RISC vs. CISC Is the Wrong Lens for Comparing Modern x86, ARM CPUs

Try to investigate the differences between the x86 and ARM processor families (or x86 and the Apple M1), and you'll see the acronyms CISC and RISC. It's a common way to frame the discussion, but not a ...

RISC vs CISC: What's the Difference?

A new study comparing the Intel X86, the ARM and MIPS CPUs finds that microarchitecture is more important than instruction set architecture, RISC or CISC. If you are one of the few hardware or ...

RISC-V: Why The ISA Battles Aren’t Over Yet

A computer processor uses a so-called Instruction Set Architecture to talk with the world outside of its own circuitry. This ISA consists of a number of instructions, which essentially define the ...
