Samsung's prototype Exynos 2600 is making waves in early benchmark leaks, claiming a dramatic jump in efficiency versus Apple’s A19 Pro. Rumored power-readings from Geekbench 6 point to far lower power draw, and analysts are eyeing Samsung's 2nm GAA node as the likely reason.
Leaked benchmark figures paint a striking efficiency gap
According to a tip shared on X by leaker @SPYGO19726, the Exynos 2600 reportedly drew just 7.6W in Geekbench 6 multi-core and 3.6W in single-core runs. By comparison, the A19 Pro was previously measured at about 12.1W in the same multi-core test. That shift translates to roughly a 59% improvement in reported performance-per-watt in the multi-core workload if the numbers hold up.
- Geekbench 6 single-core: ~3.6W (rumored)
- Geekbench 6 multi-core: ~7.6W (rumored)
- GFXBench GPU run: ~5.4W (rumored)
- Previous Exynos 2400 vs 2600: ~30% uplift in performance-per-watt (leaked comparison)
Why 2nm GAA could matter
Samsung's move to a 2nm gate-all-around (GAA) process is being credited for much of the reduced leakage and lower sustained power draw. GAA architectures wrap the transistor gate more completely around the channel, helping to reduce leakage currents and improve efficiency at the same operating points. If these prototype readings are accurate, the Exynos 2600 would be a clear example of silicon-level gains translating to real-world benchmark efficiency.
Not all that glitters is verified
It’s important to stress these figures are still rumors based on prototype runs. The leaker noted that leaks can change without notice, and independent corroboration is limited. Prototype thermals, benchmarking setups, power-rail instrumentation, and unfinished firmware can all skew results. That means retail chips and finished devices may show different behavior.
How the Exynos 2600 stacks up against rivals
Earlier comparisons placed Apple’s A19 Pro ahead of Qualcomm’s Snapdragon 8 Elite Gen 5 and MediaTek’s Dimensity 9500 on performance-per-watt, thanks to a 12.1W multi-core board draw. The Exynos 2600’s rumored 7.6W multi-core figure would flip that dynamic if confirmed, giving Samsung a compelling efficiency narrative. GPU numbers leaked for GFXBench also suggest lower GPU power use, which could help sustained gaming and thermal throttling in future devices.
Ultimately, the industry will want to see commercial silicon running production firmware in retail devices before updating rankings. For now, the Exynos 2600 leak highlights how advanced process tech like 2nm GAA can reshape expectations around mobile power efficiency — but treat the numbers as promising hints, not final proof.
