Samsung is working on releasing an Exynos 8870 chipset, which is going to be less powerful than its top-of-the-line Exynos 8890. The Exynos 8870 will be made specifically for Samsung's external clients like Meizu.
In fact, rumor has it the Meizu Pro 6 might use the chipset when it gets to market some time next year. Expected performance of the new chipset is along the lines of the Qualcomm Snapdragon 820, so we'd imagine it's not slow by any means.
Details on the architecture of the chipset are nonexistent at the moment. We suspect more information will become available as Samsung starts testing the Exynos 8870 and it pops up in some benchmarks' database.
Meanwhile MyDrivers.com compiled a nice chart comparing the major flagship chipsets for the start of 2016. The graph shows the performance of the Samsung Exynos 8890, Qualcomm Snapdragon 820, Kirin 950, Helio X20 and Apple A9 as benchmarked by GFXBench for GPU performance and Geekbench 3 for CPU stress testing.
In the CPU performance chart, the Apple A9 chip is leading in single-core performance with 2546 points, followed by the Snapdragon 820. The Exynos 8890 and Helio X20 follow closely. In multicore testing, however, the picture is quite different and the Exynos 8890 leads, followed by the Helio X20 and Kirin 950.
As far as GPU performance is concerned, the Snapdragon 820's Adreno 530 GPU leads, while the Exynos 8890's Mali-T880 GPU is second. Apple's A9 GPU is third, as the Helio X20 and Kirin 950 fail to deliver comparable performance.
as you can see, you buy a phone because it will serve you as a phone mainly. you are not buying the phone to run heavy task, even if you do you will feel it is not that much of your everyday work. how do you feel when you hold a slow heavy phone that...
You missed my favourite Kirin 950!
