One of the only downsides of the Ryzen Z1 Extreme - it uses 4-5+ watt minimum at idle which isn't ideal, hoping they improve on that with future handheld SoCs.

It says a lot about the state of Intel when thier using time up in a major CES event to talk about what are essential just 'BIOS fixes'.

Yes, but I am not sure there is a solution to this.
The problem is "Quantum Tunnelling". Particles can jump over tiny junctions. It's a quantum effect and there is no stopping it. The smaller they make transistors the more this becomes a problem. We see this as leakage current. The smaller the transistors, the more they leak power, and power leakage generates heat. So the smaller the transistors the more heat they produce even when they are "off". The way intel is tackling this is to add cores that are less complicated, have fewer junctions, so leak less power. The way AMD tackle this is to tell users to add a bigger heatsink.
But yes, it is a problem. I'm just not sure what AMD are going to do about it, if anything.

A lot of it is due to the "package power" utilisation with the separate IO functionality, etc. though actual power consumption at the wall, depending on PSU efficiency and matching to the system, isn't massively different across Intel or AMD - though some CPUs like the 7900X can be quite a bit higher than other similar CPUs.
