Semi Doped NVIDIA's Marvell Strategy, Is Memory Different This Time?, Intel's Ireland Fab
11 snips
Apr 3, 2026 A deep dive into NVIDIA's $2B tie-up with Marvell and what it might mean for AI interconnects and multi-vendor racks. A lively debate on whether NVLink could become the dominant scale-up standard or if multiple protocols will persist. A look at the sharp DRAM and NAND price surge and how AI, new LPDDR buyers, and long-term contracts are reshaping memory markets. Analysis of Intel repurchasing its Ireland fab and the strategic signals behind the buyback.

Episode notes
NVIDIA Buying Influence Over The Interconnect
- NVIDIA's $2B investment in Marvell is less about funding a compute rival and more about locking in interconnect and platform control.
- NVLink Fusion gives NVIDIA a way to embed its interconnect into multi-vendor racks and influence which silicon ecosystems customers deploy.
NVLink Could Become Optical With Photonic Fabrics
- Marvell's Celestial acquisition and focus on silicon photonics implies NVLink could migrate from copper to optical physical layers.
- NVLink as a protocol can work over optics, enabling die-to-die photonic fabrics for GPUs, XPUs, and HBM connections.
Customer Pull Is Driving Multi Vendor NVLink Adoption
- NVIDIA appears to be enabling heterogeneous racks: XPUs and NVIDIA GPUs can co-exist and communicate over NVLink Fusion.
- AWS Tranium's use of NVLink and Marvell's partnership suggests customer pull (AWS) drove the collaboration to ensure interoperability at scale.
