Nvidia custom ‘NVHBM’ promises 30% higher bandwidth, 15% lower power than commodity HBM4e — custom base die and PHY will be available to NVLink Fusion partners

But these are, as of now, reasons for Nvidia’s prospective partners to consider incorporating NVLink Fusion and NVHBM into their custom designs, not benefits that will materialize in the Rubin rack-scale systems already …

Hot Chips 2026: High Bandwidth Flash promises massive bandwidth and capacity, but its usability is extremely limited — new memory format strikes a balance betwe

Additionally, more local capacity could also reduce communication between accelerators. Conventional expert parallelism distributes experts across GPUs and requires all-to-all communication at every layer. OXMIQ claims t…

Hot Chips 2026: Arm details AGI server CPU with two 70-core N3P chiplets — touts 2 TB/s UCIe fabric link and 12-channel memory controller

The important point is that CMN-S3 is not just an internal CPU mesh, as Arm designed the coherent system to extend outside of the die to extend coherency beyond the die and the socket. The approach is conceptually closer…

Hot Chips 2026: Micron warns HBM wafer penalty is widening with every generation — AI memory uses 3x more silicon than DDR5, company says memory wall is ‘gettin

Micron’s presentation put compute performance scaling at roughly three times every two years and HBM bandwidth at under two times, a divergence Sreeramaneni summarized by saying “the memory wall is still present, and, in…
