It is surprising that such a configuration is much cheaper than our test model. This CPU has a big advantage in multi-core scenarios in particular. Dell therefore also offers configurations with the Core i5-6440HQ quad-core processor. Users with very CPU-demanding applications might want more performance than the ULVs from Intel can offer. The Skylake model manages about 15% better scores in our benchmarks, which is a result of the improved Skylake architecture as well as the slightly higher clocks. This is the Broadwell predecessor of the CPU in our test model, so this is a good chance to compare the two. The latter was equipped with the Core i5-5300U processor. We reviewed the predecessor of the Latitude 15 E5570 – the Latitude 15 E5550 – back in 2015. The CPU runs with a nominal clock of 2.4 GHz, which can be raised to 2.9 (both cores) and 3 GHz (one core) via Turbo Boost, which is utilized on mains as well as battery power. It is a frugal ULV model with a TDP of 15 Watts. Intel's Core i5-6300U (Skylake) dual-core processor is a mainstream CPU and should provide sufficient performance for the majority of users. The latter works well and allows precise cursor movements. Above the touchpad are three additional mouse buttons, which are primarily designed for the TrackPoint. Under the pad are two smooth mouse buttons with a short travel. The slightly roughened pad does not affect the gliding capabilities. They can be activated and deactivated individually in the settings of the pad. The touchpad of the Latitude supports multi-touch and has a surface area of around 10 x 5.4 cm, so there is sufficient space for gestures. All in all, Dell implements a convenient keyboard, which should also be sufficient for frequent writers. There is just minor bouncing during typing. The same applies for the resistance of the keys. The keys are slightly roughened and concave, have medium travel and they have a convenient pressure point. The illumination is controlled via function key and there are two illumination levels. Dell once again uses an illuminated chiclet keyboard with a numeric keypad. There are no differences between the review unit and its predecessor in terms of input device.
