Samsung puts compute units inside 16GB LPDDR5X memory chip, achieving 614 GB/s internal bandwidth—8x faster than external pins—to accelerate AI inference by processing data where it's stored instead of moving it.

Processing in Memory: DRAM Is About to Do Math

At Hot Chips 2026, Samsung presented a 16 GB LPDDR5X memory package that delivers 614 GB/s of internal bandwidth to its own compute units. For scale, 614 GB/s matches the memory bandwidth of a top-spec Apple M5 Max across its entire unified memory system: the 40-core GPU configuration in the $3,499 MacBook Pro. Samsung claims that number from inside one memory package, against the 76.8 GB/s that escapes through its external pins. Tom's Hardware reported the resulting eightfold difference. That e...
