Rockchip RK3288 processor shows up online



While we already knew a lot of details for the Rockchip RK3288 processor, some website probably set up by Rockchip now reveals a lot more information. Rockchip RK3288 SoC is the first SoC to be based on a quad core Cortex A17 processor with a Mali-T76X GPU and should arrive as late as 2015. Rockchip also advertises it as the first SoC with real 4Kx2K video decoder. While we can not verify the source, it doesn’t look like somebody will set up a whole website with fake data.

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.
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.
