After announcing the next-generation Snapdragon 845 SoC at the Snapdragon Tech Summit 2017 in Maui, Hawaii, Qualcomm has today detailed the features of the new mobile platform. The new chipset is based on the 10nm FinFET process with big.LITTLE architecture. Qualcomm has already mentioned that the new chipsets will be manufactured by Samsung Foundry. Here are the changes that the new chipset brings over last year’s Snapdragon 835 SoC.
Kryo 385 CPU
The key enhancements over Snapdragon 835 comes in the form of better battery life and faster performance. The chipset is manufactured using Samsung’s second-gen 10nm LPP FinFET process. The Kryo CPU architecture includes four performance cores (Cortex A75) clocked up to 2.8GHz with up to 30 percent performance improvement over Snapdragon 835. These performance cores are paired with four efficiency cores (Cortex A55) clocked at 1.8GHz, which Qualcomm says is 30 percent more energy efficient compared to its predecessor.
The Snapdragon 845 SoC comes with Quick Charge 4 support, which Qualcomm claims can take the battery from empty to 50 percent in 15 minutes. Also, on full charge, the chipmaker says that smartphones powered by Snapdragon 845 SoC can offer around four hours of Ultra HD 4K video playback, up to three hours of immersive unwired VR usage, and talk time of up to two days on VoLTE.
Adreno 630 GPU
The Snapdragon 845 SoC is paired with the Adreno 630 GPU, which Qualcomm says is faster and more efficient in processing. The new GPU is designed to offer 30 percent faster graphics, 30 percent improved energy efficiency and 2.5 times faster display throughput. It will also support 2K + 2K 120fps XR for virtual and augmented reality devices.
X20 LTE modem
The X20 is Qualcomm’s second-generation Gigabit LTE modem with TrueWireless connectivity. It is designed to over 20 percent improvement over X16 modem on the Snapdragon 835 SoC. The X20 modem can offer maximum speeds of up to 1.2Gbps over 12 streams. It comes with 5 carrier aggregation with 4×4 MIMO technology. So, what do these specifications mean? Well, it can offer faster upload and download data speeds on upcoming 5G networks.
It also supports multi-Gigabit Wi-Fi with 60GHz range with ad baseband. The modem also supports Wi-Fi 802.11ac for 16 times faster connection setup and 30 percent efficiency. The X20 modem on the Snapdragon 845 SoC now supports dual-SIM 4G connectivity and Dual-VoLTE on both SIMs. It also comes with advanced Bluetooth capabilities to broadcast HD quality music or live audio to connect to multiple devices. Also, the modem is designed to consume 50 percent less power when using wireless earbuds.
The Snapdragon 845 SoC comes with Hexagon 685 DSP and Spectra 280 ISP (Image Signal Processing) for improved photography. The smartphone camera will also support capturing Ultra HD Premium videos at 60fps. Qualcomm has also made improvements to the ISP to correct the color gamut, color depth and luminance to make your captured photos look more lifelike.
It basically helps to correct the color volume, dynamic range and improve the banding. The new chipset will also support slow-motion video capture at 720p in HDR10 format, with a frame rate of 480fps. The chipset will also consume 30 percent less power when recording videos.
Most smartphones today come with dual-camera setups and they allow capturing photos with DSLR-like bokeh effects. The new Snapdragon chipset comes with ‘Computer Vision’ for depth mapping and to add the depth-of-field effects even when using a single camera. It also supports Face scanning for biometric authentication and security.
Artificial Intelligence and Machine Learning (ML) is everywhere today, right from finance to healthcare, entertainment, insurance, and transportation. The Snapdragon 845 SoC is the third generation mobile AI platform from Qualcomm. With the new chipset, Qualcomm is moving intelligence from cloud to edge to improve low latency, privacy and reliability.
With AI integration, Qualcomm wants to offer richer and more personalized experiences. It works with multiple platforms, such as Android, Linux and Windows, and Qualcomm is working with a number of partners such as Facebook, Google, Amazon Alexa, Baidu, and more for improved experiences.
AI on Snapdragon 845 comes with features such as speech recognition, object detection, face recognition, single camera bokeh effects to your camera photos, landmark detection, malware detection and more.
The security architecture on the Snapdragon 845 SoC comes with a secure vault. It is hardware based and comes with its own Secure Processing Unit to keep your photos, videos, content and other details safe and secure. We have moved from typing passwords to fingerprint scanning, iris scanning and face scanning biometric authentication systems. And because biometrics is important to us from a privacy viewpoint, the data is encrypted and validated in the secure processing unit, thus keeping it secure. Also, with mobile payments becoming increasingly mainstream, the integration of secure vault in the chipset will enable higher level of security of your biometrics.
