Microsoft’s Windows and foreign database programs also sidelined as Beijing favours Chinese hardware and software
Among the 18 approved processors were chips from Huawei and state-backed group Phytium. Both are on Washington’s export blacklist. Chinese processor makers are using a mixture of chip architectures including Intel’s x86, Arm and homegrown ones, while operating systems are derived from open-source Linux software.
Substantially. CISC vs RISC is night and day. Keeping x86 for so long was a mistake, but one that generated billions in value for shareholders.
Oh I love it when shareholders get their value!!
But the manufacturing is still an issue.
If I can ask, if we go way back like 40 or 50 years ago, why did cisc get adopted over risc?
Cisc was never adopted. It all started out basic, then they gradually added more and more shit until you had a complex CPU.
Without the concept of risc there wouldn’t be a cisc.
Additionally to the other answer: the reason CISC came up to be was “less instructions”. Memory was a lot more expensive, and developers worked in assembly a lot more. So, less instructions made a lot of sense. Now, memory is cheap, and developers almost never write assembly unassisted.
