H2 2026
The AMD Instinct MI440X is the entry-level member of the MI400 series, built on the CDNA 5 architecture. It is expected to share the series' 432 GB HBM4 / 23.3 TB/s memory configuration, differentiated by workload focus rather than memory capacity.
Positioned for cost-optimized AI inference, the MI440X rounds out AMD's MI400 lineup (MI455X, MI450X, MI430X, MI440X) against the NVIDIA B300 generation. QS Compute can source MI440X accelerators — contact us for pricing and availability.
