Intel proposes x86S, a 64-bit CPU microarchitecture that does away with legacy 16-bit and 32-bit support

Intel has released a whitepaper outlining a way to simplify its CPU architectures by removing legacy 16-bit and 32-bit support, therefore making them 64-bit only. Intel believes this change will lead to better optimized processors, meaning better performance and efficiency.

The building blocks of Intel’s processor range can be traced all the way back to the original 16-bit 8086 processor released in 1978. Rather than include support for decades-old software and operating systems, Intel believes virtualization technologies have developed enough to emulate the features required for legacy systems. It’s saying it’s time to move on.
