Laptop GTX 980 Reviewed: GT72 Dominator Pro G Benchmarks

Additional Info

The GT72 Dominator Pro G is MSI's latest gaming notebook, primarily symbolic for its inclusion of nVidia's GTX 980 desktop GPU. Last month, we reported that desktop GTX 980 GM204 chips were en route to the notebook market, already integrated in various form factors and manufacturer offerings. We've gotten hands-on with a few GTX 980 notebooks – the Aorus X7 DT, CLEVO P870DM, ASUS GX700VO, MSI GT72 – and have seen form factors spanning slim (<1” thickness) through the usual “desktop replacement” models (2”, for the GT72).

Our first GTX 980 notebook review is of MSI's GT72 Dominator Pro G, including gaming (FPS) benchmarks, thermal & temperature plots, battery life, and value. There's no softening the blow with this one: It's $3100, 2” thick, and weighs about 8.4 lbs. This is, in its truest form, a “desktop replacement” laptop. Of note, we previously reviewed CyberPower's Fangbook III with a GTX 980M, which is a rebranded MSI GT72 notebook using the mobile version of the GTX 980 – a slimmed-down offering from today's model. With the Fangbook on extended loan, we were able to re-benchmark performance and conduct a GTX 980 vs. GTX 980M laptop benchmark. To expand on this just slightly, a desktop GTX 980 was also benchmarked as a parity-check with the more thermally-constrained notebooks.

The GTX 980 and its GM204 GPU appear in unmodified fashion in the GT72 notebook; this isn't a “mobile” GPU or “980M,” it's a desktop GTX 980. The GTX 980 for notebooks, as found in our review unit, is equipped with all 2048 CUDA cores, 64 ROPs, 128 TMUs, and a similar memory spec (4GB or 8GB GDDR5, OEM-dependent) to the desktop GTX 980 we reviewed last year.

The main “loss” against the desktop GTX 980 is clock speed. There's a slight down-clock of the GT72's GTX 980, which ships at ~1064MHz base. The GTX 980 reference card – something no one buys at this point – sits at 1126MHz, and that number only climbs as we factor-in same-cost AIB alternatives. The clock-rate reduction is in favor of thermals, already bordering against the desktop GPU's heat generation. We'll look at that later.

Compared to the GTX 980M, the GTX 980 has a significantly faster (+40%) memory clock, at 7Gbps vs. 5Gbps effective speed, 512 more CUDA Cores (2048 vs. 1536), and more overclocking headroom. It's also going to be a bit warmer, with all that packed into the same notebook enclosures, but nVidia has amped-up its vendor hardware recommendations to accompany the 980's needs.

One such shift is toward more powerful VRMs, with all GTX 980-equipped notebooks utilizing between 4- and 8-phase GPU VRMs. For perspective, most notebook GPUs host 3-phase power designs, which is fine for anything that doesn't make overclocking a focus – but the 980 thrives on more.

Another nVidia-to-OEM recommendation is that vendors include unlocked CPUs in their laptops, ensuring (1) a better overall fit for the GPU OC enthusiasts and (2) reduced possibility of GPU bottlenecking.

At $3100, the GT72 Dominator Pro G isn't cheap. That's about the cost of two 980-equipped desktops, but the price becomes more clear as we factor-in G-Sync inclusion, the 75Hz, high-quality display, and the i7 + 980 high-end silicon. These features – and the price – make the GT72 Dominator Pro G an option for video editors on the go and desperate gamers who travel. For comparison, the existing GT72 980M notebooks can be had around $2100 (without some features), for anyone who wants to look at what $1000 less gets you.

MSI GT72 Dominator Pro G Chassis, Thermal Design, & Maintenance


Thermal design is arguably more important for notebooks than for single video cards. A fault in a notebook will compromise the entire system, with entropy building as close-proximity components irradiate one another with heat.

As we stated with the old GT72 – the GTX 980M model – MSI's GT72 Dominator Pro G is incredibly easy to access, with nearly all the core components immediately presented under the back panel. Anyone who's ever opened a notebook knows how rare this is. Rather than burying the CPU and GPU under multiple layers of screws (and the keyboard), the GT72 bares all under a single panel. A few screws gone and we'd be ready to replace the thermalpaste, if ever necessary, and that's a huge positive for any high-end notebook with a long lifespan.


The thermal design is pretty simple with the GT72: The CPU and GPU each have separate aluminum coldplates that run to fans in opposing corners. The coldplates are bridged to fans with three copper heatpipes (coated with black paint). These run to a finned aluminum heatsink in the rear of the notebook, similar to what's found in VRM coolers for GPUs. The fans dissipate heat from the fins and send it out the back. A single, copper heatpipe bridges the CPU and GPU coldplates to another, separate coldplate, utilizing more of the real estate available for efficient cooling.

The key takeaway here is the ease-of-access granted by the GT72, making for the most effortlessly maintained notebook I've ever worked with.

MSI GT72 Dominator Pro G Display & Audio


The GT72 Dominator Pro G's audio output is nothing short of superb. I've had a mixed experience with laptops – some have speakers which are uselessly quiet, some are crackly from interference / impedance, and nearly all non-enthusiast laptops lack bass. The nature of this final issue, of course, is the acoustic limitations imposed by a smaller body. There's nowhere for the sound to generate rolling booms in a slim form factor.

The GT72's large chassis makes it a natural chamber for resonating booms, amplified by a sub-woofer on the underside of the unit. The rest of the output is channeled through the four top-mounted speakers. We don't do dBA testing at this site in an official capacity, but it's loud – there's no question that the speakers are sufficiently loud for users not utilizing some plug-in system.

MSI's display runs a 75Hz refresh rate, faster than most, and is G-Sync equipped. G-Sync, as ever, offers fluid framerates by slaving the display to the GPU, rather than the other way around. Learn more about that here.


We've encountered one somewhat major issue with our GT72 unit, but suspect (and have been informed that it is likely) that this is shipping damage. The display enclosure peels away at the hinge (bottom left) when opening and closing the lid. It's popped back together easily enough, but would crack the plastic housing after enough repetitions. MSI assures us that they have never witnessed this in-house. It is our thought that this is either shipping damage or a rare occurrence of a factory defect.

Steve started GamersNexus back when it was just a cool name, and now it's grown into an expansive website with an overwhelming amount of features. He recalls his first difficult decision with GN's direction: "I didn't know whether or not I wanted 'Gamers' to have a possessive apostrophe -- I mean, grammatically it should, but I didn't like it in the name. It was ugly. I also had people who were typing apostrophes into the address bar - sigh. It made sense to just leave it as 'Gamers.'"

First world problems, Steve. First world problems.
