I am looking for CPU, GPU and/or ASIC performance stats on hash performance. Specifically SHA256 and Argon2i. I've googled and only came up with very limited anecdotal evidence. Considering that this fast-changing field is so important for security managers, I would expect there to be a resource that provides the latest benchmarks in this area. Does such a thing exist?
In June 2016, Jeremi M. Gosney (the guy behind sagitta HPC) published the results obtained with their top-end password cracker, running Hashcat v3.00-beta: https://gist.github.com/epixoip/a83d38f412b4737e99bbef804a270c40
This list contains all hashing functions implemented by Hashcat which, unfortunately, doesn't support Argon2i yet.
Regarding SHA256, the results are:
Speed.Dev.#1.: 2865.2 MH/s (96.18ms) Speed.Dev.#2.: 2839.8 MH/s (96.65ms) Speed.Dev.#3.: 2879.5 MH/s (97.14ms) Speed.Dev.#4.: 2870.6 MH/s (96.32ms) Speed.Dev.#5.: 2894.2 MH/s (96.64ms) Speed.Dev.#6.: 2857.7 MH/s (96.78ms) Speed.Dev.#7.: 2899.3 MH/s (96.46ms) Speed.Dev.#8.: 2905.7 MH/s (96.26ms) Speed.Dev.#*.: 23012.1 MH/s
