Both the ENVY 15t and ENVY 17t pack the new Core i7-4710HQ quad-core processor, delivering top-notch performance that will be up to just about any task you put it to. They also share a standard 1TB hard drive, giving you plenty of space to store all your media and files. Despite the 17t being bigger, you'll find the same array of ports on both laptops, which includes three USB 3.0 ports, HDMI, ethernet, a DVD-RW, and a multi-card reader. Even before we get to any differences, both of these laptops have a lot to offer.
