Leaked Exynos 2600 Specs Point to 10-Core Lumex CPU, AMD GPU on 2nm for Galaxy S26

Samsung has named the chip, with detailed performance and deployment claims still unverified.

Overview

  • Tipster posts describe a 10-core Arm Lumex CPU on a 2nm Samsung process with clocks up to 3.9GHz for the prime core and 3.25GHz and 2.75GHz for the other clusters, though some reports suggest a 3.8GHz ceiling.
  • The GPU is reported as an AMD JUNO part, also referenced as Xclipse 960, running at 985MHz with support for OpenGL ES 3.2, OpenCL 3.0 and Vulkan 1.3.
  • Reporting indicates Galaxy S26 and S26+ models will use Exynos 2600 in most markets, with Canada, China and the United States expected to receive Snapdragon-based versions.
  • The Galaxy S26 Ultra is expected to ship globally with Qualcomm’s Snapdragon 8 Elite Gen 5.
  • Claims of improved thermals, including a Heat Path Block design, and any performance leads over rival chips remain unproven ahead of launch, with some rumors pointing to a late-January reveal.
