Samsung to Move Mobile Modems to 2nm as 4nm M2700 Passes MX Tests
According to industry sources on Oct. 20 (year not stated in the source), Samsung Electronics plans to manufacture its next-generation M2800 series mobile modem chips using a 2nm process, transitioning from the 4nm technology currently used for external modems; the external 5G modem M2800 is scheduled to complete development in 2027, is intended for the Galaxy S28 series due for release in 2028, and will be paired with the next-generation Exynos 2800 in a two-chip configuration. Moving modem production to 2nm will free up capacity on Samsung's 4nm lines, which the company plans to redirect toward HBM production; an industry official said "Samsung Foundry is converting much of its 4nm production capacity to HBM manufacturing," with the 4nm process used for the base die containing control circuitry at the bottom of an HBM stack. Samsung will continue using 4nm through the M2700, an external modem designed to accompany the Exynos 2700 in the 2027 Galaxy S27 series; the Shannon 5410 external modem used in the 2026 Galaxy S26 (also marketed externally as the Exynos Modem 5410) was also manufactured on a 4nm process, with Samsung equipping the South Korean versions of the Galaxy S26 and S26+ with the Exynos 2600 and Shannon 5410 combination while US models used Qualcomm's Snapdragon 8 Elite Gen 5. An industry official said Samsung has discontinued the Shannon modem brand and replaced it with the M-series. Although the M2700 uses the same 4nm process, it reportedly received favorable evaluations in internal testing by Samsung's Mobile eXperience (MX) Business, unlike its predecessor; Samsung improved power efficiency and data transmission speeds through design and software changes, reduced the chip's area by approximately 4% using optical shrink, and moved the modem from 3GPP Release 17 to Release 18 with improved NTN satellite communication capabilities. The official said the existing Shannon 5410 lagged behind competing products in idle power consumption and under standard power measurement conditions, and that the M2700, following voltage adjustments and other improvements, reportedly delivers performance comparable to or better than rival products. The 2nm transition and 4nm capacity conversion are plans; the source does not confirm their implementation.
