Snapdragon 4s Gen 2 details leak: lower clock speeds, slower 5G modem | Infinium-tech
Qualcomm will announce a budget 5G chipset at tomorrow’s ‘Snapdragon for India’ event and Evan Blass may have spoiled the surprise – here are the details of the Snapdragon 4s Gen 2. It is a lower-powered, cheaper version of last year’s Snapdragon 4 Gen 2.
It’s still a 4nm chip with an octa-core CPU (two Cortex-A78 plus six A55), but the clock speed is 200MHz lower. Presumably the GPU has taken 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, it should be placed somewhere between the original Snapdragon 4 Generation 1 and 4 Generation 2, but it should have better efficiency than the Generation 1 chip.
Another notable change is that display support has dropped to a 90Hz refresh rate at FHD+ resolution. This is for cheaper phones, so they will either use HD+ displays at 120Hz or FHD+ at 90Hz. Dual ISP can no longer support 108MP image sensors either, so manufacturers will likely settle for 50MP or 64MP.

| Video | Up to 1080p @ 60fps | Up to 1080p @ 60fps, EIS | Up to 1080p @ 60fps |
| Modem | X51 (download 2.5Gpbs, up to 800Mbps) | X61 (Release 16, 2.5Gpbs down, 900Mbps up) | Down to 1Gbps |
| local | Wi-Fi 5, Bluetooth 5.1 (aptX) | Wi-Fi 5, Bluetooth 5.1 (aptX) | Wi-Fi 5, Bluetooth 5.1 (aptX) |
| USB | 3.2 Gen 1 | 3.2 Gen 1 | 3.2 Gen 1 |
| Charge | Quick Charge 4+ | Quick Charge 4+ | Quick Charge 4+ |
This is an affordable 5G chipset, but its 5G capabilities are toned down compared to the 4th Generation 2 and downlink speeds are limited to 1Gbps (down from 2.5Gbps). Whether there’s 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 4th Generation 2 as well (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, as well as dual-frequency reception for global positioning.
Snapdragon 4s Gen 2 (QCTSD4SG2) details leaked
Check back tomorrow to see if Qualcomm officially confirms these details. Also, tomorrow’s event promises to have “two historic announcements” – one is almost certainly the Snapdragon 4s Gen 2, the other is anyone’s guess.
