MSI GT72 Dominator Pro Review: GTX 980M Reigns Supreme

Battery life is one area where the GT72 isn’t going to be the best notebook on the planet, but hopefully you knew that going into the review. Seriously: when was the last time a true gaming notebook could also last all day between charging? Anyway, the GT72 as I mentioned earlier is interesting in that MSI has decided to forego Optimus support and instead use muxes with a software switch to enable/disable the discrete GPU (with a reboot required for the change to take effect). We’ve tested with both the GTX 980M as well as the HD 4600, and of course turning off the dedicated GPU improves battery life… but perhaps not quite as much as you might at first guess.
First things first, the MSI GT72 with the GTX 980M enabled managed to last as long in our Light battery test as the MSI GS60 with Optimus support. I’m not sure it’s praise of the GT72 so much as a further indictment of the poor battery optimizations on the GS60, and frankly the GE60 and GT70 aren’t winning any awards for battery life either. What’s really important however is that MSI seems to have made more of an effort to provide decent battery life with the new GT72, and when we switch to the Intel HD 4600 we even manage to reach nearly six hours of mobility. This is all with the same capacity battery as the GT70, though I should note that at one point MSI had a BIOS update on the GTX 780M variant of the GT70 that achieved around six hours of battery life as well.
Switching over to estimations of power draw, in the Light test the GT72 uses ~14.8W (give or take) with the HD 4600 compared to ~22.1W with the GTX 980M, so having the discrete GPU active appears to result in a constant power drain of around 7W. That’s as much as some Ultrabooks use in light workloads, but that’s the price you pay for high performance (and 8GB of GDDR5 memory). The Heavy testing basically confirms those numbers: power draw with the HD 4600 active ends up being ~18.7W while turning on the GTX 980M the GT72 uses ~29.2W. (The Heavy workload involves H.264 video playback, so the GPU is going to be more active.)
We already did an in-depth look at BatteryBoost on the GT72, so I’m not going to get into it too much here. Gaming without BatteryBoost will generally mean less than an hour of battery life, while dropping to a 30FPS target will in some cases allow you to break two hours of mobility. The trick of course is that by targeting 30FPS you’re effectively turning the GTX 980M into something a lot more like a GT 750M in terms of performance, but it’s nice to have options. Also note that with the battery being behind the chassis cover on the bottom, there’s no way to swap batteries to extend your mobile time, so carrying the AC adapter with you is pretty much a requirement.

Sadly, we haven't had a high-end AMD mobile GPU in for testing since the 7970M a couple years back, which was tested on an older gaming suite. You can check results in Bench, though:http://www.anandtech.com/bench/product/1378?vs=833

Thanks for the link Jarred! I logged just in time to see you'd already done the work for me. Truly appreciated.From what I can see the 980m would offer me anywhere from a 30% to over 100% boost in gaming, which is seriously impressive. I've always been a fan of bang for buck (thus the 7970m) but I have to say I'm seriously impressed with what Nvidia have achieved this generation, particularly considering we're still on 28nm here.

good review, this part is not right:"Second, the RAM has two SO-DIMM slots in the main area under the laptop, but there are two more that are accessed after removing the keyboard and top portion of the chassis; I didn't want to hassle with that as it's not really necessary for the review"
i have the 211 sku, and you cant remove the lid and the keyboard from the top on the gt72. To get to those ram slots you have to disassemble most of the laptop through the back cover on this model. should not be a big deal- the cheapest sku they offer comes with 16gb already populated into those slots. so the only people who will deal with those slots are people who want lower cas ram or people doing repairs if the ram goes bad.

Text edited, thanks. As noted, I didn't actually disassemble the system to check the battery and other RAM slots, so all I could say for certain was that they were on the opposite side of the motherboard.DILLIGAFF - Tuesday, November 11, 2014 - link
Thanks dude!as far as that second unused 2.5" bay- there is a sku (non usa sku as of today afaik) that comes with no SSD, so instead of a bracket to hold m.2 drives, there is a bracket that has connectors for both 2.5" bays- at least one is sata 6. this is sort of relevant because in the sku's that come with the m.2 bracket/ssd, there is no sata 3 port for a 2.5" drive.

Unfortunately, these things become expensive paper weights after 2 years. They just don't hold much of their value over time. You can probably get 80% of the performance of this laptop while spending only $1,500.00 or so.JarredWalton - Tuesday, November 11, 2014 - link
Yes and no. A desktop with similar performance will cost between $1400 and $1500 (with 32GB RAM and a 512GB SSD), but that doesn't include the display, speakers, or keyboard/mouse... and what it really doesn't include is portability. No matter how much people want to try and say otherwise, there are users that want a portable gaming system like this. And in two years, while there will be faster GPUs available, that hardly makes an older system obsolete -- a three year old gaming notebook can easily handle most games today, just not at maximum settings.CrazyElf - Tuesday, November 11, 2014 - link
One advantage that this laptop has is that the GPU is upgradeable.Asus G series is not. Alienware, some models are. Many of the Clevo models are.
CPUs don't seem to improve much every year, so it's not as big a deal.

Have MxM cards actually become available at sane prices? The last time I looked the premium on them was so large it was cheaper to dump the old laptop on ebay and buy a new one.Also, is cooling still a concern with MxM swapping? IIRC something about early generation ones had problems with the heatsink connectors changing between generations making the upgrades nearly impossible in practice.

Pretty good gaming laptop all things considered. For the money, you get better hardware than what a comparable Alienware offers.The only thing I wish for is that the battery was user replaceable. Gaming laptops don't have good battery life times, and this one is decent with the integrated, but still I'd like to be able to hot-swap on the go.
The are already IPS GT72s coming in, which should fix the only real flaw of this laptop, which is the poor color accuracy of the TN display. You will no doubt have to pay extra though for the IPS display.
I believe that the GPU can also be upgraded, leaving future potential upgrades available. Unfortunately, the CPU has been soldered, which has become standard among all gaming laptops.
Otherwise a solid laptop.
