Review Dell Inspiron 15R-5521 Notebook

The golden mean. With its Inspiron 15R-5521, Dell shows a rather unusual combination of energy-saving ULV processor and dedicated middle class GPU. The efficient components do not only indicate a moderate energy demand, but also a long battery life. We have tested the top-class model with AMD's brand new Radeon HD 8730M.
Dell Inspiron 15R-5521

For the original German review, see here.

On its German homepage, Dell currently offers five different versions of the Inspiron 15R-5521. The two less expensive versions are equipped with the fast 1.8 GHz Core i3-3217U, whereas the more expensive ones use the more powerful Core i5-3317U which works at a frequency of 2.6 GHz maximum. 

The graphics card shows huge differences as well. People who want to use the notebook for sophisticated 3D programs (games, etc.) should avoid the entry-level version with Intel HD Graphics 4000 and should, if possible, buy the more expensive version of the AMD graphics accelerators straight away. Because, unlike the current Radeon HD 8730M (28nm process), the Radeon HD 7670M is an old 40nm GPU, and the performance gap tends to be quite huge, as our benchmarks verified. 

The effects of the internal memory are limited. Whether four, six or eight GB DDR3-RAM (1,600 MHz): it hardly matters - at least for normal users. Also the hard disk capacity differs depending on the version. The manufacturer integrates either a 540 or a 1,000 GB HDD (5,400 RPM).

Except for the low-cost version, all the notebooks contain a 6-cell battery of 65 Wh. Glossy display (1366x768), operating system (Windows 8, 64-bit) and optical drive (common DVD burner) are identical. The 15-inch notebook varies between 449 and 649 Euros (~$604 and $873)Some details can be adjusted using the in-house configurator.

Case

Wie wir testen - Gehäuse

four coulours are available
four colors are available

For Dell, great emphasis is put on individuality. In order to address a large group of customers, the 15-inch Inspiron 15R-5521 is available in four different colors. Depending on the configuration the lid and keyboard shine in either “pink”, “red”, “silver” or “blue”. An upgrade from the silver base model to a different version costs 39 Euros (~$52).

Independent of that decision are the sides, which are made of plastic, and the silver-gray edge of the lid. The casing bottom however is black. Due to the extensive use of metal (lid + wrist rest) and the high-contrast material transition, the 15-inch notebook cuts a fancy and classic figure. Only the projecting battery cover and the extremely thick display frame at the lower part did not appeal to us. The round casing front reminiscent of the XPS 15 is also a matter of taste.

Even though the processing leaves a lot to be desired here and there (hinges, transition lid/display frame) and dirt might settle down in some gaps, the Inspiron 15R-5521 offers a decent impression of quality. In the price range below 1000 Euros (~$1344) small flaws have to be almost always taken into account. Most all-round notebooks shows a similar result in that category.

Let’s have a look at stability, which can be classified to be reasonable to good. Only the drive area steps out of line. Especially the number pad yields in case of strong pressure. Otherwise, the case is relatively pressure resistant. Since the hinges are very tight, two hands are required to open the lid. Still, the display shakes if the base is knocked.

The good mobility is a positive highlight. A maximum height of barely three centimeters (~1.18 inches) and a weight of 2.36 kg (~5.2 pounds) are surprisingly low for a 15-inch notebook. 

Connectivity

Wie wir testen - Ausstattung

The interface equipment is based on the typical all-round level, which means it is neither poor nor particularly lavish. Let’s start with the right side, which does not only have an optical drive, but also a Kensington Lock and a USB 2.0 port. Most of the interfaces can be found on the left side. Next to three additional USB ports (2 x USB 3.0), the user can find an HDMI and a power port. It is unfortunate that Dell uses a combined audio jack and a Fast Ethernet port instead of a Gigabit LAN port and that there is no analog image output. eSATA, FireWire and ExpressCard are rare in general.

Additional flaw: due to the arrangement which is based on the front, there is a lack of side space when lots of cables are plugged in; unwanted collisions might follow when using a mouse. Only a card reader is included on the front.

Wireless Communication

The Intel Centrino Wireless-N 2230 module supports Bluetooth 4.0 and Wi-Fi 802.11 b/g/n (2.4 GHz, max. 300 Mbit/s). In the test, the range turned out to be average.

Maintenance

As usual for the multimedia sector, the maintenance possibilities are limited to a minimum. Underneath the bottom flap, which is fixed with two cross screws, only the 2.5-inch duct and the two RAM-Banks are accessible. A comfortable cleaning of the fan is unfortunately not possible. However, hard disk and internal memory can be removed and replaced by laymen. 

Software

preinstalled software
preinstalled software

Concerning the software, Dell focuses on drivers and in-house tools. Apart from the Amazon Browser App, the Inspiron 15R-5521 is mostly bloatware free. To console the customer for the missing recovery DVD, the manufacturer installs a "Backup and Recovery” program. Optionally, the operating system can be restored with the Windows 8 function “Restore” (PC-Settings, General). 

Accessories

One should not expect a large accessory pack when buying the Inspiron 15R-5521. Two thin leaflets (Quick Start Guide + safety instructions), a 6-cell battery (330 g/~0.73 pounds) and a compact 90 Watt adapter (340 g/~0.75 pounds) is all there is. Dell could have at least included a driver DVD.  

Warranty

The standard warranty (collection and repair) extends to 12 months. The warranty can be extended at extra charge. A one-year on-the-spot service amounts to 75 Euros (~$101), two years to 115 Euros (~$155) and three years to 150 Euros (~$202). Additionally, Dell sells an accident insurance for 40-80 Euros (~$54-$108). 

Input Devices

Wie wir testen - Eingabegeräte

Keyboard

The input devices provide a good show. Especially the large key size (14.5 x 14.5 millimeters/~0.57 x 0.57 inches) of the Chiclet keyboard, the dedicated number pad and the elaborate layout impressed us. Only the small F-row and the small arrow keys disappointed us; Like many competitors, Dell restricts itself to half the height (8 millimeters/~0.31 inches). The shiny and extremely sensitive keyboard pad is also a point of criticism. Already after a short time dust particles gathered in intermediate spaces.

The pleasant feeling while typing compensates for that flaw. Only the stroke could have been better according to the author. Brightness and volume can be adjusted with the Fn keystroke combination. Additionally, there is a multimedia control and (de-)activation button for the touchpad and the radio module. Unfortunately, lighting is not included.

Touchpad

The successful touchpad is one of the greatest strengths of the Inspiron 15R-5521. Due to the excellent dimensioning (10.0 x 5.7 centimeters/~0.39 x 0.22 inches), large  screen distances can be covered without removing the finger. The orientation is eased due to the touchpad’s lowered position. Furthermore, the user can be glad about the gesture control. With two fingers, documents, images and websites can be randomly turned, zoomed or scrolled. Even though the cursor position changes slightly while scrolling, we would judge the multi-touch support to be reliable.

The precision and the sliding properties also deserve a good grade. Dell relies on a pleasant and smooth surface. On one hand the two mouse buttons sound loud and rickety, on the other hand the well-defined activation system convinces.

Display

Wie wir testen - Display

As expected, Dell integrates a 15.6-inch HD panel. 1366x768 pixels do not allow an extensive multi-window operation, but considering the graphics power, the chosen resolution is reasonable. Less comprehensible is the shiny surface. Depending on the angle, large reflections can occur. Even indoors there are annoying reflections.

Looking at the display figures, the reason for the glossy surface becomes obvious. Apparently, Dell wants to hide the poor panel quality. The N3KMP_156WH3 (LGD03AB) is only middle class. An average brightness of roughly 200 cd/m² is as modest as a contrast of 340:1. Good panels like the LG Philips LP156WF1 (Asus N56VM) achieve a contrast twice or three times as high.

A black level of 0.6 cd/m² is not outstanding either. Dark movies and games show a remarkable gray tinge. Also the poor color display needs to be criticized. The panel does not even cover a rudimentary sRGB space. Next to a high-class display, the image seems to be rather pale.

What is the result of combining poor intensity with a reflecting surface? Exactly: almost no outdoor suitability. Our photos show that the outdoor use is clearly constrained. At worst, one can only guess what is supposed to be on the screen. People who travel a lot should stick to a non-glare panel.

As the picture below shows, the angles are rather disappointing. Elements with a high black content already show a certain change from small angles on. This is clearly visible as the typical horizontal black borders immediately show a different saturation level. Even from an optimal sitting position, the brightness drifts slightly top-down. Ergo: for many viewers, the Inspiron 15R-5521 is not suitable. Though, one should mention that most of the competing products are hardly better.

Processor

Ivy Bridge
Ivy Bridge

In order to keep the power consumption to a minimum, Dell does not use an “ordinary” processor, but rather an energy-saving ULV model. The Core i5-3317U is a dual-core from Intel’s current Ivy Bridge generation which is formed in the 22nm process, which can handle four threads parallel due to the hyperthreading technology.

The automatic overclocking function “Turbo Boost” cannot be missed. When the cooling permits, the clock speed is clearly beyond the basic level. In the case of the i5-3317U, up to 2.6 GHz are possible instead of the 1.7 GHz. 

An absolute highlight is however the low TDP. The standard models can only dream of using only 17 Watts (35 Watts for the two cores) and the three MB L3-Cache resembles the large dual-core versions. But specifications aside: with the Core i5-3317U, Dell undertakes an exciting experiment. ULV processors are normally found in ultrabooks. Will the choice be an intelligent move or a fail?

Turbo Boost

Great: higher load results in a CPU clock speed settling close to the turbo maximum. It does not matter whether one or more cores are stressed: the Core i5-3317U operates mostly at 2.4-2.6 GHz – even under extreme conditions. The clock speed only falls below 2.0 GHz in the idle operation mode, for energy-saving reasons.

Performance CPU

The performance is more than respectable for a ULV model. In the single-core rendering of Cinebench R11.5, the dual-core with 1.00 points is between the ULV colleagues Core i3-3217U (0.75 points @ Lenovo IdeaPad U510) and the fast 2.5-3.1 GHz 35 Watt Core i5-3210M model (1.25 points @ Dell Vostro 3560).

For the multi-core rendering, the gaps are similar: with 2.40 points the dual-core is 40% above the Core i3-3217U (1.71 points) and 15% below the Core i5-3210M (2.83 points). The performance of the Core i5-3317U corresponds to the 2.4 GHz fast Core i3-3110M, which does not have any overclocking (35 Watts TDP).

Graphics Card

graphics switching

The Radeon HD 8730M is based on the AMD's modern GCN architecture (Graphics Core Next) which is produced in the 28nm process. 384 unified shaders point to the middle class as well as the 900 million transistors and a memory interface of 128-bits.

The old Radeon HD 7670M (Terascale 2 architecture) has to make do with 716 million transistors and a 128-bit interface. Also the clock speed distinguishes the Radeon HD 8730M and the core works normally with 650 instead of 600 MHz. Since AMD HD-8000 series has an automatic overclocking, the DirectX 11.1 graphics card achieves even 700 MHz.

Dell utilizes the GPU model with 2048 MB DDR3-VRAM (900 MHz). Due to the integrated audio controller, HDMI surround-sound can be passed through to external devices.

The most interesting aspect though is the dynamic graphics switch, which AMD labels “Enduro”. Depending on the requirements, a program is either assigned to the processor chip or to the dedicated graphics chip. While games are accelerated by the Radeon HD 8730M, modest applications like the web browser or the video player work on Intel’s HD Graphics 4000 (clocks only with 350-1050 MHz for the ULV models).

At least in theory, because amongst other things, Enduro does not really know what to do with certain programs (“Not assigned”). If a game or a 3D-application performance is suspiciously low, the user should check in the driver menu “Switchable Graphics – Application Setting” (right-click on the desktop) whether the profile “Maximum Performance” is activated.

GPU Performance

The GCN architecture can show its strengths in computationally intensive DirectX 11 benchmarks. Take for example the 3DMark 11 (1280x720, Performance Preset). With a GPU score of 1,368 points, the AMD graphics card lines up just 30% above the 40nm model Radeon HD 7670M (1,056 points @ Toshiba Satellite L850-153) and GeForce GT 630M (1,051 points @ Dell XPS 14-L421X). The GeForce GT 640M is not a threat to the Radeon HD 8730M. Nvidia’s Kepler-GPU works around 25% faster (1,731 points @ Acer Aspire M3-581TG).

Concerning the Unigine Heaven 2.1 Benchmark (1280x1024, High, Tessellation normal), the GeForce GT 640M has definitively more competition. With 21.1 to 23.8 fps, the Radeon HD 8730M calculates ”only” 10% more slowly. The AMD accelerator easily overtakes the GeForce GT 630M (16.4 fps@ Dell Vostro 3460). The Radeon HD 7670M trails significantly: 12.7 fps is a reduction of 40%. 

DirectX 10 Benchmarks, like the 3DMark Vantage (see table), show a similar performance structure. Older DirectX 9 programs have a more straightforward gap. Altogether, the performance of the Radeon HD 8730M tends towards the GeForce GT 640M LE.

The notebook has a 1,000 GB, 9.5 mm (~0.37 inches) high Western Digital SATA-II-HDD (Scorpio Blue WD10JPVT-75A1YT0). For a 5400 RPM model the performance is amazingly good.

Where smaller competitors only have a transfer rate of 60-80 MB/sec for HD Tune, the Western Digital levels out at just 90 MB/sec. The CrystalDiskMark judges the HDD slightly quicker: around 110 MB/sec in the sequential reading and writing test are a respectable result. The average seek time of 16.5 ms is rather unspectacular.

If you want to get the most out of the Inspiron 15R-5521, the hard disk should be exchanged with an SSD. With a Solid State Drive one can save some waiting time. Program installations profit from an SSD as well as charge, boot and transfer processes.

The game speed strongly depends on the CPU requirements of the program. DirectX 9 titles that require less graphics performance, like DishonoredCounter-Strike: Global OffensiveDarksiders II, Borderlands 2 or Call of Duty: Modern Warfare 3 allow gambling with high details and double edge smoothing.

For titles like Need for Speed: Most WantedAlan WakeGuild Wars 2 or Far Cry 3, the user has to be content with average graphics options and deactivated anti-aliasing. In exceptional cases, the power is just enough for minimal details. Assassin's Creed III did not work in the test at all. AMD graphics cards in general have problems there.

Taking all the benchmarks together, a rather decent gaming performance results. With the Inspiron 15R-5521, Dell primarily addresses casual gamers. Although the relative weak CPU clock is noticeable, the negative effects are not grave.

Emissions

Wie wir testen - Emissionen

Concerning the noise emission, the 15-inch notebook is not blameworthy. Like most of its competitors, the notebook is rather quiet in idle mode. The user hears primarily a subtle noise of the hard disk which is accompanied by a temporary clatter. Just 32 dB (A) from a distance of 15 centimeters (~6 inches) should not annoy anyone.

Also in the 3D mode the Inspiron 15R-5521 is not excessively loud. On average 37 dB (A) in the first scene of the 3DMark 06 represents an audible, but not annoying, fan noise. The in-house Dell Vostro 3560 reaches 42 dB (A). Our measurements showed 44 dB (A) at maximum – an acceptable value.

Only the optical drive is to be criticized. Where a normal DVD playback works quietly to some extent, this drive blasts away at 44-47 dB (A) while retrieving data. However, traditional DVD installations are becoming rarer as both digital downloads and streaming continue to grow.

Under the item “Temperature”, the all-round notebook also gets a good grade. Let’s start with the components that do not reach a critical temperature even after a long stress phase. 85 °C (185 °F) at maximum for the processor and 72 °C (161.6 °F) for the graphics card are completely uncritical. According to the CPUID Hardware Monitor, the hard disk only warmed up to 30 °C (86 °F)

The casing heats especially on the left side. After an hour of use with the tools FurMark and Prime95, the notebook reached 43 °C (109.4 °F/top) and 49 °C (120.2 °F/bottom). On average, we could measure just acceptable 38 °C (100.4 °F). Under normal operations the Inspiron 15R-5521 remains noticeably cooler. Around 27 °C (80.6 °F) in the idle mode is no reason for complaint

Speakers

Waves MaxxAudio 4
Waves MaxxAudio 4

The manufacturer relies on the 2.0 system which is hidden in the front of the casing bottom. With activated MaxxAudio-4 technology (ensures more power and higher volume), the sound is indeed useful, but one should not expect miracles. For a perfect sound, the speakers have to be more precise and less tinny.

Otherwise, the sound system is above the standard level. Despite missing a subwoofer one can hear a decent bass. The biggest advantage however is the good maximum volume which is enough for smaller and middle-sized rooms. Using the successful “Dell Audio” software, the sound can be adjusted to personal needs. The MaxxAudio technology offers several preset profiles (music, gaming, language, etc.)

Energy Management

Wie wir testen - Akkulaufzeit

Power Consumption

Due to the economical ULV processor and the modern 28nm GPU, the current drain is below the level of a typical all-round notebook. When the HD graphics 4000 deals with the image calculations in the idle mode, 11-16 Watts sufficed for the test version.

34-35 Watts in operating mode is also moderate. The previously mentioned Dell Vostro 3560 needs approximately 15% more current (42-60 Watts) with Core i5-3210M and Radeon HD 7670M. Multimedia notebooks which are equipped with a 35 Watt CPU and a similar GeForce GT 640M LE are rather wasteful under high loads. As an example one can mention the Sony Vaio SV-S1511X9E/B (50-73 Watts) and the Fujitsu LifeBook AH532 (57-84 Watts).

Currently we use the Metrahit Energy, a professional single phase power quality and energy measurement digital multimeter, for our measurements. Find out more about it here. All of our test methods can be found here.

Battery Life

The good battery life of the 15-inch notebook is not only due to the energy-efficient hardware, but also due to the graphics switching. Around seven hours wireless internet (70% intensity) and 4.5 hours DVD playback (100% intensity) are advantages that not all notebooks have. 2.5 hours in the classic test of Battery Eater (high stress at maximum brightness) also deserve a special compliment. Numerous competitors can only last for one hour. The 65-Wh battery is folded into the casing and not pushed – as for many other devices.

Verdict

Wie wir testen - Fazit

Dell Inspiron 15R-5521 (manufacturer image)
Dell Inspiron 15R-5521

If you do not have high requirements on the image quality, the Inspiron 15R-5521 is a good choice. Dell has designed a trendy multimedia notebook which performs “only” fair to good in most categories, but which does not allow striking flaws. 

If there is something to criticize, it is the second-class display. Brightness, black level, colors, contrast, resolution and angles do not knock anybody’s socks off. Also the poor interfaces (no VGA nor Gigabit LAN, only an audio-jack) are a disadvantage.

Otherwise, Dell does a great job. Most of the customers will not only be satisfied with the battery life and the temperature, but also with the input devices and the performance.

Intel’s Core i5-3317U and AMD’s Radeon HD 8730M form a harmonic duo. Despite the small detail deficiencies, the casing also appealed to us. Metallic surfaces are not standard in the price range below 700 Euros (~$941).

In short: for multi-purpose oriented users, the Inspiron 15R-5521 is worth considering.
