That is interesting because i would have expected they will be using DLSS a LOT for keep the gpu power down. But for games you do need two strong cores... there is no way around it. Specially for the games that will be ported over. (like everything thats not a Nintendo game)
Most of the minimum specs for mobile games are throttle phones. Which have a 32-bit memory bus, 4x Cortex A73 @ 1.8 GHz, 64~128 ALU iGPU @ 600 MHz.
There is several big IPs on Switch 1. With no major issues. The side that is actually critical for handhelds is just the GPU and memory speed.
Crysis Trilogy, Warframe, DC Universe Online, Palia, Ace Combat 7, No Man's Sky, etc. On a Cortex-A57 @ ~1 GHz and Maxwell @ 307.2 MHz. Hacked (lineage os) Switch 1.0 w/o overclocking (stuck in handheld mode) can run lowest setting of Genshin and Wuthering Waves.
Switch 1: 4x Cortex-A57 @ ~1 GHz + 2x Maxwell 2.0 SMs @ ~0.3 GHz, ~25.6 GB/s
Switch 2: 8x Cortex-A78 @ ~1 GHz + 12x Ampere SMs @ ~0.56 GHz, ~68 GB/s
It isn't going to be that big of a deal. Isn't the effective instruction-level parallelism boost equivalent to...
8x Cortex-A57 @ ~4+ GHz
8x Cortex-A72/A73 @ ~2.1+ GHz
I am pretty sure the data for overkill phones running at 30 fps/60 Hz rr or 60 fps/90 Hz rr. The cores would not be running at the max clocks stated.
Snapdragon 8 Gen 1 (Genshin Impact) at sub-5w SoC = 1x 1.2 GHz(X2) + 3x 1.2 GHz(A710) + 4x 1.1 GHz (A510), seems to be the average. That is the average, for it to be that low means significant time is actually spent below 900 MHz. I went back even further to Unisoc T612, the fastest core rapidly fluctuates between 700 MHz to 1500 MHz on Zenless Zone Zero. However, it could be held back by the Mali-G57 MP1. I don't think people realize how little is needed to run these games. Even an Exynos 850 (just Cortex-A55) can play Genshin && Wuthering Waves. However, good luck with that <10 fps.
