Rockchip RK3288 Specifications Released

Somebody working for a Chinese manufacturer informed me Rockchip RK3288 specifications have been released on We’ve already known the application processor was based on a quad core Cortex A17 processor with a Mali-T76X GPU, but this website provides some more details which appears to have been taken from RK3288 technical reference manual. I can’t confirm the source nor the accuracy of the data, but I doubt somebody would have just put up something with detailed fake information.

They mention RK3288 is an application processor destined to be used in high-end tablets, notebooks, all-in-one devices, smart monitors and TV Boxes, and that it features 4Kx2K support.. Let’s have a look at the details.

The CPU frequency has not been mentioned, but earlier reports indicate the four Cortex A17 core should be clocked at up to 1.8 GHz. The GPU is allegedly Mali-T760 or T-764, the latter does not exist yet, or has not announced yet. However, numbers previously leaked showing 300 MTri/s triangle rate and 2.4Gpix/s fill rate conflict with the 1390Mtri/s, and 11.2Gpix/s listed on ARM Mali-T760 page. My guess is that Mali-T764 does exist, but it has not been announced, and provides a lower cost and performance alternative to Mali-T760. There’s new “article” about Mali-T764 by Enybox, one manufacturer of TV box and HDMI TV sticks.

There are some nice features from the specifications like LPAE support for up to 8 GB RAM, Gigabit Ethernet support, HDMI 2.0 for True 4K2K up to 60 Hz, 4K2K decoding, but the lack of support for SATA and USB 3.0 is a little disappointing.

[…] competencia, en este caso se trata del nuevo SOC de Rockchip RK3288, gracias a los compañeros de cnx-software se nos da a conocer la web donde supuestamente se dan todos los detalles del […]


i hope tronsmart makes a tv box from this very soon


it looks a little fake to me, there is no mention to A17 cores and the website is no longer accessible, wait & see then


[…] The website states that Mali T760 GPU is to be found in the RK3288, but according to other reports, Rockchip RK3288 may also feature Mali T764 GPU which is yet unannounced but should provide very decent performance. ARM Cortex A17 Cortex A17 can be seen as an evolution from the Cortex A12. Cycle for cycle the Cortex-A17 processor offers over 60% performance uplift over the Cortex-A9 processor, the current leader in mid-range mobile market. This high performance is delivered while improving the efficiency – performance per milliwatt and per mm2. The Cortex-A17 processor is based on the popular 32bit ARMv7-A architecture, today’s most successful architecture in the mobile market. With over 1M apps supporting the ARMv7-A architecture, the Cortex-A17 processor is primed to bring the high-end performance levels of 2014 to next generation mid-range devices in 2015 delivering a better user experience at a reduced cost. The Cortex-A17 processor is scalable up to 4 cores, each containing a fully out-of-order pipeline delivering peak performance of today’s premium mobile devices. A fully integrated, low-latency L2 cache controller, accelerator interfaces to target specific use cases, and high-throughput AMBA®4 ACE Coherent Bus Interface enable the Cortex-A17 processor to be tailored for the right task. Its modern design is best complemented with the latest advanced IP like ARM Mali-T720 GPU, ARM Mali-DP500 DPU, and ARM Mali-V500 VPU and CoreLink™ CCI-400, but is also fully backwards compatible to existing AMBA3 and AMBA4 AXI based systems based on ARM Mali-450 GPU and CoreLink NIC-400 to ease integration and time-to-market.

Will be a very interesting chip, once mainline Linux Kernel supports it.


Mainline kernel ? Keep dreaming … Allwinner has a community around it and their SOCs are starting to work with mainline kernel buy Rockchip, they’ve got almost nothing as far as mainline goes. At least not that I know of.


I think information correctly, I am see same info in Ugoos Industrial blog, then asked Ugoos team. They confirmed what information is true and they started to research new android box based on this SoC


This SoC supports 4K2K, just I don’t know about frames. Begining to design Android TV Box soon 😉


[…] donc au tour du Rockchip RK3288, successeur du RK3188 en Cortex-A9, d’être dévoilé. CNX Software a publié la liste des capacités de […]


HDMI 2.0 to support maximum 4Kx2K display sounds great!


I thought the initial claim of the RK3288 being based on Cortex-A17 was wrong and in fact, it’s the Cortex-A12 (
The same about the GPU announcement, which was corrected in other articles, reporting about the new chip back in January, from a Mali-T76X to only be a Mali-T624.
Now I am confused.


cnxsoft, thanks for taking the time and clearing things up by providing that nice timeline. Much appreciated 🙂


[…] Rockchip RK3288 based devices should be available soon. At the end of last month, I read Pipo was about to introduce RK3288 Tablets at the Hong Kong electronics fair this month, and yesterday I’ve been informed some RK3288 mini PCs and TV Boxes had started to appear on Alibaba. […]


[…] it’s not listed in the specs. If it’s the case they probably use a USB to SATA chip, as RK3288 specs do not mention sata. The Wi-Fi module reads like AP6335. RK3288 is the small chip surrounded by a […]
