AMD announced plans during its Financial Analyst Day 2025 to release the Instinct MI400 series accelerators in 2026 and the MI500 series in 2027, positioning both product lines against competitors in the artificial intelligence computing market. The MI400 family will feature CDNA 5 architecture with two variants: the MI455X targeting training and inference applications, and the MI430X designed for high-performance computing workloads.
The MI400 series will deliver 40 petaflops of FP4 performance and 20 petaflops of FP8 capability, doubling the computational power of its MI350 predecessor while incorporating 432 gigabytes of HBM4 memory with 19.6 terabytes per second bandwidth. AMD claims the MI400 offers 1.5 times greater memory capacity and scale-out bandwidth compared to competing platforms.
The company confirmed it will maintain annual release cycles for datacenter accelerators through 2027, when the MI500 generation arrives with advanced compute, memory, and interconnect technologies.
