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.

I thought the design flaws of the Xbox 360 cooling system had more to do with Microsoft than any inherent design flaw by IBM. I assumed that switching to x86 processors let Microsoft leverage their native developer tools from Windows which helped developers.

Would need "(2018)" in the title.

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?

unrelated, but recently XBox One was hacked for the first time
