Qualcomm Snapdragon 4 Gen 2 vs Qualcomm Snapdragon 4 Gen 1: Full Comparison
Introduction
When evaluating entry-level and budget-friendly mobile devices, the chipset plays a crucial role in defining the user experience. The Qualcomm Snapdragon 4 series is designed for this segment, balancing cost with essential performance. This comparison examines the differences between the Snapdragon 4 Gen 1 and its successor, the Snapdragon 4 Gen 2. Understanding the evolution between these two platforms can help clarify what improvements are generally expected in areas like efficiency, photography, and connectivity in newer devices.
Performance and Efficiency
The core architectural differences between these two chipsets are significant for overall system responsiveness and battery life.
- Manufacturing Process: The Snapdragon 4 Gen 1 is built on a 6nm process. The Snapdragon 4 Gen 2 moves to a more advanced 4nm process, which typically allows for better power efficiency and can reduce heat generation.
- CPU Configuration: Both chipsets feature an octa-core CPU. However, the Gen 2 introduces a newer CPU architecture (Cortex-A78 performance cores and Cortex-A55 efficiency cores) compared to the Gen 1’s older Cortex-A78 and Cortex-A55 mix. This architectural update in the Gen 2 generally provides a performance uplift for the same clock speeds.
- GPU: Both integrate an Adreno GPU. While the Adreno GPU in the Gen 2 is a newer iteration, real-world gaming performance in this segment is often similar, focused on casual and light gaming titles.
Camera and Imaging
The image signal processor (ISP) is a key differentiator, affecting camera capabilities in devices using these chipsets.
- ISP: The Snapdragon 4 Gen 1 features a Qualcomm Spectra ISP. The Snapdragon 4 Gen 2 upgrades to a newer Spectra ISP, which adds support for higher-resolution sensors.
- Camera Support: A notable upgrade in the Gen 2 is its support for a single camera of up to 108MP, a significant jump from the 32MP maximum single-camera support in the Gen 1. This allows device manufacturers to include higher-megapixel main cameras in budget phones.
- Features: Both support standard features like multi-frame noise reduction and electronic image stabilization (EIS) for video, with the Gen 2’s newer ISP potentially offering more refined processing.
Connectivity and Charging
Modern connectivity standards and charging speeds are important aspects of the user experience.
- Modem: Both platforms integrate a 4G LTE modem, as the Snapdragon 4 series does not include 5G connectivity. The Snapdragon 4 Gen 2’s modem is a newer version, which may offer marginally better reception or efficiency in some scenarios.
- Wi-Fi & Bluetooth: The Gen 1 supports Wi-Fi 5 and Bluetooth 5.2. The Gen 2 upgrades to support for Wi-Fi 5 (802.11ac) and the newer Bluetooth 5.3 standard, which can improve connection stability and power efficiency for audio devices.
- Charging: A clear advancement in the Gen 2 is its support for Quick Charge 4+ technology, enabling faster wired charging speeds compared to the Quick Charge 3.0 support found in the Gen 1.
