On the second day of the technology summit, Qualcomm once again took the spotlight with its Snapdragon 845 processor. Today, I’ll dive deeper into this powerful chip and explore what makes it stand out in the world of mobile technology.
Since the early days of 3G technology, Qualcomm has been at the forefront of innovation. In 1999, the first 3G mobile phone was launched, and in 2007, the first mobile device featuring an Opteron processor hit the market. Over the years, Qualcomm has continuously evolved, reaching new heights in the 4G era. Last fiscal year alone, they sold around 800 million Opteron processors globally, with over 120 different products supporting them. This widespread adoption is a testament to Qualcomm’s deep technological expertise. The company invests heavily in R&D, spending over $1 billion each quarter. For instance, the Snapdragon 845, which we’re discussing today, was actually developed three years ago.
As mentioned yesterday, the Snapdragon 835 focused on enhancing user experience, immersive features, AI capabilities, security, connectivity, and performance. The Snapdragon 845 builds on that foundation while introducing several key improvements.
Looking at the architecture, the Snapdragon 845 uses a 10nm LPP process, featuring an Adreno 630 GPU, X20 LTE modem, Spectra 280 ISP for video processing, and a Hexagon 685 DSP coprocessor. It also includes Qualcomm Aqstic Audio for better sound quality and a Kryo 385 CPU with four 2.8GHz big cores and four 1.8GHz small cores, along with 2MB of cache. Additionally, it comes with a dedicated memory module and a secure security chip.
The Kryo 385 CPU consists of four 2.8GHz A75 cores and four 1.8GHz A53 cores, offering a 25–30% improvement in performance over the previous generation. The small cores also see a 15% boost in efficiency. The Adreno 630 GPU delivers 30% more graphics performance, 2.5 times higher throughput, and 30% lower power consumption compared to its predecessor.
In terms of connectivity, the Snapdragon 845 features the X20 LTE modem, capable of up to 1.2 Gbps download speeds, dual SIM support, and Wi-Fi 11ac with speeds up to 16x faster. This ensures fast and stable connections for users.
One of the standout features of the Snapdragon 845 is its focus on immersive experiences. Qualcomm introduced the concept of "XR," which combines VR, AR, and MR. The 845 is the first mobile platform to support room-scale 6DoF and SLAM (Simultaneous Localization and Mapping), allowing for more natural and interactive augmented reality experiences. The Adreno Vision Focus feature also helps reduce power consumption while improving visual quality and performance in XR applications.
The Spectra 280 ISP has been upgraded to the second generation, offering improved color depth and wide color gamut support. With 10-bit color depth, it can capture more nuanced details in images, especially in scenes like the sky, where subtle color variations are common. The ISP also supports hardware acceleration for video recording, making it easier to capture high-quality footage.
Security is another major focus of the Snapdragon 845. It includes a dedicated Security Processing Unit (SPU) with its own power supply and flash memory. This unit securely stores biometric data such as fingerprints and facial recognition, as well as sensitive information like banking details. This makes the 845 one of the most secure mobile platforms available.
In terms of battery life, the Snapdragon 845 supports QC4.0 fast charging, allowing users to charge their devices to 50% in just 15 minutes. It also uses AI to optimize power consumption, extending battery life for tasks like 4K video playback and VR gaming.
For artificial intelligence, the Snapdragon 845 doesn’t have a dedicated NPU like Huawei’s Kirin 970, but it leverages the CPU, GPU, and DSP for AI tasks. This approach allows for more flexible and efficient AI processing across different applications. The AI performance is three times better than the previous generation, improving voice interaction, gaming, and other real-time tasks.
The Snapdragon 845 supports popular AI frameworks like TensorFlow and ONNX, ensuring compatibility with a wide range of applications. While it may not match the raw speed of Apple or Huawei’s AI solutions, it offers a balanced approach, optimizing performance based on the specific needs of each application.
Overall, the Snapdragon 845 represents a significant step forward in mobile computing, combining performance, efficiency, and advanced features that cater to both everyday users and developers. Whether you're gaming, streaming, or using AR/VR, the 845 delivers a smooth and immersive experience.
