual-core ARM Cortex-A9-based tablet processor clocked at 1.0 GHz with ARM Mali-400 MP2 GPU. Manufactured at 40 nm, it is pin-compatible with the RK2926. It features 1080p H.264 video encoding and 1080p decoding in multiple formats. Supporting Android 4.4, it has been adopted for low-end tablets in 2014.
The RK3036 is a low-cost dual-core ARM Cortex-A7-based processor released in Q4 2014 for smart set-top boxes with support for H.265 video decoding.
