AMD Instinct MI300 revealed: the world’s first chiplet-based CDNA 3 accelerator with over 140 billion transistors

We have already discussed in detail the next AMD premieres that were presented during the CES 2023 conference: about AMD Ryzen 7000X3D desktop processors with 3D V-Cache, the new generation of Ryzen 7040 and Ryzen 7045 mobile APUs, as well as mobile RDNA 3 graphics in the form of Radeon RX 7000M and Radeon RX 7000S. At the end of the presentation, however, a real “firecracker” was left in the form of the first announcement of the Instinct MI300 graphics accelerator, based on the CDNA 3 architecture. A real behemoth is being prepared among the systems intended for the HPC and AI markets.

At the CES 2023 conference, AMD first announced the Instinct MI300 graphics accelerator, based on a chiplet APU design and equipped with an impressive 146 billion transistors.

During CES 2023, we learned the first details about the Instinct MI300 graphics accelerator, which will be the first APU for the HPC / AI market, using not only CPU cores, but also advanced 3D packaging technology with many different chiplets. The Instinct MI300 accelerator will consist of 24 Zen 4 cores (adapted to servers) and a graphics chip based on the CDNA 3 architecture in a chiplet design. The entire accelerator is to have 146 billion transistors on board, and two technological processes were used for production: TSMC N5 and TSMC N6.

The AMD Instinct MI300 graphics accelerator will also be equipped with 128 GB of HBM3 memory on an 8192-bit bus. The system is to offer up to 8 times higher performance in AI calculations compared to the Instinct MI250X model, based on the CDNA 2 architecture. The performance per watt ratio itself is to increase up to five times. The AMD Instinct MI300 accelerator will be ready in the second half of the year, and the sampling process for the company’s first customers is now beginning.
