As AI agents and trillion-parameter workloads become mainstream, the performance of AI infrastructure depends not only on compute, but on how compute, memory, storage, networking and software are designed together as a unified system. To help hyperscalers and AI innovators build the next generation of semi-custom AI infrastructure, NVIDIA today expanded NVIDIA NVLink Fusion with NVIDIA NVHBM , a next-generation high-bandwidth memory technology that brings higher memory performance and efficiency to XPUs. It will be validated and offered by leading memory partners, extending this advanced memory capability to NVLink Fusion customers. Traditional HBM architectures place the memory controller on the XPU die, consuming valuable silicon area that could otherwise be dedicated to compute. NVHBM, built on the same technology that NVIDIA will use for future GPUs, integrates NVIDIA’s custom memory controller into the HBM base die. By integrating the memory controller into the 3D HBM stack instead of the XPU, NVHBM delivers up to 30%..."},"evidence_pages":[],"related_signals":[{"id":"0e43ef74-ed31-474b-bad1-c11c20d5a7ce","url":"https://onlylabs.fyi/signals/0e43ef74-ed31-474b-bad1-c11c20d5a7ce","source_url":"https://blogs.nvidia.com/blog/geforce-now-thursday-gamescom-2026/","title":"GeForce NOW Gives Gamers More Ways to Play at Gamescom 2026","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"nvidia","name":"NVIDIA","category":"frontier-lab"},"occurred_at":"2026-08-27T13:00:33+00:00","first_seen_at":"2026-08-27T16:00:52.900351+00:00","date_source":"rss.item_date"},{"id":"e403ce63-169f-4dc9-a1a9-41476f09aad5","url":"https://onlylabs.fyi/signals/e403ce63-169f-4dc9-a1a9-41476f09aad5","source_url":"https://blogs.nvidia.com/blog/vera-cpu-delivery/","title":"Delivering Vera: NVIDIA’s First CPU Built for Agents Is Shipping Now","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"nvidia","name":"NVIDIA","category":"frontier-lab"},"occurred_at":"2026-08-27T13:00:17+00:00","first_seen_at":"2026-08-27T16:00:52.900351+00:00","date_source":"rss.item_date"},{"id":"3c997b2a-6e74-41df-9c11-b01e7a5aaf37","url":"https://onlylabs.fyi/signals/3c997b2a-6e74-41df-9c11-b01e7a5aaf37","source_url":"https://blogs.nvidia.com/blog/gamescom-rtx-spark-pc-games-technology/","title":"Leading Publishers Bring Blockbuster PC Games and Technology to NVIDIA RTX Spark","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"nvidia","name":"NVIDIA","category":"frontier-lab"},"occurred_at":"2026-08-25T15:30:48+00:00","first_seen_at":"2026-08-25T16:01:46.043354+00:00","date_source":"rss.item_date"},{"id":"ec68aed5-7158-4662-a620-1d377fddfe1d","url":"https://onlylabs.fyi/signals/ec68aed5-7158-4662-a620-1d377fddfe1d","source_url":"https://blogs.nvidia.com/blog/nvlink-fusion-xpu-ai-factory/","title":"How XPUs Meet a World-Class AI Factory","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"nvidia","name":"NVIDIA","category":"frontier-lab"},"occurred_at":"2026-08-24T15:00:54+00:00","first_seen_at":"2026-08-24T16:01:51.041873+00:00","date_source":"rss.item_date"},{"id":"388609f2-9a21-4d5c-b4b5-ab675c8f2a5b","url":"https://onlylabs.fyi/signals/388609f2-9a21-4d5c-b4b5-ab675c8f2a5b","source_url":"https://blogs.nvidia.com/blog/vera-rubin-lpx-spectrum-x-nvlink-fusion/","title":"With Groq 3 LPX in Full Production, NVIDIA Extends Vera Rubin Inference for Agents","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"nvidia","name":"NVIDIA","category":"frontier-lab"},"occurred_at":"2026-08-24T15:00:41+00:00","first_seen_at":"2026-08-24T16:01:51.041873+00:00","date_source":"rss.item_date"},{"id":"caa5f973-9fdb-4b31-8896-bf84e8abaf6e","url":"https://onlylabs.fyi/signals/caa5f973-9fdb-4b31-8896-bf84e8abaf6e","source_url":"https://blogs.nvidia.com/blog/vera-rubin-nvl72-efficiency-ai-agents/","title":"Up to 30x More Work Per Watt: NVIDIA Vera Rubin NVL72 Sets a New Efficiency Standard for AI Agents","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"nvidia","name":"NVIDIA","category":"frontier-lab"},"occurred_at":"2026-08-24T15:00:19+00:00","first_seen_at":"2026-08-24T16:01:51.041873+00:00","date_source":"rss.item_date"}]}
