Verdict: Galaxy S24 ahead on 3 rows, Galaxy S23 on none
On the makers’ figures and the named third-party sources, the Galaxy S24 wins on peak brightness (2,600 nits against 1,750 nits), claimed video playback (29 h against 22 h) and Geekbench 6 (CPU, multi-core) (5,965 against 4,547, both from Geekbench Browser). The differences in weight, display size and battery capacity are below the thresholds you would notice. Both state the same refresh rate, storage (base), RAM, fast charging and wireless charging. The other 32 rows have no threshold or no direction to judge by, so nobody wins them.

Specifications
A win is marked only where the figures can be ranked and the gap is one you could notice. A row the site has no threshold for says whether the two differ, and that it is not ranking them. = marks the same figure on both, ≠ not ranked a difference with no ranking. Every figure carries its source.
