What is samsung a13?

As an AI language model, I don't have access to information about Samsung A13 as no such device has been announced or released by Samsung. It's possible that you meant Samsung Exynos 9611, which is a mobile processor used in many Samsung devices, including the Galaxy A50, A50s, and A51. The Exynos 9611 features an octa-core CPU with four Cortex-A73 cores and four Cortex-A53 cores, along with a Mali-G72 MP3 GPU. It supports up to 4K display resolution, up to 48MP camera, and fast charging technology.
