HP Compaq Adds Penryn To Select Laptops

The firm announced that it will be adding the Penryn chip to four more models today.

Penryn is essentially a shrink of the Core 2 Duo chips, with a few extras like the SSE4 instructions. The previous chips are produced using 65-nanometer manufacturing technology while the new Penryn chips are manufactured using 45-nanometer technology.

Smaller transistors have lots of benefits. Chip makers can improve performance by putting more transistors on the same size chip and dial-down power consumption by getting more work done. There's an economic upside as well, in that the chips themselves can be made smaller. This allows Intel and AMD to cut more chips from a single silicon wafer, reducing the cost to build an individual chip and making investors happy with fatter profit margins.

As of this very moment in time, the 8510p, 8510w, 8710p and 8710w laptops can be configured with the 2.1GHz T8100, 2.4GHz T8300, 2.5GHz T9300 or 2.6GHz T9500, depending on machine.
