The bug allows attackers to swipe data from a CPU’s registers. […] the exploit doesn’t require physical hardware access and can be triggered by loading JavaScript on a malicious website.
does this kind of report make people less likely to go with an AMD cpu?
I doubt it, since Intel has its share of similar CPU security issues. For several generations the understanding has been that Intel’s CPUs arrive with impressive performance on day 1, then gradually leak that performance away as security issues are patched over subsequent months.
