Nothing yet surpassed Zen2 low power efficiency in the SD. And by low power I mean under 10W power/performance.
New chips scale quite a bit better above 10W though.
Also I'm not sure if that's actually the HW limitation or just Valve tuning of the power behaviour. It's possible they can throw in Zen5 and tune it to that efficiency level while getting significant performance uplift over Zen2 at the same power.
Regarding GPU we will need much faster memory support to get any significant advantages even with RDNA4 as most iGPUs are starved for memory bandwidth anyways, not saying that RDNA4 wouldn't be an improvement, just that it won't be as big as a leap as it could be with faster memory.
Qualcomm, Intel and AMD have all released chips that blow it out of the water.
Snapdragon Elite, HX 370, 238V, etc.
Qualcomm is Snapdragon, and that's ARM, which means half of your games will crash at random in the first 30 seconds or not boot at all
Intel has not done what you claim they have
Intel is claiming that with the upcoming Arrow Lake series of CPUs will seriously cut down the power budget. Important clarifications on that, the TDP of Arrow Lake is still around 150W TDP but that doesn't mean it'll pull the full 150W all the time, and wait for third-party benchmarks before believing anything they say. Still if what they're claiming is half true mobile devices could be getting a huge boon.
It doesn't always scale down though. There's always an efficiency curve so we really can't speculate. I agree, we have to wait and see.
