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 ...

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 ...

Chris has reported for various tech and consumer goods outlets over the past decade, including Android Police since early 2022. Previously, he has contributed to outlets such as NotebookCheck, and ...

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 ...

For any Ars Technica readers who've been with us since 1998 and who fondly recall the "RISC vs. CISC" wars of yesteryear, I've got great news: the battle is back on. Here's a look at the new state of ...

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 ...

In my first blog, we examined gave the historical context of the instruction set battles of ARM and x86, covering the RISC-CISC Wars in the PrePC Era and the PC Era. This blog covers Round 3, the ...

I was just wanting to know if anyone can tell me if the new athlon mp and xp's are risc chips or if they went to cisc. I know the older AMD chips were all RISC, but not sure of the newer ones. When ...

The ARM-based M series is a RISC design rather than Intel's x86 CISC architecture. RISC circuits use less complex instructions, run cooler and thus save battery, which is why an ARM chip is used in ...
