The Galaxy S20 Ultra has two versions, one with traditional LTE and another with 5G internet compatibility. Because of that, it comes with two processor options. The version has Exynos 990 (octa-core up to 2.7 GHz) and supports only fourth-generation networks in Brazil and some countries, and there is another model available in the USA and other countries. In this case, the mobile comes with Snapdragon 865 (octa-core up to 2.8 GHz).

AnTuTu’s latest ranking showed that Qualcomm’s processor does better in testing. The difference in the chip was the subject of a petition from customers asking the South Korean giant to stop using Exynos line processors on the brand’s smartphones.
