Is the number of shares proportional to the MH/s?

Hello,

I have a brand new rig and I am surprised by the result.

Is it normal that the number of shares is not proportional to the MH/s?

Below are my number after 33 minutes, mining ETH on HiveOS
 - 1x NVidia RTX 3080, using TRex : 83 MH/s : 1042 shares (31.57 shares per min)
 - 6x AMD RX5700XT, using RedTeamMiner : 315 MH/s : 805 shares (24 shares per min)

The number of shares of my AMD seems really low. If the number of shares is proportional, shouldn't I have instead at least 3900 shares?

What are your though?

Thank you in advance,

Best Regards,

Silat

All shares are not equal.

No unless the difficulty is fixed however on many pools the difficulty varies with hash rate. Shares carry a different weight. If you send 1 share of 1000 difficulty it’s the same as 10 shares of 100 difficulty. Why do they do this?

It’s to prevent server laggy and reduce variance. Each pool wants to maintain a certain shares per minute and adjust the difficulty until it achieves that desired result. Hence why your shares per min are similar on your 2 rigs which hash at different speeds. If a faster miner sent too many shares it would just slow down the pool. And if it took forever for a slow miner to send a share there would be huge variance at the beginning.

The higher your MH/s the more shares you will get, your miner will solve more blocks faster, assuming you have the double hashrate of that 83MH you get from the RTX3080 you will have over 2000 shares already, the bigger the megahash the better
