- Processor: The Ultra Low Voltage Intel Core Solo U1500 processor offers a 1.33 GHz speed paired with a fast 533 MHz front-side bus and large 2 MB L2 cache. (An L2, or secondary, cache temporarily stores data; and a larger L2 cache can help speed up your system's performance. The FSB carries data between the CPU and RAM, and a faster front-side bus will deliver better overall performance.) The Core Solo processor delivers enhanced performance for today's demanding applications such as CAD tools, 3-D and 2-D modeling, video editing, digital music, digital photography and gaming. And Intel's Smart Cache technology enables smarter, more efficient cache and bus design for enhanced performance, responsiveness and power savings.
