S24 Exynos or Snapdragon?

Initially i was going for s24 ultra but it felt too big. Settling for s24 base model instead. So in my country, both Exynos and Snapdragon variants are available, would be buying it offline and on the box itself there is no mention of the specs. How to determine if it is an Exynos or Snapdragon variant without opening the sealed box?
