Resellers are beginning to show a Hewlett-Packard Pavilion laptop with Intel's more powerful mobile Core i5 processor, which will debut at the Consumer Electronics show on Thursday along with its lower-end sibling, the Core i3.
The 15.6-inch HP Pavilion dv6-2170us comes with a 2.26GHz Intel Core i5-430M processor that is advertised as automatically overclocking to 2.53GHz via Intel's Turbo boost technology. This feat is not possible with laptops packing the Core i3 chip, which doesn't feature Turbo Boost.
Intel will officially roll out the mobile Core i5 and i3 processors on Thursday in tandem with a slew of system announcements from PC makers. The Core i5 and i3 are the first Intel laptop processors to combine two processor cores and a graphics function in one chip package (previously, the graphics chip was in a separate chipset), resulting in better overall power efficiency.
The Core i3 and i5 part ways on Turbo Boost technology, which speeds up or slows down individual cores to meet processing or power efficiency needs. This will only be offered in higher-end Core i5 and i7 processors.
Both the i3 and i5 come with Hyper-Threading, which can double the number of tasks--or threads--a processor can execute. This is not offered in current Core 2 chips.
