**A11 Bionic Chip**
The A11 Bionic chip features a custom-designed CPU, GPU, performance controller, neural engine, and ISP. Apple has taken a significant step forward with the A11, which includes a six-core CPU design composed of two high-performance cores and four energy-efficient cores. This architecture allows for improved performance and power efficiency. Compared to the A10 Fusion, the performance cores have seen a 25% speed increase, while the energy-efficient cores are 70% faster, resulting in a major leap in overall performance. Additionally, Apple introduced a second-generation performance controller that enables full utilization of all six cores, providing up to 70% better performance for multi-threaded tasks. Benchmarks suggest that the A11 is extremely powerful, with impressive scores already being reported.
**Kirin 970**
Huawei’s Kirin 970 is the first mobile chip to integrate an NPU (Neural Processing Unit) into its design, using the HiAI mobile computing architecture. This makes it highly efficient at handling AI tasks, offering up to 50 times better energy efficiency and 25 times more performance than traditional CPU or GPU-based solutions when running AI applications. For example, it can process up to 2,000 images per minute for image recognition. The Kirin 970 also uses a Mali-G72 GPU, with 12 cores compared to the 8 cores in the Kirin 960, and supports LTE Cat.18 with speeds up to 1.2 Gbps. Built on a 10nm process, it improves power efficiency by around 20%, making it a strong competitor in the mobile chip market.
**Snapdragon 835**
Qualcomm’s Snapdragon 835 is built on Samsung’s 10nm FinFET process, offering a 27% performance boost and 40% improvement in energy efficiency over the previous 14nm generation. It features an eight-core Kryo 280 CPU with two high-performance cores running at 2.45GHz and six smaller cores at 1.9GHz, along with an Adreno 540 GPU. The chip supports 4K displays, UFS 2.1 storage, dual cameras, and LPDDR4x memory. It also integrates a Cat.16 modem and supports Quick Charge 4.0, offering 20% faster charging and 30% higher efficiency. The Snapdragon 835 was one of the most powerful chips in 2017, dominating the top of the CPU rankings for much of the year.
**Comparison of Key Performance Metrics**
In 2017, the mobile chip landscape saw major advancements from Apple, Huawei, and Qualcomm. The A11 Bionic outperformed both the Kirin 970 and Snapdragon 835 in traditional CPU benchmarks, showing massive improvements in single- and multi-core performance. The Kirin 970, however, gained attention for its AI capabilities, thanks to the integrated NPU, which allowed it to excel in machine learning tasks. The Snapdragon 835 remained a strong performer, especially in gaming and general computing, but struggled to match the A11 in raw CPU power. While the Kirin 970 and Snapdragon 835 were competitive in standard benchmarks, the A11’s dominance was clear, especially in real-world usage scenarios. Looking ahead, the release of the Snapdragon 845 in 2018 promised even greater improvements, potentially setting a new standard for mobile processors.
