Rockchip Introduces Three Tablet SoCs: RK3126C, RK3326, RK3366, and RK3368H Processor for 2-in-1 Laptops

Rockchip has launched four more processors at the Hong Kong Electronics Fair 2017, with three SoCs specifically targeting tablets namely RK3126C, RK3326 and RK3366, and one SoC, RK3368H modified from RK3368, designed to provide a lower cost alternative to RK3288 and RK3399 for 2-in-1 hybrid laptops and tablets.

The company only provided limited information with regards to the tablet SoCs specifications:

  • RK3126C quad core processor supporting 1080p video decoding and HD (720p?) displays for entry-level tablets
  • RK3326 quad core ARM Cortex A35 processor with a quad core Mali GPU, DDR3/LPDDR memory interface, 1080p60 H.264, MPEG-4/-2 video decoding, and 1080p30 H.264 video encoding
  • RK3366 quad core ARM Cortex A53 processor with a quad core Mali GPU, DDR3/LPDDR memory interface, USB 3.0 interface, and 4K H.265 video decoding

All three processors will be running Android 7.1. I could not find any tablets based on the processor yet, so we may have to wait a few more month.

We have more details about RK3368H processor since it’s an update of RK3368 processor, and a tablet was showcased at the event.

Rockchip RK3368H key specifications:

  • CPU – Octa-core ARM Cortex A53 processor @ 1.5 Ghz
  • GPU – Imagination PowerVR SDX6110 GPU @ 600 MHz
  • Memory I/F – 32-bit DDR/LPDDR
  • Display I/F  – Full HD Display supported
  • Video – 4K H.265 and H.264 video decoding
  • Ethernet and HDMI port “reduced” (likely meaning removed) for lower costs
  • 28nm process

The processor can run Android 7.1 operating systems, including desktop optimized version such as Remix OS, Phoenix OS, or Light Biz OS. The company claims the tablet shown above gets around 48,000 points in Antutu benchmark. Netbook Italia also posted a video of the tablet (in Italian) showing it’s made by Chiptrip, but they have not updated their MID page with the new tablet just yet.

Well, all they’ve disclosed about RK3126C is that it is a cheap quad core and probably does not have 64-bit CPUs. Surely wouldn’t be Cortex A5 or A7 so, maybe the Cortex A32 is about to hit the street

I wonder if they improved the DDR3 controller on the 3368H – the original in the 3368 is not exactly a class leader.

@Curmudgeon
it is after all budget soc, based on their naming scheme, it is probably RK3126(Cortex-A7) with some customization, like how allwinner H3 & H2.
its cheaper that way to, since cortex A-32 = new license fee.(i assume)

GPU • Mali-400MP2 GPU, support OpenGL ES1.1/2.0
• High performance dedicated 2D processor
Multi-Media • Multi-format 1080P 60fps video decoders (H.265, H.264,VC-1, MPEG-1/2/4, VP8)
• 1080P video encoding for H.264,VP8
Display • Support RGB/LVDS/MIPI-DSI, resolution up to 1280*720
Memory • 16bits DDR3-1066/DDR3L-1066
• Support MLC NAND, eMMC 4.51, Serial Nor FLASH
Connectivity • Dual DVP Sensor interface , up to 5M Pixels
• Integrated Audio Codec,Ethernet MAC, SDIO3.0, USB2.0 OTG/HOST,I2C,UART,SPI, I2S,S/PDIF

it seems the RK3366 features the mali T764 according to its DTSI file
https://github.com/rockchip-linux/kernel/blob/release-4.4/arch/arm64/boot/dts/rockchip/rk3366.dtsi#L1682

i wonder how ‘cost-effective’ translates in $

it would be nice to have a look at its datasheet too
