Snapdragon 8 Elite: The World’s Fastest Mobile Chip Explained


Qualcomm is renowned for its networking chips, and the Snapdragon 8 Elite is no exception. It features the flagship X80 5G modem and FastConnect 7900, enhancing 5G and Wi-Fi 7 performance.The Snapdragon 8 Elite, Qualcomm’s latest flagship mobile chip, is now official. It boasts custom second-generation Oryon CPU cores with clock speeds up to 4.32 GHz, making it the most powerful mobile chip to date. Qualcomm has named it “Elite” to highlight its significant advancements in the industry.This chip introduces several groundbreaking features, including on-device multi-modal AI capabilities and enhanced CPU and GPU performance. The Snapdragon 8 Elite is manufactured using TSMC’s advanced 3nm process, the same technology used for Apple’s A18 Pro chip in the iPhone 16 Pro.

Simplified CPU and GPU Details

The Snapdragon 8 Elite includes an octa-core CPU with a hybrid architecture: two prime cores at 4.32 GHz and six performance cores at 3.53 GHz. Unlike its predecessor, the Snapdragon 8 Gen 3, which used ARM’s custom Cortex cores, all six CPU cores in the Snapdragon 8 Elite are based on Qualcomm’s custom second-generation Oryon architecture.These cores have access to over 24 MB of L2 cache, the highest in the industry for a mobile chip, and support up to 24 GB of LPDDR5x RAM. This configuration delivers a 50% performance improvement over the Snapdragon 8 Gen 3, a significant leap given the already impressive speed of the previous chip.The new three-core Adreno GPU, clocked at 1.1 GHz, is 40% faster and 40% more power-efficient, with a 35% improvement in ray-tracing performance compared to the Adreno 740 in the Snapdragon 8 Gen 3. It is also the first mobile GPU to support Unreal Engine 5 Nanite, enhancing gaming capabilities.

Snapdragon 8 Elite: On-Device AI Capabilities

Most smartphones today use edge-powered AI, where processing is split between the device and the cloud. The new Hexagon NPU (neural processing unit) in the Snapdragon 8 Elite is 45% faster and 45% more efficient per watt.

This NPU features an 8-core scalar accelerator and a 6-core vector accelerator, supporting large language models (LLM) and traditional AI tasks. It can handle voice input and generate text, images, and audio, enabling advanced on-device AI applications like AI Expansion, super-resolution, and segmentation, which enhance camera and image-editing performance.

The AI-powered Cognitive Image Sensing Processor (ISP) can process up to 4.3 gigapixels per second, support up to 320 MP resolution, and record 8K videos at 60fps.

Top-Tier Networking

Qualcomm’s networking chips are highly regarded, and the Snapdragon 8 Elite includes the flagship X80 5G modem and FastConnect 7900, boosting 5G and Wi-Fi 7 performance.

Benchmark Performance

The Snapdragon 8 Elite excels in benchmarks, scoring 3221 in single-core and 10236 in multi-core CPU tests on Geekbench. While its single-core score is slightly lower than the A18 Pro, it outperforms in multi-core tests due to its eight CPU cores compared to the A18 Pro’s six.On AnTuTu, the Snapdragon 8 Elite scores 3,014,075 points, significantly higher than the A18 Pro’s 1,700,000, showcasing superior GPU, memory, and user experience performance.

Augmented Reality (AR) Glasses Are Making a Comeback

Image
After the initial hype and subsequent stagnation of early augmented reality (AR) glasses like Google Glass, AR technology is experiencing a revival. Improvements in hardware, software, and display technologies have made modern AR glasses more viable for everyday use, potentially setting the stage for mainstream adoption. What Makes Today’s AR Different? The latest generation of AR glasses is vastly more capable than its predecessors. Advances in lightweight materials, miniaturized components, and more efficient display technologies have addressed many of the issues that plagued earlier AR glasses. The displays now offer higher resolution and better color accuracy, while the glasses themselves are more comfortable to wear for extended periods. Another key factor driving the resurgence of AR is the development of more sophisticated tracking and mapping algorithms, known as Simultaneous Localization and Mapping (SLAM). These algorithms allow AR devices to understand the geometry of the ph...

AI-Powered Creativity Takes Center Stage

Image
Artificial Intelligence has emerged as a powerful tool not only for analytical tasks but also for creative endeavors, transforming fields such as art, music, and content creation. The rise of AI-driven creative tools is democratizing access to artistic expression and reshaping industries that were once thought to be purely human domains. The Evolution of AI in Creative Fields Historically, creativity was considered a uniquely human trait. However, advances in machine learning and neural networks have made it possible for AI to generate original works of art, compose music, write stories, and even develop new product designs. Tools like GPT-4 for text generation and DALL-E for image creation have gained popularity among both amateur creators and professionals: Art and Design: AI-generated artwork is no longer a novelty; it's becoming an established part of the art world. Algorithms can analyze thousands of existing artworks to create new pieces that mimic vari...
