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 ...

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 vs. CISC wars raged in the 1980s when chip area and processor design complexity were the primary constraints and desktops and servers exclusively dominated the computing landscape. Today, energy ...

Prompted by the chipmaker's announcement of the SSE5 instruction-set extensions, Glaskowsky analyzes the ultimate outcome to this old controversy. Peter N. Glaskowsky is a computer architect in ...

A new instruction set by the original creator of MIPS aims to reinvent the ultra-low power, high-efficiency processor -- and to do so with an architecture that's fundamentally open and available to ...

Back in 1998, when I first began covering hardware at the newly launched Ars Technica, much of my writing focused on issues raised by the raging Mac vs. PC flame wars that took place in computing ...

Ten years ago, I waded into the then-raging “Mac vs. PC” wars with a lengthy treatise on “RISC vs. CISC: the Post-RISC Era.” In the conclusion to that article, I declared the “RISC vs. CISC” debate ...

Many of the differences between RISC-V, ARM, and x86 microprocessors are subtle and relate to how memory is addressed, branches are executed, exceptions are handled, and so on. This article will ...

Instruction Set Architecture (ISA) is a set of instructions defined for the processor’s architecture. These are the instructions that the processor understands. It defines the hardware and software ...
