A new leak suggests Samsung’s upcoming Galaxy S26 lineup will continue using LPDDR5X RAM, but with a noticeable speed boost compared to last year’s models.
According to reliable leaker Ice Universe, the Galaxy S26 series is expected to feature 12GB LPDDR5X RAM across all variants. Samsung stopped offering 8GB options last year, so a 12GB baseline is likely for the entire S26 lineup.
While LPDDR5X isn’t new, the memory bandwidth on the Galaxy S26 models reportedly gets upgraded to 10.7 Gbps.
For comparison, the Galaxy S25 series capped out at 8.5 Gbps, even on their maxed-out 12 GB variants.
That makes LPDDR5X the fastest RAM currently shipping on mainstream mobile phones apart from the customized Ultra+ RAM used on the OnePlus 15.
Samsung usually sources its memory chips from Micron, so that may be what happens again with the S26 generation.
Fans hoping to see Samsung's next-generation LPDDR6 RAM in the S26 may have to wait longer.
Samsung's in-house LPDDR6 module offers the same 10.7 Gbps speed but with more I/O channels and a 21% better efficiency compared to Micron's version.
However, LPDDR6 isn't expected to debut until Consumers Electronic Show (CES) 2026, meaning it would miss the production window for the Galaxy S26 series.
If Samsung somehow manages to include LPDDR6, the technology is most likely to appear only on the Galaxy S26 Ultra variant with 16GB + 1TB, which usually goes to very limited markets. That makes the chances even slimmer.
For now, the safest bet is that the entire Galaxy S26 family will ship with 12GB LPDDR5X RAM at 10.7 Gbps.
