There’s no doubt that Ethereum is a hot topic these days, with the booming new cryptocurrency currently on the cusp of crossover and growth. even get ahead Bitcoin market capitalization valuation. Even if he suffered from a certain savagery volatility In recent times, the blockchain-based open-source currency platform is booming among hobbyists and enthusiasts looking to download and manage transaction workloads for the ecosystem, on high-end desktops. range. These machines may have originally been intended for gaming, but now their graphics cards can also serve as powerful processing engines for crypto mining, so much so that there has been use of NVIDIA and AMD GPUs , causing retail prices on basic products to explode. supply versus intense demand, market dynamics and rising prices. That said, the other metric, beyond GPU cost, that can act as a barrier to entry for crypto miners is power efficiency. Crypto mining workloads can strain cards and consume a lot of power. As such, clear performance-per-watt strengths are emerging among the current lineup of graphics cards and the results might surprise you.
HotHardware recently tested eight of the best gaming graphics cards on the market Currently, both in terms of raw hash rate (MegaHashes per second) and total system energy consumption under load, when mining coins based on the Dagger Hashimoto algorithm used by Ethereum (or ETH) . This may seem counterintuitive, but of course, not all GPUs are created equal and more powerful doesn’t always mean “better” when it comes to mining efficiency for minimal power consumption, while keeping your bill low. electricity under control. And when considering these GPUs at scale, since many people have literally humming card mining farms, every Watt consumed counts, in addition to the raw hash rate.
Logically, today’s best gaming graphics card, NVIDIA’s GeForce GTX 1080 Ti, also offers the highest Ethereum hash rate, but it also consumes significantly more power under load when mining, compared to mid-range cards. of range like the GeForce GTX 1070 or AMD Radeon RX480. Additionally, with a bit of memory clocking and power target tuning, the GTX 1070 can deliver a lot more performance, while maintaining a much lower power consumption profile.
When you look at all the numbers, and with all things Considered Including power consumption, the GeForce GTX 1070 cards appear to be the best GPUs in terms of performance per watt currently, with the AMD Radeon RX 480 and RX 580 coming quite close behind.
Either way, if you want to get into the mining game, with a little research and some tweaking, all cards can be designed to run more efficiently and deliver better performance per kilowatt hour.
