At the time that the iAPX 432 (originally the 8800) project was proposed, Gordon Moore was CEO of Intel, and thus ultimately signed off on it. Intended as an indirect successor to the successful 8080 ...

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 ...

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 ...

Intel was, and in some regards still is, the biggest name in the personal computer processor industry, but the company has failed to achieve this same level of success in the mobile market over the ...

If the PC and Intel are joined at the hip, then Intel is hobbled, with 2013’s 10 percent drop in PC sales marking “the worst decline in PC market history,” according to Gartner. ARM seems to have ...

ARM, along with its core licensees, and Intel,along with its x86 CPU competitors, have recentlytaken action to put to rest any remainingdoubt that both camps were on a collisioncourse—ARM touting its ...

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 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 ...

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 ...

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 ...
