   Elegance is for tailors:-)   
      
   If you look at RISC-V (e.g. the instructions in RV64GC), it shows a   
   certain minimalism compared to its competitors AMD64 and ARM A64.   
   That also shows in the size of the RISC-V manual compared to the   
   manuals of its competitors.

   The Pentium 8505 is an Alder Lake U with half of it's P-cores and half   
   of its E-Cores disabled, and some of the cache, leaving 1 P-Core and 4   
   E-cores.  If you want the best performance, there are certainly a   
   number of microarchitectures by AMD, Apple, ARM, Intel, and Qualcomm   
   that compete for that spot and show fascinating feats in clock rate   
   and instructions per cycle (IPC), and the cores in the Pentium 8505   
   are not far behind; newer microarchitectures are better.  If you want   
   something small, maybe look for the ARM Cortex M0 or one of the small   
   RISC-V cores.
