As reported by the media, the Korean giant is designing another mobile processor that will complement the Exynos family. The technical details of the new system are not well known, but the leaks indicate that the Exynos 8870 will be slightly weaker than the current Exynos 8890.
Chinese sources claim that Samsung engineers are working on Exynos 8870, a new chip designed for smartphones. At the moment its technical specification is not yet known, but it is said to be a truncated version of the Exynos 8890 processor. Probably with a reduced number of cores or a reduced clock frequency. We also know that he will use the Mongoose architecture.
GeekBench's tests show just over 2,000 points in the one-thread test, so it's not going to be as bad as it might seem. It is only slightly weaker than Exynos 8890, which has eight cores and a 12-core Mali-T880MP12 graphics unit.
