Dell Inspiron 15-5548 Notebook Review

Sascha Mölck, Tanja Hinum (translated by Liala Stieglitz), 05/08/2015

All-rounder. With its stylish design, Dell's 15.6-inch Inspiron 15-5548 all-rounder aims to attract the attention of potential buyers. The hardware equipment is satisfactory. However, Dell should have put more effort in terms of GPU and screen.

For the original German review, see here.

Dell's Inspiron 15-5548 belongs to the 15.6-inch all-rounder category. It has enough computing power for everyday life and thanks to the combination of a Core i7 Broadwell processor and Radeon R7 M270 graphics core, can render computer games. The present Inspiron is the Broadwell upgrade of Dell's Inspiron 15-5547. Our report reveals whether the new processor provides any advantages.

Laptops like Acer's Aspire E5-571GToshiba's Satellite S50-B and HP's Envy 15 belong to the competitors. The Aspire VN7-571G can also be included in this faction, although, it is  aimed more at the gamers' group.

Since both Inspiron models we have tested feature an identical build, we will not go into details about casing, connectivity, input devices or speakers. The corresponding information can be found in the review of the Inspiron 15-5547.

Display

The Inspiron features a 15.6-inch glossy screen with a native resolution of 1366x768 pixels. Unfortunately, the screen has a very low brightness of 199.8 cd/m². Such a low rate is unacceptable for a 700 Euros (~$785) laptop. The screen in the rival Acer's Aspire E5-571G (226.2 cd/m²) offers a marginally higher brightness. Strangely, the screen has a slightly higher brightness in battery mode than in the AC mode.

Both the contrast (439:1) and black level (0.49 cd/m²) are acceptable, but not  exceptional. It looks worse for the Aspire (290:1; 0.77 cd/m²). The Inspiron's screen cannot reproduce either the AdobeRGB or the sRGB color spaces. The coverage rates are 39% (AdobeRGB) and 61% (sRGB).

The screen exhibits a DeltaE 2000 shift of 8.82 in the state of delivery. A rate less than 3 would be desirable. Beyond that, the screen also has a bluish cast.

Dell has equipped its Inspiron with a viewing angle dependent TN screen. Therefore, the screen is not legible from all positions. The viewing angle is quite generous horizontally, and even several viewers can look at the screen simultaneously. Changing the vertical viewing angle quickly leads to image distortions. The Inspiron can hardly be used in the outdoors; the glossy surface makes it  difficult to impossible.

System Performance

The system ran smoothly and we did not experience any problems. The PCMark benchmark scores are very good. We are not surprised that it outclassed laptops based on the same CPU but a considerably stronger graphics core, such as HP's Envy 15-k203ng. The Envy performed the benchmarks with a higher resolution (Full HD vs. HD). The Inspiron's lower resolution is one of the reasons for its better results. Beyond that, the PCMark 8 benchmark in particular benefits from AMD graphic cores, which we have frequently observed. The performance of Dell's laptop can be increased by replacing the hybrid hard drive with a solid-state drive.

Graphics Card

A graphics switching solution (Enduro) has been integrated in the Inspiron, which is comprised of Intel's HD Graphics 5500 core and AMD's Radeon R7 M270 GPU. Intel's core is used for routine and battery mode. The Radeon core is enabled when a lot of graphic power is needed, for example in computer games. Switching between cores is done automatically as a rule, but it does not function quite as smoothly as with Nvidia's counterpart (Optimus). Therefore, the user sometimes has to intervene manually.

The Haswell precursor/sister model of the Inspiron - the Inspiron 15-5547 - is equipped with a Radeon R7 M265. Anyone expecting slightly more power from the R7 M270 GPU due to its higher number will be disappointed. Both GPUs are technically identical, support DirectX 11.2 and clock at up to 825 MHz. accordingly; the 3DMark benchmark results are on par. In addition, the GPU was renamed "Radeon R7 M265" in the Device Manger after installing the latest AMD graphic driver.

Gaming Performance

The Inspiron can render games smoothly in the screen's native resolution using medium to sometimes high quality settings. This is mostly true for games that do not have extremely high hardware requirements. Current smash hits like “Evolve” require reducing both the resolution and quality level. For a considerably higher gaming performance, other laptops have to be considered, for example, Acer's Aspire E5-571G is equipped with a GeForce 840M and is available for a starting price of 600 Euros (~$673). If that is not enough, models from Acer's Aspire VN7-571G series would come into the equation. Models with GeForce GTX 850M or GeForce GTX 950M graphics cores are available for prices ranging from 750 to 800 Euros (~$842 to $900).

Emissions

System Noise

The fan runs permanently at a low speed while idling, and is barely audible. However, it speeds up noticeably under load. We measured a consistent noise level of 46 dB(A) during the stress test - not a good rate. Rivals like Acer's Aspire E5-571G are much quieter under load.

Temperature

The Inspiron in the stress test
The Inspiron in the stress test

The Inspiron performed the stress test (Prime95 and FurMark run for at least one hour) differently in AC and battery mode. The processor clocked at 1.9 to 2 GHz and the graphics core ran at full speed (825 MHz) in AC mode. The GPU ran stably at 400 MHz and the CPU clocked at 2.1 to 2.2 GHz when performing the stress test in battery mode. The laptop does not heat up excessively. During the stress test, we measured temperatures of over 40 degrees Celsius (~104 °F) in the area of the fan. This looks the same in rivals like Acer's Aspire E5-571G.

Energy Management

Power Consumption

The Inspiron's idle power consumption was below 10 watts - a normal rate for 15.6-inch ULV laptops. The power consumption climbed to 44 watts during the stress test. The rate would be higher if the CPU did not throttle. There is still some room for improvements. The power supply has a rated output of 65 watts.

Battery Runtime

The Inspiron manages an idle runtime of 7:56 hours. A rival, such as Acer's Aspire E5-571G (13:15 h), lasts considerably longer. Idle mode is ascertained using a Battery Eater Reader test. The screen is set to minimum, the energy saving plan is enabled, and the wireless modules are off. The Inspiron shuts down after 1:17 hours of load; the Aspire (2:52 h) runs over twice as long. The load runtime is measured with Battery Eater Classic tests using maximum screen brightness, the high performance profile, and enabled Wi-Fi modules.

Dell's laptop stopped our Wi-Fi test after 5:48 hours. Again, the Aspire (6:52 h) defeats the Inspiron. Websites are opened automatically every 40 seconds using a screen brightness of approx. 150 cd/m². We test the video playback time by running the short movie Big Buck Bunny (H.264 encoding, 1920x1080 pixels) in a loop. The wireless modules are disabled and the screen's brightness is set to approx. 150 cd/m². The Inspiron manages a runtime of 5:30 hours, and is again surpassed by the Aspire (7:04 h).

Overall, the Inspiron's battery life is satisfactory and on par with those of its Haswell precursor/sister model. It is not surprising that the Inspiron is depleted sooner than the Aspire because the latter has a higher battery capacity (Dell: 42 Wh; Acer: 56 Wh).

The battery has a capacity of 43 Wh. It can be removed.

Verdict

Dell Inspiron 15-5548. Test model courtesy of Dell Germany.
Dell Inspiron 15-5548. Test model courtesy of Dell Germany.

Dell has a 15.6-inch all-round laptop in its lineup with the Inspiron 15-5548. It is the Broadwell upgrade of the Inspiron 15-5547. The installed processor has enough computing power for all common application scenarios. The Radeon graphics core allows playing computer games. At least, the laptop runs quietly in idle mode and heats up moderately. With the 1 TB hard drive, owners of the Inspiron will not be lacking storage capacity. The input devices will not overwhelm anyone but are good enough to get by. The screen's brightness could be higher, the contrast is acceptable, but unfortunately, Dell has installed a viewing angle depended TN screen. We would have expected considerably more from a 700 Euro (~$785) laptop. Dell deserves praise for the large maintenance cover that allows accessing the hardware quickly.

In a nutshell, the Inspiron can be called an unspectacular, almost mundane laptop. It cannot really come up trumps in any aspects and outperform its rivals.

Anyone who takes a liking to the Inspiron but are not necessarily dependent on 4 GB of graphics memory and/or a Core i7 processor should take the basic configuration of the Inspiron for 100 Euros (~$112) less. If more graphics power is needed, then Acer's Aspire E5-571G would be an alternative. It also features a Full HD screen and a better battery life.
