> Featuring an 8-wide decode block, Apple’s Firestorm is by far the current widest commercialized design in the industry. Other contemporary designs such as AMD’s Zen(1 through 3) and Intel’s µarch’s, x86 CPUs today still only feature a 4-wide decoder designs This is one place where the 64-bit ARM ISA design shines: since all instructions are exactly 4 bytes wide and always aligned to 4 bytes, it's easy to make a very wide decoder, since there's no need to compute the instruction length and align the instruction stream before decoding.
