With Intel® Rapid Start Technology, your PC can go from being in a very deep-sleep to fully awake in a flash. This responsiveness capability enables your device to consume lower levels of power when you’re not using it, yet resume quickly when you want to use it. You save time and, if you’re using an Ultrabook™, this technology also extends the battery life. If you have an All-in-One, it allows the system to consume less power. Either way, you can start up quickly and get right back to where you left off.
Intel® Rapid Start Technology is available on Ultrabook™, All-in-One, and standard PCs powered by the 3rd generation Intel® Core™ processor family.
Intel® Smart Response Technology gives you the larger storage capacity of a traditional hard drive without sacrificing speed, delivering up to 2x faster performance3,4, and up to 2x faster game launches3,5—all while consuming less power. This feature recognizes and automatically stores your most frequently used applications, games, and files, so you can access then promptly and create, work, and game faster than ever before.
