Retail package

Inside the box we have the usual stuff – along with the laptop itself there’s the AC charger and a few manuals.

dell inspiron 5558 chargerDesign and construction

Overall, Dell Inspiron 5558 (15 5000) has nice, clean looks, it features an all-plastic build, which is pretty standard for a mid-range consumer device. It is similar to last year’s Inspiron 5548 with some slight changes, most notably around the sides, but it still follows Dell’s signature design.

The lid of the device is made out of glossy black plastic (with a white glossy version also available), which is a huge fingerprint magnet, but for people that don’t like glossy plastic, there are configurations of the Inspiron 5558 with gray or silver matte plastic lids. In the center we have the usual Dell logo that is also glossy. On the other side of the lid we have the 15.6” Full HD display, a webcam, and dual microphones. Moving to the bottom of the device, which is also made out of plastic. There you can find an easily detachable service cover, which gives us access to the 2.5” HDD, two RAM slots, WiFi module, and the BIOS/UEFI battery.

Opening the lid reveals rough hard plastic around the keyboard and on the palm rest. The device has a full keyboard (numpad included) and evenly spaced keys, but the Enter button is oddly small. The overall performance of the keyboard is quite decent. The trackpad is made of matte plastic and is large and comfortable. Unfortunately, it does not always properly register the left and especially right clicks which can be somewhat annoying.

Display and Sound

Dell Inspiron 5558 (15 5000) has a Full HD IPS panel, model number 2M4XM-156WF6. The display’s diagonal is 15.6 inches (39.62 cm), with a resolution of 1920 x 1080 (16:9). The pixel density is 141 PPI (pixels per inch), with pixel pitch of 0.18 x 0.18 mm. The screen can be considered “Retina” when viewed from a distance equal to, or greater than 61 cm.

Micr-Dell Inspiron 5558 (15 5000)Dell Inspiron 5558 (15 5000) has comfortable viewing angles. You can see what the screen looks like at 45° angles below.

Dell Inspiron 5558 (15 5000) angles

The maximum brightness before profiling is 207 cd/m2, with a maximum deviation of just 8%. We consider this brightness optimal as it is enough for work in a very bright room (but not enough for using it outdoors). It is also not too high, so you will not have to lower it under typical work conditions. This is good, because the backlight does not flicker only when the brightness is set to maximum (see below). The average color temperature we measured on a white screen with maximum brightness is 6630K – slightly cooler than the optimal 6500K (daylight). There is no unacceptable deviation of the temperature on the surface.

Color Gamut Coverage (CIE)

The yellow triangle indicates the color gamut coverage of Dell Inspiron 5558 (15 5000). The display covers 62% of sRGB and 46% of Adobe RGB color spaces, which is not enough for an image with fully saturated colors.

Gamut-Pre-Dell Inspiron 5558 (15 5000)

The figure below shows the same thing, but it now includes measurements from the screen before calibration. The colored circles show the reference colors (the target) the screen is supposed to show. The white ones are the actual reproduced colors (the hits). The primary and secondary colors are shown with 100% and 50% saturation inside the sRGB color space. The reds and blues are displayed with significant error due to the low coverage (see the white arrow).

Colors-CIE-Pre-Dell Inspiron 5558 (15 5000)

We profiled the display at 140 cd/m2 brightness and color temperature of 6500K.

67Brightness 5558

For calibration purposes we use X-Rite i1Display Pro. We tested the colors before and after saving the profile in Windows. Due to the low sRGB coverage the 100% saturated red and purple colors are replaced with the closest possible, so the calibrator is not able to do much there. Their absence will lead to dull images.

Conclusion

The screen of Dell Inspiron 5558 (15 5000) has sufficient brightness (if you don’t use it outside), high contrast and comfortable viewing angles. After calibration almost all colors from Color Checker are very accurate, which is important for watching videos. Unfortunately, a big part of the sRGB colors are missing, so this makes the notebook unsuitable for work with colors like web-design or image processing.

If we assume a distance of 58cm (~23in) between the human eye and the notebook monitor, then normal (20/20) vision would require a pixel density of at least 150ppi in order to interpret an image as perfectly detailed.

Software

The notebook comes with Ubuntu pre-installed. For testing purposes we performed a clean installation of Windows 8.1. If you need drivers, they can be found on Dell’s official support page: http://www.dell.com/support/home/us/en/04/product-support/product/inspiron-15-5558-laptop/drivers

Battery

Dell Inspiron 5558 (15 5000) offers decent battery life for its price range. It comes equipped with a relatively small 4-cell, 40 Wh battery. The IPS Full HD screen might eat up more of the battery than the usual TN HD screens, but the energy-efficient internals make up for it and overall, we got average results for a mid-range multimedia notebook.

Web browsing

In order to simulate real-life conditions we used our own script for automatic web browsing, which goes through over 70 websites.

battery-browsing-5558

The result we got is about average – 266 minutes (4 hours 26 minutes).

Watching movies

For every test of this sort we use the same video in HD.

battery-movies-5558

The result here is pretty similar – 280 minutes (4 hours 40 minutes).

Gaming

For accurate simulation, we used the Metro Last Light benchmark running on a loop with graphic settings set to minimum.

Here we got a result of 76 minutes (1 hour and 16 minutes).

CPU

Intel_Core_i7_logoIntel Core i7-5500U is a high-end processor released on January 05, 2015. It is part of the “Broadwell” generation and operates at a base frequency of 2.40GHz. If a higher frequency is needed, its two cores can overclock, and if they both operate in tandem, they go to 2.9GHz. The frequency goes up to 3GHz for only one core.

The chip is equipped with 128KB of first level cache, 512KB of second level cache, and 4MB of third level cache. The Core i7-5500U has been developed using a 14nm process, allowing for the integration of the Intel HD Graphics 5500 controller. It operates at a base frequency of 300MHz, while Turbo Boost can increase that to 950MHz. TDP consumption of the whole SoC (System on a Chip) is 15 watts, with a maximum operating temperature of 105C.

Intel Core i7-5500U supports TurboBoost (increasing the clock frequency when necessary), HyperThreading (additional virtual core for every physical one), PCI Express 3.0, DDR3/L/ 1333/1600 memory, AVX, AVX2.0, FMA, QuickSync and the SSE4 instruction set.

Results are from our Photoshop benchmark test (the lower the score, the better)

Results are from the Fritz chess benchmark (the higher the score, the better)

Fritz

Fritz is a chess benchmark which tests the computing capabilities of the CPU with various chess moves. The Intel Core i7-5500U managed to get 5.732 million moves per second. By comparison, one of the most powerful PCs, Deep(er) Blue, was able to squeeze out 200 million moves per second. In 1997 Deep(er) Blue even beat the famous Garry Kasparov with 3.5 to 2.5.

GPU

geforce-920m-3qtrThe NVIDIA GeForce 920M is a low-range GPU that’s included in budget notebooks or multimedia-oriented ones. It was released in March of 2015, and it is based on last year’s GeForce 825M with a GK208 GPU. We expect the GPU to be marginally faster than its predecessor, since Maxwell generation GPUs mostly improve power consumption and don’t emphasize performance as much. However, the TDP is rated at 33W. Furthermore, GeForce 920M offers 4GB of DDR3 memory, 8 ROPs, 16 texture mapping units and 384 shaders. The graphics processor runs at 575MHz with the Boost clock being 954MHz, which should be enough to run most new games at lower settings or use other graphics software that isn’t that demanding. Memory speed is 1800MHz, with a 64 bit bus. Notable features include DirectX 12, NVIDIA Optimus support, OpenGL 4.5 and CUDA cores.

Temperatures

Before we begin with this section we would like to note that the following tests do not represent real-life benchmarking. It is extremely difficult to reach 100% CPU and GPU load under normal usage for such an extended period of time as in our stress tests, but we run them to see how the machine handles higher temperatures and check the overall stability of the system in the long run. First we put the CPU under 100% load for an hour. Under normal usage the CPU maintained a temperature of 44°C, and during our stress test it reached 56 – 59°C, which is a really great result and really far from the maximum operating temperature of 100°C. There was no throttling of the CPU during the entire test. You can see the results on the graph below – the blue is the CPU load and the orange is the temperature.

Inspiron5558-CPU-stress

After the first hour, alongside the CPU we add a GPU stress test and leave them both running for another hour. The temperature of the CPU rose to 80-84°C in a few minutes and remained around that level for the remainder of the test, while the GPU temperature was around 80-82°C during the test. Again, there was no CPU throttling.

Inspiron5558-CPU-GPU-stress

After the stress tests we measure the temperature on the surface of the machine. The Inspiron 5558 remained quite cool on the outside through the entire test and we did not feel any heat. The fans ran a bit loud, but not loud enough to be too disturbing. Overall, the cooling system of Dell Inspiron 5558 passed our stress test with an impressive result.

Verdict

Inspiron_5558Dell Inspiron 5558 is a good mid-range multimedia notebook that offers good specs at a reasonable price. It has enough performance in store to handle even pretty demanding computational tasks, and work with heavy professional software with the Intel Core i7 CPU and 16GB RAM. The discrete (but entry-level) GeForce 920M offers decent performance for some light graphics tasks and gaming on low settings, but you won’t be able to play any heavy games like Thief or Grand Theft Auto V, as it simply does not offer enough performance. You would think that all these powerful components would heat up the machine a lot, but Dell have done a good job with the heat management of the machine. The temperatures, even under heavy load, are far from the operational maximum, and the device was comfortable to touch even after 2 hours of stress testing.

The display of the notebook features an IPS panel, which is great, at first glance. Unfortunately, it does not offer the typical strengths of this type of panel, as it has a pretty low color gamut coverage and it won’t be suitable for work with colors like web design or photo editing. It also has PWM for all brightness levels except 100%, but the maximum brightness is enough for comfortable use in a well-lit room, so you shouldn’t need to lower it under normal working conditions. The keyboard is good for a mid-range device; the keys are evenly spaced and comfortable to type on, and the trackpad is spacy and comfortable. The battery life is decent for the seemingly power-hungry Full HD IPS panel and discrete GPU, but good power management squeezes out about 4 and a half hours of web browsing or movie watching. Overall, this is a very good device with great specs for its price.

Disappointed after 3 years on the nose. Within 6 months it had to be returned under warranty for charging issue. Laptop always seemed “stressed” and ran hot. DVD player stopped working a year ago. This machine was well treated, never dropped. Always a propper shut down. It just rewarded me by not tuning on at all, as if it was fried, but without the smell. I have a brick after 3 years. I have a 15 year old Toshiba with Windows XP that still works. What’s going on with these devit these days? Inferior product from Dell. This has to… Read more »
