That doesn't make a ton of sense to me. Aren't mainframe CPUs developed using modern techniques?

- JdeBP 9y agoActually, mainframe CPUs are developed using old techniques, which are all of a sudden interesting again. (-: See for starters this discussion about reinventing the AS/400: https://news.ycombinator.com/item?id=16053518 https://news.ycombinator.com/item?id=16053518
- blattimwind 9y agoAt least some time ago IBM mainframes were powered by their regular POWER processors "just" with modified/extended microcode. Though it seems they also have dedicated CPUs for them, like the zEC12. (POWER doesn't really qualify as "old techniques")
