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 ...

The Mac's best quality: software A Pioneer Press piece opines that the best part of the Macintosh platform is elegant, well-designed software. "So what does Macintosh have going for it? The most ...

The push for open source isn’t limited just to software; in fact, there’s quite a big push for open-source hardware as well. Founded in 2015, the RISC-V (pronounced “risk five”) Foundation, now RISC-V ...

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 ...

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 ...

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 ...

SAN JOSE–Looking to alter the embedded chip landscape, startup MemoryLogix Inc. took the Microprocessor Forum last week to unveil the company and disclose the development of a “586-based ...

Ok I've been reading about computer development in the late 80's to early 90's. Such as the hype around RISC CPUs. RISC at the time was suppose to drive i386 out of the market. Microsoft even put ...

RISC-V, pronounced “risk five,” is a modern open-source instruction set architecture (ISA) based on reduced instruction set computer (RISC) principles. In simple terms, it’s like a blueprint that ...
