The Xiaomi 13 and Xiaomi 13 Pro may well be the most high-profile smartphones to launch with the Snapdragon 8 Gen 2 so far. However, TENAA has confirmed that the Samsung Galaxy S23, Galaxy S23 Plus and Galaxy S23 Ultra will all feature the SM8550-AC, an overclocked version of the Snapdragon 8 Gen 2 offered in other flagship smartphones.https://www.notebookcheck.net/Samsung-Galaxy-S23-series-confirmed-to-launch-with-more-powerful-Snapdragon-8-Gen-2-chipset-than-Xiaomi-13-or-Xiaomi-13-Pro.674181.0.html
I believe that the overclock is 160MHZ and not the 400MHZ listed. 3.36GHZ - 3.2GHZ = 0.16GHZ which is 160MHZ.
