The Kryo 485 CPU features a prime core capable of up to 2.84 GHz clock frequency. The 855 comes with a built-in Snapdragon X24 LTE modem but is presumably designed to work with an external 5G modem chip.
Graphics are improved with the Adreno 640 GPU and the Hexagon 690 DSP has been rebuilt for AI, with vector accelerators and a Tensor accelerator. This allows for voice and audio enhancements based on machine learning such as Elevoc's noise cancellation and voice-recognizing assistants from Google, Amazon and Baidu.
Qualcomm said it has also revamped its AI software engine to its fourth version. Together with the hardware support this is now three times the performance of its predecessor, the company said.
The Snapdragon includes a dedicated computer vision image signal processor core, the Spectra 380 and for rendering the chip includes the Adreno 640 GPU, which supports Vulkan 1.1 API.
