Intel launches power-efficient Penryn processors

Intel on Sunday launched its long-awaited new line of power-efficient microprocessors, code-named Penryn, designed to deliver better graphics and application performance as well as virtualization capabilities.

Intel has teamed up with 40 original equipment manufacturers to deliver Penryn-based Xeon and Core 2 processors. Vendors including Hewlett-Packard and Lenovo have already announced business desktops with Penryn-based quad-core Xeon 5400 processors, with more server announcements scheduled to come soon.

The processors, manufactured using a 45-nanometer process, feature smaller transistors and cut down on electricity leaks, which makes them faster and more power efficient than earlier 65-nm processors, said Stephen Smith, director for Intel’s digital enterprise group operations.

The most power-hungry Penryn-based systems will consume no more than 120 watts. Penryn-based notebooks that are due in the first quarter of 2008 will use 25 watts, Smith said. Today’s 65-nm notebooks consume 35 watts of power, Smith said.

While cutting down on power usage, Penryn processors jump to higher clock rates and feature cache and design improvements that improve the processors’ performance compared with earlier 65-nm processors, Smith said.

Intel will ship 12 new quad-core Intel Xeon 5400 server chips in November with clock speeds ranging from 2GHz to 3.20GHz, with a 12M byte cache. In December, it will ship three dual-core Xeon 5200 server chips with clock speeds of up to 3.40GHz and a 6M byte cache.

Intel will deliver the 45-nm Penryn processors in multiple phases, Smith said. In the first quarter of 2008, Intel will release the 45-nm Core 2 Quad processors and Core 2 Duo processors for desktops. In the same quarter, Intel will launch the Core 2 Extreme and Core 2 Duo processors for notebooks. Intel plans to release 45-nm processors for ultramobile PCs in 2008, though Smith couldn’t provide an exact release date.

Pricing of the 45-nm Intel Xeon processors ranges from US$177 to US$1,279 in quantities of 1,000, depending on the model, speeds, features and number ordered. The 45-nm Intel Core 2 Extreme QX9650 quad-core processor is priced at US$999 in quantities of 1,000.
