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 ...

Welcome to Upscaled, our explainer show where we dig into the bits of tech that make your gadgets faster. Today, I want to talk about instruction set architectures. Apple announced it's building its ...

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 ...

Simply ask yourself a question. What instruction set do AMD chips excute? If the answer is x86 then these chips are CISC. Any talk about chips being CISC outside and RISC inside is invalid given the ...

RISC-V International, the global open hardware standards organization, has announced that Intel has joined RISC-V at the Premier membership level. Let that sink in for a minute. Intel, which has made ...

The microcontroller sector is evolving in an exciting direction by providing designers with a growing menu of choices tailored to their performance and power requirements. Unlike the classic 1990s ...

Closed systems stagnate innovation—Linux users know this. Licenses, royalties, and fees keep the well-funded in control. RISC-V throws that out the window because it's free to adopt, adapt, and ...

The Android operating system is built to run on three different types of processor architecture: Arm, Intel x86, and MIPS. The former is today’s ubiquitous architecture after Intel abandoned its ...

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 ...

Open-source semiconductor design company SiFive Inc. today unveiled its latest chip design blueprints, the SiFive Intelligence XM Series, saying these are the first based on its RISC-V architecture to ...

Intel is making a few key major foundry moves to bolster its IDM 2.0 strategy, such as setting up a massive $1 billion innovation fund to support both early-stage startups and established companies ...
