Dell G7 15 (7588) Review: A hex-core gaming laptop that will not break the bank

Credit: Adam Patrick Murray / IDG

Dell G7 15 is a medium sized playable laptop with GTX 1060 Max-Q graphics, medium battery life, and you guessed it – a Mid-range price tag of $ 1200. But this The system has a fantastic feature that separates it from the crowd: a hex-core, benchmark-smashing Core i7 processor that will tense content creators. In fact, the overall performance of the G7 15 is just a step or two behind it for our current 1

5-inch playable laptop, the thinner and easier MSI GS65 Stealth Thin 8RE, while it costs around $ 600 less. Among our quibbles: a weak display and an even too hot chassis.

This review is part of our best portable laptops. Go for details about competing products and how we tested them.

Price and Specifications

We tested the $ 1,199 model on the Dell G7 15 (Model 7588), which comes with Intel's hexadecore Core i7-8750H processor, 16GB DDR4 RAM, a 128GB solid state boot drive, and a traditional 1TB hard drive for data. With a total of 12 treatment threads (thanks to Intel's Hyper Threading technology), the G7 15 packs in an eye of multitasking power, as we see when we reach our benchmarks.

On the visual side, the G7 15 has a 15.6 inch anti-glare full HD (1920×1080) IPS technology display, plus a Nvidia GeForce GTX 1060 processor with 6GB GDDR5 RAM and Max-Q design (which puts one cover on performance to reduce power consumption and heat output). When sitting in the middle of Nvidia's GeForce GTX 10 Series card, the GTX 1060 with Max-Q provides reliable 60fps and up to most current top games.

You can knock around $ 120 of the G7 15 Review Unit price tag by snapping up a 8GB RAM instead of 16GB, while the most demanding version switches into a hoist, overclockable hex-core i9-8950HK processor. There is also a G7 15 laptop with a 4K display (plus standard i7-8750H CPU) for $ 1,499. In addition, all laptops come in the Dell G7 15 Series with the same GTX 1060 graphics card with Max-Q design.


Meets 15.32 x 10.82 x 0.98 inches and weighs a significant but not prohibitive 6 pounds, 4 grams or 7 pounds, 2 ounces with the 180 watt AC power adapter, makes Dells G7 15-staple paradoxically it feels thinner than you expect. That said, the G7 made a tight hug in my 15-inch portable purse.

The twin-cooling valves on the back of the Dell G7 15 look supported, yet amazing.

Available in the flavors "Licorice Black" and "Alpine White" (we tested the Alpine White variety), the Dell G7 15 has a sporty but underrated look. Clearly, some insignificant lid is offset by an oblique front edge that has a sharp black grille, while the two cooling valves in the back look elegant and powerful.

Opening the lid reveals a relatively thick edge ring (about three quarters of a inch along the top and sides, plus an inch bottom) around 15.6-inch screen, plus a smooth, jet-black palm rest slightly pushed around the keyboard .


Dell G7 15 is non-touch, 1920×1080 display has solid viewing angles. The screen dimmes around 45 degrees from the sides, top and bottom, without signs of inverse colors that you might see on a cheap laptop screen. There is quite a lot for the course when it comes to an IPS screen like the G7.

  Dell G7 15's 15.6-inch IPS display gives good viewing angles, but we wish it was brighter. </p>
<p>  While the viewing angle of the Dell G7 15 looks good, the same can not be said for brightness. Measuring only 234 nits (or candela), G7's screen brightness drops slightly short of the 250-nits minimum we prefer. In an office setting or a cave, the G7 15's dimming screen is not a big problem, but I was having trouble making one of the darker levels in <em> Diablo 3 </em> while I was playing near a bright window. 19659008] Keyboard, Touchpad, Speakers, Webcam </h2>
<p>  The Dell G7 15s chiclet style keyboard is the standard space laptop hazard, with smooth flat keys, decent travel and a nice tactile bump in the middle of each keystroke. The outlined WASD keys made their respective jobs under play, nor impressed me or got in my way. A 10-digit numeric keypad is on the right, while default feature-enabled shortcuts such as screen lock, search, brightness, media playback, and flight mode are also pressed. G7 eschews fancy LED backlighting systems for a basic two-step blue glow. </p>

Nothing about the Dell G7 15's backlit keyboard game "game" except outlined WASD keys.

Stationed slightly to the left of the center to keep it right below the spacebar, the Dell G7 15's medium-sized trackpad swapped on my swipes with minimum jitter, while avoiding erroneous inputs from my palms. Clicking feels a little stiff, as usual, but it should not play much for players, who probably want to use mice most of the time.

Although they are not a substitute for a good pair of headphones, the Dell G7 15 Top-firing speakers are a tiny cut over tinny, bass-deprived speakers are found in most laptops. The music sounded relatively detailed without collapse in mush. While you should not expect any big beats, you will at least hear a hint of bass. You can also hover G7 speakers to an impressive high volume, a good thing, as it turns out, because cooling fans tend to spin up to a roar during graphically intense games. (More about G7 15's heat problems in a moment.)

Video taken by the Dell G7 15 webcam (the lens is located in the upper part of the display) typically looks grainy and speckled, but of true contrast and color. While G7's webcam is good for Skype, players who want to make waves on Twitch will do better with a dedicated lens.


The Dell G7 15 comes with a solid range of ports, starting left with an Ethernet port, USB 3.1 Gen. 2 Type-A, and an SD memory card reader. Also on the left side: a Noble Lock security gate and a barrel power-in port.

On the right side of the G7 15 you will find HDMI 2.0, a Thunderbolt 3 port, two USB 3.1 Type A ports (with PowerShare) and a combo audio jack.

General Performance

While the Dell G7 15s GTX 1060 Max-Q video card provides the middle range of graphics performance, it is expected with average graphics performance. Hex-core CPU-among the first we've seen in a relatively thin playable laptop, although we can expect many more in the near future, some impressive numbers alternated, perfect for players who wan t to take a break from shooting things to create other things.


In our first reference, we use the Free HandBrake tool to encode a 40GB video file in an Android tablet compatible format. It's a CPU-intensive job that can take an hour or more to complete and it tends to spin cooling fans in the process. Although a good HandBrake score does not necessarily correspond to star games (we're coming to game performance in an instant), it's good for YouTube content creators, Twitch broadcasters, or anyone else who plans multitasking during gaming. [19659010] dell g7 15 7588 handbrake "border =" 0 "data-imageid =" 100770761 "data-license =" idg "height =" 421 "src =" https://demo.idg.com.au/idgns/ images / 2db7e84952-dell-g7-15-7588-handbrake-100770761-large.jpg "width =" 700 "/> Melissa Riofrio / IDG

The Dell G7 15 chewed through our handbrake benchmark thanks to the fast i7-CPU witch core.

Most core processors generally do better with HandBrake, and yes, the Dell G7 15 and witch core Core i7-8750H CPU break it out. In fact, with its handbrake in 2.035 seconds, or just a little over half an hour, the G7 15 only runs the same witch core MSI GS65 Stealth Thin 8RE, a razor-sharp gaming laptop that costs $ 600 more.

The Next Fastest Competitor In Our Comparison, Dell G3 15 With A Quad-Core I5-8300H processor, took another 10 minutes to complete the handbrake test, followed by a number of Core i7-7700HQ powered laptops, which demonstrated the difference they extra kernels do when it comes to CPU-intensive tasks.


Next up, our Cinebench test involves another stressful computing: delivering a 3D image in real time. Because Cinebench takes just a few minutes to perform, it gives us a good idea of ​​how a particular laptop handles short outbreaks of intense activity. We run Cinebench in both multi-threaded and single-thread modes, practical to illustrate the performance benefits of multiple cores and threads.

  dell g7 15 7588 cinebench2 Melissa Riofrio / IDG

The Dell G7 15's Cinebench score shows the difference six power processor cores compared to four.

It is not surprising that the 12-threaded Dell G7 15 shines when it comes to Cinebench's multi-threaded test, once again a score just behind it on the MSI GS65 Stealth Thin 8RE while vacuuming its quad-core competition. We are also pleased with Dell's top list results.

(Note: The results for Gigabyte Aero 15X, a system set in other charts in this story, were not available for this test.)

Gaming performance

We launch game tests with FireStrike Extreme, a synthetic reference goal which is not directly translated into game performance, but still gives us a good baseline for comparisons.

  dell g7 15 7588 3dmark firestrike Melissa Riofrio / IDG

The Dell G7 15's middle GTX 1060 video card leaves the unnecessary middle of the package with regard to FireStrike Extreme.

Dell G7 15s FireStrike Extreme scores land in the middle of the package, giving perfect sense given the GTX 1060 with Max-Q. The top two finishers in our chart, the MicroCenter PowerSpec 15 and the Gigabyte Aero 15X P65Q, boasts more powerful GTX 1070 cards, while most laptops running Dell have GTX 1050 GPUs. The MSI GS65 Stealth Thin 8RE with a similar GTX 1060 card (albeit with a full-fat configuration, compared to G7's powerful Max-Q design) achieves a slightly better FireStrike Extreme score than the G7 15, but as we will see in a moment , does not make a big difference when it comes to real-time games.

( Note: Results for HP Omen 15-ce0xx, a system set in other charts in this story, was not available for this test.)

Real-time game talk let's begin with 2013 Tomb Raider reboot, a game that borrows a bit more on CPU power than newer titles. [19659010] dell g7 15 7588 Tomb Raider "border =" 0 "data-imageid =" 100770766 "data-license =" idg "height =" 421 "src =" https://demo.idg.com.au/idgns /images/2e2125d835-dell-g7-15-7588-tomb-raider-100770766-large.jpg "width =" 700 "/> Melissa Riofrio / IDG

Without a GTX 1070 or better video card, the frames for the Dell G7 15 Tomb Raider Fixed in the 90 Series.

] We expect a laptop with a GTX 1060 video card to squeeze a Tomb Raider frame rate somewhere on 90's and that's pretty much what we got from the Dell G7 15. While the GTX 1060-powered MSI GS65 Stealth Thin 8RE enjoys (as we just saw) a small FireStrike Extreme advantage over the G7, it's just a modest Tomb Raider Frame Load over Dell (97.2 fps versus 92.7 fps). To see a more significant increase in Tomb Raider frame rates, you need to cough up more for a notebook with GTX 1070 or better graphics, for oak form the MicroCenter PowerSpec 15.

We look more of the same with Middle-Earth: Shadow of Mordor . All GTX 1060 Max-Q powered laptops in our chart – including the Dell G7 15 – were gathered approximately in the 80-90 fps series, while a few laptops with full GTX 1060 graphics saw a modest bump of 90-100 fps .

  dell g7 15 7588 middle earth Melissa Riofrio / IDG

As with Tomb Raider, the GTX 1060-powered Dell G7 15's Middle Earth: Shadow of Mordor image frequencies [19659013] For Shadow of Mordor frame rates above 120, you generally have to go up to a GTX 1070 system or better graphics.

] Finally, we fired up Rise of the Tomb Raider, a graphically intense title that requires at least GTX 1060 graphics to achieve a steady 60 fps.

  Dell G7 15 and GTX 1060 The Max-Q video card can swing <em> Rise of the Tomb Raider </em> over 60 fps, but just just. </p>
<p>  Th e Dell G7 15 and GTX 1060 Max-Q graphics are a solid 68.5 fps while the correspondingly equipped Acer Predator Helios 300 and MSI GS65 Stealth Thin 8RE are in the same ballpark with 72.1 and 70, respectively, 7 fps. Gaming laptops with GTX 1070 or better graphics (like MicroCenter PowerSpec 15) can beat more than 100 fps from <em> Rise of the Tomb Raider </em> while sub- $ 1000 GTX 1050-powered laptops like Dell's own G3 15 usually settles for between 30-45 fps. </p>
<p>  Well, a word about heat. While I was playing <em> Rise of the Tomb Raider </em> I noticed that the cooler lifts from the Dell G7 15 were roaring and the chassis got uncomfortable heat, especially near the top of the keyboard and a bit to the right. In fact, the 7, 8 and 9 keys were so hot that they felt that they burned their fingertips. </p>
<p>  After about an hour at <em> Rise of the Tomb Raider </em> I check G7's CPU packet temperature and got a reading at 98 degrees Celsius (208 degrees Fahrenheit), warm enough to boil water and only two degrees shy of Core i7-8750H's maximum operating temperature. The CPU has also occupied thermal gas jam several times to cool things. </p>
<p>  So has the Dell G7 15 a cooling problem? Not necessarily. Yes, the G7 runs hot, but the CPU packet temperatures are within Intel's specifications. Also, Nvidia's Max-Q specification is meant to push as much GPU power as possible in the smallest possible space, which means that temperatures are bound to rise. I also want to point out that the G7 15 ran a bit cool while playing less graphically demanding titles like <em> Diablo 3 </em> and <em> World of Warcraft </em> (a game that maps buttons 7, 8 and 9 to different spellings and abilities). </p>
<p>  Nevertheless, G7's tends to run hot an unfortunate life situation for lap top notebooks so thin and lightweight (relatively, anyway) like this. </p>
<h2>  Battery Life </h2>
<p>  You can not expect all-day battery life from a laptop, but the Dell G7 15 and 55-watt battery makes a good job of staying alive without the help of the big AC adapter. </p><div><script async src=

We test the battery life of a laptop by solving a 4K video using the Windows 10 Movies and TV app store, with the screen brightness set to approx. 250 nits (as in the G7 15 case meant brightness all the way up) and volume dialed to 50 percent, headphones plugged in.

  Dell G7 157588 battery life is relatively solid given its 55 watt-hour battery. </p>
<p>  Dell G7 15's 332 minute performance (about 5.5 hours) is not as shabby for a playable laptop landing in the middle of the pack of about the same battery life as the cheaper Dell G3 15, the older Dell Inspiron 15 7000 Gaming and it swallowed the MSI GS65 Stealth Thin 8RE. Specifically, the 5.5 pound Acer Predator Helios 300 hugs more than an hour of extra life out of its slightly smaller 48 watt-hour battery, and it's despite the full GTX 1060 video card. The roundup laptop with the best battery life, the Gigabyte Aero 15X P65Q (which contains a powerful hungry 4K display), has a massive 94 watt-hour battery. </h2>
<p>  Conclusion </h2>
<p>  Armed with a screaming fast hex-core CPU and a pretty powerful graphics card, the $ 1200 Dell G7 15 packs an impressive amount of processing and gaming power in a shell less than an inch thick. Players looking for the highest possible frames will find better value in a quad-core laptop with a steeper GPU, while those searching for a thinner and easier hex-core gaming laptop should check out the precious MSI GS65 Stealth Thin 8RE . But if you're on a budget and want enough CPU power to stream or make videos while playing, the G7 15 (for now, at least) is a tempting, affordable choice. </p>
