Samsung does not design customized processors!
During the periods when Apple and Qualcomm were at the top of the customized mobile processor core race, Samsung also turned to core designs called Mongoose and used it in 5th generation Exynos processors.
However, efficiency issues caught on, and he had to revert to standard ARM designs. Some claims were that customized cores would be used in Exynos processors that will reach 2025. However, Samsung denied this.
The company announced that they hired engineers to the Exynos division when necessary, but they do not have any customized core plans. In other words, any architecture such as Cortex-X3 or X4 will be used at that time. It is speculated that Samsung will make a change to the Galaxy S25 series at the earliest. On the other hand, it is not yet known how the integrated Radeon graphics units with ray tracing will progress.
