Interesting article:
Going into this I really didn’t know what to expect but these fairly simple tests suggest their is an economic advantage to running under ARM in the cloud. At worst you will see comparable performance at a lower price point but for some workloads you may see a significant performance gain – again at a lower price point.
20% performance gain at 80% the price is most certainly not to be sniffed at and for large workloads could quickly offset the cost of moving infrastructure to ARM.
With Apple moving to ARM for their Macbook line, and observations like above, high end ARM systems now seem to be a reality.
