After I browsed http://www.mininghwcomparison.com, I found some GPU that had a 100+ hashrate, to 250Mh/s. I checked many other sites, and I didn't see any GPU that goes over 50MH/s, so is this site legit ? Is there any hardware that has a 100+ hashrate ?
These are all user-submitted values and also non-Ethash-based algorithms. For the most part, the users submitting 100 MH/s+ hash rates have indicated these are for multi-GPU systems. For example, someone has submitted this:
- ASUS 2х7990 1000 1500 win 8.1 pro 16.1 Ethereum 95Mh/s
The HD 7990 is, itself, two GPUs rolled into one. And this user has indicated that the 95MH/s is achieved with two of them. That means that each processor is cranking out a bit under 24MH/s -- more in line with what you're probably expecting.
Yes here is more gpu listed with 100+ hashrate. also you can search more gpu with hash rate their configuration such as Core clock, Memory Clock, Power consumption,Driver Version,Operating System for specific algorithm.
