The M1 is great because it's fanless. AMD Ryzen is superb on workstations, but let's see if they can deliver a nice fanless or low power option. I hope they do.

- PragmaticPulp 6y agoThe Ryzen mobile chips, including the upcoming Ryzen 7 5800U mentioned above, have a low 10W (configurable up to 25W) TDP. That's in the ballpark of Apple's chip.
- my123 6y agoThat number isn't very meaningful - because it applies to the base clocks only... which is a big catch. Go beyond that and the power usage balloons quickly (won't repeat myself, see my other comment on this thread at https://news.ycombinator.com/item?id=25231798 https://news.ycombinator.com/item?id=25231798). On laptops, more power efficiency maps directly to increased performance (turbo clocks provide higher performance in bursts or at the expense of your laptop's fans sounding like a jet turbine).
- Kye 6y agoMy laptop with a Ryzen 5 4500U is only fan-free at idle. OEMs would need to do some serious work on cooling to make that work.
- gameswithgo 6y agoif 7nm Zen3 is close, then 5nm can probably match without a fan.
- api 6y agoIt’s almost like power efficiency is all about the process node. M1 is 5nm. It’s a great core but it’s power profile would not be so impressive at a larger node.
- floatboth 6y agoOnly the MacBook Air is fanless, and of course it throttles after a while, that's why there's the Pro with a fan on the M1
