Chip Companies Lead Nanotechnology Boom

Small Scale, Big Business In the wake of the dot-bomb crash, tech investors are turning to nanotechnology as the next big thing, with huge advances in materials science, manufacturing, and medical treatments on the horizon. But while the headlines predict a sci-fi future of microscopic robots clearing clogged arteries or Read more…

Shedding Light on Optical Processors

Will Tomorrow’s CPUs Give Off Light Instead of Heat? There’s been a lot of talk about the convergence of computing and communications in recent years — a lot more talk than actual convergence. One reason or stumbling block has been that modern communications systems are increasingly optical, with beams of Read more…

PDA Processors, Part 1: ARM Wrestling

Power to the Pocket With PC sales flatter than an interstate in Iowa, chip vendors are turning to handhelds for a hand up. Intel Corp. has supplemented its Pentium, Celeron, Xeon, and Itanium with a processor product line for PDAs and smart phones, dubbed XScale, to carry its dominance into Read more…

Mobile CPUs Close Gap on Desktops

Balancing Performance and Power Consumption Once 98-pound weaklings compared to their desktop siblings, mobile processors — CPUs designed for notebook PCs, where power, cooling, and physical space are all at a premium — have steadily narrowed the performance gap over time. And while mobile chips command higher prices (just as Read more…

The Dual-Channel Revolution

Double-Barreled Memory Controllers Boost PC Performance Speedy CPUs grab most of the headlines, but as processors get faster, they put more pressure on other, less prominent parts of PC architecture to keep pace. That’s why perhaps this year’s biggest desktop technology trend is the move to higher-bandwidth memory architectures — Read more…

An AMD64 Platform Primer

Sorting Out the Opteron, Athlon 64, and Athlon 64 FX In October 1999, AMD announced a bold alternative to the proprietary EPIC or Itanium 64-bit processor architecture chosen by Intel: The CPU underdog promised to extend the industry-standard x86 architecture to 64 bits, keeping native compatibility with existing 32-bit software Read more…

AGP 8X: Should You Care?

The Latest Thing, or the Last Hurrah? Latest and greatest PC technologies are often touted as some kind of Second Coming, but the latest example is a third coming — AGP 3.0, the standard behind the new AGP 8X graphics cards. This new version of the Intel-created, royalty-free-licensed specification improves Read more…

If Rivers Were Horses: Deciphering CPU Codenames

You Can’t Tell the AMD and Intel Players Without a Scorecard Let’s face it, keeping track of CPU trademarks is hard enough — you’re a serious geek if you can tell the difference between Xeon and Itanium. (The first is what Intel calls its 32-bit server CPUs, relatives of the Read more…
