Will HBM let AMD unseat Nvidia?

AMD will rely on advancements in high-bandwidth memory (HBM) in its bid to unseat Nvidia as the industry leader for making the components that power generative AI systems.

Building on the theme of processor-in-memory (PIM), Xilinx, which is owned by AMD, showcased its Virtex XCVU7P card, in which each FPGA had eight accelerator-in-memory (AiM) modules. The firm showcased this at OCP Summit 2023, alongside SK Hynix’s HBM3E memory unit, according to Serve the Home.

Essentially, by performing compute operations directly in memory, data won’t need to move between components on systems, meaning performance increases and the overall system becomes more energy efficient. Using PIM, with SK Hynix’s AiM, led to ten times shorter server latency, five times lower energy consumption, and half the costs in AI inference workloads.

## The latest twist in the ongoing AI arms race

Nvidia and AMD make most of the best GPUs between them, and one may assume that efforts to improve the quality of these components are key to improving AI performance. But it’s actually by tinkering with the relationship between compute and memory do these firms see there are huge advantages to be made in power and efficiency.
