 Two GTX 1080 graphics cards in a single laptop? Who would be crazy enough to do that? Asus, Sager, Acer, and MSI. That's right my friends. The laptops in our gaming roundup today are not for the faint of heart or the faint of wallet. Between them they have a total of eight GTX 1080s in them and they cost over $20,000 The white dark base pro 900 from be quiet features a modular design to support a variety of layouts and configurations check it out at the link below Let's meet the contestants starting with the NP 9873 from Sager the OG of mobile SLI It's rocking a core i7 6700k CPU making it the only machine with a sixth generation core processor, but It's also the only one using a desktop CPU. So that might end up being an advantage Next is the MSI GT 83 Titan SLI whose Cherry MX mechanical keyboard and 18.4 inch display make it suitable for use as a weapon Moving on we've got the Asus GX 800 whose highlights include a 4k G sync display and oh yes, an outboard water cooling unit which might give it an edge when we overclock these suckers later and finally coming in at a whopping $9,000 the most bonkerdoodles laptop that we have ever laid our hands on with a curved ultra-wide 120 Hertz G sync display a Full mechanical keyboard and an included pelican case for transport the Acer Predator 21x the test environment for the showdown was our conference room held at 21 degrees and For all of the tests we set all factory over clocking modes and fan speeds to max loud Yes Unpleasantly loud also, yes But the goal of this video to use a car analogy is to watch them drag race Not to discuss the resolution of their backup cameras So for our first test we wanted to see which of these beasts could sustain the highest CPU clock speed Under a full load so we ran an IDA 64 stress test for 15 minutes Then took the average temperature clock speed and power draw in watts for the next five After an ear-shattering quarter of an hour a winner emerged And if you guessed that the laptop with water cooling had the best cooling results you would be Totally incorrect actually believe it or not the laptop that best tamed its quad core CPU was the Sager NP-9873 coming in at just under 4 gigahertz average Now you might remember from our review that the gx800 was able to operate at 4.1 gigahertz But remember we were using their overclocking software to overclock and that required some undervolting Asus's factory overclock is a little bit too generous with the voltage Perhaps even more surprising than the clock speed winner is the fact that in spite of their size None of these devices ran at a comfortable temperature at these clock speeds with the predator 21x being the most Frequent throttler with occasional trips down to 800 megahertz Time for a Cinebench speed run where thanks to the quick duration of the test the gx800 pulled out a convincing victory with a score of 946 just ahead of the predator 21x single-threaded results were a similar story But of course if you've got this much money to spend on a gaming laptop You've probably got a separate workstation for all of that kind of stuff So let's get to the gaming results all tests were done at 1080p Ultra details and with FXAA enabled for an apples to apples comparison in In rise of the tomb raider direct x12 the gx800 pulled off a clear win and the predator 21x showed the value of tweaking factory settings by disabling Acer's predator software and Slowing our overclock down to turbo we actually managed to solve some fairly unpleasant stuttering issues So we'll use these settings for the rest of our tests in direct x11 We see a different story the seger np 98 73 stomped all over the other laptops Putting up similar numbers to direct x12 while the rest took a big hit The story remained the same in Deus ex as well with the water-cooled gx800 proving that once again It's the king of direct x12 and with the seger taking the crown in direct x11 There must be something about direct x11 that favors its desktop CPU while the mobile chips are being more effectively used in the newer API a Hypothesis that was strengthened when the CS go scores favored the seger once again Our last gaming test is for honor where the overall trend of the video continues to Not be a thing weird So the predator 21x takes home its first victory here leading us to conclude then that if you're shopping for the fastest Bestest laptop out there there isn't going to be a clear winner in every possible Category on to battery life then it was Well, what did you guys really expect it was a poop show they're gaming laptops not thin and lights Leading us then to conclusion time the only laptop that didn't bring home a single metal was the MSI GT 83 Titan, but it was also the most consistent performer across the board Thanks to its lower clock speeds and less frequent thermal throttling Maybe MSI's engineers figured the extra performance wouldn't matter anyway because of its 1080p 60 Hertz display So as usual it's not as simple as which one is the fastest the gx800 might look like an obvious choice But if you want to use the external dock to get an estimated 10% performance boost it Literally requires you to carry around a luggage to keep it in and the Sager might look compelling on paper But it is probably the most obnoxious sounding of all of them while gaming For all of these laptops the factors I just listed and so many more Ultimately impact the gaming experience so the beauty of any one of them is really in the eye of the beholder Meaning that the only way for us to declare a clear winner here is to ignore Subjective factors and focus entirely on objective ones bringing us to our final recommendation a gaming desktop and a more portable laptop and you could probably throw in an EGPU for your portable laptop while you're at it Squarespace makes it easy to
