Exynos 2600 engineering sample touches new single-core record in Geekbench 6

Leaked Exynos 2600 Engineering Sample Hits M5-Class Single-Core Speed, Outruns Every Mobile SoC

Samsung’s next flagship mobile processor, the Exynos 2600, is showing serious momentum in early testing. Fresh Geekbench 6 results from an engineering sample suggest the company’s first 2nm GAA chipset can push a prime core to 4.20GHz, with single-core performance that reportedly matches Apple’s M5. For a smartphone-class SoC, that is a bold statement—even with all the usual caveats that come with pre-production silicon.

Here’s what the new data points to. The Exynos 2600 is built around a deca-core CPU in a 1 + 3 + 6 cluster. In this run, clock speeds were recorded at 4.20GHz for the prime core, 3.56GHz for the three performance cores, and 2.76GHz for the six efficiency cores. A listing shared by @lafaiel on X showed the chip scoring 4,217 in single-core and 13,482 in multi-core on Geekbench 6.

Important note: the same entry could not be located later in the public database. That may mean the listing was removed or that the figures were inaccurate. Treat these numbers as preliminary until more consistent, verifiable results appear.

Compared with earlier Exynos 2600 runs, the gains are substantial, particularly in single-core performance:
– Exynos 2600 (previous): 3,455 single-core, 11,621 multi-core
– Exynos 2600 (latest): 4,217 single-core (+22%), 13,482 multi-core (+16%)

Against Apple’s M5 reference numbers:
– Apple M5: 4,263 single-core (about 1.09% ahead of the latest Exynos 2600), 17,862 multi-core (around 32% higher)

If these results hold, the Exynos 2600 would effectively top the smartphone field in single-core speed while still trailing in multi-core throughput versus Apple’s latest desktop-class silicon. That single-thread leap matters for responsiveness, app launch times, and general UI fluidity—areas users feel immediately.

Power draws were not shared alongside this new leak. However, earlier testing indicated the Exynos 2600 completed a Geekbench 6 multi-core run with board power around 7.6W, claimed to be roughly 59% lower than Apple’s A19 Pro in the same scenario. Combined with the move to a 2nm gate-all-around process, the data points to Samsung pushing both frequency and efficiency—likely probing the upper limit of what this architecture can sustainably deliver in a phone chassis.

What happens next is all about validation and thermals. Engineering samples are often overclocked to explore headroom, and final retail clocks can change once heat, battery life, and sustained performance are balanced. With the Galaxy S26 lineup reportedly slated for February 2026, there’s still time for optimization and for more reliable, repeatable benchmarks to surface.

Bottom line: the Exynos 2600’s early numbers are eye-catching, especially in single-core performance. Keep expectations measured until broader, verifiable results arrive, but Samsung’s 2nm GAA push looks increasingly competitive—and potentially transformative for next-gen Galaxy performance.
