The Core i5-5xxx mobile processors are named Arrandale and based on the 32 nm Westmere shrink of the Nehalem microarchitecture. Arrandale processors have integrated graphics capability but only two processor cores. They were released in January 2010, together with Core i7-6xx and Core i3-3xx processors based on the same chip. The L3 cache in Core i5-5xx processors is reduced to 3 MB, while the Core i5-6xx will use the full cache and the Core i3-3xx will have no support for Turbo Boost. Clarkdale, the desktop version of Arrandale, is sold as Core i5-6xx, along with related Core i3 and Pentium brands. It has Hyper-Threading enabled and the full 4 MB L3 cache.

Interstate 5 (I-5) is the main Interstate Highway on the West Coast of the United States, paralleling the Pacific Ocean from Canada to Mexico and serving some of the largest cities of that part of the U.S., including Seattle, Tacoma, Portland, Sacramento, San Francisco/Oakland, Los Angeles, and San Diego. It links the state capital cities of Washington, Oregon, and California. Its southern terminus is at the United States - Mexico border. Its northern terminus is at the Canada-United States border. Interstate 5 is the only Interstate Highway to touch both the Canadian and Mexican borders. At its southern end, I-5 continues into Tijuana, Mexico, as Mexico Federal Highway 1. On its northern end, I-5 continues into Vancouver, British Columbia, Canada, as British Columbia Highway 99.
