Whilst the 4800H is beefy for a notebook, it's mid-range on the PC... And depending on clocks, maybe even low-end.
AMD typically reserves up to 50% of the APU for the Graphics, that has been their design philosophy since they started making APU's with their Fusion initiative.
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.
The hit to cache shouldn't have a corresponding hit to performance, the IMC and uncore is on die which will help massively with reducing latency, which is a big deviation from Zen on desktop.
Sometimes it even reduces performance.
Higher clockspeeds but with a smaller chip doesn't mean it will be cheaper to produce. |
Mass quote of text.... Im not sure how to cut out parts when you multiquote so the entire thing just goes with.

^ a by-product of the infinity fabric design they choose. (race to idle, wasnt something AMD was good at)
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)...
This chip is gonna change AMD in the laptop scene imo.
Its gonna be competitive when it comes to battery life too.
We need to wait a few months to see it in hands of reviewers, but I believe the idle power draw wont be a issue.
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.
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?
