LPDDR4 Benchmarks

On the bionic-containers-rockpro64-0.6.44-239-arm64 image for the ROCKPro64, I got this:

Code:

rock64@rockpro64:~$ cryptsetup benchmark # Tests are approximate using memory only (no storage IO). PBKDF2-sha1       774428 iterations per second for 256-bit key PBKDF2-sha256    1470653 iterations per second for 256-bit key PBKDF2-sha512     489988 iterations per second for 256-bit key PBKDF2-ripemd160  378274 iterations per second for 256-bit key PBKDF2-whirlpool  172010 iterations per second for 256-bit key argon2i       4 iterations, 386620 memory, 4 parallel threads (CPUs) for 256-bit key (requested 2000 ms time) argon2id      4 iterations, 369429 memory, 4 parallel threads (CPUs) for 256-bit key (requested 2000 ms time) #     Algorithm | Key |  Encryption |  Decryption        aes-cbc   128b   616.2 MiB/s   832.0 MiB/s    serpent-cbc   128b           N/A           N/A    twofish-cbc   128b    80.4 MiB/s    82.4 MiB/s        aes-cbc   256b   529.3 MiB/s   747.7 MiB/s    serpent-cbc   256b           N/A           N/A    twofish-cbc   256b    80.6 MiB/s    82.1 MiB/s        aes-xts   256b   681.4 MiB/s   680.5 MiB/s    serpent-xts   256b           N/A           N/A    twofish-xts   256b           N/A           N/A        aes-xts   512b   620.1 MiB/s   619.6 MiB/s    serpent-xts   512b           N/A           N/A    twofish-xts   512b           N/A           N/A

And just for comparison, here is the same benchmark on the rock64 (same image, but rock64 version):

Code:

rock64@rock64:~$ cryptsetup benchmark # Tests are approximate using memory only (no storage IO). PBKDF2-sha1 277989 iterations per second for 256-bit key PBKDF2-sha256 495546 iterations per second for 256-bit key PBKDF2-sha512 202584 iterations per second for 256-bit key PBKDF2-ripemd160 160824 iterations per second for 256-bit key PBKDF2-whirlpool 71157 iterations per second for 256-bit key argon2i 4 iterations, 284387 memory, 4 parallel threads (CPUs) for 256-bit key (requested 2000 ms time) argon2id 4 iterations, 299706 memory, 4 parallel threads (CPUs) for 256-bit key (requested 2000 ms time) # Algorithm | Key | Encryption | Decryption aes-cbc 128b 348.7 MiB/s 433.2 MiB/s serpent-cbc 128b N/A N/A twofish-cbc 128b 29.7 MiB/s 30.6 MiB/s aes-cbc 256b 300.6 MiB/s 394.8 MiB/s serpent-cbc 256b N/A N/A twofish-cbc 256b 29.9 MiB/s 30.7 MiB/s aes-xts 256b 385.2 MiB/s 385.6 MiB/s serpent-xts 256b N/A N/A twofish-xts 256b N/A N/A aes-xts 512b 356.9 MiB/s 356.1 MiB/s serpent-xts 512b N/A N/A twofish-xts 512b N/A N/A
