This results in HBF packing 8 to 16 times more capacity per stack than today’s HBM implementations.
This enables the high bandwidth while maintaining NAND’s cost and capacity advantages.
Of course, NAND’s Achilles heel has always been higher latency compared to DRAM technologies such as HBM.
Aspointed outby Tom’s Hardware, HBF is no different and obviously doesn’t match DRAM’s blazing speeds.
Tasks like gaming are off the table.
There are still some hurdles for the technology to clear.
We also don’t know what kind of bandwidth numbers HBF can hit.
Despite the remaining questions, it seems SanDisk sees big potential.
The company wants HBF to be an open standard complementing HBM in hardware like GPUs.
Eventually, SanDisk even sees the tech filtering down from high-end AI systems to consumer devices like smartphones.
