ARMing THE WORLD
No one would have believed in the last years of the 20th century that the processor world was being watched keenly and closely by intelligences greater than Intel’s. Yet in the UK, intellects vast and cool regarded the processor market with envious eyes, slowly and surely drawing their plans against Intel…
Apple is dumping Intel processors for its own design of silicon. How did this happen, and what, if any, are the ramifications to the wider PC market? How can a processor design that started life in an obscure, failed British home computer of the 1980s now challenge the entire Intel empire? We’re going to delve into the ARM microarchitecture, have a look at how it’s advanced over the years, how those architectural advances have borne out in benchmarks, and contrast the results to those of Intel desktop parts.
As we do this we’re going to find two contrasting stories: One of maximising performance increases generation by generation, and the other offering fixed incremental increases from generation to generation. We can delve behind the reasoning for why those increases played out like they did, and we can argue if ultimately those have been good decisions or not.
We can also argue about competition in the marketplace and ultimately how that’s good for us, the consumer. But an architecture running an entirely different instruction set – is that good for PC consumers? Perhaps we’re getting ahead of ourselves. NEIL MOHR What is an Intel processor? What is a PC?
