John the ripper was able to get some good results with a different FPGA: "Added FPGA support for 7 hash types for ZTEX 1.15y boards...Specifically, we support: bcrypt, descrypt (including its bigcrypt extension), sha512crypt & Drupal7, sha256crypt, md5crypt (including its Apache apr1 and AIX smd5 variations) & phpass. As far as we're aware, several of these are implemented on FPGAvfor the very first time. For bcrypt, our ~119k c/s at cost 5 in ~27W greatly outperforms latest high-end GPUs per board, per dollar, and per Watt." https://www.openwall.com/lists/announce/2019/05/14/1 https://www.openwall.com/lists/announce/2019/05/14/1
