it house reported on october 7 that samsung’s upcoming galaxy s25 series is expected to be the company’s first mobile phone using 3nm chips. previous rumors claimed that samsung would use 3nm exynos 2500 in the galaxy s25 and galaxy s25+, and 3nm snapdragon 8 elite in the galaxy s25 ultra. however, the latest reports suggest that this plan may change due to the difficulties the company faces with its own 3nm exynos chips.

according to korean media business korea, samsung’s 3nm exynos 2500 chip is facing yield problems. yield refers to the percentage of all chips that pass quality certification, with the rest discarded. although samsung is confident in its second-generation 3nm process and exynos 2500 chip, the report said its yield rate is low, but no specific data was given.

it house has noticed that samsung’s semiconductor chip foundry business has been facing challenges. despite investing billions of dollars, the company has failed to catch up with tsmc. in fact, the gap between the two is widening. in the second quarter of this year, tsmc’s market share rose to 62.3%, while samsung foundry’s market share dropped to only 11.5%.

if the report is true, samsung may be forced to use the snapdragon 8 elite chip in all galaxy s25 series models - galaxy s25, galaxy s25 + and galaxy s25 ultra - globally. in the past, snapdragon chips have been more powerful and efficient than corresponding exynos chips.
