Overview
- Samsung is reported to be developing a 2nm external 5G modem called the M2800 with development expected to finish in 2027 and a planned debut in the Galaxy S28 series in 2028.
- In the near term Samsung has refined its 4nm M2700 modem with an optical die shrink and software and voltage tuning to fix standby battery drain seen in earlier Exynos devices.
- The M2700 will pair with the Exynos 2700 in most Galaxy S27 models while Samsung plans to keep Snapdragon chips in the S27 Ultra, according to reporting based on industry sources.
- Samsung plans to move external modems off 4nm manufacturing lines so those fabs can make base dies for High Bandwidth Memory, a component used in AI accelerators and server hardware.
- These plans are drawn from reporting by The Elec and summaries in other outlets and rely on internal test claims that remain developing and not independently verified.
