- Hamuko 6y agoControlling one's destiny / not having to work with other companies since Apple loathes everyone else. Wouldn't surprise me if they also want to make the laptops even thinner once again.
- valuearb 6y agoPerformance per watt is the biggest advantage, Apple will get fast laptops with extremely long battery life. Cost per performance is a very close second, ARM CPUs are a fraction of the cost of Intel CPUs. It’s also speculated that with active cooling ARM will enable high performance Macs at a lower price point. It’s very unclear how well they will be able to match AMD and Intel at the highest performance levels.
- aspenmayer 6y agoPerhaps a combined SoC with both ARM and x86-64 cores, with independent switching like Apple already has for GPU integrated/discrete graphics switching. I think this would be a convenient middle way through this compatibility challenge. https://support.apple.com/en-us/HT202043 https://support.apple.com/en-us/HT202043
- eqtn 6y agoThat would increase the cost, to include both x86 and ARM processors.
- aspenmayer 6y agoNow we know there will be a dev kit, new macOS, and that the new Macs will natively run iOS and iPadOS apps. Rosetta 2 will handle compatibility. https://news.ycombinator.com/item?id=23604060 https://news.ycombinator.com/item?id=23604060 https://news.ycombinator.com/item?id=23603852 https://news.ycombinator.com/item?id=23603852 https://news.ycombinator.com/item?id=23603866 https://news.ycombinator.com/item?id=23603866 https://news.ycombinator.com/item?id=23602434 https://news.ycombinator.com/item?id=23602434
