AMD unveils AI processor, looks to challenge Nvidia
AMD is coming for Nvidia’s AI crown in a big way with the launch of its new Instinct processor, which it claims can do the work of multiple GPUs.
CEO Lisa Su called the Instinct MI300X “the most complex thing we’ve ever built.” She held up the chip, which is about the size of a drink coaster, at an event on Tuesday in San Francisco.
Weighing in at 146 billion transistors, the MI300X comes with up to 192GB of high-bandwidth HBM3 memory shared by both the CPU and GPU. It has a total of 13 chiplets on the die. The chip also has a memory bandwidth of 5.2 TB/s, which is 60% faster than Nvidia’s H100.
The chip consists of Zen CPU cores and AMD’s next-generation CDNA 3 GPU architecture. The enormous amount of memory is the real selling point, according to Su.
