Qualcomm may follow up its 7nm modem with a 7nm chipset: the Snapdragon 855

Qualcomm unveiled its first 7nm chips yesterday. But theres more to the story Qualcomm contractors may be gearing up to build the Snapdragon 855 on a 7nm process as well.

Qualcomm won’t say it, but their contractors do. Snapdragon 855 (SDM855) is the first 7nm SoC. (probably the one the X24 modem ends up in)

The upcoming 845 chip is being built on a 10nm Low Power Plus process, an incremental upgrade over the 10nm Low Power Early process used in the 835. Samsung (which is fabbing the chips) claims 10% higher performance or 15% power reduction.

Early Snapdragon 855 rumors pointed to TSMC as fab that will build the 2019 chips. However, Qualcomm didnt say who is building the X24 modem likely the same fab that will make the 855.

If it is TSMC (which is looking like the more probable version right now), it claims up to 40% power reduction or 37% or more increase in performance over their 10nm process, a pretty significant jump.
