AMD announces AI roadmap through 2026
AMD has unveiled an expanded AMD Instinct AI accelerator roadmap, including the AMD Instinct MI325X accelerator, planned to be available in 4Q24, the MI350 and the MI400.
The announcement was made by Lisa Su, CEO and chair of AMD, in a keynote at the Computex exhibition in Taiwan, Taipei. Su also announced the AI300 series of AI-enabled processors for laptop PCs and the Ryzen 9000 series of processors for desktop PCs.
The Instinct MI325X accelerators provide 288Gbytes of HBM3E. The follow up MI350, based on the CDNA-4 architecture, is expected in 2025. This is expected to provide 35x AI inference performance compared with the MI300 series based on the CDNA 3 architecture.
A further upgrade of the CDNA architecture will be used with the MI400 series accelerators planned for 2026, Su said.
The MI300 series processors are aimed at TSMC’s 6nm/5nm manufacturing process. The MI325 supports a model size of over a trillion parameters which gives it a 2x advantage over H200, Nvidia’s leading AI accelerator chip, Su said.
Su did not provide details of what manufacturing process technology nodes the other processor series are targeting. MI325 will likely be on the 6nm/5nm or 4nm. This would likely put the MI350 due in 2025 on 3nm process with the MI400 possibly yet to be decided.
