Five Things You Didn't Know About Dual-Core Processors

Dual core processors have been the subject of so much hype that perceptions about the technology seem to have trumped some of the realities.

Both AMD and Intel have posted Web pages in which they extol the virtues of their respective dual-core devices. That makes timely sense, since most industry watchers agree that 2006 is the year dual-core will become ascendant.

However, hidden in the such venues, and among numerous news stories on the subject, are some surprising and uncommon facts. Accordingly, we bring you five things you probably didn't know about dual core.

Intel and AMD weren't the first to ship dual-core processors.

The widespread assumption is that the dual-core duel has been fought solely on the PC front, with AMD and Intel vying for the title of first to market. That's incorrect.
In fact, IBM beat both companies to the multicore punch, albeit with a non-X86, server processor. That occurred when Big Blue rolled out its dual-core Power 4 chip in 2001, for use in IBM's RISC servers, in 2001.
