Rockchip SoCs Comparison Table, RK32xx Quad Core Cortex A12 Coming Up in 2014

Orange Pi Development Boards

They guys at Linux Rockchip have setup a comparison table between Rockchip processors, but it’s not quite complete yet, and Rockchip noticed it, so they’ve just sent them the most recent Company Presentation that provides more details, including a roadmap.

In this documentation, we can see the company targets different types of products with their SoCs:

  • Android OTT dongle/box (aka mini PC, HDMI TV dongles…) – RK2928, RK3066, RK3068, and RK3188
  • Tablets – RK2926, RK2928, RK3028, RK3066, RK3168, and RK3188
  • EPD E-Book – RK2818, RK2906 and RK2918
  • MP3 player – RKnanoC

On page 12 of the presentation, they have a convenient comparison table for the SoC used in mini PCs and Tablets.

We also learn Rockchip is working on a new RK32xx SoC (RK3288?) that will become available in Q2 2014 (Engineering Samples) with four of the latest ARM Cortex 12 cores, and the following features:

  • Rockchip_RK32xx_Block_Diagram28nm HKMG Process
  • 1.8GHz Quad ARM A12 core
  • ARM Mali-T624 GPU, support OPENGL ES1.1/2.0/Halti, OPEN VG1.1, OPENCL, Directx11
  • High performance dedicated 2D processor
  • Dual channels DDR controller, support, DDR3, DDR3L, LPDDR2, LPDDR3
  • Display resolution up to 3840X2160, MIPI, LVDS, HDMI transmitter
  • Embed 1300M ISP and MIPI-CSI interface
  • 4K video multi format video decoding
  • 1080P video encoding for H.264 and VP8, MVC
  • Support MLC NAND, eMMC
  • Image enhancement HW
  • Low power display improvement HW
  • Rich peripheral and connectivity

Interestingly, there’s no hardware support for H.265/HEVC and VP9 even in this 2014 processor, so they’ll have to decode these codecs by software, just like they plan to do with RK3188 up to 1080p.

Other interesting bits (to me) include:

  • RK3168 and RK3188 are pin-to-pin compatible
  • RK3068 has more pins than RK3066, yet it’s much smaller thanks to a smaller pitch (BGA548 14X14 0.5mm pitch vs BGA453 19X19, 0.8mm pitch)
  • RK292X allows for low cost TV-BOX solution (“wireless HDMI”) with a PCBA cost of about $10 US.

I wondered:
– why the RK3188 can be clocked faster than the RK3168, when they both use the same process. (& presumably 4 cores means more heat…)
– what kind of performance improvements over the RK3188 might come from shifting to ARM Cortex 12?

>why the RK3188 can be clocked faster than the RK3168
quality control/binning ? RK3168 are bad RK3188 ? (Intel does that)
power consumption ?

Cortex 12 has interesting stuff, like GPGPU and virtualization. and more RAM. So nice little servers. Remember that AllWinner Eva said one time to charbax that AW was working on a “server” CPU. I am sure Rockchip is preparing themselves too. Plus it looks “better” that A7 :), since it A12. So better than AW and MTK !

Atleast no Mali-400 anymore 🙂

I wonder will they still use the CedarX video codec with their otherwise ARM’s techs (Cortex-A12 + Mali-T624)?

Sure the ARM Mali-V500 also lacks h.265, but at least that way it would become “all in-house ARM” based SoC.

Not really sure why people are calling the V500 a DRM nightmare, as ALL hardcoded video codec blocks are equally DRM-ridden. People are just bummed out that they still do not get a DRM-free video acceleration? Unfortunately that will never happen by using MPEG-LA standards.

Just a small correction: They say Q2 2014 for RK32xx not Q4. 🙂

So Rockchip will continue to be a year (or more) behind. Snapdragon 800 is about to be released. I expect Rockchip won’t be matching it’s performance for at least two more years.

CedarX is only used by Allwinner SoCs, not by Rockchip.

Rockchip uses Stagefright API (libstagefright) on Android.

And I do not think Rockchip officially supports Linux.

@Rocker
Whoops, my Allwinner past creeps up on me. 😉

Anywho, I have always thought that the stagefright is nothing but an API interface to the hardware itself, so the actual hardware block is something else, have not yet looked up libstagefright code does it actually do “all” work with direct access to the VPU, or is it just an common API to some (interchangeable) binary blob that interfaces to the VPU.
