Qualcomm held its Snapdragon Summit 2022 in Hawaii this morning, where it officially unveiled its new flagship Snapdragon 8 Gen 2 processor, which has been improved in every way compared to its first generation.

The Snapdragon 8 Gen 2, model number SM8550-AB, is built on a 4nm process and here are more details about the chip.

CPU and GPU

While Qualcomm is currently focusing on improving energy efficiency, the new chip still delivers significant speed improvements, with the new processor delivering up to 35 per cent more CPU performance and 40 per cent more power efficiency than Snapdragon 8 Gen 1.

Snapdragon 8 Gen 2 has the same clock speeds as 8+ Gen 1, but a different core composition. The new processor features a new 1+2+2+3 architecture, with one super-core Kryo Prime core (based on Cortex-X3) running at 3.2GHz for high single-threaded performance. There are also four performance cores running at 2.8GHz to better handle multi-threaded workloads. Finally, there are three efficiency cores at 2.0GHz.

Snapdragon 8 Gen 2 brings support for new, faster memory technologies. Memory now supports LP-DDR5X at up to 4,200MHz (up from 3,200MHz in LP-DDR5) and storage supports the new UFS 4.0.

Snapdragon 8 Gen 2 features an Adreno GPU with a 25% performance boost and a 45% increase in power efficiency, as well as bringing support for hardware-accelerated ray tracing to the Snapdragon platform. In addition, this GPU is the first to support Vulkan 1.3 (and OpenGL ES 3.2).

Snapdragon 8 Gen 2 supports QHD+ resolution displays up to 144Hz refresh rate, or 4K displays at 60Hz, as well as external displays up to 4K at 60Hz (with 10-bit Rec.2020 colour gamut, HDR10+ and Dolby Vision capabilities). AV1 video decoding is also supported, with support for up to 8K, 60fps streaming (including HDR).

Camera

Qualcomm claims that Snapdragon 8 Gen 2 has been optimised for Digital Overla HDR (DOL-HDR)-enabled Sony sensors and Samsung's 200 megapixel HP3 sensor to work with Snapdragon ISPs. Like its predecessor, Snapdragon 8 Gen 2 features an 18-bit triple ISP that can handle data from three 36MP cameras (30fps) simultaneously, with pixel support for individual cameras up to 200MP, as well as a 108MP sensor with zero shutter lag.

For video, the chipset can capture 8K HDR footage at 30fps (and simultaneous 64MP photos), 4K footage at 120fps and also supports slow motion video (720p at 960fps). A wide range of HDR formats are supported, including HDR10+, HLG and Dolby Vision.

Networking

Snapdragon 8 Gen 2 is upgraded to the new Snapdragon X70 modem, which supports both millimetre wave and sub 6GHz 5G networks. It has a peak downlink speed of 10Gbps and a peak uplink speed of 3.5Gbps (similar to its predecessor).

The modem supports dual SIM, dual activation (DSDA) operation, where two 5G SIMs (or 5G+4G) can be activated simultaneously.

Thanks to the new FastConnect 7800 system, Snapdragon 8 Gen 2 supports the Wi-Fi 7 standard (802.11be) with a maximum speed of 5.8Gbps (up from 3.6Gbps previously). In addition to speed, the new standard also reduces latency.

As before, the FastConnect system supports Bluetooth 5.3 and offers lossless music streaming at 48kHz and the lowest 48ms latency ever through the latest Snapdragon audio system. For wired connectivity, the chip supports USB 3.1 and Quick Charge 5.

AI

The new Hexagon processor introduces support for the new INT4 format, a first for a Qualcomm mobile chip, with a 60 per cent increase in performance per watt over the previous one.

Hexagon is also faster overall and the AI has been improved by 4.35 times to improve the quality of photos by recognising which parts of an image are faces, hair, clothes, backgrounds and more.
