Intel has and has alwasy been a lousy CPU designer and maker.
The CPU desings and ISAs are a mess.
The procution and test aer hit too - they produce so much bug riddled junks that its a joke (I worked there).
The only thing that ahs allowed Intel lbundering incomeptnence is the ability to throw large dollops at monet at eerything - fabs, tests, chip designers, etc etc.
Intel will die a death without the free cash to throw at its fuckups.
