Sure your device might have a fair bit of horsepower, but also keep in mind that skyrim isn't capable of using ARM cpus without hardware emulation (currently) which adds SIGNIFICANT overhead. Not only that, but it wouldn't be able to use more than one cpu core. As for which one, your guess is as good as mine.

Also cellphone ARM cpus don't have layer 2 or layer 3 cache, and some don't even have layer 1 cache. This alone is enough to basically negate any possibility of a cellphone running desktop workloads.

You also didn't account for any performance required to actually render things. The cpu on the phone may be capable of the simulation calculations, but it straight up doesn't have the horsepower to do those AND render the simulation.

There's a reason that phone cpus draw 5W at the most and even basic power efficient laptops have a minimum TDP of 15W. A significant amount of that power is going to fetch actions to and from the various caches on the cpu.

Everything you just said is completely wrong.

  • Skyrim is on the switch, which is Arm based.

  • Basically every modern SoC has a ton of cache, L1/2/3. The A14 in my phone has 192+128KB L1 per Firestone core, and 8MB L2 shared.

  • “Render the simulation”? This is a video game we’re talking about here, not folding@home. All phones have had some kind of 3D GPU for over a decade now. The ones in flagships now already far exceed 360/PS3.

  • Phones still reach high performance levels despite their power limits.
