After officially unveiling the Snapdragon 855 yesterday, Qualcomm today is fully detailing the specs for its next-generation chip specs for 2019 Android flagships. The processor focuses on adding 5G support to phones, as well as improved artificial intelligence and mixed reality experiences.
The Snapdragon 855 is built on a 7nm process with the Kyro 485 CPU delivering a 45% performance improvement over the 845. This octa-core 64-bit architecture is comprised of one prime core clocked up to 2.84GHz and three performance cores operating at up to 2.42GHz, as well as four efficiency cores clocked up to 1.80GHz.
Meanwhile, the all-important Adreno 640 GPU provides 20% faster graphics with Vulkan 1.1 API support, as well as OpenGL ES 3.2 and OpenCL 2.0 FP. HDR Playback Codec supports HDR10+, HDR10, and Dolby Vision for high-quality and battery efficient video watching. It can support a 4K HDR on-device display, as well as two external screens of equivalent resolution. There is also a hardware-accelerated H.265 and VP9 decoder.
On the gaming front, the 855 allows for “cinematic color grading in true HDR,” while mixed reality experiences include volumetric VR and 8K 360 VR video playback.
On the AI front, a 4th-generation multi-core Qualcomm AI Engine and Hexagon 690 Processor allows for a 3x AI performance improvement compared to last year, which benefits Android’s Neural Network API. In practice, this can also help voice assistants by delivering better echo cancellation and noise suppression.
The advantages of computational photography got a big showcase with the Pixel 3 over the past few weeks. The 855 features what Qualcomm calls a Computer Vision Image Signal Processor (CV-ISP) with the Spectra 380 ISP.
It allows for 22MP 30FPS concurrent dual cameras and a 48MP at 30FPS single camera, with hardware-based depth sensing allowing video capture, object classification, and object segmentation in real-time at 4K HDR and 60FPS. In practice, this allows video capture with real-time object or background replacement.
On the video front, HDR10+ video capture saves more than 1 billion shades of color, while 720p slow motion video at 480FPS is possible. HEVC (H.265) video capture and HEIF photo capture works to reduce file sizes by 50%.
For connectivity, the 855 supports multi-gigabit 5G, but only the existing Snapdragon X24 LTE modem is built-in. The Snapdragon X50 modem supports 5G for both Sub-6 GHz and mmWave frequency bands, with the latter allowing for 20x faster average performance compared to today’s connectivity. The 855 also supports 802.11ay Wi-Fi that promises 10Gbps and wire-equivalent low latency.
The first commercial devices featuring the Snapdragon 855 will ship in the first half of 2019.
