Samsung has begun developing its answer to the 2nm A19 chipset for Apple smartphones

It seems like the era of 3nm chips has just begun, and already companies like TSMC and Samsung Foundry are poised to start mass producing flagship smartphone application processors (APs) on a 2nm node in the second half of next year. The first 2nm process node, known at Samsung Foundry as SF2, will be used to produce Samsung’s Exynos 2600 APs.

Apple CEO Jeff Williams reportedly recently met with TSMC president and co-CEO Xi Xi Wei to discuss reserving 2nm production for its A, M and AI series chips in 2025. Samsung hopes to match Apple and, according to ET News (via SamMobile), has begun development of a chip codenamed «Thetis» that will be mass-produced by Samsung Foundry using the 2nm process starting next year.

Samsung is hoping to make its A-series chips in 2025, which will be mass-produced by Samsung Foundry using the 2nm process starting next year.

This chip, as we’ve noted, will be the Exynos 2600, and if Samsung continues its dual-chip strategy for the 2026 flagship lineup, we can expect the Galaxy S26 and Galaxy S26+ to run on the Exynos 2600 everywhere but the U.S., China, and Canada. In these three markets, the Galaxy S26 and Galaxy S26+ will be powered by the Snapdragon 8 Gen 5 SoC. The latter chip will be used in the Galaxy S26 Ultra in all markets.

Earlier this month, we told you that the Exynos 2600 SoC will be the first chipset to feature Samsung’s own GPU. It will replace the AMD GPU that was used in the Exynos 2400 AP and will be used in the Exynos 2500. But if previous rumors and the latest ET News report are true, Samsung will turn to in-house development to produce the GPU that will be used in the Exynos 2600.

Samsung will turn to its own design to produce the GPU that will be used in the Exynos 2600.

If all goes according to plan, the iPhone 17 series will be the first smartphone to use a 2nm chipset in September 2025, when Apple unveils and releases the iPhone 17 series. This year, we will see a single 2nm chipset being used in the iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max and iPhone 17 Ultra. Samsung won’t move to the 2nm Exynos 2600 SoC until January/February 2026, when the Galaxy S26 series will be introduced and released.
