Intel Penryn launch takes miniaturisation further

Intel has launched its Penryn processors, which are designed for better graphics, performance and power efficiency.

The company has teamed up with 40 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-nanometre 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, Smith said.

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

The processors deliver a 40 percent to 60 percent improvement in video and imaging performance, Smith said. New instructions on the processor speed up photo manipulation and encoding of high-definition video, Smith said.

Intel's Penryn processor for gaming systems, the 45-nm Intel Core 2 Extreme QX9650 quad-core processor, takes advantage of the instructions and includes a larger cache to deliver better graphics and video performance, Smith said.

Hardware enhancements allow virtual machines to load up to 75 percent faster, Smith said.

The Penryn launch signals a new era in the way Intel manufactures chips, Smith said. The processors are the first to use high-k metal-gate transistors, which make the processors faster and less leaky compared with earlier processors that have silicon gates, Smith said. The processor is lead free, and by the second half of 2008, Intel will produce chips that are halogen free, making them more environmentally friendly, Smith said.
