Snapdragon 4s Gen 2 details leak: lower clock speeds, slower 5G modem

Qualcomm will announce a budget 5G chipset at tomorrow’s ‘Snapdragon for India’ event and Evan Blass may have just spoiled the surprise – here are the details for the Snapdragon 4s Gen 2. This is a lower power, cheaper version of the Snapdragon 4 Gen 2 from last year.

This is still a 4nm chip with an octa-core CPU (two Cortex-A78 plus six A55), but with the clock speeds dialed back by 200MHz. The GPU presumably took a step back as well. Also, only 2,133MHz LPDDR4X RAM is supported (the non-s model can also use 5X at 3,200MHz). In terms of performance, this should slot in somewhere between the original Snapdragon 4 Gen 1 and the 4 Gen 2, but it should have better efficiency than the Gen 1 chip.

Another noticeable change is that the display support is down to 90Hz refresh rate at FHD+ resolution. This is aimed at cheaper phones, so they will either use HD+ displays at 120Hz or FHD+ at 90Hz. The dual ISP can no longer support 108MP image sensors too, so manufacturers will likely settle at 50MP or 64MP.

This is an affordable 5G chipset, but its 5G capabilities have been scaled back compared to the 4 Gen 2 and the downlink speed is limited to 1Gbps (down from 2.5Gbps). Whether there is a tangible difference in daily use is another matter. Local connectivity is relatively limited with support for the older Wi-Fi 5 (ac) and Bluetooth 5.1 standards, but the same applies to the 4 Gen 2 (these are 4-series chips, after all).

The chip still features the Qualcomm Audio and Voice Communication suite and can stream music at 96kHz. It has multi-frame noise reduction and EIS for the camera, plus dual-frequency reception for global positioning.

Snapdragon 4s Gen 2 (QCTSD4SG2) leaked details

Check back tomorrow to see if Qualcomm officially confirms these details. Also, tomorrow’s event promises “two historic announcements” – one is almost certainly the Snapdragon 4s Gen 2, the other is anyone’s guess.
