Finding a CPU Design Bug in the Xbox 360 (2018)

Wow... A speculative branch prediction path actually get's preemptively executed despite the branch outcome? No matter if the execution has side-affects??? That's quite amazing. Are modern CPUs doing speculative execution like this and just put extra safeguards around affects or do they just prefetch / decode instructions now-a-days?

It is interesting that IBM dominated this generation of consoles, and was vanquished in the next.

The high failure rates of the Xbox 360 did not help.

Would need "(2018)" in the title.
