AMD sells CPUs with 4.2+ GHz that can be easily overclocked (like Intel CPUs from 15+ years ago). We are now at 12nm whereas we had &gt;90nm years ago. Increasing the clock speed is certainly possible, but always a tradeoff. We can always put the CPU in a specific oil like the Cray2. If x86&#x2F;64 is the limiting factor, they could release an incompatible CPU architecture (like the failed Itanium or like ARM). A lot of the die space on current CPUs is internal memory (L1, L2). It&#x27;s pretty easy to draw the &#x27;conspiracy&#x27; card.
