US chipmaker AMD advised customers last week to disable a new performance feature if they plan to use CPUs for sensitive operations, as this feature is vulnerable to Spectre-like side-channel attacks. Called Predictive Store Forwarding (PSF), this feature was added to AMD CPUs part of the company's Zen 3 core architecture, a processor series dedicated to gaming and high-performance computing, which launched in November 2020. The feature implements a technique called speculative execution, which works by running multiple alternative CPU operations in advance to make results available faster, and then discarding "predicted" data once deemed unneeded.
