If anyone has any insight on this, been reading/searching for some time and cannot figure it out:

Have a single rig with 4x1050 TI and 1xRX 560 (yes, I'm small time - but sorry, already taken, ladies). Running v11.4 as 11.5 keeps locking the PC up completely. AMD drivers are 17.12.1. Mining in ETH only mode. Zero hardware errors on HWInfo and no BIOS/clock/voltage/power modifications on the AMD.

The AMD card is showing a hashrate of ~9.18 vs ~13.5 on all the Nvidia cards. Miner showing 0 rejected/incorrect shares after 24 hours of mining. AMD card has right at 50% of the average shares of the 4 Nvidias - on nanopool if that matters. Looking at the submissions from the logs and all the shares from the Nvidia cards are accepted within ~170ms, but the AMD are ~2200ms?

Trying to understand the variance on the AMD - if I go by the hash rate vs the Nvidias, it should be closer to 68% not 50%, and what is the deal with the shares taking so long to be accepted from this one card? Thanks

@dropky - would appreciate any progress update you can share on upcoming equihash improvements? Thanks very much
