Qualcomm has revealed details about its Snapdragon 865 soc. The new top model can be combined with up to 16GB lpddr5 memory and can capture 4k videos at 120fps. The soc can drive screens with qhd+ resolution at 144Hz.

The Snapdragon 865 has eight Kryo 585 cores, which are clocked at a maximum of 2.84GHz. The clock speed is equal to the Snapdragon 855 and again the soc is made at 7nm. According to Qualcomm, however, the updated cores perform up to 25 percent better than the predecessor. These are cores based on Arm’s Cortex-A77 design.

Qualcomm combines the CPU with an Adreno 650 GPU, which should be up to 20 percent faster than the Adreno 640 from the Snapdragon 855. Manufacturers can combine the Snapdragon 865 with lpddr5 memory at up to 2750MHz or lpddr4x at 2133MHz. The maximum memory size is 16GB.

Qualcomm gives the soc a Spectra 480 isp. It consists of a dual 14bit image signal processor that can process 2 gigapixels per second. That makes it possible to capture 200-megapixel photos and record videos in 8k resolution at 30fps. With 4k videos, that is a maximum of 120fps. Slow-motion recordings at 960fps are also possible at a 720p resolution.

The soc can record HDR videos with Dolby Vision. Support for hdr10+, hdr10 and hlg was already in the Snapdragon 855 and that also applies to the new model. The SD865 can drive smartphone screens with a 4k resolution at 60Hz. At qhd+ resolutions, the maximum refresh rate is 144Hz.

Qualcomm does not integrate a modem in the Snapdragon 865. The manufacturer presents the soc as a 5g platform in combination with the X55 modem that was announced at the beginning of this year. That is Qualcomm’s fastest 5G modem, with support for low and high frequencies and a maximum download speed of 7.5Gbit/s. The upload speed is a maximum of 3Gbit/s. Manufacturers can only use the X55 and all phones with Snapdragon 865 must therefore have an X55 modem with 5G support on board.

The reason for the omission of the modem is the design process for 5g phones. That requires more time than with the already known 4g models and manufacturers could already start designing for next year by making the phones with a Snapdragon 855 with X55 modem. Now that the 865 is here, they can optimize the software for the new soc without doing extra work for the modem.

At the announcement, Nokia licensee HMD Global, Xiaomi and Oppo already announced that they would use the soc in devices that they will announce soon. At the presentation of the Snapdragon 865, Qualcomm also disclosed details of the Snapdragon 765 and 765G. Those midrange socs do have an integrated 5g modem, which supports both low and high frequencies, but at a lower speed than the X55 modem with which the SD865 is combined.
