Intel's CPUs Are Failing, ft. Wendell of Level1 Techs

  Intel problem is that they keep pushing extensions race while AMD proved with their Ryzen series that if you keep your instruction set to a minimum, then your CPUs will be energy efficient, even arm proved this by pushing extensions too far like intel and getting overheating chips

    The overhead of additional instructions isn’t the issue, they often translate those instructions into a smaller set of actual operations. It’s not like they have a special circuit for every instruction, a lot of instructions translate to a pipeline of multiple, modular circuits.

    The actual silicon will look more like ARM despite having a very large difference in instruction set sizes.

      Then why AMD is more efficient then intel and arm nowadays?

    This isn’t true anymore, Intel dropped AVX512 since they moved to Big+Small cores design while AMD actually implemented it with Zen 4.

      Does AMD just keep winning or what? I just don’t want CPU’s with a 500 Watt tdp.

    Both intel and AMD are running the same instruction set though are they not? (Cross licensing x86/x64)

      Look up gcc x86 options, intel have twice as big instruction set, and with expansion of instructions of arm, risc architecture ain’t saving it from overheating now because of aforementioned, now bloated instruction set
