AMD unveils new generation of Epyc, Instinct chips
To that end, AMD has launched the MI325X with greater memory capacity and bandwidth than the Instinct MI300X, which launched last December. The MI325X is based on the same CDNA 3 GPU architecture, compared with 192GB of HBM3 high-bandwidth memory and 5.3 TB/s in memory bandwidth in the MI300X.
AMD said AI inference performance in the MI325X provides 40% faster throughput with an 8-group, 7-billion-parameter Mixtral model over Nvidia’s top-of-the-line Hopper H200, 30% lower latency with a 7-billion-parameter Mixtral model, and 20% lower latency with a 70-billion-parameter Llama 3.1 model.
AMD is planning an eight-node platform for next year, similar to Nvidia’s DGX Pods. With eight MI325X GPUs connected over AMD’s Infinity Fabric, the platform will offer 2TB of HBM3e memory, 48 TB/s of total memory bandwidth, 20.8 petaflops of FP8 performance, and 10.4 petaflops of FP16 performance, AMD said.
The MI325X will begin shipping in systems from Dell Technologies, Lenovo, Supermicro, Hewlett Packard Enterprise, Gigabyte, and several other server vendors starting in the first quarter of next year, the company said.
