A mining rig with 8 of these cards, riserless board would be great with 0.72 Ghs speed of mining in a single board. It is a lot better than E3 Antminer and it can also mine other coins, it should also shine on cryptonight algorithm. It is expensive to build such rig right now wih profitability down but for any believer in crypto it is wise to build such rig.
Dude, you mined any cryptonight coin recently? They are asic-ed to fook.
Even if these 7s double the CN hashrate of the 64 and power use stays the same (neither of which seems likely), you'd still only be breaking even on electric costs.
I am mining since 2014 but I already noted only build one for those who believe in the future of crypto not the ones who are in for the quick buck. Crypto needs real hardcore miners and not kiddies who want to make that quick buck. Mining is not for everyone in case you haven't noticed yet.
I am mining cryptonight Heavy with Nvidias still do 500 h/s with a 1060.
Kiddies? haha. If only! Nice to meet a real hardcore miner though. I have been mining for about the same time, but CN has never been so bad. Now a £2k Vega rig will 'make' c.$40 usd a month, and costs £90 a month to run here in the UK. The maths does not look good.
Indeed, you mention the future of crypto, but there cannot be many who are willing to run at such a loss. I fear many of these Pow networks will fall, as they require running at a significant loss. It is not a practical place to be.
