Samsung Exynos 7420 review: 18 facts and highlights

1. total clock speed

4 x 2.1GHz & 4 x 1.5GHz
MediaTek Helio X30: 2 x 2.6 & 4 x 2.2 & 4 x 1.9GHz

2. Has integrated LTE

The system on a chip (SoC) has an integrated LTE cellular chip. LTE is capable of downloading at faster speeds than older, 3G technology.

4. semiconductor size

A smaller size indicates that the process to create the chip is newer.
14nm
Qualcomm Snapdragon 710: 10nm

5. RAM speed

It can support faster memory, which will give quicker system performance.
1552MHz
Intel Core i7-8700B: 2666MHz

6. Uses big.LITTLE technology

Using big.LITTLE technology, a chip can switch between two sets of processor cores in order to maximise performance and battery life. For example, when playing a game the more powerful cores will be used to increase performance, whereas checking email will use the less powerful cores to maximise battery life.
