content: intel has fancier readahead and fancier speculative execution, using 3 times more wasted parallel computation of which 2/3rds of branch prediction unused by design. It increases single core speed, increases heat, increases electricity, but wins benchmarks.  AMD only has one ship design it keeps reusing the last 3 years, but makes it smaller and smaller, and mainly works on cache ram control (L3 cache, l2 cache).
