![]() In this way, the notebook achieves a value of about 526 points from the second run on. If you run only the multi-core test, they barely average out at 2.4 GHz. Away from the outlet, these values are decent. In battery mode, the clock speed is 3.4 to 3.5 GHz on average. Such a sudden temperature change is not very likely, so we must question the information of the sensors on the core temperature. By just starting Cinebench, the core temperature jumps from 50 - 70 ☌ (~122 - ~158 ☏) up to 98 ☌ (~208 ☏) for a brief time, before they lower again to 71 ☌ (~160 ☏). The values that the sensors report via HWiNFO are also surprising. The outliers downwards trend without an external cause is striking. Perhaps there are some specific background processes that interfere with the performance, but we do not know the real reason. For a short time, the CPU can get up to 44 watts, which means that the first run is not really representative. After the first, strong run, the values decline in the second run and then level off. In our 30-minute Cinebench loop, the typical behavior of the ultra-efficient CPU is showing. #Dell t7570 drivers windows 7 full#The decisive factor is the cooling system and notebook configuration, determining whether the CPU can use its full performance potential or it is throttled because of high temperatures. They have a very variable clock speed of 1.8 to 4 GHz. Thanks to Hyperthreading, its four cores are able to run two threads each. The Intel Core i7-8550U is an energy-efficient processor of the Kaby-Lake-refresh generation. ![]() This was mainly in the top right corner visible in very dark scenes and that only when you were looking for it. As typical for IPS displays, we also noticed some slight screen bleeding. But more on this later.Īt 91%, the brightness distribution turns out very strong, so the brightness is distributed very evenly across the display. The combination of the barely acceptable brightness and reflective surface creates some doubts as to the outdoor suitability of the device. In addition, the display of the new Inspiron is also reflective. However, at a maximum of 275 cd/m 2 the competitors are not much better either. With the exception of the mediocre TN panel of the sibling model, this is the worst value in the comparison. Probably the biggest weakness of the display is the relatively low average brightness of 240 cd/m 2 . While the display used is convincing in many respects, it also has two or three weaknesses. Optionally, you can also get a (much more expensive) version with a 4K UHD display including the touch function. In our test unit, Dell has used a 15-inch Full HD IPS panel made by BOE. However, the workmanship in our test unit leaves a good impression overall. In some places, the gaps turn out slightly larger. The gaps between the top holding the keyboard and the bottom edge are not always completely even. The battery is built-in, and there is no maintenance hatch. The openings for the speakers are at the bottom in the front, and the fan vents are further back. The lid cannot be opened with one hand, due to the relatively light base and the stability of the hinges, which hold the display in position well. ![]() Because of the aluminum, it appears more resistant than some of the plastic competitors. The same goes for the lid, although naturally it is not quite as robust. The bottom with the keyboard base is comfortably sturdy, and there are no creaks when pressing down on it. The design is kept nicely modest, only the reflective "Dell" logo stands out in the center of the top. ![]() Even though it has an AMD GPU, its performance is at about the same level as that of the 940MX.Īccording to the manufacturer, the case is made of aluminum with "glass-bead brilliance." Whether there are glass beads or not, the silver aluminum case provides good stability and a high-quality appearance to the new Inspiron. As the fifth comparison device, we have selected the Inspi5567-1753 also from Dell. We are evaluating the new Inspiron, comparing it against the Asus VivoBook S15 S510UQ, the Acer TravelMate P658-G2, the Lenovo IdeaPad 510-15IKB, and the Huawei MateBook D. While all these models are also equipped with a GTX 940MX, their processors are different, even if they are always Kaby Lake CPUs. ![]() (A similar model starts from $780 in the US.) Today we are testing the device with the long name "Dell Inspi(7570-9726)." This is a business or all-round device with the new Kaby Lake processor and the GTX 940MX by Nvidia. They are differentiated by the long number that follows the designation. All are called "Inspiron 15," which can become confusing to the customer. For the original German review, see here.Īt this point, there are numerous models from the Dell Inspiron 15 series: gaming notebooks with various Nvidia or AMD graphics cards, business models without a dedicated graphics card or with a smaller version, many different designs, etc. ![]()
