Intel demonstrates quad-core CPU design and compressor cooling technology
At IDF Taiwan Intel demonstrated a working quad-core CPU design for notebooks and a unique compressor cooling technology to keep temperature under control. Scheduled for a launch in the second half of 2008, the quad core chip only came from the fab three days ago. The Penryn chip is expected to be a part of Core 2 Extreme series and Montevina platform in the near future. According to DigiTimes, the processor requires a large cooling system, but "it nevertheless ran the recently released game Enemy Territory: Quake Wars throughout the keynote seemingly without a hitch." At a power rating of 45W, the 840 million transistor chip is surely going to hit the battery life of laptops.
The chip giant has also developed a cooling technology based on compressor technology similar to that used in refrigerators and air conditioners. Intel claims three cylindrical compressors (2cm in diameter and 10cm long) can reduce notebook chassis temp by 10 degrees. Though the firm displayed stand alone compressor, it can be directly incorporated into the system.
Intel is also researching on a special material that is permeable to air but acts as a barrier to liquids. Such a material allows cooling air to pass through keyboard instead of vents on the underside or rear. This technique improves cooling as the keyboard offers a larger surface area for air intake and is less likely to become blocked or covered.
