noob here my thought is
1. arm is more power efficient than x64?
2. emulation + shift to remote development environments?
- albntomat0 6y agoIs the emulation environment really there? Maybe the nodejs (and everything not low level) can seamlessly develop on arm and ship on x64?
- remexre 6y agoI spent a week recently working from a Pinebook Pro after spilling water on my primary laptop; my workflow was already fairly SSH-centric, but I had fairly few problems with software compatibility that weren't fixed by binfmt_misc + qemu. (That week was spent mostly developing in OCaml and Lisp; I suspect if I were doing C++ or Haskell, I would've had a harder time.)
- tylerhou 6y agoOne theory behind ARM's power efficiency is that you don't have to waste power and area converting x86 into uops. But this is a constant overhead. It matters a lot on 5/10W TDP mobile processors, but matters much less on 45W TDP laptop processors.
- martin8412 6y agoHasn't it been a while since 45W TDP processors were common in laptops? My X395 uses a 15W TDP processor
- neogodless 6y agoNo. They are different use cases. Personally I prefer the 45W chips with higher base clocks at the expense of battery life. 15W is unsuitable for some workloads, though the latest 15W "U" chips from AMD are making some waves there.
- tylerhou 6y agoThe i9-9980H(K) found in high-end laptops has a 45W TDP. Granted, this is the most power hungry laptop processor you can find.
