The rating of mobile processors

 

The feature of mobile processors is their ability to operate on one battery with a minimum heating of the case. But it often happens that the chip shows a high performance but very quickly discharged the battery. Conversely, performance may be slightly lower, but it increases the energy efficiency. So to judge the superiority of one chip over another is not always true. Mobile processors are built for multi-core architecture. The presence of a larger number of cores increases the number of tasks running simultaneously, provided optimization software.

This article presents a list of mobile GPUs in order of ascending performance.

10. Intel Atom Z3775D

9. Intel Atom Z3775

Ninth place went to Quad-core processor with a frequency of 1.46-2.39 GHz Intel Atom Z3775, designed for smartphones. Optimized 22 nanometer process Р1271 with transistors tri-gate shows improved performance and energy efficiency compared to the previous Atom Z2770.

8. Intel Atom Z3785

Quad-core mobile processor for tablets and smartphones on Android and Windows , Intel Atom Z3785 took the eighth position in productivity. SoC running at a frequency of about 1.49 to 2.41 GHz, built on part of the platform Bay Trail-T. Thanks to streamlined 22-nm process in combination with tri-gate transistors have improved performance and energy savings compared to previous generation. Processor cores architecture Silvermont show the performance of 50% above, through the use of pipeline, optimization of branch prediction, the expansion of the decoders and increase the buffer.

7. Intel Atom Z3795

On the sixth processor, designed for tablets Windows and Android, Intel Atom Z3795. A Quad-core chip operates at a frequency of from 1.59 to 2.39 GHz. Optimized 22-nm processor using transistors Tri-Gate improved performance and reduced power consumption compared to the previous series Atom. Performance Z3795 designed mainly to work with the office application and browser, so for compute-intensive tasks it is not enough.

6. Qualcomm Snapdragon 808 MSM8992

Mobile processor Qualcomm Snapdragon 808 MSM8992, specially designed for tablet devices and smartphones based on Android, has 6 processor cores, graphics card Adreno 418 with 232-bit memory controller LPDDR3-1866, Bluetooth 4.1, UMTS and LTE. Based on ARM big.LITTLE that combines different processor cores for an optimal combination of performance and power, 808 MSM8992 integrates two fast Cortex-A57 clocked at 2 GHz, with productivity 30% higher than the previous processor in the series.

5. Qualcomm Snapdragon 810 MSM8994

Fast eight-core Qualcomm Snapdragon 810 MSM8994 designed for tablets and smartphones, produced by 28-nm process technology. It uses two groups of 64-bit cores Cortex-A57 and Cortex-A53. If necessary, all the cores of the Snapdragon 810 can operate simultaneously. There is a graphics accelerator Adreno 430, the controller is LPDDR4 memory, modules Wi-Fi (802.11 ac MIMO), Bluetooth 4.1, 3G and LTE. Accelerator Adreno 430 is able to cope with any games in Full HD and above.

4. Intel Atom x7-Z8700

Mobile processor Intel Atom x7-Z8700, presented in 2015, uses four computational core Cherry Trail. If you compare with earlier processors of this series, the new Intel Atom x7-Z8700 has several key advantages. Streamlined architecture and 14 nm process technology with a clock frequency of 2.4 GHz allows to achieve high performance while maintaining low dissipation. Here integrated memory controller LPDDR3-1600 and the graphics adapter HD Graphics (Cherry Trail), which supports DirectX 11.2 and utilizes 16 compute units (shaders) with a frequency in the range of 600 MHz. Atom x7-Z8700 can be used for both laptops and tablets and smartphones.

3. ARMv8 Apple A9

In third place in the list are 64-bit dual-core ARM microprocessor architecture ARMv8 Apple A9. It is made по14-nm FinFET process technology. The A9 chip, which is a 2-core SoC with 1.8 GHz, got a performance increase up to 70 % overall and 90 % on the chart compared to the previous generation of chips (Apple A8). Power consumption of the chip is reduced by 35% and decreased by 15 %.

2. Samsung Exynos 7420 Octa

In second place is the Samsung Exynos 7420 Octa. Mobile processor was introduced in 2015, with the device Samsung Galaxy S6. 7420 Octa uses eight cores according to the architecture of big.LITTLE. The overall performance is quite high and it can be compared with the Snapdragon 810 from Qualcomm or Tegra K1 from Nvidia. Production according to the norms of 14-nanometer technological process allows also to reduce power consumption on the background of earlier developments (20 nm or 28 nm). As a complete system-on-chip (SoC), Exynos 7420 Octa uses many additional components, including a graphics accelerator ARM Mali-T760 MP8, controller fast memory LPDDR4 and various communication modules.

1. Apple A9X

Apple A9X from the company Apple tops the ranking of the best mobile processors. It is made according to the process 16-nm FinFET at TSMC factories. Processor core Twister is a third generation 64-bit ARM-cores that operate at frequencies up to 2.26 GHz. Compared to the Apple A8X chip that is two times increased memory bandwidth. According to Apple, the new chip is 1.8 times better performance in office than the A8X used in particular in the iPad Air 2. Chip area estimates Chipworks is 147 mm2.
