Check side by side Rock64 (RK3328) and RockPro64 (RK3399) and search the internet for reviews/benchmarks.
Advances of RK3399:
Advances of RK3399:
- ~2x faster Cortex-A72 (architecture bigLITTLE for performance and power optimization, 3-way superscalar, 2x-4x more cache)
- ~2x throughput of memory (64-bit)
- ~2x-5x faster and newer GPU (Mali-T864 (wiki), OpenGL ES1.1/2.0/3.0/3.1, OpenCL, DX11, Vulkan...)
- more peripherals (PCIex, more video outputs, camera inputs and other peripherals ...)
I left this community in Aug 2019 due to PINE64 refusal to produce/deliver ROCK64-1G version 3 after more than one year of changing statuses to "planning", "evaluating", "releasing", "availability", "estimated availability" and finally "no schedule" . ROCK64 is dead platform without any advantage. Buy Raspberry PI 4 !
