Microprocessor technology transforms itself with the appearance of Penryn

Lead-free chips based on stamp-sized 45 nanometer (nm) technology containing 820 million transistors that Intel is about to release are the first to use metal gate transistors, speed up operations, limit losses. leakage compared to silicon port engineering.

" If we use transistors that are similar to those of 15-20 years ago, now every microprocessor must be as big as a two-story building, " said Intel's Bill Kircos.

According to Stephen Smith, Intel's director of digital business, the most power-hungry Penryn system consumes no more than 120 watts. Laptops released in the first quarter of 2008 will only consume 25 watts, compared with 35 watts for laptops using today's 65 nm technology chip. In parallel with limiting power consumption, Penryn chips enhance clock clock and cache memory to improve processing speed compared to 65 nm, at least improve 40% - 60% performance. image and video management .

These products will be marketed under 2 Xeon brands (for servers) and Core 2 Extreme (for desktops).

The new 12 quad-core Xeon 5400 chips for servers will be available in the market this November with speeds from 2 GHz to 3.2 GHz, 12 MB cache. In December, three dual-core Xeon 5200 series for servers will continue to be launched, clocked at 3.4 GHz, 6 MB cache. In the first quarter of 2008, Intel will release two products Core 2 Quad and Core 2 Duo for desktop computers. Then there's Core 2 Extreme and Core 2 Duo for laptops. And at an unspecified time next year, Intel plans to release 45 nm chip versions for ultra-small mobile computers.

Xeon chip prices range from US $ 177 to US $ 1,279. Core 2 Extreme QX9650 (for PC gaming) costs 999 USD. All orders are 1,000 orders.

Currently, a number of computer manufacturers such as HP and Lenovo are ready to launch Penryn-based workstations.
