Helio X20 MT6797 and Helio X25 MT6797T are MediaTek’s new power babies. They’ve been long awaited and have finally arrived, with the MT6797 Helio X20 scoring a huge 95k on Antutu.

What’s the difference between Helio X20 and Helio X25 / MT6797 vs MT6797T

MTK6797 and MTK6797T are very similar SoCs, but with different clock speeds set for the GPU and CPU. In all other things they’re the same. Memory RAM bus speed, encoding and decoding of video, display support, modem / RF support, and WiFi/GPS/Bluetooth connectivity are all identical.

Helio X20 vs Helio X25 comes down to just two things, the clock speeds of the Helio X20 / X25 CPU cores and the clock speeds of the Helio X20 / Helio X25 GPU cores.

We’ve also included the Helio P10 MT6755 vs MT6757 Helio P20 and the Helio X10 MT6795.
