Speculation - 4800H cpu is what next gen consoles will have.

"Probably energy efficient for an AMD mobile part... AMD has never had notebook CPU's with acceptable idle power, which isn't an issue for consoles or PC of course.Intel however is still a step ahead of AMD in this aspect." - Permalite

^ a by-product of the infinity fabric design they choose.   (race to idle, wasnt something AMD was good at)

This will be my last post for about a week or so as I am going on deployment.

The infinity fabric isn't what it is holding AMD's idle power consumption back, it plays a part... Sure.

AMD has *never* been competitive with Intel on Idle power, even during the Turion era.. AMD isn't as aggressive as Intel on power states, doesn't power gate parts of the chip as aggressively as Intel.

This has been a theme for AMD's mobile efforts for over 15~ years.

However they are aware of it, and have worked at it.
Supposedly they "fixed" this issue (alot of it is apparently how fast/slow it enters/exits idle/turbo, which is now x5 faster):
That and 20%+ lower soc powerdraw (reduced how low things can go and funktion), ontop of 2x power effeciency (mostly from 7nm node)...

Of course they are working on it, but Intel has invested extensively in reducing idle power... To the point where they are even working with display manufacturers to decrease panel power consumption with Intels chips.

AMD will still have a long way to go on fixing their idle power consumption woes, even after Ryzen 4000 series drops... But without question, they will likely have the performance edge either way.

Edit:

Also Remember this for a console part (plugged in).... that really doesnt have any barring on Xbox Series X or Playstation 5.
However I remember there was some talk about next gen consoles being alot more "green" in that idle power / sleep modes, would be drastically improved.

That is why I stipulated prior that it's not really a big issue for consoles or PC.

Also with the 3000U series, AMD idle power wasnt so bad (they improved it a decent bit, with the 3000 series).
Something like the ThinkPad X395, with a 3700U has 14,5+ hours battery life (while running MobileMark 2014).
(yes supposedly the intel version ( i7-8565U) of the laptop with same battery, lasted like 17hours)

Still any laptop that can run 14,5hours straigth in a benchmark, has decent enough battery life no?

I have a Ryzen 2700u, the 3000 series was essentially just a die shrink of that, the idle power was still shit, I could go more in depth, but I am running out of time.

14.5 hours is good, that is decent battery life, but you could potentially achieve that with better power characteristics and a smaller battery which could potentially lower costs and thus the price... Or give you more battery life overall.

Fact is, Intel will be beating AMD's 7nm chips whilst still stuck on 14nm on the power consumption side of the equation, AMD will of course win in CPU performance and absolutely dominate in GPU performance.
Not entirely sure what the video engine is on the refined Vega GPU with Ryzen either, could have a few caveats there.
