Based on Rockchip RK3399

CPU Architecture

big.LITTLE architecture: Dual Cortex-A72 + Quad Cortex-A53, 64-bit CPU

• Full implementation of the ARM architecture v8-A instruction set (both AArch64 and AArch32)
• ARM Neon Advanced SIMD (single instruction, multiple data) support for accelerated media and signal processing computation
• ARMv8 Cryptography Extensions
• VFPv4 floating point unit supporting single and double-precision operations
• Hardware virtualization support
• TrustZone technology support
• Full CoreSight debug solution
• One isolated voltage domain to support DVFS

Cortex-A72 (big cluster):

• Dual-core Cortex-A72 up to 2.0GHz CPU
• Superscalar, variable-length, out-of-order pipeline
• L1 cache 48KB Icache and 32KB Dcache for each A72
• L2 cache 1024KB for big cluster

Cortex-A53 (little cluster):

• Quad-core Cortex-A53 up to 1.5GHz CPU
• In-order pipeline with symmetric dual-issue of most instructions
• L1 cache 32KB Icache and 32KB Dcache for each A53
• L2 cache 512KB for little cluster

Cortex-M0 (control processors):

• Cortex-M0 CPU
• Two Cortex-M0 cooperate with the central processors
• Architecture: Armv6-M
• Thumb/Thumb2 instruction set
• 32 bit only

GPU Architecture

• ARM Mali-T860MP4 Quad-core GPU
• The highest performance GPUs built on Arm Mali’s famous Midgard architecture, the Mali-T860 GPU is designed for complex graphics use cases and provide stunning visuals for UHD content.
• Frequency 650MHz
• Throughput 1300Mtri/s, 10.4Gpix/s

Graphic interface standards:

• OpenGL® ES 1.1, 1.2, 2.0, 3.0, 3.1, 3.2. (Panfrost has initial support of 3.0 beginning 2020/02/27)
• Vulkan 1.0, using the Mali binary blob. (Panfrost does not support Vulkan as of 2020/06/24)
• OpenCL™ 1.1, 1.2
• DirectX® 11 FL11_1
• RenderScript™

System Memory

RAM Memory:

• LPDDR4
• 800MHz, (limited by RK3399)
• Dual memory channels on the CPU, each 32 bits wide
• Quad memory channels on the RAM chip, each 16 bits wide, 2 bonded together for each CPU channel
• 4GB as a single 366 pin mobile RAM chip

Storage Memory:

• 64GB eMMC module, can be upgraded to an 128GB eMMC module. (The initial PINE64 community build version shipped with a 128GB eMMC.)
• eMMC version 5.1, HS400, 8 bit on RK3399 side
• Bootable

SPI flash:

• SPI
• 128Mbit / 16MByte
• 1 bit interface
• Bootable, (first boot device, ahead of eMMC & SD card)
• U-Boot images can be made to work, but as of 2020/06/24 there is no standardized image available.

Video out

• USB-C Alt mode DP
• Up to 3840x2160 p60, dependant on adapter, (2 lanes verses 4 lanes)

Expansion Ports

MicroSD card:

• Bootable
• Supports SD, SDHC and SDXC cards, up to 512GB tested. SDXC standard says 2TB is the maximum.
• Version SD3.0, (MMC 4.5), up to 50MB/s
• SD card Application Performance Class 1 (A1), (or better), recommended by some users, for better IOPS

USB ports:

• 1 x USB 2.0 Type-A Host Port, bootable
• 1 x USB 3.0 Type-A Host Port, 5Gbps, is not bootable
• 1 x USB 3.0 Type-C OTG Port, 5Gbps, (includes laptop charging function), is not bootable
• Note that high power USB devices may not work reliably on a PBP. Or they may draw enough power to drain the battery even when the PBP is plugged into A.C. One alternative is externally powered USB devices.
