CPUs & Graphics cards: suitability for LL

[m654321]

seems like the Rizen familly (R5) for equivalent "range" of CPU Versus Intel's (i5) are faster for heavy workload and almost on par for regular stuff

That's useful to know - many thanks.
I'm now looking at energy consumption - though either an R5 or i5 setup might be suitable, it has to be one that's going to be low on energy consumption, when idling or not playing games.  I notice the Intel chips have a big difference between the 'baseline' and 'turbo' e.g say 2.4 & 3.8 GHz, but Rizen chips have less difference. I guess this means AMD chips are more energy hungry, which is what I've heard.

Though my dead Asus G750JS was rated at 2.4/3.5GHz, the Htop app showed it would idle at significantly less than 1GHz, thereby saving energy when not busy.  Do Rizen, or AMD chips in general, tick over at a low speeds when idling, or doing simple admin tasks, or do they just run faster most of the time, irrespective of the load?
