If you like specs gossip with a side of engineering context, here’s a fresh little scoop: noted Samsung leaker Ice Universe posted on X that the upcoming Galaxy S26 Ultra will use 10.7Gbps LPDDR5X RAM — the same memory family Samsung has been shipping, but at a higher transfer rate than the current Ultra.

LPDDR5X is the low-power DRAM standard vendors use in flagship phones. Samsung and other DRAM makers have been rolling out faster LPDDR5X bins: the family includes chips at roughly 8.5Gbps and newer parts at 10.7Gbps (Samsung has publicly discussed 10.7Gbps parts). Moving from ~8.5Gbps to 10.7Gbps is a nontrivial bandwidth increase — better for heavy multitasking, high-bitrate media work, and on-device AI workloads that need fast scratch memory.

Samsung’s Ultra models haven’t always chased headline RAM sizes every year; instead, the company tends to upgrade silicon, memory speed, camera hardware, and software features incrementally. The hint that the S26 Ultra would use 10.7Gbps LPDDR5X suggests Samsung is prioritizing memory bandwidth and efficiency rather than just advertising larger GB numbers. That can matter for things like on-device AI, where throughput and latency are often more important than raw GBs.

That said, the leak did not specify whether Samsung will change RAM capacity (12GB, 16GB, etc.), and several earlier Ultras have shipped with the same nominal capacities across multiple generations.

A quick market reality check: a number of recent Android flagships have moved toward 16GB as a common baseline, and some experimental or luxury models push to 24GB. For example, Xiaomi’s Ultra flagships have been offered with 16GB LPDDR5X configurations, and OnePlus and other OEMs have likewise been shipping 16GB base variants (with higher top-end options). Google’s Pixel 10 Pro leaks also point to Pro models with 16GB in the lineup. So even if Samsung elects to keep, say, 12GB as a baseline, it may look less aggressive on paper compared to some rivals — unless it pairs the capacity with significantly faster memory or software tricks that reclaim RAM more efficiently.

If you want to see extreme examples, there are phones that max out at 24GB, but those remain niche and are mostly about spec-showing rather than everyday benefits for most users.

So — should you worry if Samsung keeps 12GB?

Short answer: probably not, for most users. In real life, 12GB is ample for 99% of daily tasks — browsing, social, camera work, gaming, and even serious multitasking. Where more RAM helps is in edge cases: extremely long multitasking sessions with dozens of heavy apps, professional workflows on phone (big raw photo editing, on-device AI processing), or when brands use features like extensive app snapshotting to keep many apps instantly resumable.

But if Samsung keeps capacity conservative while moving to 10.7Gbps LPDDR5X, the user experience could still feel snappier because the phone can move data to and from memory faster. It’s the difference between a wider, faster lane versus simply adding more lanes that you don’t fill.

Why Samsung might focus on speed

Two likely reasons:

1. On-device AI — Faster memory directly benefits inference latency and throughput for models running locally. Samsung has been leaning into AI features, and higher memory bandwidth helps those features run smoothly.
2. Power efficiency — Newer LPDDR5X parts often improve perf-per-watt; a faster chip that’s also more efficient can be a net win for battery life under load.

If Ice Universe is right, the S26 Ultra won’t be a radical reinvention in RAM type — it’s still LPDDR5X — but it will probably use a faster 10.7Gbps bin that improves bandwidth and on-device AI performance. Whether Samsung pairs that with bigger RAM capacities is the next, more relevant question for buyers who like big numbers on spec sheets. Until Samsung confirms the full spec sheet, the smarter move for most people is to watch for official distinctions (bandwidth and capacity) rather than fixating on a single GB figure.
