Not necessarily. Zen 2 has high IPC and quite good efficiency. Someone posted leaked Userbenchmark scores of 4800U (8c/16th Zen 2 Mobile) APU scoring between Ryzen 2700 and 2700x (in a 15W TDP - which is normally configurable to 25W).
The thing is, we don't know if those results are accurate or not... we'll have to wait and see. Also, if the unit doesn't have a dedicated GPU, then its possible it will be TDP constricted to 15W and the cooling will be so poor it will barely allow the unit to sustain baseload speeds.
OEM's previous attempts at creating a laptop with only AMD apu resulted in sub-par cooling which also affected performance because they couldn't be bothered to create adequate cooling for an APU to operate at its maximum indefinitely (which is more than possible).
Only cases where we noticed the AMD APU was able to maintain its boost clocks and operational performance was in cases where it was paired with a dedicated GPU. Otherwise, if the unit only had an APU, the cooling was usually poorly done.
No. That's so 10 years ago. As most applications are multi-threaded, one would opt for more cores in limited TDPs such as laptops or smartphones. Low core speeds are power efficient.

4, 6, or 8 cores in the AMD version? A 15-Watt TDP 8-core was rumored...yeeeeman - Monday, January 6, 2020 - link
It would run at very low speeds all core, so a bit useless.neblogai - Monday, January 6, 2020 - link
Not useless, as cores can run at lower voltage then, thus performing better in multithreaded tasks- as proven by Intel's 15W 6-core.uzzi38 - Monday, January 6, 2020 - link
https://videocardz.com/newz/amd-introduces-renoir-...1.8GHz base. It'll be fine.

IPC v. Clock.Why is it people seem to struggle so mightily with these concepts?

It's confirmed. And it would be a lot better than what I have now.deksman2 - Monday, January 6, 2020 - link

I noticed with my 2700u if I throttle back the maximum CPU clock, more TDP got funneled into the IGP resulting in an uplift of gaming performance.Heat wise, never really noticed any issues, but that TDP wall was real.

Would like to know the weight too.skavi - Monday, January 6, 2020 - link
Would love if you guys could do the same thing with this laptop as you did with the Surface Laptop 15.hallstein - Monday, January 6, 2020 - link
This looks absolutely fantastic; coming from a MacBook user, I want one.
