Face Off: Lenovo Ideapad Y700 15ISK vs. Gigabyte P55W v5 vs. Dell XPS 15 9550

Portable 15-inch gaming. You don't need huge dedicated gaming machines like the G752 or GT72S to play the latest titles. We compare a few smaller notebooks that can be suited for both travel and play outside the home.

Dedicated gaming notebooks are typically designed with expandability and extreme performance in mind. On the other hand, their utility as travel companions for light to moderate office work is almost always on the very low end of the spectrum. What if buyers want the best of both worlds without resorting to smaller 14-inch gaming notebooks that don't provide adequate screen real estate?

The 15-inch category carries a number of gaming and office notebooks that offer a fine balance between work and play. The Ideapad Y700, Gigabyte P55W, and XPS 15 have all been recently refreshed and offer enthusiast-level gaming performance without the gaudy chassis designs that can be a turn off in an office environment.

We encourage users to check out our dedicated review pages below for more data and detailed analyses of each of the three models. This comparison is by no means a replacement, but a condensed aid for those on the fence.

Case

Starting with the Dell, the carbon and aluminum chassis is perhaps the classiest of the three and with excellent rigidity and quality from top to bottom. its resistance to twists and depressions is very good and only with minimal warping under moderate pressures. Instead, our biggest complaints are mostly aesthetic as fingerprints accumulate easily. Our test system also exhibited a bit of a gap at the front edge where it should have been a perfect seal between the materials.

The Gigabyte system is mostly plastic like its previous iterations. Its thinner surfaces are generally more prone to pressure compared to the Dell, especially down the center of the outer lid where the chassis is at its weakest. Attempting to twist the chassis will result in some minor creaking. Meanwhile, the Lenovo lies somewhere in between the Dell and Gigabyte in terms of rigidity. Its base is very resistant to any twists or depressions while its lid is slightly weaker than on the Dell.

The most striking difference between the three notebooks is the size and weight advantages of the Dell over both the Lenovo and Gigabyte. The portability and compactness of Dell's nearly bezel-free design far outweigh any rigidity disadvantages the notebook may have against the Ideapad Y700 or P55W v5. The super small form factor comes at a cost, however, at least in terms of temperature development and hardware features.

Connectivity

Gigabyte's system offers the most connectivity features out of the three notebooks. Not only does it offer the new USB Type-C port, it also includes HDMI and legacy VGA. An optical drive and Gigabit RJ-45 port are also available, both of which are absent on the Dell.

The Lenovo and Dell come in far behind. While the Dell system includes fewer physical ports than the Lenovo, we feel that Dell still comes out ahead due to the more versatile USB Type-C port for better compatibility with adapters.

It's worth noting that certain SKUs of the XPS 15 9550 allow for a secondary 2.5-inch SATA III bay at the cost of a smaller internal battery.

Input Devices

Gigabyte boasts a 2.2 mm travel on its P55W v5 keys compared to 1.5 mm or 1.6 mm on most other notebooks. Indeed, the difference is very tangible and more akin to a desktop keyboard. Feedback is also firm and with minimal clatter for a comfortable typing experience.

The next step down is the Dell keyboard with feedback that is similar to the Gigabyte keyboard, albeit with shallower travel more in line with a standard Ultrabook. The system is lacking a dedicated NumPad and uses half-sized Arrow keys, both of which can be headaches for users who rely on them for day-to-day use. The keystroke on the Lenovo is comparatively softer and lighter and will feel like a bigger jump for users coming from a desktop.

As for the touchpads, all three models offer problem-free navigation and responsiveness. The Gigabyte touchpad is perhaps the smallest since the bottom portion is reserved for mouse clicks only. The integrated mouse keys all have shallow travel with a firm, auditory feedback, but they are more difficult to press on the Lenovo.

Display

With the native resolution held equal between the three notebooks, the Dell system offers the better display on nearly all fronts. Its backlight is much brighter than on the Lenovo and Gigabyte with both higher contrast and wider gamut as well. The Gigabyte is better calibrated out-of-the-box, so XPS 15 users may want to calibrate their screens to improve grayscale and colors at lower saturation levels.

On the other end of the spectrum is the Lenovo display with more inaccurate colors and narrower gamut. Its semi-glossy screen is also a bit more unattractive as the thick overlying touchscreen layer prevents colors and content from popping out.

Response times paint a different picture as the Lenovo panel is generally faster than both the Gigabyte and Dell in Black-White and Gray-Gray changes. This makes an objective winner difficult to choose: Do gamers want to sacrifice the stronger backlight, contrast, and colors of the Dell for a less accurate Lenovo display with less ghosting? It's a hard call where the best answer will depend on user expectations. Fast-paced first-person or third-person titles may benefit from the Lenovo system while LoL or DOTA 2 players will find the Dell more than acceptable and a better fit for office work and outdoor use.

Performance

CPU Performance

Lenovo, Gigabyte, and Dell all offer multiple CPU options beyond what we have here, so this comparison is only between the configurations on hand.

The three notebooks for this comparisons share the same CPU with very similar configurations and, unsurprisingly, their core CineBench and PCMark results are thus very close to one another. Single-core performances out of the Lenovo and Dell are sometimes slower than the Gigabyte according to CineBench possibly due to weaker Turbo Boost on these two systems.

As for troubleshooting and accessibility, the Ideapad is trickier and more difficult to crack open without damaging the chassis.

See our dedicated CPU pages on the Core i7-6700HQ for more benchmarks and comparisons.

GPU Performance

The GTX 970M in our Gigabyte configuration holds an enormous advantage in raw power compared to the GTX 960M. While its clock rate is just slightly slower, it holds twice the CUDA cores and a 50 percent wider bus than the 960M for a 60 to 70 percent performance advantage according to 3DMark benchmarks.

It's worth noting that the Dell system is consistently a hair slower that the Lenovo despite having the same CPU and GPU. The small disadvantage may be attributed to the slower GPU base clock rate of the Dell (1032 MHz) compared to the Lenovo (1097 MHz).

Gaming Performance

The performance gap between the GTX 960M and GTX 970M is very large compared to the gap between the GTX 950M to the GTX 960M or the GTX 970M to the GTX 980M. Depending on the game, users can expect up to 50 percent higher frame rates with the Gigabyte system when the notebooks are stressed.

Stress Test

To test system stability, we run both Prime95 and FurMark to simulate maximum stress. These unrealistic conditions do not represent daily workloads, but are instead meant to put both the CPU and GPU at 100 percent capacity.

The Gigabyte is the only system where its CPU will not throttle slower than its base clock rate even when under extreme stress. Of course, the downside to its impressive performance is the resulting very high core temperature reaching well over 90 C compared to the high 70s or low 80s in the Lenovo and Dell, respectively. Lenovo runs coolest while the extra-thin Dell runs almost as warm as the Gigabyte. It's worth noting that the GPU clock in the Dell runs stably at a higher rate than in the Lenovo.

Gigabyte comes out the winner in this category in terms of performance. The temperature trade-off, however, is a high price to pay.

Emissions

System Noise & Temperature

The loudest and warmest notebook is the Gigabyte, which is unsurprising given our history with other Gigabyte notebooks and the fact that that the P55W v5 carries a more demanding GPU than both the Lenovo and Dell. The single system fan is always audible no matter the workload whereas the Dell is silent under low workloads. The Lenovo is quiet under similar conditions as well, though its fans tend to pulsate from time to time. The Lenovo and Gigabyte level off at the 40 dB(A) range under gaming (Unigine Heaven) loads while the Dell levels off at a quieter 36+ DB(A) range.

Surface temperature development is about the same on average between the Dell and Lenovo. Their hot spots, however, are very different. The Lenovo is warmest on the right-hand side compared to the left-hand side of the Gigabyte and the more symmetric surface temperatures of the Dell. For gaming purposes, however, having the frequently used left side of the keyboard remain cool may be preferable.

Battery Life

The battery capacity of the XPS 15 is 30 percent higher than its two competitors and runtimes are subsequently longer by more than just a couple of hours under similar WLAN conditions. Otherwise, the Lenovo and Gigabyte are almost identical in battery life even though the latter is equipped with a much more powerful GPU.

All battery packs are integrated and cannot be easily swapped.

Verdict

The new XPS 15 is an excellent balance between work, travel, and play while P55W sacrifices some portability for graphics performance and a more tactile keyboard.
The new XPS 15 is an excellent balance between work, travel, and play while P55W sacrifices some portability for graphics performance and a more tactile keyboard.

Between the XPS 15, Ideapad Y700, and Gigabyte P55W, the Dell notebook is by far the more versatile choice because of its lighter weight, smaller size, and longer runtimes while carrying the same powerful CPU and GPU as the Lenovo. After all, there's a reason why the recent XPS 15 9550 sits high atop our Top 10 list of multimedia notebooks. It's difficult to recommend the Lenovo over the Dell even after taking into account the limited connectivity options, warmer temperatures, and lack of a Numpad on the XPS system.

The Gigabyte is in a performance class of its own with its more powerful (and demanding) GTX 970M and plethora of connectivity options. Battery life doesn't suffer compared to the Lenovo and the unit is even lighter as well, but fan noise, core temperatures, and size are all inflated. Its excellent keyboard tactility and feedback shouldn't be ignored as it feels even more comfortable to use for word processing than on the Dell.

The more well-rounded notebook is indeed the XPS 15 especially for users who game as much as they travel and work. Otherwise, the Gigabyte P55W is the larger and more powerful option with longer legs as a gaming and multimedia machine.

After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
