>> i.e. how does it perform on recent AMD systems?
Sorry for the latency. Recent AMD is reported by Enrique Nissem to not be vulnerable to the prefetch attack. TSX attack doesn't apply to AMD. Hund, Willems & Holz wrote in 2013 that AMD was vulnerable to that attack. The BTB is almost surely working in a different manner of fashion if at all. So AMD may or may not be vulnerable to the DPF attack, but none of the modern attacks should work - at least out of the box.
Best regards,
Anders
