Snapdragon 4s Gen 2 announced – Qualcomm’s new affordable 5G chipset | Infinium-tech
Qualcomm has formally announced its new Snapdragon 4s Gen 2 chipset (SM4635) at an event held in India. This is not a successor to last year’s Snapdragon 4 Gen 2 but a more affordable 5G chipset based on the 4nm process and is targeted at budget smartphones, especially devices launching in India in the coming months.
At its core, the Snapdragon 4s Generation 2 has 2x Cortex-A78 cores clocked at 2.0GHz and 6x Cortex-A55 cores clocked at 1.8GHz. All eight cores are downclocked by 200MHz compared to the SD 4 Generation 2. The new chip also has an unspecified Adreno GPU, slower LPDDR4x RAM and retains UFS 3.1 storage support.
