A few hours ago, we reported that the Galaxy S5 has an Exynos Octa-core flavour too. We knew that Samsung will announce these Exynos flavour very soon and we were right. The newly announced Samsung Exynos 5422 Octa has 4 Cortex-A15 cores @ running at 2.1 GHz each and 4 Cortex-A7 cores ticking at @1.5 GHz.
The Samsung Exynos 5260 hexa on the other hand has a combination of 2 Cortex-A15 cores (at 1.7 GHz each) and 4 Cortex-A7 running at 1.3 GHz each.
Both these Exynos chipsets employ ARM’s big.LITTLE processing and Samsung’s own HMP (Heterogeneous Multi Processing). Powered by these technologies the CPU can use all 8 cores simultaneously if needed and remain highly power efficient during periods of low load.
They haven’t disclosed the GPU but we guess it that it belongs to Mali-T6xx series. These chipsets also support display resolution of upto 2650×1600 pixels (WQXGA). The Exynos 5422 is also capable of encoding/decoding 4K video playback. The Exynos 5260 can encode/decode 60fps full-HD videos .
The Exynos 5422 looks good on paper but we’ll know how well it performs when we compare devices running on it with those running on MediaTek MT6595 and Snapdragon 615.
