Dell Inspiron 15 7000 7577 (i7-7700HQ, GTX 1060 Max-Q, 4K UHD) Laptop Review

4K overkill. We check out the popular 15.6-inch mainstream gaming notebook from Dell for a third time in yet another configuration. As impressive as the GTX 1060 Max-Q may be, it just isn't the best GPU for 4K gaming.

Take a step outside of Dell's Alienware series and gamers will start to venture into the budget-mainstream category of notebooks like the Inspiron 15 7577. The system promises a lot for under $1000 USD including GTX 1060 Max-Q graphics and Thunderbolt 3 while higher-end SKUs throw in 4K UHD with more RAM and storage for an additional $500 USD. Our test unit today is the latter with its Core i7-7700HQ CPU and 4K UHD panel instead of the i5-7300HQ CPU and FHD panel, respectively. Is the hefty investment in 4K worth the steep price of entry?

We recommend checking out our existing reviews on the Inspiron 15 7577 as more details on the chassis and its features can be found on these pages. For this particular review update, we will analyze the advantages and disadvantages of the 4K UHD panel and what games pair best with the GTX 1060 Max-Q at this demanding resolution. The Inspiron 15 gaming series competes directly against mainstream gaming notebooks like the Gigabyte Sabre 15, Acer Aspire Nitro, MSI GP62, and the Asus FX553.

Case

The base continues to be relatively strong for the price with light flexing and creaking when attempting to twist or bend it. The lid could have been more rigid and the inner bezel of the screen is not completely flat yet again for a second time in a row, so this is definitely an area where the manufacturer can improve upon for future revisions of the model.

The Dell unit is still quite the heavyweight even for a gaming notebook due in part to its thick skeleton. Other 15-inch notebooks with similar-performing GPU options like the Lenovo Legion Y520 or MSI GF62VR are several hundred grams lighter and slightly smaller in footprint.

Connectivity

The Thunderbolt 3 port is the highlight of the system's connectivity options. Such a feature is typically reserved for higher-end gaming systems that can easily cost hundreds more whereas the Inspiron 15 7577 can start for under $1000 USD.

SD Card Reader

The card reader is where Dell had to cut some corners. A fully inserted SD card protrudes about half its length and transfer rates are just a fraction of most Ultrabooks and other gaming notebooks.

Input Devices

Keyboard and Touchpad

The Chiclet keyboard come standard with a red backlight of two intensity levels. The dark red letters contrast poorly with the black key caps and so the backlight is recommended even if under well-lit conditions. Key feedback is both softer and lighter than the same keys found on the MSI GS or GF series or the XPS 15 series.

The trackpad is slightly textured with reliable cursor control and multi-point inputs. Its integrated mouse keys are shallow in travel, spongy in feedback, and generally less impressive than the trackpads on MSI systems.

Display

Right off the bat, our measurements show that the 4K UHD panel is brighter and with a wider color gamut than the lower-end FHD SKU while retaining relatively equal black-to-white response times in the process. In short, videos are texts are not only crisper, but also brighter and more vivid for a superior video playback experience. The screen is slightly grainy as is common on most matte panels, but it is thankfully not significant enough to be distracting during use. Likewise, uneven backlight bleeding is present and only noticeable if on high brightness settings and with black borders.

This particular 4K UHD AU Optronics B156ZAN panel is found on no other notebook in our database.

* ... smaller is better

Color space covers nearly the entire sRGB spectrum and approximately 63 percent of the AdobeRGB standard. Graphics artists are more likely to appreciate the wider range of colors offered by the 4K UHD option over the FHD option. Other notebooks with 4K UHD panels like the XPS 15 or Razer Blade Pro tend to cover sRGB in its entirety.

Calman measurements reveal a generally inaccurate grayscale out of the box. Our calibration attempts noticeably improve both grayscale and colors on all tested saturation levels and we recommend applying our ICM color profile above to get the most out of the 4K UHD panel. Blue, unfortunately, is represented more inaccurately than other colors even after calibration.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
28.4 ms ... rise ↗ and fall ↘ combined↗ 16 ms rise
↘ 12.4 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 65 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (25.6 ms).
       Response Time 50% Grey to 80% Grey
35.2 ms ... rise ↗ and fall ↘ combined↗ 17.2 ms rise
↘ 18 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 26 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (41 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9247 (minimum: 43 - maximum: 142900) Hz was measured.

Outdoor visibility is better than the FHD model since the 4K UHD panel is brighter and able to reproduce deeper colors. However, text scaling should be enabled or else the denser PPI will prove disadvantageous in terms of readability. Viewing angles are still wide and with no major color shifting even if at extreme angles.

Performance

The Core i7-7700HQ is common across most newer gaming notebooks from models as small as the Razer Blade up to the large MSI GT75VR. The GTX 1060 Max-Q GPU is much rarer and is currently the highest option for the Inspiron 15 7577. Older Inspiron 15 7567 SKUs were limited to the GTX 1050 and GTX 1050 Ti only.

Processor

Multi-thread CPU performance is approximately 44 percent faster than the i5-7300HQ in the lower-end Inspiron 15 7577 SKU. Running CineBench R15 in a loop results in steady scores over time to suggest no processor throttling over long periods.

See our Core i7-7700HQ CPU page for more technical information and benchmark comparisons.

System Performance

PCMark 10 benchmarks rank the Dell within single-digit percentage points from the average gaming notebook and even the lower-end Inspiron 15 7577 SKU with the slower Core i5-7300HQ. As long as the system is equipped with a primary SSD, the Inspiron will feel snappy for everyday loads regardless of the CPU or GPU option.

Storage Devices

Our configuration utilizes a primary SK Hynix 128 GB M.2 SSD and a secondary Seagate 1 TB HDD. This particular SSD is limited to SATA III speeds unlike the NVMe SSDs on higher-end configurations of the Dell. Transfer rates from the SK Hynix drive are below average for a SATA III HDD as sequential write rates are about half of what some competing SATA III SSDs have to offer.

See our table of HDDs and SSDs for more benchmark comparisons.

GPU Performance

The GTX 1060 Max-Q is about 10 percent slower than the standard GTX 1060 for laptops according to 3DMark benchmarks. Choosing the Max-Q option over the GTX 1050 Ti configuration will net users a rough 25 to 30 percent boost in GPU power while the jump from the GTX 1050 would be even larger at 70 to 115 percent depending on the resolution.

Gaming Performance

The additional horsepower provided by the GTX 1060 Max-Q over the GTX 1050 or 1050 Ti allows users to play modern titles at 1080p60 at Medium to High settings. Less intensive titles like Overwatch or DOTA 2 will perform even better and have more impressive results at the native 4K UHD resolution. Unfortunately, most titles perform poorly at native 4K UHD including Rise of the Tomb Raider and Destiny 2. The GTX 1060 Max-Q pairs best with FHD panels much like on the original GTX 1060.

See our dedicated page on the GeForce GTX 1060 Max-Q for more technical information and benchmark comparisons.

Stress Test

We stress the notebook with synthetic benchmarks to identify for any throttling or stability issues. When subjected to Prime95 loads, we can observe a steady CPU clock rate and temperature of 3.2 GHz and 67 C, respectively. Running both Prime95 and FurMark will impressively result in a steady CPU temperature of 83 C without affecting clock rate. Core CPU and GPU temperatures are quite low at under 70 C when gaming for extended periods.

Much like our other Inspiron 15 7577 configurations, running on battery power will limit CPU and GPU performance and so AC power is recommended when gaming.

Emissions

System Noise

Fan behavior is not dissimilar to the lower-end Inspiron 15 7577 SKUs despite our system carrying a faster GTX 1060 Max-Q GPU. Both system fans remain idle during low processing loads for near-silent operation save for the barely audible HDD. Gaming loads will bump fan noise up to 40 dB(A) as defined by Nvidia's stringent Max-Q specifications. Gaming for longer periods, however, may induce faster RPMs. For example, running Witcher 3 for just 10 to 15 minutes resulted in a noticeably louder fan noise of 44 dB(A). Although not as loud as most thin-and-light gaming notebooks where 50 dB(A) is attainable, we would've preferred an option for slightly warmer core temperatures if it had meant quieter fan noise since the processors have some thermal headroom as our Stress Test section shows.

Our specific unit suffers from no coil whine or electronic noise.

Temperature

Surface temperatures around the palm rests, NumPad, and WASD keys remain relatively cool no matter the onscreen load due to the positioning of the cooling solution underneath. The hot spots are generally away from where users are more likely to touch.

Surfaces never become uncomfortably warm when gaming so long as the rear third of the notebook is properly set on a table and not one's lap. Be sure to leave ample space behind the notebook for ventilation.

Energy Management

Power Consumption

When gaming, the Dell consumes just a few percentage Watts more than the GTX 1050 version of the same model and even competing systems with the GTX 1050 Ti like the Asus Zenbook Pro UX550VE. Considering that the GTX 1060 Max-Q offers a significantly larger boost in graphics performance than either of these GPUs, the very slight increase in power consumption seems to be a very fair trade off.

Running extreme loads at 100 percent CPU and GPU utilization will demand 130 W from a medium-sized AC adapter (~15 x 8 x 3 cm) rated for up to 180 W. This maximum sits comfortably between the GTX 1050 and GTX 1060 when all are subjected to similarly extreme loads.

Battery Life

Runtimes are shorter on the higher-end 4K UHD GTX 1060 Max-Q SKU compared to the lower-end FHD GTX 1050 SKU by about an hour when subjected to similar WLAN conditions. Users can expect about 5.5 hours of real-world WLAN use out of this configuration to be respectable for a gaming notebook.

Verdict

In review: Dell Inspiron 15 7000 7577 4K UHD
In review: Dell Inspiron 15 7000 7577 4K UHD

For gaming purposes, a native 4K UHD panel is not the perfect fit for a system powered by the GTX 1060 Max-Q GPU. Unless if the notebook will be used exclusively for large spreadsheet work or undemanding games like Rocket League, LoL, Overwatch, or DOTA 2, then it becomes difficult to justify the exorbitant price premium of the 4K UHD panel over the standard FHD model. Users will need a much more powerful GPU to better exploit what 4K UHD has to offer.

If the above is not concerning, then potential buyers will be pleased to find that the 4K UHD panel is indeed brighter than the FHD model and with more accurate colors to boot. The same advantages and disadvantages of our existing Inspiron 15 7577 pages continue to apply here including the strong but heavy base, soft but quiet keyboard keys, and accessible internals.

The 4K UHD version of the Inspiron 15 7577 is superior to the FHD SKUs on paper, but gamers will be better off playing most titles at 1080p for which the GTX 1060 Max-Q was designed for.

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.
