A lot of systems are “good enough” and run flawlessly for years/decades so unless you have a good business case you won’t be able to move from x86 to ARM or the new RISC open stuff because the original system cost a couple million dollars.

- ajross 2y agoThat was true through the 90's, but not anymore. A typical datacenter unit from 2014 would have been a 4-socket Ivy Bridge-EP with 32ish ~3 GHz cores. You aren't going to emulate that feasibly with equivalent performance on anything modern, not yet.
- snvzz 2y agoCycle exact? Sure. But what are the odds you need that for some x86 software made in 2014. Otherwise, via translation techniques, getting 80% of native performance isn't unheard of. Which would be very fast relative to any such Ivy Bridge server. Transitioning away from x86 definitely is feasible, as very successfully demonstrated by Apple.
