Exynos processors are divided into generations:
Exynos 3 - single and quad, based on the core ARM Cortex-A8 and ARM Cortex-A7 with a frequency of 0.8-1.4 GHz.
Exynos 4 - double and quad, based on the ARM Cortex-A9 cores with frequencies from 1.2 to 1.6 GHz.
Exynos 5 - two-, six- and quad, cores based on ARM Cortex-A15, frequency up to 2.1 GHz.
Exynos 5 Dual - includes two core ARM Cortex-A15.
Exynos 5 Hexa - contains two core ARM Cortex-A15 and four cores ARM Cortex-A7 on the principle of ARM big.LITTLE.
Exynos 5 Octa - contains four core ARM Cortex-A15 and four cores ARM Cortex-A7 on the principle of ARM big.LITTLE.
Exynos 7 Octa - contains four core ARM Cortex-A57 (ARM Cortex-A72) and quad-core ARM Cortex-A53 on the basis of ARM big.LITTLE.
The new development Samsung Exynos 8890 - representative of the eighth generation of its own chipsets Korean company, which is used as the base of the flagship smartphone line S - Galaxy S7 and S7 Edge, and can also be used in the later products like Galaxy Note 6 and hypothetical Galaxy S7 Edge +. Own M1 Mongoose core of Samsung's support ARM v8 processor architecture, which provides support for 64-bit computing. If to compare Samsung new development with existing Exynos 7420, the M1 Mongoose is far superior to it in a single-threaded computing. Exynos 8890-based M1 Mongoose was a popular benchmarke Geekbench 3 2200 points for single-threaded test, which is 45% better result Exynos 7420 (1495 points).
