Qualcomm Snapdragon 4 Gen 4 vs Qualcomm Snapdragon 4 Gen 2: Full Comparison
Introduction
Understanding the differences between successive generations of mobile processors can help clarify what to expect from devices in the budget and mid-range segments. This comparison examines the Qualcomm Snapdragon 4 Gen 4 and the Snapdragon 4 Gen 2, detailing their specifications, performance characteristics, and feature sets. By analyzing aspects like CPU design, GPU capabilities, connectivity, and multimedia support, this article aims to provide a clear picture of the technological evolution between these two platforms.
Performance and CPU Architecture
The core architecture and manufacturing process represent a fundamental leap between these two chipsets.
- Snapdragon 4 Gen 2: Built on a 4nm process, it typically features an octa-core CPU with two performance cores (Cortex-A78) and six efficiency cores (Cortex-A55).
- Snapdragon 4 Gen 4: Manufactured on a more advanced 4nm process (or newer node variant), it introduces a “2+6” CPU configuration, but with upgraded cores. It often pairs newer Cortex-A78 or A76-derived performance cores with Cortex-A55 efficiency cores, offering higher clock speeds for improved performance.
The newer Gen 4 chip generally provides better CPU performance and improved power efficiency due to its architectural refinements and potentially optimized process node.
Graphics and Gaming (GPU)
Graphics performance sees an incremental upgrade, affecting gaming and visual fluidity.
- Snapdragon 4 Gen 2: Utilizes an Adreno 613 GPU. This GPU handles casual gaming and standard UI graphics adequately for its segment.
- Snapdragon 4 Gen 4: Expected to feature an Adreno 619 GPU or a similar successor. This represents a step up in graphical compute power, which can translate to smoother gameplay at moderate settings and better support for higher refresh rate displays.
Camera and Multimedia Capabilities
Both platforms support capable imaging systems, but the newer generation expands on certain features.
- Image Signal Processor (ISP): The Snapdragon 4 Gen 2’s Spectra ISP typically supports single cameras up to 108MP or dual 16MP+16MP setups. The Snapdragon 4 Gen 4’s ISP is enhanced, generally supporting higher-resolution single sensors (e.g., 108MP+), faster multi-frame processing, and improved AI-based camera features like noise reduction and autofocus.
- Video & Display: The Gen 2 supports FHD+ displays at 120Hz refresh rates and video capture up to 1080p at 60FPS or 720p at 120FPS. The Gen 4 often supports FHD+ displays at 120Hz+ and can typically handle 1080p video recording at higher frame rates, along with better HDR support.
Connectivity and Modem
Connectivity is a key area of improvement, focusing on speed and efficiency.
- Modem: The Snapdragon 4 Gen 2 integrates the Snapdragon X61 5G modem, supporting sub-6GHz 5G. The Snapdragon 4 Gen 4 upgrades to the Snapdragon X65 5G modem (or a similar integrated variant), which offers improved 5G speeds, better power efficiency, and broader network compatibility in most regions.
- Other Connectivity: Both support Wi-Fi 5 and Bluetooth 5.1, though the Gen 4 may include support for newer standards like Wi-Fi 6E and Bluetooth 5.3 in some implementations, providing faster local connectivity and lower latency.
