A high-performance premium processor with a high level of energy efficiency is the Exynos 7420. This chip was introduced at the beginning of 2015 at the same time as the launch of the flagship S6 smartphone from Samsung. This chip continues to be relevant, and mobile devices based on it even today can solve any problems.
Architectural Parameters
Exynos 7420 includes two clusters. Each of these clusters includes 4 computing cores. One of them is based on the architecture codenamed “Cortex-A53” and is focused on solving the simplest problems and has very low power consumption. The maximum clock frequency for this part of the CPU is 1.5 GHz. The second cluster consists of 4 high-performance modules of the Cortex-A57 architecture with a frequency of 2.1 GHz. When it is turned on, the power consumption of the computing system increases and can reach 6 watts. Another importance of this processor device is a technological process that complies with 14 nm standards. At the moment, it is quite difficult to surprise anyone with this value, but at the time of the release of the semiconductor solution in question, this was a serious achievement. Most competing products were manufactured at 20 nm. It was this moment that ensured lower power consumption for this Samsung processor model.
RAM
The Exynos 7420 processor was aimed at using advanced, even by today's standards, LPDDR4 standard memory, the maximum amount of which can reach 4 GB in that case. The clock frequency of the memory chips in this case should be equal to 1552 MHz. In addition to this, the RAM controller in this case is two-channel, and such an engineering solution with the intensive use of random access memory allows you to achieve a 15 percent increase in performance.
Communication list
All current connection methods are supported by Samsung Exynos 7420. This list contains the following wired interfaces:
The micro-USB format port allows you to solve two problems at once. One of them is charging the battery, and the second is the exchange of information using an interface cord with a personal computer.
A 3.5 mm audio jack allows you to connect an external sound system to your smartphone.
The previous list is complemented by wireless methods for obtaining information:
Declared support for all existing cellular networks up to 4 G / LTE. The speed of connection to the global web can reach 150 Mbps.
The second important interface is Wi-Fi. In this case, data will be transmitted at speeds up to 100 Mbit / s.
Without fail, the chip in question is equipped with a Bluetooth transmitter. Its presence allows you to output sound to a wireless stereo headset or to exchange small files with similar mobile phones.
The GPS sensor, which is universal and can successfully interact with any modern navigation system, complements this list.
Graphics subsystem
Exynos 7420 also has an integrated graphics system based on the Mali T760 MP8 accelerator. This accelerator includes 8 graphic information processing units and can operate at frequencies from 700 to 772 MHz. The specified technical characteristics allow this adapter to process the output image in 2K or 2560x1440 format.
Owners opinion
Only in the most productive smartphones can you find the Samsung Exynos 7420. The previously mentioned technical specifications additionally emphasize the premium status of this processor solution. The list of smartphones with this CPU contains S6, S6 EDGE and Note 5 from Samsung and PRO 5 from Meizu. For all these devices, the following advantages can be distinguished based on the feedback of the owners:
High level of performance that allows you to solve any problem.
Excellent chip energy efficiency through the use of the most advanced semiconductor chip manufacturing technology.
The smooth operation of the graphics accelerator.
The minus in this case is only one - the high cost of mobile gadgets. But the flagship smartphone, which is based on the Samsung Exynos 7420 processor, by default may not be available.
Summary
Still often on sale you can find mobile devices based on the Exynos 7420. Their advantages include performance and energy efficiency. And the disadvantage of high cost is a typical problem of any modern premium-class smartphone.
