HOW DID AMD RYZEN GET 50% FASTER IN TWO YEARS?

Summary from the TLDR Dev newsletter

AMD's Ryzen 7 9800X3D posts 47% higher single-core and 58% higher multi-core Geekbench 6 scores than the 5800X3D from two years earlier, despite only a 15% boost-clock increase. The gain comes from wider execution, larger caches and reorder buffers, more integer units, and a shift from 256-bit to 512-bit SIMD.
