We now have our first look at the Snapdragon 875 and Exynos 1000's Geekbench scores. The latter convincingly outperforms the former, with a single-core score of 1327 and a multi-core score of 4250. It is also worth noting that those numbers are within spitting distance of the Apple A13 Bionic.

Interesting, but without power draw numbers this is all rather theoretical. Previous Exynos SoCs have been massive power hogs, so unless they've managed to fix that too this will still throttle heavily.
It's unlikely there are even engineering samples this early in the cycle, sounds fake.
