AMD's Instinct MI325X accelerator will feature 288GB of HBM3E memory with 6TB/s of memory bandwidth. The MI325X continues to rely on the CDNA 3 architecture. AMD is talking up 1.3x better compute performance than the competition for the Instinct MI325X.
With the AMD Instinct MI350 series in 2025, AMD is aiming for up to a 35x increase in AI inference performance over current Instinct MI300 series hardware. AMD CDNA 4 is promising big gains over CDNA 3 but in the advanced briefings around their Instinct plans they were light on not revealing too many architectural details.
Meanwhile in 2026, AMD will introduce the Instinct MI400 series built atop the CDNA "Next" architecture.
AMD is committing to an annual roadmap for the Instinct accelerators as it ramps up competition against NVIDIA while also concurrently working on more software improvements too for ROCm and related software components.
