The Snapdragon 835, commonly known as the Qualcomm Snapdragon processor, was introduced in early 2017 to support Quick Charge 4.0 fast charging technology. This chip marked a significant step forward in mobile processing power and energy efficiency.
**Process**
Built on Samsung’s 10nm manufacturing process, the Snapdragon 835 offered substantial improvements over its 14nm predecessors. The 10nm process allowed for a 27% increase in speed and a 40% improvement in efficiency. Additionally, the chip's smaller size enabled more space for larger batteries or thinner designs in smartphones.
In October 2016, Samsung announced that it had successfully mass-produced the 10nm FinFET process, which reduces power consumption by up to 30% compared to the 14nm process. This advancement, combined with improved chip design, contributed to longer battery life in devices using the Snapdragon 835.
**Core**
The Snapdragon 835 features an eight-core architecture, including two high-performance Kryo 280 cores running at 2.45GHz and six efficient Kryo 280 cores at 1.9GHz. It also includes the Adreno 540 GPU, operating at 670MHz, which delivers a 25% performance boost over its predecessor. The chip supports 4K displays, UFS 2.1 storage, dual camera setups, and LPDDR4x memory with four channels. It also integrates a Cat.16 baseband for faster connectivity.
**Fast Charging**
With support for Quick Charge 4.0, the Snapdragon 835 offers 20% faster charging and 30% greater efficiency than Quick Charge 3.0. A 5-minute charge can extend device usage by up to 5 hours. It also supports USB-C and USB-PD for broader compatibility.
**Efficiency Improvement**
Although Qualcomm did not provide detailed specs, the 10nm process is expected to deliver better performance and power efficiency compared to the 14nm-based Snapdragon 820. Samsung claimed that the 10nm process could make chips 27% faster and 40% more efficient.
**Memory Bandwidth**
The Snapdragon 835 was the first to support LPDDR4x, offering faster data transfer rates and significant bandwidth improvements over LPDDR4.
**Kirin 970 Overview**
Huawei’s Kirin 970 is a 10nm chip designed for AI computing, featuring the world’s first dedicated NPU (Neural Processing Unit). It was launched in September 2017 and powered Huawei’s Mate 10 flagship phone. Unlike traditional architectures, the Kirin 970 uses a heterogeneous computing model, integrating CPU, GPU, ISP, DSP, and NPU for optimized AI performance.
**AI Capabilities**
The Kirin 970’s NPU provides exceptional energy efficiency and performance for AI tasks, offering 50 times better energy efficiency and 25 times higher performance than four Cortex-A73 cores. It can process around 2000 images per minute, making it ideal for real-time AI applications.
**GPU and Connectivity**
The Kirin 970 uses the Mali-G72 GPU, which offers improved performance over previous generations. It also supports LTE Cat.18, delivering download speeds up to 1.2Gbps, slightly ahead of the Snapdragon 835’s Cat.16.
**Comparison: Kirin 970 vs. Snapdragon 835**
Both chips use 10nm processes, but they differ in architecture and performance. While the Snapdragon 835 excels in GPU performance and overall speed, the Kirin 970 leads in AI capabilities and network support. However, the Kirin 970 may face challenges from future chips like the Snapdragon 845 and Exynos 9810.
Overall, the Kirin 970 is ideal for users prioritizing AI and network performance, while the Snapdragon 835 remains a strong choice for those seeking top-tier general performance.
