Thank You We'll get back to you soon! We found virtually nothing to criticize. All materials, transitions, and edges were virtually flawless and we considered the XPS 15 to be on par with the current generation of Apple MacBooks. In terms of the case, it is entirely a matter of personal taste when determining the superior case between these two inch notebooks. However, the inclusion of USB 3. Additionally, the XPS 15 includes a modern mini-DisplayPort connection that can offer high-resolution output to and inch monitors.

The older, analog VGA port was removed in this revision cycle. Apart from the above, the XPS 15 only offers standard connections — Gigabit LAN, Kensington lock slot, headphone and microphone jacks, and a 3-in-1 card reader.

All of these interfaces can be found in cheaper notebooks as well. The corresponding peripherals are still prohibitively expensive. The port layout has been designed for right-handed users as most of the connectors are located on the left side. This leaves the work area for right-handed users effectively clear of cables. In our opinion, positioning ports on the back would have been even better.

However, we can praise the large spacing between individual USB ports. Even bulky USB memory sticks did not block adjacent ports and the only problem we might foresee requiring an extension cable is a large DVB-T receiver.

The claims of high-end for notebooks are never simply limited to fast CPUs and graphics card but also apply to the small details such as Wi-Fi adapter. Thanks to its 2x2 multi-stream technology and support for The built-in 1.

Naturally, the small camera sensor became very blurry in low light scenarios but does not perform worse than most competitors. We liked the clear and articular sound much more. The XPS 15 comes in a stylish cardboard box which unfortunately contains few accessories. Beside the notebook, built-in battery, and power supply, we only received a driver CD and a few brochures.

The pre-installed software package offered a little more. There is also the typical trial version of McAfee Security Center and an extensive collection of Dell tools and utilities. Tech-savvy users can conceivably replace every component of the XPS 15 without fear of voiding the warranty.

However, amateurs are advised not to open the device. Doing so requires the proper tools, including a T5 screwdriver. Dell is worthy of praise for providing such detailed maintenance instructions. Dell typically provides a 1-year warranty with options for extensions at various premiums. Our sample XPS 15 uses a fairly compact chiclet keyboard without a dedicated numeric keypad.

A three-way adjustable backlight maximum, medium, and off automatically activates when one types, allowing a user to write in the dark. This further enhances the already-elegant overall impression of the keyboard.

We also detected no rattling or flexing even during vigorous tapping. As is typical for many notebooks, keystroke seemed a bit short but we became accustomed to this after a short period of time. Gamers may complain about the somewhat small arrow keys which use the same form factor as other competitors, including the MacBook Pro Compared to the XPS 13, Dell chose a slightly larger touchpad for the inch version. This touchpad has dimensions of With dry hands, the surface is also exceptional with its low friction.

Both the entire touchpad and individual functions and multi-touch gestures can be disabled using a pre-installed driver panel. Not everyone will be happy with the built-in mouse buttons. This design requires an acclimation period for users who are not familiar with it. In terms of workmanship, virtually no negative comments can be said about the touchpad.

Haptics and the crisp click sound both appeared to be of the highest quality. When we tested the first Dell XPS 15 in , we were impressed by its excellent display. Core technical data has not changed since then. This XPS 15 still uses the This pixel density falls between the standard density display and the Apple MacBook Pro 15 with Retina display which has an enormous dpi.

We used quotation marks around the only as this brightness is still extremely bright and can only be achieved by a handful of notebooks. On battery power, the brightness was reduced by approximately 10 percent. We would subjectively describe the brightness distribution of the display as being very even, an impression we confirmed in testing with a good illumination level of 90 percent. This yields an excellent contrast ratio which represents the current upper-class of notebook displays.

As a result, the extremely large color space of previous models is now significantly less. The display of the current model only matched entry models in this regard and neither the AdobeRGB or sRGB spaces were completely covered. This restricts the notebook from being used in professional image editing. However, this is a limitation that is largely irrelevant for most users and thus should not be overstated. While the glossy Gorilla Glass surface provided a subjectively higher contrast and vibrant colors indoors, it became an unpleasant obstacle outdoors.

We could not completely avoid annoying reflections and, despite the strong backlight, screen readability deteriorated significantly, especially in direct sunlight. On the other hand, the XPS can be easily used in the shade, even with the slightly reduced backlight on battery power.

Although viewing angle stability is not one of the strengths of TN technology, this particular display achieved good results in this category. When viewed from the side, the display contents remained mostly unchanged over a wide arc provided the user does not deviate too much in the vertical axis. For better performance, the manufacturer would have to use an IPS or VA panel which would further increase the total price.

Business customers can choose the Core iM or iM. All four processors have a lower Watt TDP , a strength considering the new, slimmer case. Our test model included the fast Core iQM processor which utilizes four cores operating at a clock speed of 2. The maximum speeds for various core operations are 2. The processor also supports Hyper-Threading technology which enables the parallel processing of up to eight threads in this quad-core processor.

More details regarding the features of the Core iQM can be found here and extensive benchmark results can be found in our online database. Like in its predecessor, dynamic graphics switching in the new XPS 15 is performed by Nvidia Optimus. When idle, the notebook uses the processor-integrated Intel HD Graphics for video playback and other less-demanding tasks. While the HD Graphics is not particularly fast or powerful, it is extremely energy efficient.

Although the Intel Core iQM has a clock speed that is a few hundred MHz lower than the Watt Ivy Bridge quad-core processors, it nonetheless provides impressive performance on a high-end level.

In both single- and multi-threaded benchmarks, we were able to observe the corresponding maximum Turbo Boost speeds which led to correspondingly good results. Our test candidate reached 5. Full performance was available even on battery power. Anyone choosing the basic dual-core Core i should expect a performance decrease of approximately 50 percent while single-core performance should be nearly identical. The primary advantage is the reduced power consumption of the Core iQM.

Storage devices often present a difficult decision. Even after recent price reductions, fast SSDs are still at least ten times more expensive than conventional physical hard disks in the 2. One solution to this problem is to use a physical hard drive for storage and add a smaller SSD as a flash memory cache for frequently used programs.

For the XPS 15, Dell has chosen this option. In Windows, the user only sees a shared disk with GB of storage space. The SSD cache drive is inaccessible to the user and is automatically managed independently of additional software. Because of this hybridization, it is difficult to isolate the performance of the individual components of the storage solution.

On the other hand, boot times were not subjectively faster. Despite these optimal features, the XPS 15 scored unexpectedly poor results in our benchmark tests. The graphics-oriented 3DMark was not affected by this situation and the XPS delivered an excellent score of points. In the more processor-intensive 3DMark05 and 3DMark06 , the score was considerably reduced.

We observed a problematic and drastic CPU throttling that occurred even in the latest 3D games. Depending on the game being tested, the reduced processor clock often reduced frame rates and playability.

In Anno for example, there was virtually no discernible difference in performance when compared to other notebooks with the same graphics card. Even at only 1. The game was smooth using high details at a resolution of x In Alan Wake and Battlefield 3 , the negative impact of throttling was minimal as well but performance was only sufficient for medium details. In Diablo 3 and F1 , we found a different situation. Both games showed high CPU limits, especially at low resolutions. Nonetheless, this behavior represents a significant limitation and resulted in unplayable frame rates during more demanding scenes.

Further details on the possible causes of this limitation are described below in the Temperature section. While the fan was typically inactive when the notebook was idle or carrying out simple tasks such as word processing, the XPS 15 was not completely silent.

This was due to the hard disk whose faint noise of During more demanding tasks, the fan occasionally activated and reached a still-quiet and non-disturbing noise level of System noise became significantly more noticeable at full load. Regardless of whether we were playing a game or running our Prime95 and Furmark stress test, the noise level peaked at approximately 45 dB A. Subjectively, the XPS 15 did not seem particularly loud due to its constant and very low-frequency noise. Even over an extended period of time, we found this volume to be acceptable.

While the ambient temperatures of 24 to 27 degrees Celsius 75 to 81 degrees Fahrenheit are perhaps less than ideal for a test, this is hardly a rare scenario for any mobile device. Under load, the case reached temperatures of over 40 and 45 degrees Celsius and degrees Fahrenheit on the top and underside respectively. Even the soft-touch surfaces which were specially designed to help keep the surface cool did not noticeably help and certainly no one would want to touch the case near the heat exhaust vent in this scenario.

Lap-top use would only be advisable during low-demand tasks. We would like to take the opportunity to discuss the aforementioned throttling. In our testing, it seemed that the cooling system was simply unable to dissipate the generated heat quickly enough. After several hours of Battlefield 3 , we observed processor temperatures between 95 and 97 degrees Celsius and degrees Fahrenheit even though the CPU was constantly operating at a reduced speed of 1.

Our stress test was able to reproducibly shut down the XPS 15 after five to fifteen minutes as the processor exceeded degrees Celsius degrees Fahrenheit. The graphics card also became very hot with a temperature of 91 degrees Celsius degrees Fahrenheit but managed to maintain its maximum clock speed. At this point, it is difficult to say whether the cooling system was simply inadequately designed or if there might be other issues, such as a problem with the applied thermal paste and transfer pads.

Both a pre-production model and a retail model demonstrated the same behavior so we are willing to rule out the possibility of a single defective unit. We are already in contact with Dell and will update the review when a solution emerges. While this revision eliminated both the stress test shutdown and CPU throttling, it also created new problems. We would advise gamers to wait for further updates. We will continue to update this article regarding this issue as solutions emerge.

As part of the case redesign, Dell chose to use different speakers for the XPS The previously-used Watt 2. What initially appears to be a massive downgrade still manages a quality that would surpass 95 percent of all other notebooks in practical use.

We observed clear high-tones , strong mid-tones, and considerable depth. This allows the user to enjoy music and movies without the need for external speakers. The generous volume level was sufficient to fill medium-sized rooms without distortion or overdriving at maximum volume.
