It seems both Samsung's and Qualcomm's custom processor cores turned out for the better and we like where things are going. That's not that a big gap and nobody will be able to tell the difference in real life. The Qualcomm's Kryo (2.15GHz) core inside the Snapdragon 820 in the Xiaomi Mi 5 and the S820 model of the Galaxy S7 edge turned out the better though - about 7% faster than the Mongoose. The 2.6GHz clocked custom Mongoose CPU core turned out a great performer - about 30% faster than the Cortex-A57 inside the S6 edge+. Half a gig is available to the GPU, while the rest 3.5GB are handled by the OS. Whatever flavor of the S7 edge you get, 4GB of LPDDR4 RAM will be available at your disposal. The GPU in charge of graphics is the most powerful Qualcomm Adreno model - the Adreno 530. In case you get the Snapdragon 820 model of the Galaxy S7 edge - this means you will be getting a quad-core processor with custom high-performance Kryo cores (2x 2.15GHz, 2x 1.6GHz). The GPU inside the Exynos 8890 is the most powerful ARM Mali to date - the Mali-T880 MP12, which means it has 12 processing cores. We suspect the clock limitation is due to thermal restrictions. Oddly, only two of the Mongoose cores can run at the maximum of 2.6GHz, if you need all of them - they can go as high as 2.3GHz. The eight-core processor of the Exynos 8890 has four Mongoose cores ticking at 2.6 GHz and four (low-power) Cortex-A53 running at 1.59 GHz. The Exynos 8890 chipset is Samsung's first silicon to come with custom high-performance CPU cores called Mongoose. We were able to find the Snapdragon 820 flavor so you can see how those two compare in performance. Selected markets will be getting Snapdragon 820-based units. The Samsung Galaxy S7 edge unit we got is the global version, powered by the Exynos 8890 chipset. Still, since we like being thorough, we've added the test scores on Nougat firmware as separate entries. We've also re-run the full set of benchmarks and the deviations, where present, are mostly marginal. Update (): The Android 7.0 Nougat update for the Galaxy S7 edge is here and we've covered the differences in-depth in a dedicated article.
