Samsung has officially announced the Exynos 2600, describing it as the world’s first smartphone system-on-chip manufactured on a 2nm Gate-All-Around (GAA) process, and multiple outlets expect it to appear in at least some Galaxy S26 and S26 Plus models depending on region. Samsung and industry coverage say the move targets familiar user concerns—especially sustained performance and heat—by pairing the 2nm node with new thermal/heat-transfer design choices. Samsung also says the chip brings upgrades across CPU, GPU, AI, and camera processing, signaling a push to keep more flagship silicon development “in-house” alongside its foundry roadmap.

Highlights:

• CPU layout: Android Authority reports a 10-core CPU based on Arm v9.3, using Samsung’s new C1-Ultra and C1-Pro cores.
• Leak clocks: Tipster Ice Universe claims the prime core hits 3.9GHz, with three performance cores at 3.25GHz and six mid cores at 2.75GHz.
• AMD graphics: A leak cited by Android Headlines says the chip uses an AMD “Juno” GPU at 985MHz, with OpenGL ES 3.2, OpenCL 3.0, and Vulkan 1.3 support.
• Mass production: DigiTimes, citing Yonhap News and The Korea Herald, says Samsung published a full spec sheet and confirmed the 2nm application processor is in mass production via Samsung’s System LSI and foundry stack.
• Sustained cooling: SamMobile says Samsung is promising better sustained performance via “innovative heat transfer technology,” a specific response to past throttling complaints.

Perspectives:

• Samsung (product positioning): Samsung frames Exynos 2600 as an industry milestone—the first 2nm GAA smartphone SoC—and emphasizes improved sustained performance through heat-transfer design. (SamMobile)
• Tech press (buyer reassurance): Digital Trends says Samsung is explicitly trying to calm long-running buyer worries about Exynos-equipped Galaxy models by highlighting efficiency, thermals, and overall capability. (Digital Trends)
• Leak community (configuration expectations): Android Headlines presents the split as likely regional, with some Galaxy S26/S26+ units using Exynos 2600 while others use a Snapdragon alternative, and claims the Ultra model won’t use Exynos. (Android Headlines)
