There are a few different factors to consider when it comes to selecting the GPU to stick into your Bitcoin mining PC build. Firstly, you need to think about the hash rate of the card you are buying. This is better explained in the supporting Bitcoin mining article I linked in the intro, but put shortly its basically the rate at which your graphics card is able to put together the hash code that makes up the individual blocks in a blockchain, which in turn allow Bitcoin mining to happen.
Basically I’m talking about how long it takes for the card you choose to actually mine Bitcoin.
Then you have to think about the upfront cost of the card itself. Remember, we aren’t talking about gaming exclusively here, we are talking about an investment that you are hoping to see a return on, and with that in mind, you shouldn’t want to drop too much money onto a card if you don’t expect to see a solid ROI for a long time.
Then you have to think about your graphics cards power consumption – it’s going to be a noticeable cost that you will have to factor into all of your Bitcoin-related expenditure, especially if you are expecting to be running your Bitcoin mining rig all hours (hint, you should be if you are expecting to see a healthy return on all of your investments).
So, with all of that in mind, we have a couple of options for you here. If you are looking to splash any amount of cash no worries, and want to get the best performance out of the card that you buy then its obviously going to be the 2080ti. The strength of this card is within its processing power, as it’s going to be the quickest card on the market when it comes to putting out a hash rate.
It’s not just good for Bitcoin either, you could use this card on a number of different ecurrencies and see positive results when it comes to the turnover of the actual mining process, but be aware that this does come with some drawbacks.
The first of which is the actual price of this card. Remember when I said your selection would depend on your preference when it comes to the actual ROI on the card itself? Well, it’s hard to say how long it would take for this card to pay for itself when it comes to the actual mining process, as it all depends on the success rate of your mining and the price of Bitcoin at the time of mining. Basically, it could be a while before you make back the money you spent on the card in the Bitcoin mining game.
Plus, you have to add the actual power consumption of the card into your calculations. Sadly, the 2080ti’s processing power comes at a cost, and that’s the amount of power it takes to run the thing. Combine that to the (average) $1,200 price tag that is usual;ly attached to the 2080ti, and you have a long way to go in recouping the price of the 2080ti via Bitcoin mining.
So, what should you go for if you are looking for a more well-rounded card that offers a better upfront price, running cost, and decent hash rate? Well, you could go for the 1080Ti, the previous incarnation of the 2080Ti that also offers stellar performance, yet at a lower price.
You will be able to expect a hash rate of around 32 MH/s, which is really good for a dated card like this one, it means you will be able to rely on it for a steady rate of mining for a long time. You are also going to open yourself up to a litany of modification options that are only going to allow you to steer the 1080Ti more towards the end goal of mining.
You can buy these cards pretty cheap online, and they run even less expensive if you choose to buy a used version – just be sure that you don’t buy a card previously used by a Bitcoin miner, as they might not have taken great care of the card itself and it might not perform at its ‘as new’ standards. The card itself is less power-hungry than a 2080Ti as well, pulling in 250W of power – but again, your upfront costs will be lower than if you bought a 2080Ti, so you do have that to factor into your investment budget.
If you are looking for an AMD card to get mining on, then there could be a solution to be found in the Radeon RX570. Now, you might be thinking to yourself that as this card is less powerful than the Nvidia options I mentioned it wouldn’t perform as well – and you would be right in thinking this, but what you also have to consider is that you could, theoretically employ a number of these cards in different machines (all built to lost cost), and run several mining machines built out of lower-cost parts for a more productive mining bank.
There are obvious drawbacks to this approach (mainly in the power consumption department), but realistically you could buy several 570 GPUs for the same price as a 1080Ti, or even a 2080Ti, and up your mining process in a trade-off for less power. You won’t be getting a stupidly low amount of power though – an overclocked 570 could reach up to around 30 MH/s, so you just have to be willing to put the work in on overclocking your GPU.
Again, the choice is all down to you – but please be mindful of your budget, your ROI goals, and the price of power in the area you are looking to mine from.
