Qualcomm’s Snapdragon 8 Gen 2 processor improves artificial intelligence

Qualcomm on Tuesday announced the Snapdragon 8 Gen 2, its flagship mobile system on a chip that will power the world’s most important Android system. The telephones Y tablets for next year. The company focused on adding features into the silicon that it says will bring “innovative AI” to multiple aspects of the mobile experience.

Key features include Snapdragon Smart, which boosts the chip’s AI performance, Snapdragon Sight for better object recognition, Snapdragon Elite Gaming, which adds hardware-accelerated ray tracing support, Snapdragon Connect for AI-powered connectivity, and Snapdragon Sound for spatial, lossless audio. support for.

The first commercial devices are expected to hit the market before the end of the year.

Qualcomm relies on its redesigned CPU combined with upgrades to the GPU, Hexagon processor, and Sensung Hub to create new AIs in the 8 Gen 2. It is based on a 4nm process in the Kryo CPU, which is made up of a single core. main powered by an Arm Cortex-X3 up to 3.2 GHz, four performance cores up to 2.8 GHz, and three efficiency cores up to 2.0 GHz. 8 generation 1, for comparison, had one main core, three performance cores, and four efficiency cores. Qualcomm says that this new arrangement offers 40% more performance without affecting battery life.

The company overhauled the Hexagon processor with an AI accelerator architecture fused with an updated Tensor accelerator, vector extensions, scalar accelerator, and Direct Link. Combined with the new Sensing Hub, which contains two AI audio processors and support for constant detection cameras, the 8 Gen 2 offers up to 4.35 times the AI ​​performance of the previous generation chip and increases efficiency by 60%. %. This will also allow phone manufacturers to bring more on-device natural language processing to their hardware in a similar way to Google’s Tensor technology. pixel smartphones.

Snapdragon Sight is actually aiming to increase the power of smartphone cameras. The Spectra Image Signal Processor supports image sensors up to 200MP in various configurations, as well as 8K video capture with 64MP stills, 8K60 playback, 10-bit color, and exposure-based autofocus, face recognition, and exposure. in AI. Qualcomm says these new features enable secure facial recognition for phone locks, with future devices capable of accounting for facial features, hair, eyes, skin, and more. In addition, Qualcomm is working more closely with image sensor makers Samsung and Sony to better integrate these features into future phone cameras.


entertainment abounds

Qualcomm says that 8 Gen 2 will bring new and richer entertainment experiences to mobile devices. For example, the revised GPU is 25% faster and supports hardware-accelerated ray tracing. This will be a boon on the mobile gaming front as it will offer more realistic lighting and shadow effects in games. The GPU also supports HDR 10, HDR 10+, Dolby Vision, 10-bit color, hardware-accelerated H.265 and V9 decoding, as well as OpenGL ES 3.2, OpenCL 2.0 and Vulkan 1.3. This will allow game developers to push the limits and create more immersive worlds.

Display support covers displays up to 4K at 60Hz or QHD+ displays up to 144Hz. Most of today’s best phones have QHD+ displays with refresh rates up to 120Hz, but 8 Gen 2 will allow users to Phone makers improve those specs a bit more. The chip also supports sub-pixel rendering for OLED uniformity and OLED anti-aging compensation to reduce burn-in.

The Snapdragon 8 Gen 2 pushes the limits of audio thanks to a new version of Snapdragon Sound. Revised audio enables 48KHz lossless audio for music streaming, helping bridge the last mile between mobile phones and wireless headphones. It also features spatial audio with dynamic head tracking for a complete surround sound experience. Qualcomm hasn’t forgotten about gamers, who will be able to take advantage of new low latency game modes that reduce audio delay to 48ms.


high speed connections

Qualcomm claims its new Snapdragon Connect platform is the “most advanced 5G platform in the world.” It takes every potential connection and adds a dose of AI for on-device performance improvements across the board.

Snapdragon Connect is paired with the Snapdragon X70 5G modem and RF system, which is betting on artificial intelligence to balance 5G upload and download speeds with coverage, latency and energy efficiency. Importantly, it’s the first to support 5G dual SIMs, meaning people can run two 5G connections to one device at once for work and personal numbers. Peak download speeds can reach 10 Gbps over 5G, while upload speeds exceed 3.5 Gbps. Supports 5G mmWave and sub-6GHz in standalone and non-standalone modes

Although the Wi-Fi Alliance has not finalized the Wi-Fi 7 specifications, Qualcomm is moving forward with Wi-Fi 7 through the Qualcomm FastConnect 7800 connectivity system. The company says the 7800 offers low-latency Wi-Fi 7 performance with downloads reaching 5.8 Gbps. Other Wi-Fi features of the 7800 include 8×8 MIMO, 4K QAM, simultaneous dual-band (2×2, 2×2), as well as WPA3 enterprise-grade security.

Bluetooth support ranges up to version 5.3 with aptX audio, aptX Adaptive, aptX Lossless and LE codecs.

The chip includes almost all global location systems, such as GPS, Glonass, Galileo, QZSS, and NavIC. It has dual-band L1/L5 GPS for better urban pedestrian tracking, which will lead to better street-level mapping experiences when walking between tall buildings.

Other minor features of the Snapdragon 8 Gen 2 include support for up to 16GB of LPDDR5x memory up to 4200MHz, USB 3.1, USB-C, UFS 4.0, and a Secure Processing Unit for better enterprise security performance. Qualcomm QuickCharge 5.0 is integrated for fast power-ups.


Coming soon

Qualcomm announced that a large number of hardware partners have already signed up to adopt the 8 Gen 2. Some phone manufacturers include Asus, Honor, Motorola, OnePlus, Oppo, and Sony. Some of the device manufacturers will have 8 Gen 2 products on the market by the end of the year.
