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

RTX 3070 and 3060ti are almost the same in ETH, and yes, both are the best hashrate per watt available

I have both
3060ti - 61.10Mhs using 130w on the wall
3070 - 60.19 using 134w on the wall

I never reached 115w on the wall

Both are good cards, doesn't get too hot like 3080s, easy to reach at least 60Mhs, will have a great resale value
For me, 3060ti is a little better because of the price, which is supposed to be cheaper than 3070, but with this insame market, I think both have the same price, and with both you'll have a great rig in terms of efficiency

True definitely of efficiency are the RTX cards, my gtx1660 super is doing 32mh with 75watts and RTX3070 doing 61mh at 132watts, the bigger cards are more power efficiency all the way, this is not just a good time to build a mining rig if your I'd have build 8x RTX3070 mining rig but I will wait for drops in GPU value

I got 1x Gigabye Gaming OC 3070 runs 62.88mh/s at 124w, then 2x Gigabyte Aorus 3070 one runs 63mh/s at 121w and the other runs 62.9mh/s at 124w in Pheonixminer.
All up in old as 1366 mobo and first gen I7 cpu (ie not power efficent) runs 490w from wall.

The Gaming OC runs so cool thou like 43-44c just with autofan speed, the Aorus one I have to put to 65% and other to 67% fan speed just to keep them at 49-50c.
All 3 cards really quite compared to some thou.

RX 5600 44mh with 80 watts = 0,55mh per watt
RX 5500 28.5 with 50 watts = 0,57 per watt

but thats are stats from other users, i don´t own 1 of that cards to test, but it can be. Maybe someone with this cards can tell us more?

It seems that you are telling us watts from HiveOS. I have the same but there is one problem - if you want to get true values - use wattmeter. In fact it is 100-110wt for 5600 and 75-80wt for 5500.

About the best efficiency - 3060ti-3070 are the best for today. They easy to config and don`t need any flashing as RX5600.

Nope, many users tell that. But i don´t own one of this cards so it can be higher.  :D
You have tested an RX5600 or RX5500?

3070, 3060ti and RX5700, RX5600, RX5500 are the best GPUs for Ethereum mining. In my country, these cards are not sold in shops, and the RX5700 seems to have been discontinued. But the profit may change due to a change in the Ethereum algorithm and an increase in the network hashrate.
RTX 3070 are very expensive, you need to consider how long this energy efficiency will pay off

mak013 is right, people are saying 80w for RX 5600XT, but it's on software, the power on the wall is higher, I have a 5600xt, and never reached these magic values people say
I don't own a RX 5500 but I doubt about 50w on the wall

My 5600xt is using 98 W on Hive OS, but 115w on the wall (no bios mod)
 
Nvidia cards stats are closer to software than AMDs, so I vote for 3060ti and 3070 for the best efficiency, and another good thing about Nvidia is you don't have to bios mod, only overclock the card

I've stopped believing in the power draw that mining softwares used to display, on my rx580s I lower their core voltage to 750mv just for power saving sake and from wall these cards still draws over 100watts thanks to wattmeter

It means only one thing - we have lots of newbies that don`t pay electricity bills. I have such GPUs and tested it with wattmeter that`s why i know what i`m talking about. In RaveOS, HiveOS NVIDIA GPUs shows about the truth(but even with NVIDIA you have make some work to show true values) but AMD have huge difference between mining OS and wattmeter.

I think with the new Core Clock Lock support for Nvidia feature from HiveOS released April 13 2021 you can get 115w on the wall for your 3070. The new feature allows to reduce the power consumption significantly without losing hashrate.
https://forum.hiveos.farm/t/system-changelog-and-news/11778/41

With that new feature my RTX 2060 was using before 124W at 31.46 MH/s and now it's using 86 W at 32.18 MH/s (it increased its hash rate).

Pretty amazing!

I think to build a 8 X RTX3070 mining rig you need 2 PSU or one PSU higher than 1300W?

8 X RTX3070 => 8 X 115W = 920W + the power for the other components maybe around 100-150W + you have to apply the 80% rule + a small margin in case for voltage sag.

I heard that I should avoid Gigabyte GPUs, it seems you don't have any issues with them?

Yes this is why that I don't rely on the stats you can find on websites like https://www.stelareum.io/en/mining/gpu.html or https://minerstat.com/hardware/nvidia-gtx-1650 but I guess these are good estimates.

I think for $100 or $200 more you better buy GTX 1660 Super instead of RX 5500 XT which has few mega hash rate less to mine ETH.

FP91G unless I am wrong you cannot (maybe for exceptions) find a GPU in any shop in the world, most of them are sold out, you have to purchase them online. I live in Canada and made few shops and they all told me they are sold out and some of them have a waiting list starting from December and some stop taking new names. It's a world wide shortage! :-\

Agree it's important to have a power meter but when you go above 15A you cannot use these usual model you plug on the wall you have to use a PDU with a power meter integrated or a box meter which you need an electrician to install.

A youtuber claimed that GPU can still be purchased at good price on best buy somehow and there is another youtuber (lady) that but 12x RTX3070 through best buy too, I don't know how they pull the stunt or trick, where is philipma? I'm guessing I can get an answer from you about this

Sorry mate but no, yours are not absolutely the best. I just compared your numbers with 2 of my 3080s I have. One consumes 241W, another 220W, both work stable for months giving around 100.7 MH/s. According to my calculations efficiency is 0.42 - 0.46 MH/w, which is the same or slightly above your cards. I want to increase it further by playing with downvolting, but that's another topic.

I prefer having top cards to save on rig space, plus their liquidity in the future will be way better (as my 1080Ti's have already proven).

This is just one of the choices. I prefer low and medium level GPUs. With top GPUs we are getting problems with PSU and cooling. And if 1 rig is down - it becomes a big problem. But on the other hand - saving space and top GPUs for a long time. Everyone choose the way that is better for him.

Yeah and that's exactly why I didn't want to derail this thread by further evaluating my reasons, just briefly mentioned them  ;) We're talking about power efficiency here, after all.

I prefer cards in middle wattage consumption like 100-200watts.

Maybe I didn't explain well Commie, sorry

I have 3080 too, making 99Mhs with 240w on the wall, it's a beast for sure, but my point is: 3080s are hotter than 3060ti and 3070, the memory on 3080s and even 3090s are hard to keep cool
In this thread you can check: https://bitcointalk.org/index.php?topic=5287329.0
A lot of people have problems with hashrate drop

While with 3060ti and 3070 there's no such problems, the point on my post:

I'm just talking about 3080 heat

And I continue to recommend 3060ti and 3070, easier to find, easier to deal with power, less PSU cables, no hashrate drop, both are great to make a 6 card rig

But of course I like 3080, 100Mhs is awesome in one card

Agreed, heat is an issue. Big one. My cards run at 96-98C mem junction temps (after thermal pads change). That's high, but then I live in tropics, no choice. Maybe I will go for immersion cooling once I have 20-30 of them, but it might take a while LOL

Apparently people are camping in front of Micro Center shops in the US to have the chance to buy one new GPU model. I would be really surprised that you can buy 12x RTX3070 on Best Buy plus if I am not wrong, when you shop online on Best Buy you have a limit of number of GPU you can buy so it would be astonishing that you can buy 12x RTX3070 in a Best Buy shop.  

Thank you everyone for your participation in my topic. I feel much more reassured now to slowly buy my new mining rig with RTX 3070 GPUs. This forum rocks!!!

Well if his cousin or brother or dear friend works for Best Buy it can be done.

I manage to fight my way past the Best Buy bots and get a 3090 for 1850 usd .  Was supposed to come to the store on a Saturday .  Sat morning when due they said we are sorry  we are canceling your order.

Having had people in my family work for Best Buy I know what clerks do at stores.  When a monster hot item come in they call a friend and say I will bring the item out and put it on a display shelf you grab it and go pay for it.

And they get a 3300 ebay prices 3090 for 1850.

I went to Best Buy's blogs and complained. They offered me a 50 dollar gift card. I said the story above and they offered me a 100 dollar gift card.

So I am pretty sure  that the guy claiming to get 12 crds does it like I describe.


Or he has 50 bots doing it for him.  What ever.

My position on Best Buy is they owe me about 3300-1850 = 1450- 100 = 1350  in moral court.

If you can get your hands on RTX 3060ti they make sense more than RTX3070 because their performance is the same but 3060ti use less power and more cooler when working, try staying in between most powerful cards and the weak cards if you don't want to deal with heats

Nah no problems at all, plus the 2x Aorus i got 4yr warranty on, the GamingOC  i got 2nd hand off mate so was too late to claim the 4yr.
Today was fairly hot so the Gaming OC got to 50c and the others to 52c. Turned the fans up on the 2x Aorus just for 1/2 the day.

Hello,

    I get chance at low price to buy one display card.
1) 3060Ti with Price USD 900
2) 3060 with Price USD 680

As I know 3060Ti about 60Mh/s while 3060 only 48Mh/s
Which one should I/you would buy?

Is nVidia going to nerf 3060 hashrate?  I am nervous... ???

Thank you Ceyflix-Rez. I have bought a commercial Mitsubishi AC so heat it's not a problem but less heat means less AC needed so it's good to save money on electricity cost!

I think Nvidia have said that they will cut in half their mining efficiency for their cards but they said that they will do this only on new version of cards produced so that means the hashrates will stay the same in the cards.The 3060 Ti is way more efficient in mining than 3060 so you should buy that as that 220 USD price difference will be covered during the mining operation.

Lots of answers, and nearly correct. The 3070 is a fine card, but the master of hash / watt ratio is the 6800.
It gives around 63 MH/s +-1 MH/s for around 100 - 110 Watt. Not more to say.

But it's not power on the wall, it's only on software
Here's a video showing thath 6800 is using 145w on the wall: https://www.youtube.com/watch?v=hMDHQBNyVNs

3070 and 3060ti uses less than 145w on the wall

If you have someone measuring 100w or 110w total on a Kill a Watt for example, I would like to see how to get this result, it would be awesome  :)

I have just been browsing on Ebay and the 3060 Ti is almost the same price as the 3070 and in many instances the 3060 Ti is even more expensive.

@rdluffy

Good point.
I will check it today.

The Minerstats 3070 (https://www.digitalcryto.com/product-tag/rtx-3070-minerstat/) is without a doubt the best graphics card on the market for most people. It delivers performance on par with the 3060 ti ftw ultr (https://www.digitalcryto.com/product/evga-geforce-rtx-3060-ti-ftw-ultra-8gb/)a at less than half the price, truly bringing 4K gaming to the mainstream for the first time.

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.

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.

3060 cards can't get nerfd after you buy them, if it's LHR version it's already LHR out of the box, check the corner of the package it should say V2 if it's LHR but with V1 we can still use HDMI dumble to achieve  better hashrate speed, it's 50MH per 3060 if it's not LHR with 110watt power consumption.

The best card to buy is this card.


https://www.cdw.com/product/nvidia-rtx-a2000-graphics-card-rtx-a2000-12-gb/6819614?pfm=srh


if you can get it in stock it can be as low as 600-650

it uses no wires just the slot.
it pulls about 69 watts
it does 40mh

but find it in stock at 600-650 or finding the 6gb version in stock at 550 is really fucking hard to do.

https://www.cdw.com/product/nvidia-rtx-a2000-graphics-card-rtx-a2000-6-gb/6810376?pfm=srh


I have 56 of the 6gb cards on back order.

they will go into 12 card cases.

do 480 gh I paid 550 a card  or 6600 plus  1200 = 7800 for a 12 card build that does 480mh at 960 watts.

Amazing info!
Thank you philipma1957.

Unfortunately, The Merge will happen soon with Ethereum Consensus Mechanism so we won't be able to mine ETH with graphics cards anymore so in my humble opinion, buying graphics cards now is not a judicious investment decision on long term. When you look at all the other coins to mine, their daily volumes and market caps and sooooo tiny compared to ETH and most of them don't have real use cases (except to be an investment vehicle) that I'm pretty sure our mining profitability will drop enormously, I'm expecting maybe 50-80% drop.

This is why for the last 6 months, I have been studying Ubuntu Server and Rocket Pool documentations and started to run validators on the ETH beacon chain. It's the future, no doubt. It's crazy just on Rocket Pool, every day, big dogs or institutions (banks, insurance cies, hedge funds etc), are staking in average 2-3 millions USD of ETH value into the Rocket Pool protocol.

And and Nvidia have a lot to lose if eth goes full on pos.

I smell a hybrid system coming up.

The 80watts from RX5600 and 50 watts from RX5500 are not from the wall this are watts power shown in miners you need wattmeter to measure the exact power consumption from wall.

In this case, the obvious choice is the RTX 3060 Ti because of the lower purchase price and depreciation.

Or you can just add 40w or so to the reported power, then multiply it by 1.1x for 120v / 1.08x for 240v (if your PSU is 80+ Gold).

I got 13 of these yesterday.

https://www.evga.com/products/product.aspx?pn=12G-P4-2263-KR

I paid 431 a card with six months no interest to pay.


They do 37 mhs at 85 watts. 12 gb ram 3 year warranty these are pretty good.

They are on ebay for 488-490


https://www.ebay.com/itm/284661293897?

https://www.ebay.com/itm/294726907602?  I have purchased from this seller he was good.

85w software reading, never ever from the wall. They can maybe do 37mh, but normal hashrates are 35 - 36 long term stable

My RTX 4000 series take around 90w from the wall for 37.28mh out of the box.

My 3060's v2 are doing 37mhx @ 115W (software) Humm can I get those result... what is your settings? Im using HiveOS

He's talking about 2060 and you're asking him about 3060 V2? ??? ??? ::)

Here's a link to help you on your 3060V2
https://www.hashrate.no/3060v2

Damn philipma1957 you made me look up the GPUs and I finally bought one RTX 2060 12GB for 700 CAD. Same model but the 6 GB few months ago I paid 1 200 CAD.

Yes the PoS for Ethereum should come in June but I still think mining other altcoins with GPUs will remain profitable even post ETH 2.0.

The problem with staking ETH to run a validator it's because we need at least 16 ETH for one validator on RocketPool it's very expensive. Without running a node you can stake as little as 0.01 ETH on Rocketpool and you pay fee between 5 to 20% to the node operator but the actual % APR is just around 4% and the RPL tokens APR is around 14%. Mining ETH with GPUs is more around 80% APR.

But if you expect ETH price to go around 12k after The Merge and RPL token around 500$ then it will become really profitable to stake ETH but for now we have to be patient.

philipma1957 I just received my EVGA GeForce RTX 2060 12GB XC GAMING and after many OC trials I got 29.79 MH on Ethash with a CORE of -512 and a MEM of 1024 at 100 Watt (on GMiner software).

The memory is Micron.

How do you obtain 37 mhs at 85 watts?

For now, in term of efficiency (hashrate per watt) it's not so good with only 0.2979 but in terms of hashrate per GPU cost (29.79 MH / 700 CAD = 0.0426 MH / 1$) it's pretty good. Fortunately, I pay 0.10 CAD per kWh.
