Hi Guys,
Until know I mostly bought GTX 1660 Super for my rigs but in term of efficiency (hashrate per watt) I think it's not amongst the best GPU to mine ETH. After OC with a GTX 1660 Super I got in average 31.80 MH/s and 70 Watts so its efficiency is approximately 0.45 MH per Watt (31.80/70).
I realized that with a RTX 3070 after OC you got in average 62.30 MH/s and 115 Watts (with the new absolute core clock feature of HiveOS) so its efficiency is approximately 0.54 MH per Watt (62.30/115)
.
Yes the RTX 3070 is around 2,000$ on Ebay almost double price compared to the GTX 1660 Super but you also get almost double hash rate. Also I saw Red Panda Mining building a 6 X RTX 3070 mining rig with the same components that I use for a 6 X GTX 1660 Super except for the PSU, I need a 1300 W 80+ Gold (I normally buy 1000 W 80+ Gold for my 6 X GTX 1660 Super, I like to have a little extra power).
I think from now on, I will start to buy RTX 3070 GPUs considering in average the efficiency for RTX 3070 is 0.54 MH per Watt VS 0.45 MH per Watt for the GTX 1660 Super. We are talking approximately about 20% efficiency improvement!
Please let me know if I forget something in my analysis?
Thanks
You are wrong, there is a way to go lower than 70watt on those gtx1660 super it's what I used for my rig too, after watching some YouTube video from a Caleb guy there is a way to go lower using Trex absolute core clock, 20% less watt is possible.

The
Minerstats 3070 is without a doubt the best graphics card on the market for most people. It delivers performance on par with the
3060 ti ftw ultra at less than half the price, truly bringing 4K gaming to the mainstream for the first time.
What are you saying? Minerstat don't build or manufacture graphic cards themselves they are just building mining rigs and sell, also 6x RTX3070 build is over 9,000$ that's a mess, waste of money.
