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 ...

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 ...

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 ...

As smartphone users, we carry an incredible amount of computing power in our pockets every day. Even today's most affordable phones boast exponentially more processing power than, for example, the ...

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 ...

Important financial and market forces are creating unprecedented growth and dynamism in the semiconductor industry. The present dynamics include: • A worldwide chip shortage impacting industries large ...

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 ...
