Samsung uses a variety of platforms in its smartphones, ranging from Unisoc to Qualcomm. MediaTek chips are also used, although quite rarely recently. According to insider Revegnus, MediaTek offered the Korean giant special prices for its platforms.
This is a special discount for Samsung, but it is unknown how big it is. There is also no data whether it applies to all MediaTek SoCs or to some specific ones.
One might assume that MediaTek in this way wants to try to lure Samsung to its top-end Dimensity platforms, but it is far from certain that the company has precisely such goals. At a minimum, Samsung has already signed an agreement with Qualcomm, so it is unlikely that we will see Galaxy S smartphones based on SoC Dimensity 9xxx in the next couple of years.
In any case, it is likely that in the near future there will be more Samsung smartphones based on the MediaTek SoC.
Insider Revegnus was the first to publish a photo of the Samsung Galaxy Z Flip5 before its release, reported on the AMD GPU in the Exynos 1480 SoC, and also described the characteristics of the Exynos 2400, which were then confirmed in Geekbench software.
