With the Galaxy S line, Exynos is back after a year away. It was reported a month ago that all Galaxy S25 phones would use Exynos everywhere – this was just the first step to complete dominance. According to a post by DigiTimes today, that is not true.
According to the report, Samsung will continue to use both Qualcomm and Samsung chipsets – the Snapdragon 8 Gen 4 and Exynos 2500 in this case.
There is no information about where the dividing line will be drawn in the information. The Galaxy S25 Ultra is expected to use the Snapdragon exclusively, while the Galaxy S25 and S25+ will be either Snapdragon or Exynos, depending on where you buy them.
One report claimed that the Galaxy Z foldable series would only use Snapdragon chips, but another suggested that it might use Exynos 2400. In that case, it would be the first foldable to use an Exynos chip. As for the Z Flip6, Z Fold6 (and possible Ultra and FE models), we will know soon enough.
The Exynos 2500 will certainly power the Galaxy S25 and S25+, if Samsung has enough faith in it to use it in its pricey flip foldable (which is small and hard to cool).
As compared to the 2400, the Exynos 2500 should provide further optimizations and improved power efficiency. The S25 series will also undergo other changes.
