ASUS ROG G752 (+ G-Sync) review – the upgrade that makes this machine worthwhile lies under the hood


ASUS’ ROG series has been killing on the gaming notebook market segment but in the last couple of years, more and more alternatives start to pop out beside the hard time the Taiwanese company gets from Alienware. This year even Acer released its premium Predator offering in the high-end gaming class so it will be quite interesting to see if the new ROG G752 has what it takes to take on the competition.

Of course, the new ROG flagship doesn’t fall behind its competitors in terms of performance since it delivers a choice between Core i7-6700HQ and the overclockable Core i7-6820HK while, on the GPU front, there are configurations with GeForce GTX 965M, 970M, and 980M. However, we are very pleased to see another M.2 PCIe SSD slot in addition to the old one. And, of course, the additional RAM slots that allow up to 64GB of DDR4-2133 RAM. Last, but not least, the chassis has also been revamped yet keeping the old concept. The teardown revealed almost identical cooling system design and construction. That’s not necessarily bad, especially when considering the fact that the old ROG G751 did perfectly in our temperature tests. So what’s new and what’s old?

Retail package

We are not sure what ASUS has in stored for us this time because the unit we used for reviewing was a testing sample and the full retail package wasn’t at hand.



Design and construction

In terms of design and overall appearance, we can say it’s a big leap forward. It’s not the usual ROG design and it’s quite refreshing to see a different choice of color palettes and appearance. However, the rigidity of the chassis and choice of materials doesn’t seem to be better than last year’s ROG G751.




For starters, the lid is now fully covered in aluminum with ASUS’ backlit ROG logo in the middle and two orange LED stripes on each side. The plate bends a little under pressure but no matter how much pressure we applied to the lid, there were no ripples on the LCD screen on the other side. The hinges are okay and the lid lifts up easily without using both hands. There’s also a small plastic bezel on the top of the lid and that’s where the Wi-Fi antennas reside, for better reception, of course. In contrary to the top cover, the bottom piece is entirely made of plastic that imitates aluminum. You can easily distinguish the opening for the subwoofer, two grills on the service cover, which is detachable and gives access to two of the RAM slots, 2.5-inch drive, and the two M.2 PCIe SSD slots. In addition to all those things, there’s a neat transparent plastic cover that lets you peek into the internals, but you will mostly see a part of the heat pipes and two fans. It’s cool, but it’s on the bottom so you will not see it most of the time.






This time around, ASUS was able to trim down the profile of the machine by a fair margin. The new ROG G752 now has 48.26 mm thin profile from 53.00 mm height. Nevertheless, ASUS’ port placement isn’t that good this time – we’ve got almost all ports crammed in the right side where the cables might obstruct normal mouse usage. We’ve got the LAN, HDMI, mini DisplayPort, two USB 3.0, USB 3.1 (Type-C) and three 3.5 mm audio jacks for microphone, headphones etc. There’s also the DC charging port while the left side only has the optical drive, SD card reader, and two USB 3.0 ports. The back side of the machine features the iconic exhaust vents. This year’s version has vents that look more like an exotic sports car and have cool red LED light in the middle. There’s also that plastic gold-colored plastic piece between the hinges.



In contrary to the overall change in the design, the interior somehow doesn’t go too far from last year’s G751. It has the same matte, soft-touch finish around the keyboard and touchpad, but there are a few aluminum-like elements around the edges. The design of the power button also seems pretty cool, blends perfectly into with the design signature. Unfortunately, though, these elements are plastic imitating brushed-aluminum. The real thing would have been better, especially with last year’s version. The teardown also revealed that the G751 had slightly better choice of materials and felt sturdier than today’s variant.

The keyboard has also been changed, but for the better. Two more macro keys are added and now they don’t interfere with the keyboard – they are spaced apart and they are easily distinguished. But the overall feel of the buttons hasn’t got any major changes – the keys still offer long key travel (same as before 2.5 mm), they are well separated from each other, the WASD and arrow keys are highlighted, easy to find and the LED keyboard offers three levels of brightness as well as supporting rollover up to 30 keys. We are also pretty disappointed that the engineers at ASUS still haven’t included the media player buttons into the keyboard and the volume keys are still too far from the “Fn” key so lowering or increasing the volume has to be done with both hands. As for the touchpad, it’s quite comfortable – no significant changes here – the mouse buttons are the same and so is the surface of the trackpad.





We are left with mixed feelings about the new G752’s overhaul. While it gives a breath of fresh air to the old ROG flagship series with totally different design and choice of colors, it doesn’t meet our expectation in terms of rigidity. Only the lid is made of aluminum and the keyboard tray sinks when little pressure is applied. At least, this doesn’t affect the performance of the keyboard. It’s hard not to mention that the machine now weighs more than its predecessor while incorporating more lightweight plastic – 4.31 kg for the new G752 and 4.05 kg for last year’s G751. Moreover, ASUS haven’t changed the placement of the ports that may get in the way for some of users.

Disassembly and upgrade options

Just like its predecessor, the G752 offers a fair amount of upgrade options. You can take advantage of the 2.5-inch HDD/SSD slot, which is occupied by the stock HDD most of the time, 4x RAM slots supporting up to 64GB of DDR4-2133 RAM and two M.2 PCIe NVMe SSD slots support 2280 standard with M-edge key connectors. You can check out our article regarding the full disassembly of the machine and a bit more about the build.



Display and sound

The notebook comes with Full HD AH-IPS panel manufactured by LG Display with model number LP173WF4-SPF3. Most probably, this is a revised third version of the panel that we found in the old G751JY with G-Sync. And, of course, this one packs the G-Synch chip as well. Moving on – the panel measures at 17.3 inches with 1920 x 1080 resolution, 16:9 aspect ratio, 127 PPI and 0.199 x 0.199 mm pixel pitch. It can be considered as retina if viewed from a distance equal or greater than 69 cm.

Micr-ASUS ROG G752

Since this is an IPS panel, the display offers excellent viewing angles from a 45-degree angle.

Angles-ASUS ROG G752

We were able to detect 334 cd/m2 maximum screen brightness with only 12% deviation. Both results are excellent and the display will perform well even under bright light source. The color temperature on white screen is 7250K – a bit cooler than the optimal 6500K but still okay. Also, there’s a small deviation on the upper-right of the screen.

BefMax-Brightness-ASUS ROG G752

ASUS has included a so-called ASUS Splendid Technology for easy setup of the display. There are several presets for you to take advantage of, for different purposes, of course, but we used “Normal” for our tests.

Color reproduction

To make sure we are on the same page let’s have a little introduction into the sRGB and Adobe RGB color gamuts. The CIE 1976 Uniform Chromaticity Diagram represents the spectrum of colors visible to the human eye, thus giving you a better perception of color gamut coverage and color accuracy. Inside the black triangle, you will see the standard color gamut (sRGB), used by millions of people in HDTV and on the Web. As for Adobe RGB, it is used to work with professional cameras and monitors when preparing print. Basically, colors inside the black triangle are used by everyone, and so reproducing them accurately is key in a quality display.

Although the panel doesn’t have perfect sRGB coverage, we consider the result still pretty good – 90% of the sRGB color gamut is covered. This will ensure relatively accurate color reproduction and vivid colors.


The graph below is the same but with recorded results and the colored circles represent the reference colors, the white circles being the result. You can see the main and additional colors with 100% and 50% saturation inside the sRGB gamut.

The gamma curve aligns perfectly with the optimal 2.2 after calibration.

We tuned the display at 140 cd/m2 and 6500K color temperature.

We used X-Rite i1Display Pro for calibration.

xRite-ASUS ROG G752

We tested the display using 24 commonly used sample colors like skin tones, grass, blue sky, orange etc. After profiling, the display had an average DeltaE 2000 deviation of only 0.69, while the contrast was 1030:1 before and 870:1 after calibration. Excellent results.

Here’s another batch of colors that we’ve tested.

ColorChecker-ASUS ROG G752

Pulse-width modulation (PWM, Screen flickering)

Great news here. Since the panel is actually an updated version of the old one, the display doesn’t use PWM for adjusting brightness and the G-Sync enabled displays we’ve tested so far lack the so-called screen flickering effect.



Once again the panel used for the flagship ASUS ROG series doesn’t disappoint. While it’s far from the sRGB color gamut coverage (90%) that the Acer Predator offers (100%), the G752 holds several key advantages over its competitors. For starters, the G752’s display has integrated G-Sync chip allowing smooth gameplay on-the-go instead of relying on an external monitor support like the Predator. Also, the refresh rate of the panel is 75 Hz and that’s a considerable perk for gamers. And it’s also a better choice compared to the 15-inch Dell Alienware, which didn’t do very well in our tests.

Anyway, back to the G752. It still lacks the PWM across all brightness levels (harmless to one’s eyes), has high contrast ratio, fairly accurate color reproduction, and high maximum brightness. It’s not perfect, but it will do an excellent job for gaming, multimedia etc.


As its predecessor, the G752 incorporates a G-Sync chip for smooth gameplay even at the higher settings on demanding games. You can read all about the technology here:

Screen comparison

If we assume a distance of 58cm (~23in) between the human eye and the notebook monitor, then normal (20/20) vision would require a pixel density of at least 150ppi in order to interpret an image as perfectly detailed.

Again ASUS has included a subwoofer at the bottom to aid the main loudspeakers and make the multimedia experience fuller. Our tests confirm the initial thoughts we had about the sound system. The sound is crisp and full in low and mid frequencies and there’s little distortion in the high frequencies.

The machine came with pre-installed Windows 10 (64-bit) but if you want to perform a clean install of the OS, we suggest downloading all the needed drivers from ASUS’ official support page:

The notebook also comes with pre-installed so-called ROG Gaming Center that gives you geeky stats like CPU and GPU frequencies, temperatures, and memory status. You can also customize different profiles depending on the game you currently play with preset profiles of the macro keys as well.

Unfortunately, the new unit has significantly lower battery capacity and this will affect the endurance of the machine for sure. Last year’s version features 8-cell 88Wh battery while the G752 incorporates only 6-cell 66Wh while packing roughly the same components. Only the motherboard and CPU are newer generation promising better power consumption, but we doubt this much capacity can be compensated. Moreover, we discovered that the notebook excludes the iGPU and thus the machine doesn’t have switchable graphics feature. This means that the discrete GPU will take care of all GPU-related tasks and consuming more energy in the process.

We ran the usual test with the following settings: Wi-Fi turned on, power saver mode turned on and screen brightness set to 120 cd/m2.

Web browsing

In order to simulate real-life conditions, we used our own script to automatically browse through over 70 websites.


Disappointing but expected result due to the smaller battery capacity – 195 minutes (3 hours and 15 minutes).

Video playback

For every test of this kind, we use the same video in HD.


Still falling behind its predecessor – 218 minutes (3 hours and 38 minutes).


For accurate simulation, we used the Metro Last Light benchmark running on a loop with graphic settings set to minimum.


We doubt you will start a gaming session away from the charger but here’s how much time you will get out of the system – 95 minutes (1 hour and 35 minutes).


Intel_Core_i7_logoIntel Core i7-6700HQ represents the Skylake H family and it’s considered a high-performance chip with high voltage – 45W TDP. This is a step down from its direct predecessor – Core i7-4700HQ, but matches its short-lived predecessor Core i7-5700HQ. The Core i7-6700HQ has four cores ticking at 2.6GHz and can go up to 3.5 GHz for one active core and 3.1 GHz for four active cores. The silicon supports the so-called Hyper-Threading technology that emulates one virtual core for each physical, thus establishing a total of 8 threads.

Furthermore, the chip is manufactured using a 14nm FinFET process and integrates Intel HD Graphics 530 GPU with 24 EU (Executable Units) clocked at 350 – 1050 MHz. The memory controller supports up to 64GB of DDR3 or DDR4 RAM at 1600 or 2133 MHz respectively. The CPU is suitable for heavy applications and gaming.

The two-staged temperature test doesn’t translate into real-life usage since it’s quite unlikely that the general user would reach 100% CPU and GPU load, but we continue to do this test because it’s a good way to determine the overall stability of the machine under heavy load and how the cooling system handles higher temperatures.

Before we started the CPU stress test, we recorded idle temperatures around 35-36 °C and after we started the test, the silicon reached around 90 °C for a brief time and then the fans cooled the chip down to 73-77 °C. We would like to note that there wasn’t any throttling and the machine ran pretty quietly without moving away from the 3.1 GHz mark – this is the maximum operating frequency for four active cores. You can see the red and green line below representing the temperatures and CPU load, respectively.

g752 cpu

After an hour had passed, we switched on the GPU stress test as well. The silicon’s temperatures rose and reaching as high as 95-97 °C, but even then the chip maintained operating frequency between 3.0 GHz and 3.1 GHz while the GPU ran pretty cool as well – reaching a maximum of 74 °C without any throttling issues.

g752 goy

We also measured the temperatures on the surface and again the G752, just like its predecessor, passed our test with flying colors. We are pleased with the results and the fact that engineers at ASUS have stuck with the same cooling system concept as before – by drawing hot air from the keyboard and out from the chassis. Exceptional cooling system as always.



At the end of the day, the G752 remains one of the best gaming notebooks on the market but there are several key aspects that should be considered when compared to its direct competitors – Dell Alienware 17 and Acer Predator 17. It’s also more advanced than its G751 predecessor in terms of hardware but falls short when it comes to overall build and mobility. The teardown revealed roughly the same concept as before but with a different choice of materials that leads to less rigidity and solid feel. Some parts can be replaced with aluminum elements to elevate the feel and others need to be more solid, like the lid and keyboard tray for example. Also, the designers still incorporate most of the ports on the right side of the chassis making it a bit overcrowded. However, we are still happy with the input devices as both, the keyboard and touchpad, offer superb usability and user experience.

Anyway, the notebook offers hardware that’s on par with the competition and it’s even a more practical solution compared to the Acer Predator, which has two different M.2 PCIe standards – one 2280 and one 22110 with different connectors. The G752 uses two 2280 M.2 PCIe NVMe SSD slots and yet doesn’t support RAID 0 configurations. On the contrary, the Predator and Alienware support RAID 0 storage setups. So if the latter is important for you, we suggest looking somewhere else.

The cooling system once again proved to be effective and relatively silent and we suspect that the final unit, since we are using an engineering sample, will do even better. Either way, we didn’t observe any throttling or excessive heat thanks to the design of the cooling system, which draws hot air from the keyboard area. Nonetheless, the battery life is a big letdown compared to the last generation. The G751 had much bigger battery (8-cell 88Wh compared to the 6-cell 66Wh) and also the absence of iGPU (switchable graphics) in the G752 led to significant decrease in battery performance.

Finally, we would like to address the screen as this is probably one of the most important aspects in a gaming laptop. The G752 inherits roughly the same panel as before, but that’s not necessarily a bad thing. The screen features high maximum brightness, excellent contrast ratio, high sRGB color gamut coverage, 75 Hz refresh rate, good viewing angles and a G-Sync chip for smooth gameplay. The latter isn’t present in the Acer Predator so this might be a deal-breaker for some.
