AMD Instinct MI350P Overview: HBM3E Memory in a PCIe Gen5 Card

AMD Instinct MI350P brings HBM3E memory to a dual-slot PCIe Gen5 form factor, offering data centers a new option for running AI models. I explain its specifications, design decisions, and how it lines up against competing PCIe GPU solutions.

■ Key Specifications and Design
- 144GB HBM3E, up to 4TB/s peak memory bandwidth, PCIe Gen5 x16
- New numeric formats (MXFP8, MXFP6, MXFP4) and dedicated hardware video decode
- 600W in dedicated GPU servers, adjustable down to 450W in conventional chassis
- Passive cooling, double-wide full-height/full-length, MIG-style partitioning
- Effectively a half-configuration of MI350X, without Infinity Fabric expansion

■ Market Position and Comparisons
- Competing options in the PCIe Gen5 segment: Nvidia H100/H200 NVL and RTX Pro 6000 Blackwell
- Memory capacity and bandwidth differences across eight-GPU servers
- Systems displayed at Computex, Dell Tech World and HPE Discover
- Power, rack and deployment constraints for inference-focused environments

For data center operators, AI practitioners and hardware enthusiasts comparing options below rack-scale systems, this breakdown provides a concrete basis for evaluating specifications, memory limits and deployment scenarios before deciding what to run in your own environment.
