No other relevant manufacturer has worse performance than Google
Qualcomm, i believe, currently designs the 4, 7, and 8 series SoCs for phones with each step up having more compute.
Samsung's brand new Exynos 1680 inside of the A57 is described as mid tier (source) It's a similar price to a pixel 10.
Qualcomm's snapdragon 7s gen 4 is described as unparalleled performance. (source)
That's not too definitive so I looked up the "7 gen 3" which is "premium performance" but honestly I think it's mid. (source)
The pixel 10 beats the afformentioned premium and mid tier according to these benchmarks (source)
but it loses to the Samsung S25 FE

AnTuTu: 3%-17% better
