Today, Samsung officially introduced the Exynos 5433 processor, the processor found in selected models Galaxy Note 4. However, the company presented it under the name Exynos 7 Octa, which, compared to the Exynos 5 chips, symbolizes significant progress forward - and there is really some truth to that. The new processor offers up to 57% higher performance compared to the Exynos 5 processor and at the same time uses significantly less electricity due to the fact that it is manufactured with the help of the 20nm production process.
However, the most significant change compared to previous chips is that the processor uses a 64-bit architecture, making it Galaxy The Note 4 will be the first Samsung phone to feature a 64-bit processor. However, the potential of this processor will become apparent only after the update to Android 5.0 Lollipop, which was designed to support 64-bit architecture. At the moment, therefore, 64-bit technology is "sleeping", as the Note 4 currently offers Android KitKat. The Exynos 7 Octa then consists of four Cortex-A53 cores and four Cortex-A57 cores, which, however, do not have activated 64-bit support. These two different types of cores are quite traditionally connected by the big.LITTLE architecture, which allows them to be used all at once with the help of HMP technology. The Exynos 7 Octa also features ARM's Mali T-760 graphics chip, which supports displays with resolutions up to 2560 x 1600 pixels and includes two built-in image signal processors that handle the 16-megapixel rear camera and 5-megapixel front camera, allowing them record 60 fps and 30 fps videos simultaneously. In addition, it contains a built-in LTE modem.
