Samsung Exynos 7420
Process 14-nm-FinFET
Cores 4+4
Frequency 4 х 1.5GHz + 4 x 2.1GHz
Architecture ARM big.LITTLE – 4 х Cortex-A53 & 4 х Cortex-A57
GPU Mali-T760 MP8 / 772 MHz

Qualcomm Snapdragon 805
Process 28 nm HPm
Cores 4
Frequency 2.7 GHz
Architecture Krait 450 / 772 MHz
GPU Adreno 420

In any case, the new Exynos 7420 is one of the greatest new features in Galaxy S6. It has four Cortex-A53 cores working at 1.5 GHz and four 2.1GHz Cortex-A57 cores. The GPU is a high-end Mali-T760, which provides a superb performance. Exynos 7420 is the first SoC which uses a 14-nm-FinFET-SoC LPE (Low Power Enhanced) process. This time there is no Snapdragon version or anything of the sort, just an Exynos model. Samsung claims that, thanks to the 14-nm FinFET technology, their Exynos chip is 20% faster, 30% more powerful and 35% more energy-efficient than its 20nm predecessor. Eight powerful cores, new technology and a pinch of engineering thought. This sounds very promising.

We can see how powerful the processor is by comparing it to Qualcomm Snapdragon 805. We used Motorola Nexus 6 for this purpose. Snapdragon 805 is still one of the best mobile chips on the market. You can find it in some top devices like Galaxy Note 4, Nexus 6 and Motorola Droid Turbo. It has four Krait 450 CPU cores, working at 2.7 GHz and a great GPU – Adreno 420. Keep in mind that it’s older than Exynos 7420, so this isn’t exactly the fairest comparison. However we aren’t looking for a winner, we just want to compare to understand how powerful the processor is. Let’s start the comparison. Which one are you betting on?
