Review: Intel launches its Yorkfield desktop processor. Will a bigger cache and SSE4 instruction help it run faster than the current crop of CPUs?

The last time Intel moved an existing CPU line to a new manufacturing process was with the ill-fated Prescott CPU. Prescott was a derivative of the Pentium 4 architecture. Those were in the bad old days, where clock frequency was king and real men ran processors that generated blast furnace heat levels.

Moving to 65nm was supposed to mitigate the Pentium 4s tendency to eat power like a pig in a slop trough. Alas, Prescott proved even hotter than its predecessor.
It wasnt until Intel shipped the Core 2 processor line that the company redeemed itself in the eyes of consumers and performance enthusiasts. And what a redemption: faster performance and lower power, albeit at lower clock rates. The Core 2 CPUs havent officially hit the rarified clock rates of the old Pentium Extreme Edition 965, which ran at 3.73GHz and could fry eggs. Core 2 didnt need to run at those clock rates. Even at one gigahertz or less, Core 2 Duo proved faster and more efficient. Read the full story on ExtremeTech: Penryn Arrives: Core 2 Extreme QX9650 Review

Loyd Case came to computing by way of physical chemistry. He began modestly on a DEC PDP-11 by learning the intricacies of the TROFF text formatter while working on his master's thesis. After a brief, painful stint as an analytical chemist, he took over a laboratory network at Lockheed in the early 80's and never looked back. His first 'real' computer was an HP 1000 RTE-6/VM system.

In 1988, he figured out that building his own PC was vastly more interesting than buying off-the-shelf systems ad he ditched his aging Compaq portable. The Sony 3.5-inch floppy drive from his first homebrew rig is still running today. Since then, he's done some programming, been a systems engineer for Hewlett-Packard, worked in technical marketing in the workstation biz, and even dabbled in 3-D modeling and Web design during the Web's early years.

Loyd was also bitten by the writing bug at a very early age, and even has dim memories of reading his creative efforts to his third grade class. Later, he wrote for various user group magazines, culminating in a near-career ending incident at his employer when a humor-impaired senior manager took exception at one of his more flippant efforts. In 1994, Loyd took on the task of writing the first roundup of PC graphics cards for Computer Gaming World -- the first ever written specifically for computer gamers. A year later, Mike Weksler, then tech editor at Computer Gaming World, twisted his arm and forced him to start writing CGW's tech column. The gaming world -- and Loyd -- has never quite recovered despite repeated efforts to find a normal job. Now he's busy with the whole fatherhood thing, working hard to turn his two daughters into avid gamers. When he doesn't have his head buried inside a PC, he dabbles in downhill skiing, military history and home theater.
