Intel P4 Extreme Boosts Performance off the Clock

The move marks a departure from the company's traditional advancement through clock speed, more closely resembling the strategy of rival AMD (NYSE: AMD) .

Intel said the new P4 Extreme was its latest 925XE chipset processor and -- with Hyper-Threading, boosted system bus and better memory -- represented its "platform approach."

The company -- which has recently backed off plans to build processors with higher clock speed -- said that by bringing chipset, processor and other components together, it would deliver improved performance to gamers and multimedia users.

Speed by Other Means

"A new 1066 MHz system bus -- the main path between the [central processing unit] and system memory -- will bring enhanced levels of performance to the latest cutting-edge games and media tools that require extra horsepower," Intel said in a statement, adding the technology will deliver smoother, more realistic 3D gaming and glitch-free video.

The Extreme Edition's architecture and clock speed of 3.46 GHz bear out Intel's announcement last month that it would be looking beyond increased clock speed to drive the performance of its processors.

"Coming after Intel acknowledged that it will not ship a 4 GHz Pentium 4 processor, this processor illustrates the emphasis on means other than clock speed, like the faster frontside bus, to boost performance," IDC program manager Shane Rau told TechNewsWorld.

Rau said the chip industry has recognized the need to de-emphasize processor clock speed in favor of other ways to improve overall PC performance.

"We've been seeing bigger cache and faster frontside buses for years and, more recently, the moves to 64-bit and dual-core processors," Rau said.

Back on the Clock

Gartner (NYSE: IT) research vice president Martin Reynolds told TechNewsWorld that although Intel had little choice but to look beyond clock speed to pick up performance -- mostly because of heat and power issues -- the company and industry will revisit its past again in the future.

"The problem is, if they keep the clock speed and increase the bus speed, they'll run into the law of diminished returns," Reynolds said. "Ultimately, they'll have to return to increased clock speed."

Reynolds said that, in addition to gaming enthusiasts, multi-media editors will benefit from the increased performance afforded by the Pentium 4 Extreme. Those are also the users likely to pay its hefty price, which at $999 per processor in quantities of 1,000 is about double the price of the next P4 down the lineup.

IDC's Rau said the target for the Pentium 4 Extreme is the high end of the desktop PC market, where performance is more important than price.

"Owners of these systems are typically consumers who are willing to pay a premium for the components inside the systems," Rau said. "These consumers typically use their PCs for applications like gaming and digital content creation, which demand greater than average performance."
