GPU’s are your best bet when it comes to mining for Ethereum, and although it is possible to mine with a CPU, it’s not worth the electricity bills you’ll rack up. In terms of which GPU’s to mine with, Nvidia cards are generally better than AMD cards, and AMD cards are generally better than Nvidia cards when it comes to mining other altcoins.
However, when it comes to Ethereum mining, AMD cards are usually the best choice.
If you want to mine Ethereum on a gaming laptop, you’ll need to make sure that it has a good GPU. Many gaming laptops come with Nvidia GTX 1060 or 1070 GPUs, which are good for gaming but not ideal for mining.
However, some laptops come with AMD RX 580 or Vega 56 GPUs, which are great for mining.
The downside of mining on a laptop is that it will probably shorten its lifespan. The heat generated by the GPU can be damaging to the internal components of the laptop, and if you mine 24/7, you’ll likely see a significant decrease in the lifespan of your laptop.
So if you want to mine Ethereum on a gaming laptop, be prepared to replace it more frequently than if you were just using it for gaming.
