Samsung Exynos 7420 vs Qualcomm Snapdragon 805 – specs, performance and benchmark results

We are still testing the new Samsung Galaxy S6 and you can expect our detailed review as soon as we complete all of the tests we’ve prepared. Get ready for some very interesting details which you can’t find anywhere else.


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?
