Is cortex same as Snapdragon?

The Qualcomm Snapdragon 435 (SD435) is a lower mainstream SoC for (Android based) smartphones and tablets. Contrary to the Snapdragon 630, it is still manufactured in a 28-nm process and also consists of an octa-core CPU part with ARM Cortex-A53 cores. However, they are only clocked at up to 1.4 GHz.

Is MediaTek Helio better than Snapdragon?

According to our estimates, Snapdragon is a more powerful and reliable chipset than MediaTek, but MediaTek is therefore a much more cost-efficient variant.

Is cortex better than Snapdragon?

Which is faster Kryo or cortex?

Based on these initial tests, Qualcomm’s new Kryo CPU performs better than ARM’s Cortex-A57, but slower than Apple’s Twister.

Which is best Helio processor?

MediaTek’s Helio G Series is their Gaming Series and currently has the 2nd most powerful MediaTek SOCs after Dimensity….Helio G Series.

Processor Name	Helio G90T
GPU	ARM Mali-G76 3EEMC4 at 800 MHz
Fabrication Process	12nm FinFET
CPU	2x Cortex-A76 at 2.05GHz + 6x Cortex-A55 at 2.0 GHz
