The geekbench scores of Apple are highest and then Qualcomm according to this page. MediaTek’s top chip is literally 25% slower according to his listing.

The ordering in ranking is a little weird.

25% slower than apple is more than enough for a mobile chip. The new apple chips are faster than desktop chips from a few years ago

You got even that wrong. Single-core GB score is highest, multicore is not. Snapdragon's score is higher.

People do not seem to understand that these chips are in different price brackets, even between Qualcomm and Mediatek. That is why there is a discrepancy in performance.

Would not be fair to compare a $20 toaster to a $50 toaster and say that the $20 toaster is slower.

I never thought I would hear MediaTek and top chip maker in the same line
