I really think we've already eclipsed that "generational gap" with all the massive increases in efficiency in the last year or so. But I'm glad they're not updating nonetheless. For a variety of reasons.
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.
It's a completely different discussion if you throw ARM into the mix.
And given some recent news about Valve working on an ARM emulator and funding Arch Linux to help them start supporting ARM as well they might be working towards that. Though if that is for the deck 2 or something else further in the future is yet to be seen.
It's rumored to be for new standalone VR.
But, well, future is a long time, especially on Valve Time. ;)
Exactly. They're already working on ARM support.
surprisingly not most of the time I checked.
Laptop/Mobile x86 seemed rather competetive to Laptop/Mobile ARM in performance/Watt
Well, let me rephrase it: it's a completely different discussion if you want to run Windows games on ARM without ridiculous performance losses due to translation from x86.
Until we get Proton running with near-native speeds on ARM like on x86 perf/watt isn't really that important.
