Does RISC Vs. CISC Still Matter In The Apple M1 Ultra Era?

“x86 vs. ARM” doesn’t necessarily mean “CISC vs. RISC” around 2022. This was true decades ago, but over the years the terminology has become ambiguous in the two ISAs, borrowing technology from each other. Many commentators believe that, despite their names, RISC and CISC stand for more than the simplicity or complexity of instruction sets, and the term is best suited to chronology of history. Others believe that RISC and CISC are fundamentally different and the two will never meet.

However, the former view is gaining ground day by day. According to this school, microprocessors have advanced so much in the past few decades that terms like RISC and CISC are a thing of the past. There are also certain differences between the two sets of instructions. For example, some characteristics of the RISC instruction set make it more efficient than x86, including the use of fixed-length instructions and a load/store design. If so, of course. RISC vs CISC The debate continues, and the answer to whether there are still differences in modern times depends on who you ask.

Does RISC Vs. CISC Still Matter In The Apple M1 Ultra Era?

It is important to note that ‘x86 vs. ARM’ doesn’t necessarily translate to ‘CISC vs. RISC’ circa 2022. While it might have been true a few decades ago, the terms have become more ambiguous over the years with both ISAs borrowing technologies from each other. Many commentators believe that despite their names, RISC and CISC are much more than just the simplicity or complexity of an instruction set, and the terms are best consigned to the annals of history. Yet others believe that RISC and CISC are fundamentally different, and the two shall never meet.
However, the former viewpoint is becoming increasingly more accepted with each passing day. According to this school of thought, microprocessors have evolved so much over the past decades that terms like RISC and CISC have become relics of the past. The two instruction sets, meanwhile, continue to have specific differences. For example, some of the characteristics of RISC instruction sets make them more efficient than x86, including the use of fixed-length instructions and a load/store design. No wonder then that the RISC vs. CISC debate rages on and the answer to whether any difference between them still exists in modern times depends on who you ask.
