Prior to testing, we downloaded the latest GPU drivers and disabled G-Sync, as leaving it on would have hampered benchmarking results. Smooth game play is best served by leaving G-Sync turned on, but for the purpose of seeing how the G751JY-DB72 performs compared to other gaming laptops, we left it off for the duration of our benchmarks.

Futuremark PCMark 7
|
Simulated Application Performance
|
|
Futuremark’s PCMark 7 is a well-known benchmark tool that runs the system through ordinary tasks, including word processing and multimedia playback and editing. Graphics and processor power figure prominently in this benchmark, but graphics power doesn’t play as big a role here as it does in another Futuremark benchmark, 3DMark (which is designed for testing the system’s gaming capabilities). This test also weights heavily on the storage subsystem of a given device.
The ASUS G751JY-DB72 stormed its way to the front of the pack, trailing only the Eurocom P5 system, which sports a desktop-class processor. There's a pretty big disparity in CPU performance between the Core i7-4720HQ (2.6GHz to 3.6GHz, 6MB cache) and the Core i7-4790K (4GHz to 4.4GHz, 8MB cache), so we're not surprised by the results.
Compared against laptops running mobile processors, the G751JY-DB72 proved the strongest performer.

Maxon Cinebench R11.5
|
Simulated Application Performance
|
|
Based on Maxon Cinema 4D software, this test uses a 3D scene and polygon and texture manipulation to assess GPU and CPU performance. We usually opt for the Main Processor Performance (CPU) test, which builds a still scene containing about 2,000 objects, for total polygon count above 300,000. We run the test twice: once with only one processor core enabled, the next time with all CPU cores blazing. Cinebench displays its results in points.
In Cinebench's OpenGL test, the G751JY slid to around the middle of the back. Interestingly, its CPU score was the second highest, which again only trailed the desktop part.

Futuremark 3DMark Fire Strike Extreme and Sky Diver
|
3D Game Performance
|
|
Futuremark designed 3DMark Fire Strike for desktop PCs, but today’s heavy-duty gaming laptops have the chops to take on the high-resolution texture, tessellation and other components of the test. Sky Diver is Futuremark’s dedicated laptop benchmark. This is a good test for entry- and mid-range gaming laptops.
With the focus switched towards gaming performance, the ASUS G751JY-DB72 wastes no time flexing its burly configuration. Not including the optional desktop-class GTX 980 AMP that plugs into the Alienware system, the G751JY led the way in 3DMark's Fire Strike test, and sat on top during the Sky Diver run. In both benchmarks, it was able to put the Eurocom P5 Pro and its 4790K processor in the rear view mirror.
