How the 8086 processor's microcode engine works
NEC did their own independent line of x86 clones. Apparently NEC V33 is 8086 with "instruction decode done by hardwired logic rather than a microprogrammed control store. Throughput is twice as high as a V30" (datasheet claims four times faster). V30 was their clean room RE 8086 clone and was already 10-30% faster than original.V33 was used in PC-98 DO+, and in SOC form (NEC V53) in legendary Akai MPC3000, probably because Roger Linn's original LM-1 and LinnDrum were also full x86 PCs with custom cards.Sadly I cant find any place that sells V33/V53, maybe could be sourced in Japan.
