AMD Instinct MI400 with 2nm XCD dies

During an interview with Yahoo Finance, AMD CEO Dr. Lisa Su confirmed that the company’s next-generation data center GPU, the Instinct MI450, will be its first accelerator to use 2nm process technology. The new architecture is set to launch next year.

The interview followed AMD and OpenAI’s announcement of a new partnership, which will see OpenAI deploying MI450 chips next year.

We are very excited about our MI450 generation. It has 2nm technology, the most advanced fabrication capability”.

— AMD CEO Lisa Su

The TSMC N2P (2nm) node is reportedly used only for the XCD (Accelerator Core Die), while the AID (Active Interposer Die) and MID (Media Interface Die) are based on TSMC’s N3P process, this was detailed further by known leaker Kepler_L2 .

AMD has been working on high-performance chips using TSMC’s 2nm technology for some time. Dr. Su previously presented a wafer for the next-generation EPYC “Venice” processors back in April. However, the Instinct MI450 chips are expected to be larger and more complex to manufacture.

The MI450 will compete with NVIDIA’s Ruby-generation AI accelerators, which use TSMC’s 3nm (N3P) process. AMD claims to offer similar FP4/FP8 compute speeds to Vera Rubin (Oberon), but will offer 1.5x the memory capacity and bandwidth.
