The Galaxy S26 Ultra has been benchmarked in the wild — and two of the three numbers are exactly what Samsung needed. A production unit posted by tipster Sahil Karoul on X shows an AnTuTu score of 3,720,219, Geekbench 6 single-core of 3,648 and multi-core of 10,898, and a 3DMark Wild Life Extreme Stress Test stability of 53.2% with a 34°C–44°C temperature range. That last result is the headline: the S25 Ultra hit 70% stability but ran nearly 20°C hotter under the same test — meaning the S26 Ultra is running cooler in sustained load despite the more powerful chip.

Galaxy S26 Ultra vs S25 Ultra: Benchmark Comparison
The Snapdragon 8 Elite Gen 5 for Galaxy is a custom Samsung-tuned version with prime cores overclocked to 4.74GHz — higher than the standard chip used by other Android flagships.
| Benchmark | Galaxy S26 Ultra | Galaxy S25 Ultra | Change |
|---|---|---|---|
| AnTuTu | 3,720,219 | 2,441,258 | +52% |
| Geekbench 6 Single-Core | 3,648 | 3,057 | +19% |
| Geekbench 6 Multi-Core | 10,898 | 9,846 | +11% |
| 3DMark WLE Stability | 53.2% | ~70% | Lower stability |
| Peak Temperature (3DMark) | 44°C | ~63°C | 19°C cooler |
| Temperature Rise | 34°C → 44°C (+10°C) | ~43°C → 63°C (+20°C) | Half the rise |
| Chipset | Snapdragon 8 Elite Gen 5 for Galaxy | Snapdragon 8 Elite for Galaxy | Gen bump |
| Prime Core Clock | 4.74GHz (×2) | 4.47GHz (×2) | +6% |
| Perf Core Clock | 3.63GHz (×6) | 3.53GHz (×6) | +3% |

| Cooling | Larger vapor chamber (confirmed) | Standard vapor chamber | Bigger |
| RAM | Up to 16GB | Up to 12GB | +4GB top tier |
What 53.2% Stability Actually Means
The 3DMark stability number looks worse on paper — the S25 Ultra’s 70% is a higher percentage. But stability in this context measures how consistently the device maintains peak GPU output across the full stress test. A lower stability with a much lower temperature tells a different story: the S26 Ultra’s Adreno 840 is being allowed to push higher GPU frames early in the test, which then drops more as thermals accumulate — but it’s doing all of this at 44°C peak, not 63°C.
The practical implication: in 15–20 minute gaming sessions, the S26 Ultra runs meaningfully cooler and more comfortably in hand. The larger vapor chamber Samsung confirmed is doing real work — halving the temperature rise from 20°C delta to 10°C delta is a significant engineering achievement given the prime cores are running 6% faster than the S25 Ultra’s.
The AnTuTu jump of 52% over the S25 Ultra is the biggest single-generation gain in the Galaxy S Ultra line in at least three years. The multi-core Geekbench crossing 10,000 for the first time in Galaxy history is a milestone Samsung will lean into heavily in its Unpacked marketing.
The one caveat: these are pre-launch results from a production unit sold early at a Dubai retail store. Software optimisation isn’t final, and launch-day One UI 8.5 tuning could shift any of these numbers in either direction.

FAQs
What are the Galaxy S26 Ultra AnTuTu and Geekbench scores?
The Galaxy S26 Ultra scored 3,720,219 on AnTuTu — up 52% from the S25 Ultra — and 3,648 single-core / 10,898 multi-core on Geekbench 6, the first Samsung Ultra to cross 10,000 multi-core.
Has Samsung fixed the Galaxy S26 Ultra thermal throttling problem?
Yes — the S26 Ultra peaks at 44°C during sustained GPU load, versus ~63°C on the S25 Ultra under the same test, a 19°C improvement attributed to a larger confirmed vapor chamber and One UI thermal tuning.
