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 (PMP) 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.^{[citation needed]}

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 RK2918^[27] 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 (2.2), Gingerbread (2.3), HoneyComb (3.x) and Ice Cream Sandwich (4.0).^[28] Unofficial support for Ubuntu and other Linux flavours exists. As of 2013, it was targeted at E-readers.^[29]

The RK2906 is basically a cost-reduced version of the RK2918, also targeted at E-readers as of 2013.^[29]

The Rockchip RK2926 and RK2928^[30] 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.^[29]

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.^{[31][32][33][34][35]} As of 2013, it was targeted at tablets and Android TV dongles and boxes.^[29] It has been a popular choice for both tablets and other devices since 2012.

Cooperation with Intel

In May 2014, Intel announced an agreement with Rockchip to jointly deliver an Intel-branded mobile SoC platform based on Intel's Atom processor and 3G modem technology.^[3] Under the terms of the agreement, the two companies will deliver an Intel-branded mobile SoC platform. The quad-core platform will be based on an Intel Atom processor core integrated with Intel's 3G modem technology, and is expected to be available in the first half of 2015.^[3] Both Intel and Rockchip will sell the new part to OEMs and ODMs, primarily into each company's existing customer base.^[3]

As of October 2014, Rockchip was already offering Intel's XMM 6321, for low-end smartphones.^[81] It has two chips: a dual-core application processor (either with Intel processor cores or ARM Cortex-A5 cores) with integrated modem (XG632) and an integrated RF chip (AG620) that originates from the cellular chip division of Infineon Technologies (which Intel acquired some time ago). The application processor may also originate from Infineon or Intel.
