Samsung has unveiled its latest chipset, the Exynos 2600, and this one’s a milestone. The Exynos 2600 is the world’s first 2nm smartphone processor, built using Samsung Foundry’s 2nm GAA process. Mass production is reportedly already underway, and it’s expected to power the Galaxy S26 and S26+ that launches early 2026, though Samsung hasn’t commented officially on this yet.
For the unversed, 2nm refers to the latest generation of chip manufacturing technology. In practical terms, moving from 3nm to 2nm allows chipmakers to pack more transistors into the same space, which translates to better efficiency and higher performance at similar power levels. Most current flagship phone chips are still based on 3nm, so Samsung is ahead of the curve here.
Historically, Exynos chips performed pretty well at first but then would start to degrade once warmed up, especially when running games or during prolonged camera use. To counter that, the Exynos 2600 features a new cooling technology called Heat Path Block (HPB). What it aims to do is move heat away from critical areas more efficiently using a High-k EMC material, so performance doesn’t drop off as quickly. How efficiently this works will become clear once devices start shipping.
On the CPU side, the Exynos 2600 uses a 10-core setup based on Arm’s new v9.3 architecture. There’s one prime C1 Ultra core clocked at 3.8GHz, three C1 Pro cores at 3.25GHz, and six more C1 Pro cores running at 2.75GHz. Notably, Samsung has dropped traditional efficiency cores altogether. Instead, it’s betting that newer high-performance cores can scale better across both light and heavy workloads. Samsung claims this will bring a 39 percent performance improvement over the Exynos 2500, which is present in the Samsung Galaxy Z Flip7. How much of this translates into real-world gains will depend heavily on thermals and power management.
Logically, AI is another area where the Exynos 2600 looks to improve things. The new NPU reportedly delivers 113 percent better AI performance than the previous flagship Exynos chip. It also introduces features like hardware-backed post-quantum cryptography. For users, this mainly means faster and more capable on-device AI, so expect faster photo processing, better voice features, and generative tools that don’t constantly rely on cloud servers.
Graphics performance also sees a noticeable jump. The Xclipse 960 GPU offers double the compute performance of the older Xclipse 950, along with improved ray tracing for games. Samsung is again leaning on AI here, using its Exynos Neural Super Sampling technology to boost frame rates and smooth gameplay without pushing power consumption too high.
The camera and video functionalities are in flagship territory. The Exynos 2600 chipset is capable of supporting cameras with a sensor size of up to 320MP, zero shutter delay for 108MP photos, and video recording of up to 8K at 30fps or 4K at 120fps. The power consumption for the new image signal processor has been cut down by 50 percent, which should help with longer recording sessions and low-light video.
The chipset supports LPDDR5X RAM, UFS 4.1 storage, and 4K displays at up to 120Hz, though it appears to rely on a separate modem.
In terms of competition, Samsung definitely seems to have gotten the first-mover advantage but it’s not lone in exploring the 2nm territory. Qualcomm is expected to launch its first 2nm Snapdragon flagship chip in 2026, which will likely manufactured by TSMC. Apple is also planning multiple 2nm products for 2026, including its next iPhone chip and new M-series silicon. MediaTek, meanwhile, has already completed tape-out of its own 2nm flagship SoC, with mass production planned later the same year.
For users, 2nm chipsets mean better battery life, more consistent performance under load, and stronger on-device AI. However, node size alone isn’t enough to guarantee a stronger experience and it would all depend on how well manufacturers control heat, balance power, and integrate these chips into devices.
