Qualcomm has announced the Snapdragon 7s Gen 4 mobile chipset. It's a 4nm mid-range SoC that brings few improvements over its predecessor, and is expected to be used in budget smartphones, starting with the upcoming Redmi Note series.
The Snapdragon 7s Gen 4 is a TSMC-made 4nm octa-core processor with a 1+3+4 core setup consisting of 1x Cortex-A720 clocked at 2.7 GHz, 3x Cortex-A720 at 2.4 GHz and 4x Cortex-A520 clocked at 1.8 GHz.
The GPU isn't getting a massive upgrade either, so as a result, Qualcomm is promising 7% improved performance across both the CPU and GPU. The latter is an Adreno unit with Vulkan 1.3 and OpenGL ES 3.2.
The 7s Gen 4 supports up to WFHD+ 144 Hz (1300 x 2900 pixels) displays, retains the 12-bit triple ISP and up to 4K 30 fps HDR recording. There's Qualcomm's built-in 5G modem with support for 5G mmWave and sub-6 GHz frequencies with download speeds of up to 2.9 Gbps.
The 7s Gen 4 also retains Qualcomm's Hexagon NPU, alongside FastConnect Mobile Connectivity System, Bluetooth 5.4 and Wi-Fi 6E. Storage and RAM-wise, it supports UFS 3.1 Gen 2 and up to 16 GB of LPDDR5 3200 MHz memory.
One of the first devices that could soon arrive with the Snapdragon 7s Gen 4 could be the Redmi Note 15 Pro that's launching on August 21, 2025. The series includes the Redmi Note 15 Pro and Redmi Note 15 Pro+.
The Snapdragon 7s Gen 4 brings a mild performance boost over its predecessor, and nothing major to write home about. However, Qualcomm is playing it safe with its mid-range Snapdragon formula, where manufacturers tend to offer incremental upgrades, prioritising stability, efficiency and cost-effectiveness.
