## Why people recommend it

- Better price-performance than x86 (5 comments): "ARM has better performance per watt, which translates to better performance per $." ([source](https://news.ycombinator.com/item?id=48159634)) "the result was better performance at a lower price point" ([source](https://news.ycombinator.com/item?id=47283841)) "It's effectively better in terms of performance/price" ([source](https://news.ycombinator.com/item?id=47034531))
- Cheaper than Intel and AMD instances (2 comments): "One of the easiest hack to reduce your AWS bills is to migrate from x86 to arm64 CPU." ([source](https://news.ycombinator.com/item?id=46120683)) "It works out cheaper without the Intel / AMD "tax"." ([source](https://news.ycombinator.com/item?id=46219212))
