With all the hardware "security" issues discovered in the last few years, CPU designers should provide the possibility to turn off many of hardware features to end up with a brutal in-order basic CPU.
Performance will be destroyed for somewhat more confidence in their "security".

- Dalewyn 2y agoSounds like modern software is broken.
