that's not entirely true. they consume less energy in run mode, but in deep sleep the leakage currents are higher than with larger nodes. this is relevant for ultra low power applications, but those don't run linux anyway.
- SomeoneFromCA 6y agoThis must be the reason Ryzens idle at higher power than Intels.
- formerly_proven 6y ago20 W of IO die power regardless of idling seems the more likely answer.
- MrBuddyCasino 6y agoNo, AMD has always been worse than Intel at idle power consumption. I don’t know the reason for the difference.
- sudosysgen 6y agoThe reason nowadays is that desktop Zen chips run the I/O die at a worse node, to save money.
