RK3399 Based TV Box - 4GB / 64GB (OC + FAN)

[ataa]

• OC (1.8/2.088) within recommended voltages.
• 50mm Heatsink + 50mm 5v Fan, High Quality Thermal Compound. (Fan Power Usage: 0.93W)
• 5v 4A, High Quality power supply. (3.36W idle, 10.54w on 100%, including fan power usage of 0.93W)
• LPDDR3 running @ 800Mhz, (DRAM chip is 2133Mhz Samsung LPDDR3 but Processor can support up to 933Mhz, I need to build u-boot to reach that frequency, I've not managed to build one yet)
• Headless server (unnecessary kernel modules and hardware removed).
• Boot from EMMC
• Armbian 20.11 Focal with Linux 5.9.9-arm-64

3200 / 1.553 = 2060 Mbps for AES-256-CBC 3200 / 1.504 = 2127 Mbps for AES-128-CBC?!

Edit: Found this in RK3399 Datasheet:

Embedded dual-channel encryption and decryption engine  Support AES 128/192/256 bits key mode, ECB/CBC/CTR/XTS chain mode, Slave/FIFO mode  Support DES/3DES (ECB and CBC chain mode), 3DES (EDE/EEE key mode), Slave/FIFO mode  Support SHA1/SHA256/MD5(with hardware padding) HASH function, FIFO mode only  Support 160-bit Pseudo Random Number Generator (PRNG)  Support 256-bit True Random Number Generator (TRNG)  Support PKA 512/1024/2048 bit Exp Modulator
