Is there a database that lists GPU models and their approximate mining hashrates?
it does seem the above mentioned lists are no longer available. so try this one, its up to date and recent. GPU hash comparisons
Try this one: http://cryptomining-blog.com/category/mining-hardware/
Though it is not perfect, it covers most of the GPUs.
there is a database of GPU different models and their hashpower (with the usage conditions) check http://www.mininghwcomparison.com/list/index.php
mininghashrates is a database with GPU hashrates that can be filtered and searched.
This is a zcash hash rate list, but it is pretty comprehensive. I use mainly to check wattage usage.
GPU lister is a search platform for different graphics cards of different credential with their configurations such as Hashrate, Core clock, Memory Clock, Power consumption for specific algorithm and many more specifications.
I request all of you to visit the website and submit your best hashrate for others.
