The HP Spectre XT TouchSmart Ultrabook 15t-4000, besides having a long name, has a sleek design, a comfortable keyboard and a Thunderbolt peripheral port. It also has speedy performance thanks to its Intel Core i7 CPU and 8GB of RAM, but battery life is lacking.

Overall, HP did a great job with the Spectre XT TouchSmart, releasing a notebook with a sleek, comfortable design and a top-notch touch display. While we want to give this Ultrabook high marks, we can't overlook that the poor battery life and high price could be dealbreakers for some. If you can live with those compromises and your pockets are deep enough, by all means splurge.

The $1,349 HP Spectre XT TouchSmart Ultrabook 15t-4000 is a good-looking machine with solid performance, a beautiful 1080p touch- screen display and fairly loud and clean Beats Audio. However, for this price, we would like to see either a full solid state drive or integrated graphics. Although it has a lower-res screen, you can pick up the touch-enabled Dell Inspiron 15z with a similar processor and discrete Nvidia GPU for $250 less than the HP.

Intel HD Graphics 4000: Processor graphics card in the high end Ivy Bridge models. Offers a different clock speed in the different CPU models (ULV to desktop quad core) and therefore a different performance.
Non demanding games should be playable with these graphics cards.
» Further information can be found in our Comparison of Mobile Graphics Cards and the corresponding Benchmark List.
Intel Core i7: The Intel Core i7 for laptops is based on the LG1156 Core i5/i7 CPU for desktops. The base clock speed of the CPUs is relatively low, but because of a huge Turbo mode, the cores can dynamically overclock to up to 3.2 GHz (920XM). Therefore, the CPU can be as fast as high clocked dual-core CPUs (using single threaded applications) but still offer the advantage of 4 cores. Because of the large TDP of 45 W / 55 W, the CPU is only intended for large laptops.
3517U: Fast Ivy-Bridge-based ULV-CPU in Q2 2012. Offers a core clock of 1.9 - 3.0 GHz and an HD 4000 GPU (350 - 1150 MHz). The TDP is rated at 17 W.» Further information can be found in our Comparison of Mobile Processsors.
