Galaxy S26 RAM vs S25 RAM is a hot topic for Samsung fans right now. On paper, the S26 Ultra’s memory gets a solid upgrade, moving from Micron’s 1β LPDDR5X to the newer 1γ LPDDR5X, pushing speeds from 9.6 Gbps to an industry-leading 10.7 Gbps.
I’ve looked closely at Micron’s 1γ LPDDR5X RAM, and it’s a step up from last year’s 1β version. We’re talking 10.7 Gbps speeds vs 9.6 Gbps on the S25 Ultra — the kind of boost that can shave seconds off big app loads and make AI tools respond faster. But here’s the big question: will you actually notice the difference, and is it worth upgrading for RAM alone? Let’s break it down.
Galaxy S26 RAM Overview
Samsung’s Galaxy S26 Ultra is set to feature Micron’s 1γ (1-gamma) LPDDR5X RAM, boasting speeds of 10.7 Gbps — the fastest in the smartphone industry right now.
- Type: LPDDR5X (1γ process)
- Speed: 10.7 Gbps
- Capacity: 12 GB (unchanged since Galaxy S20 Ultra in 2020)
- Efficiency: Up to 20% better power usage compared to the S25 Ultra
- Size: Just 0.61 mm thick, freeing up space for a potentially larger battery or improved camera sensor
This faster RAM is particularly beneficial for AI-driven tasks, heavy multitasking, gaming, and data-heavy applications.
Galaxy S25 RAM Overview
The Galaxy S25 Ultra, launched in early 2025, also came with LPDDR5X RAM, but on Micron’s 1β (1-beta) process.
- Type: LPDDR5X (1β process)
- Speed: 9.6 Gbps
- Capacity: 12 GB
- Efficiency: Standard power management for its generation
While the S25 Ultra is still a performance powerhouse, the new S26 Ultra aims to refine that experience with more speed and efficiency.
Galaxy S26 RAM vs S25 RAM – Key Differences
| Feature | Galaxy S26 Ultra RAM | Galaxy S25 Ultra RAM |
| Type | LPDDR5X (1γ) | LPDDR5X (1β) |
| Speed | 10.7 Gbps | 9.6 Gbps |
| Capacity | 12 GB | 12 GB |
| Power Efficiency | 1Up to 20% better | Standard for 2025 |
| Chip Size | 0.61 mm (smaller) | Larger footprint |
Real-World Performance Impact
The jump from 9.6 Gbps to 10.7 Gbps may sound small on paper, but it can make a difference in:
- AI processing speed – Faster responses and better handling of generative AI features.
- App loading times – Especially with large games and productivity apps.
- Multitasking – Smoother switching between apps without reloading.
- Battery life – The 20% power efficiency gain means less battery drain during heavy use.
However, the capacity remains 12 GB — a point where Samsung lags behind rivals like Xiaomi, OnePlus, and Google, who now offer 16 GB as standard on their flagships.
Should You Upgrade from S25 Ultra to S26 Ultra for RAM?
If you’re upgrading purely for RAM performance, the S26 Ultra offers:
- Faster memory speeds for improved performance
- Better efficiency for battery life gains
But it does not increase the RAM size, which means if you were hoping for 16 GB, you’ll be disappointed.
If you use your phone for intensive AI, gaming, or productivity work, the speed boost could be worth it. But for everyday tasks, the difference between Galaxy S26 RAM vs S25 RAM may feel minor.
Final Thoughts – Galaxy S26 RAM vs S25 RAM
The Galaxy S26 Ultra’s RAM is undeniably faster and more efficient than the Galaxy S25 Ultra’s RAM, thanks to Micron’s 1γ LPDDR5X tech. But with the same 12 GB capacity, it’s an evolutionary upgrade rather than a revolutionary one. Power users will appreciate the refinements, but average users may find the S25 Ultra still more than capable.
