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 ...

CISC chips became more RISC-like, while RISC chips ramped up complexity, capabilities, and die size. A good example of this trend is the entire ARM vs. x86 debate.

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 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 ...

Die Prozessor-Hardware eines derartigen RISC-Prozessors ist aber so einfach strukturiert (reduziert), daß sie auf einem Bruchteil der Chipfläche des CISC-Prozessors realisiert werden kann. Dies legt ...

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 ...

Zwei Argumente werden bei der Diskussion der Vorteile von RISC-Architekturen immer wieder ins Feld geführt: hohe Rechenleistung und einfacher Entwurf. Das Aufkommen hochleistungsfähiger ...
