RK32xx series
Rockchip has announced the RK3288 for production in the second quarter of 2014. Recent information suggests that the chip uses a quad-core ARM Cortex-A17 CPU, although technically ARM Cortex-A12, which as of October 1, 2014, ARM has decided to also refer to as Cortex-A17 because the latest production version of Cortex-A12 performs at a similar performance level as Cortex-A17.

Inconsistent information about CPU cores used in RK3288
Early reports including Rockchip first suggested in summer 2013 that the RK3288 was originally designed using a quad-core ARM Cortex-A12 configuration. Rockchip's primary foundry partner GlobalFoundries announced a partnership with ARM to optimize the ARM Cortex-A12 for their 28 nm-SLP process.  This is the same process used for earlier Rockchip chips such as the RK3188, and matches the choice of Cortex-A12 cores in the design of the RK3288.

In January 2014, official marketing materials listed the CPU cores as ARM Cortex-A17. At the CES electronics show in January 2014, someone apparently corrected the CPU specification as being ARM Cortex-A12 instead of Cortex-A17 on one of the panels of their show booth. However, since then, official specifications from Rockchip's website and marketing materials as well specifications used by device manufacturers have continued to describe the CPU as a quad-core ARM Cortex-A17.

Recent testing of early RK3288-based TV boxes (August/September 2014) provided evidence that the RK3288 technically contains Cortex-A12 cores, since the "ARM 0xc0d" CPU architecture reported by CPU-Z for Android is the reference for Cortex-A12, while the original Cortex-A17 is referred to as "ARM 0xc0e".

However, on the ARM community website, ARM clarified the situation on October 1, 2014, saying that Cortex-A12, for which Rockchip is one of the few known customers, will be called Cortex-A17 from now on, and that all references to Cortex-A12 have been removed from ARM's website. ARM explained that the latest production revision of Cortex-A12 now performs close to the level of Cortex-A17 because the improvements of the Cortex-A17 now also have been applied to the latest version of Cortex-A12. In this way, Rockchip now gets the official blessing from ARM for listing the cores inside the RK3288 as Cortex-A17.

The first Android TV stick based on RK3288 was launched in November 2014 ("ZERO Devices Z5C Thinko").

Markets and competition

In the market for SoCs for tablets, Rockchip faces competition with Allwinner Technology, MediaTek, Intel, Actions Semiconductor, Spreadtrum, Leadcore Technology, Samsung Semiconductor, Qualcomm, Broadcom, VIA Technologies, UNISOC and Amlogic.

After establishing a position early in the developing Chinese tablet SoC market, in 2012 it faced a challenge by Allwinner. In 2012, Rockchip shipped 10.5 million tablet processors, compared to 27.5 million for Allwinner.
However, for Q3 2013, Rockchip was forecast to ship 6 million tablet-use application processors in China, compared to 7 million for Allwinner who mainly shipped single-core products.
Rockchip was reported to be the number one supplier of tablet-use application processors in China in Q4 2013, Q1 2014 and Q2 2014.

Chinese SoC suppliers that do not have cellular baseband technology are at a disadvantage compared to companies such as MediaTek that also supply the smartphone market as white-box tablet makers increasingly add phone or cellular data functionality to their products.

Intel Corporation made investments into the tablet processor market, and was heavily subsidizing its entry into the low-cost tablet market as of 2014.

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. 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. Both Intel and Rockchip will sell the new part to OEMs and ODMs, primarily into each company's existing customer base.

As of October 2014, Rockchip was already offering Intel's XMM 6321, for low-end smartphones. 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. Rockchip has not earlier targeted the smartphone space in a material way.
