This new Apple TV 4K should have used an A12X Bionic and not the A12, as the A12X Bionic is the true successor to the A10X Fusion (see 2017 iPad Pro and 2018 iPad Pro). The A12 is barely toe to toe with the A10X, synthetic benchmarks aside. A12, first seen on the iPhone XS and XS Max pale in comparison to the iPad Pro with the A12X and even the iPad Pro with A10X. This is repeated again with the 3rd Gen iPad Air from 2019. It borrows several things form the 10.5" iPad Pro, such as the shell, smart connector, Smart Keyboard, but misses out in performance even with a newer SoC. A 2018 iPad Pro is the true successor to the 2017 iPad Pro, not the 2019 iPad Air. Likewise, the successor to the 2017 Apple TV 4K with an A10X should've been an Apple TV 4K with an A12X.
Remote aside, you get the same shell, but you do get AX wifi among some other gimmicks, however I'm not 100% sold on whether performance would be significantly better, especially as they're advertising Apple Arcade which at times struggled in the the previous Gen and history has shown the A12 to not be that significant outside of the iPhone XS.
[This is from my experience as someone who has the 2017 iPad Pro, 2x 2018 iPad Pro, 2019 iPad Air, 2018 iPhone XS Max, for comparison. A10X outperformed the A12 in the iPad Air when it came to scrubbing 4k H.265/HEVC video as well as exporting and playback on LumaFusion. Likewise, the A12X smoked the A10X with the same 4k H.265/HEVC video. Games such as CoD mobile also performed better on both iPad Pros vs the iPad Air and iPhone XS Max.] Synthetic benchmarks like Geekbench show mild improvements in terms of the A12 over the A10X, and significant improvements form the A12X over both, however that's just specs on paper.
To me, it doesn't seem very promising that the new Apple TV will prove to be a substantial improvement over it's predecessor.
