Part of the reason why both new and second hand graphics cards are so hard to find or inexplicably overpriced is that cryptocurrency enthusiasts are snapping each and every model that can be used for mining purposes on coins that use a proof-of-work consensus algorithm to confirm transactions.If you're looking for the best graphics card, whether it's RTX, GTX, or one of AMD's latest Radeon Navi cards, this guide will help you decide on the best card for 1080p, 1440p, or 4K gaming.And it was made to make Bitcoin mining more democratic by creating a version of Bitcoin that is mineable with GPUs. In context: Most people who wanted to buy a high-end graphics card last year had trouble acquiring one, and it doesn't look like that situation will improve anytime soon. In this article, we will be going more in-depth on why Macs aren’t the best choice for bitcoin mining. You will need equipment (a mining ASIC) that is dedicated to mining cryptocurrency. It is technically possible to mine bitcoin on Mac or MacBook Pro these days however, it is no longer profitable.Cryptocurrency enthusiasts are used to the rollercoaster ride, but you may not be and as such it's best to temper your expectations.We also know that not everyone is happy about the use of graphics cards to mine cryptocurrency, but the situation won't change much until at least 2022, when Ethereum's multi-phase transition from proof-of-work to proof-of-stake will be completed.You can also think of it from a different perspective - assuming a best case scenario, you have the possibility of recouping some or all of the cost of your graphics card and even make a small profit, by using it to mine when you're not using it for gaming. Chances are the current situation is just a repeat of what happened in 2011, 2014, and 2017, with a good probability that it will crash again. In this article we explain the advantages of using an external graphics card with your Mac or MacBook, and round up the best buying options currently available.Before we take a look at the best graphics cards for mining, it should be noted that even as cryptocurrency prices have recently surged to record levels, their volatile nature makes it hard to predict what will happen in the near future. Power consumption is also a major concern, as it will directly impact how much profit you can make.Welcome to our guide to Mac eGPUs. The best mining GPUs need to backed up by enough VRAM, and gaming performance isn't necessarily a good indicator of mining performance. Because of the way things work in the crypto mining space, blockchain developers introduce limitations for what you can use.
Best Graphic Card For Mining 2018 Mac Or MacBookHowever, the typical power draw for that hash rate range is 220-250 watts.Like the RTX 3090, the price is the highest disadvantage, as you would be hard pressed to find it at the MSRP of $699. Again, this is what can be achieved with proper overclocking, voltage tuning, and cooling solution, and that will also depend on the silicon lottery. High performance: RTX 3080 and Radeon VIINvidia's RTX 3080 is a close second to the RTX 3090, with a hash rate of 95-100 MH per second. In the case of the RTX 3090 graphics card, it happens to excel at both gaming performance and mining performance.Mining on an RTX 3090 using the DaggerHashimoto algorithm (Ethereum mining) can yield around 120-125 MH per second, at an average power consumption of 285 watts, given some overclocking and voltage tuning.Given the high price of the RTX 3090 that's further inflated by GPU drought and scalpers, breaking even on it may take between 237 and 278 days depending on the cost of electricity in your region (assuming $0.10 to $0.12 per kWh), and assuming the price of Ethereum doesn't dip below $1,900.Time spent gaming on it will also eat into your potential profits, but this card will run most games out there at 4K, with the notable exception of Cyberpunk 2077, where even the magic of DLSS won't help it muster a smooth 60 frames per second at all times. Moderate performance: RX 6000 series, RX 5700 XT, RTX 3070, RTX 3060 Ti, RTX 3060, RTX 2080 Ti, RX Vega 64/56AMD's Big Navi definitely doesn't disappoint when it comes to gaming performance as you've seen in our reviews of the Radeon RX 6800 and RX 6800 XT, with the RX 6900 XT being just a slightly beefed-up version of the latter. That said, the Radeon VII can be very hard to find, and eBay prices are currently hovering above $1,500. But thanks to AMD's use of HBM2 memory, this is a great performer for mining Ethereum.Careful tuning can yield 95-100 MH per second, at a power consumption of 190-200 watts. This was AMD's second attempt at making the Vega architecture shine, and ended up underdelivering on its promise to be competitive with Nvidia's RTX 2080. Unity download for macGetting these cards second hand can cost more than they did at launch, but breaking even with mining on them can be done within 6 months, which makes them a less risky proposition given the volatility of crypto prices.Nvidia's RTX 30 Ti are quite close in terms of both gaming and mining performance, with the latter also costing a bit less. Power consumption figures vary a lot with these GPUs as it will depend a lot on the silicon lottery, but typically they need 130-165 watts. They are certainly among the best GPUs in terms of hash rate per watt, while also being great performers in 1440p gaming.The same can be said about Radeon Vega 64 and Vega 56, both of which can achieve a respectable 45-52 MH per second with proper tuning, which will mostly depend on how much you can overclock the HBM. Time to break even is around 180 to 236 days, assuming you can get your hands on one.For people who are holding on to RX 5700 or RX 5700 XT, these two cards can achieve a respectable 50-56 MH per second, all with a power draw of 120-155 watts. If you can get your hands on an RX 6800, that's the clear winner among the three in terms of price and energy efficiency, so it should yield the best mining results. AMD confirmed as much when they said had no plans to nerf the mining capabilities on its graphics cards, like Nvidia supposedly planned to do with some RTX 3000 series chips.The most you can expect to get out of these cards is 60-65 MH per second with a power consumption of 160-190 watts. Pivot tables on excel for macBuying one at the moment requires an arm and a leg - around $1,300 on eBay - but you can break even on it in after mining for 180-190 days. It was always a great 4K gaming card and it also manages to achieve a mining hash rate of 55-60 MH per second, at a power draw of 155-180 watts. These are among gamers' top choices for a gaming PC upgrade, so their availability may suffer more as a result.The RTX 2080 Ti wasn't great value when it launched, and that hasn't changed. However, due to their inflated pricing, time to break even is anywhere from 225 to 242 days. It's also worth looking at the Nvidia GTX 1660 Super, which can achieve a hash rate of 26-32 MH per second at a power draw of 70-90 watts.Better yet, AMD's Radeon RX 5600 XT can reach as high as 42 MH per second while drawing 105-115 watts. The same can be said about AMD's Radeon RX 580, RX 570, and RX 480 graphics cards - we're talking about the 8 GB variants, of course.Even with inflated pricing, these graphics cards allow you to break even in 4 to 5 months. If you happen to have the 6GB version, you can achieve a modest, but still respectable hash rate of 25 MH per second, with a relatively low power draw of 90-100 watts.
