Qualcomm 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 fabbed on a 4nm process and aimed at budget smartphones, specifically devices launching in India in the coming months.
At its core the Snapdragon 4s Gen 2 features 2x Cortex-A78 cores clocked at 2.0GHz and 6x Crotex-A55 at 1.8GHz. All eight cores are downclocked by 200 MHz compared to the ones on the SD 4 Gen 2. The new chip also gets an unspecified Adreno GPU, slower LPDDR4x RAM and retains UFS 3.1 storage support.
