Allow me to summarize x86 side channel attacks: Spectre v1: speculation is insecure by design Spectre v2: secure branch prediction matters Meltdown: Intel are dumbasses L1TF: Intel are monumental, inexcusable dumbasses PortSmash: hyperthreading is insecure by design

yeah. full cores are better than hyperthreading. Maybe it would be useful to simplify the cpu architecture that more cores fit on a die
