Samsung has consistently manufactured their Galaxy S series in two different versions -- a Qualcomm one, and an Exynos one (Samsung's in-house CPU division), with different geographic markets getting different options. America has always gotten the Qualcomm version (which has consistently been faster), but other markets have seen shifts over time.
The S23 Ultra went Qualcomm-only for the first time. In the year running up, they've been slowly expanding Qualcomm to more markets instead of Exynos.
It seems like they're gradually phasing out Exynos, at least from the higher-end phones -- since they've always struggled to produce an SoC competitive with even Qualcomm, which is already behind the curve compared to Apple.
