- sbx320 9y agoFrom the Spectre paper: > We have also verified the attack’s applicability to AMD Ryzen CPUs.
- lettergram 9y agoWe know that the scariest attack "meltdown", cannot be reproduced on AMD or ARM chips at all[1]. The second attack "Spectre" is also greatly mitigated due the neural network predicting pathways for the application. Thus it's unlikely/less-likely that you'll be able to access other locations in memory[2]. However, it's definitely possible.
