Reviews for the Lenovo ThinkPad S531
Think Slim! Business notebooks are usually conservative and rather bulky working devices. Lenovo’s ThinkPad S531 is one alternative that wants to eliminate this prejudice. It combines typical business features with a slim ultrabook design. We checked if the attractive specifications are convincing.

AMD Radeon HD 8670M: Lower mid-range graphics card based on the GCN architecture.
Modern games should be playable with these graphics cards at low settings and resolutions. Casual gamers may be happy with these 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.
3537U: Fast Ivy-Bridge-based ULV-CPU in Q1 2013. Offers a core clock of 2.0 - 3.1 GHz and an HD 4000 GPU (350 - 1200 MHz). The TDP is rated at 17 W.» Further information can be found in our Comparison of Mobile Processsors.
