AI acceleration blocks. AMD CPUs

AMD’s CFO, Jean Hu, at the Barclays technology conference, discussed the expansion of CPUs with integrated AI acceleration blocks. Currently available in the mobile segment, Hu predicts these processors will significantly impact the PC market by 2025. The upcoming year isn’t expected to see substantial growth in PC market volume, with only a marginal increase anticipated. Factors like the end of support for an older Windows version may boost demand for new PCs. However, AMD, unlike Intel, Dell, and Lenovo, which link hopes of market revival to 2024, adopts a more conservative stance regarding the influence of AI-accelerated processors on the PC market.
