Re: MSI GT72S Dominator Pro GTX980 and the extreme performance of OC
#3
The headphones output is equipped with ESS SABRE HiFi DAC, which will give a more in-depth sound.
The feeling perceived by an ear is similar to the one by professional headphones SENNHEISER HD6 MIX.
Compared the difference of 24Bits-192KHz audio quality by trying more on ASUS ROG G751.
When using Realtek sound solution G751 model, High and low frequencies are less satisfying in sound performing.
When using Alienware 17 with Creative Sound Core 3D, low and high frequencies are at very good level, especially greater in midrange sound details.
MSI GT72S is equipped ESS SABRE HiFi DAC to export the headset sound, the performance is great at both high and low frequencies, also good at midrange frequency.
The grading for the sound quality: Alienware 17 – 92 points; GT72S: 90 points. But where is the last one?
MSI GT72S Dominator Pro speakers are still in collaboration with the Danish brand Dynaudio.
Below is the description of the listening experience.
This part is quite subjective, Notebook built-in speakers are taken as a benchmark.
When adjusting to the maximum volume, the Maxima volume is very loud, which makes you not to worry about a problem of quite speakers.
At the high frequency, the sound isn’t sharp. Going deep into details, the performance is above average.
At the middle frequency, the sound is quite clear, vocals sound solid though there is a room for improvement.
At the low frequency, it wins among the three frequency range, with a shocking good bass, with blooming sound experience.
If you want to watch a video or play a game, GT72S in overall proves to have a higher level sound quality.
When listening to the music, even though the middle frequency isn’t top-class, there are only a few which are excellent in this area.
As a high-performance gaming notebook, GT72S is also quite competent in terms of sound.
Comparing to Alienware 17, GT72S high and low frequencies sound great, only middle frequency still could make improvement.
GT72S storage design is its major feature.
It includes the newest Super RAID 4 technology.
You can install PCI-E Gen 3.0 SSDx2 and M.2 SATA3 SSDx2 at same time,
This model comes with NVMe PCI-E interface of 256GB SSDx2 at Raid 0 SSD.
Installed TOSHIBA THNSN5256GPU7 using 16nm MLC IC

4K - 64Thrd Read - 1181.42 MB/s Write - 876.30 MB/s
ATTO DISK Benchmark, when exceeding128k, achieves maximum Read speed of 3221Mb/s and maximum Write speed of 1926 MB/s
CrystalDiskMark
Seq Read - 3208 MB/s Write - 1949 MB/s
The performance of NVMe M.2 SSD is quite excellent, it only requires 2 M.2 slots of Raid 0 is faster than the one applied on GT80 half a year earlier of 4 MSATA slots.
In addition to the design, more bandwidth is provided with PCI-E Gen 3.0. The new NVMe protocol of M.2 SSD sharply increased the access speed.
In order to achieve above-high bandwidth transmission,
4K efficiency has also improved significantly with the greater performance.
And one more HGST HTS721010A9E630 1TB 2.5-inch HDD for data storage.
System benchmark test
PCMARK8 - 5503
PCMARK8 score also very high in the entire system performance.
The bottom picture shows GT72S already exceeding of 99% of the overall PC performance.
CrystalMark 2004R3 => 435959
Fritz Chess Benchmark => 29.92/14360
CrystalMark 2004R3 score was also high. Even though Skylake and Haswell have a little design difference, below are Fritz Chess Benchmark test results.
Since 6820HK has an overclocking ability and set to 3.7GHz, the CPU multitask effectiveness also obviously enhanced a lot.
CPU Benchmark test (Sport mode setting: CPU by 37x)
FRYRENDER
Running Time => 4m 27s
x264 FHD Benchmark => 27.2
CINEBENCH R15
CPU => 798 cb
CPU(Single Core) => 158 cb
If comparing Intel Core i7-6820HK’s preset clock to the previous generation, 4980HQ, it only has a small enhancement.
But when turning on GT72S overclocking mode, the performance increased about 32.78%, which is outstanding.
Using Sport mode for overclocking, could enable Cooler Boost 3 with push a button on left side, which will let the fan operate at its full throttle.
To boost on the 6820HK and GTX 980, it will be a great help with performance and temperature.
However the fan noise will also be increased.
Recommend to use Cooler Boost mode when ultra-loading usage, normally use the standard mode with silence.
The 6820HK at this GT72S is powerful running at 40x, overclocking CPU reach 4GHz, and it’s also completed all the critical tests.
Fritz Chess Benchmark => 32.57/15635
x264 FHD Benchmark => 29.4
Overclocking up to 4GHz in comparison to 3.7GHz
Fritz Chess Benchmark increases by about 8.9%; x264 FHD Benchmark increases by about 8%
Of course if setting only 3.2GHz with 6820HK, the 4.0GHz performance will increase by about 14%

Using DDR4 memory is also Skylake’s highlight on new PCs, lower voltage and higher frequency are improvement.
Moreover, bandwidth is also become higher. Of course, there will be single 16GB DRAM with better capabilities soon.
