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.

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.
