Benchmarks gaming: Aorus GTX 1070 Gaming Box versus gaming laptop
Time for some benchmarks. As mentioned in the introduction of this article, we will first compare the combination of an Aorus GTX 1070 Gaming Box plus a light ultrabook with a gaming laptop that has a GTX 1070. To show the differences between laptops with two and four lanes, we conducted the tests on two different laptops.
The two ultrabooks both come from Dell's well known XPS 13 series. From the new model, with suffix '9370', we know that it is equipped with a Thunderbolt 3 connector which is internally connected via four lanes. The predecessor, the XPS 13 (9360), has a connection with two lanes. This way we can compare a laptop with 4 pcie-lanes and one with 2 lanes available for the Thunderbolt connection.
Both the new and old XPS 13 feature an Intel Core i7-8550U processor. By using hyperthreading the recent Kaby Lake R-quadcore can work on eight tasks simultaneously, at a maximum clockspeed of 4 GHz. There is 8 GB of memory available on both machines. If you order the new XPS 13 (9370) from Dell in this configuration, it costs about 1631 dollars; this price does of course not include the Gaming Box.
The two XPS laptops will take on the Aorus GTX 1070 Gaming Box against the HP Omen 17-an051nd, a gaming laptop that you can now buy for about 2000 euros. The 17.3 inch laptop has all the looks you would expect from such a system: red accents, aggressive lines and large rear air outlets. The weight, more than three and a half kilos, is more than that of the XPS 13 and the Aorus GTX 1070 Gaming Box combined. In addition to the GTX 1070, the Omen 17-an051nd has an Intel Core i7-7700HQ quadcore as well as 16GB of memory. Unfortunately, we did not have any gaming laptops available to us that, like the XPS 13, are equipped with 8GB ram.
In the graphs below, the HPmen 17 can be recognized by a red bar. The XPS 13 9370 has a yellow colour, the older XPS 13 9360 has a blue bar. With the XPS 13 laptops, we conducted the test using an external monitor connected to the Aorus Gaming Box as well as using the internal screen of the laptop. Because the XPS 13 has a Full HD display, both laptops lack results in the 4K benchmarks on the internal screen.
Far Cry Primal
In the first game in our benchmark series, the difference between the XPS 13 and the gaming oriented Omen turns out to be quite big, especially when we focus on 1080p. The big difference in performance between normal and high settings in the two XPS variants is also striking. Here, they score about 20 fps less, while the score of the Omen is barely any lower. The same can be seen in 4K: two XPS notebooks come close when using low settings, but the difference increases with a higher quality setting. This is presumably due to the bottleneck of the Thunderbolt interface.
GTA V is a game that relies more on the cpu. This is why there is a smaller difference between the Omen 17 and the XPS 13, even if we increase the settings to 'High'. It is worth mentioning that the difference between the new and the older XPS 13 is bigger compared to the first test. This could be due to something other than the 9360's slower Thunderbolt interface. One of the improvements to the new model is improved cooling for the cpu, with two fans instead of one. The older notebook might be at a thermal limit here.
Metro Last Light
In Metro Last Light, a graphically intensive game that mainly relies on the gpu, we see about the same results as the ones we saw in Far Cry Primal. On average over the four different measurements, the XPS 13 (9370) connected to the Gaming Box achieves about 81 percent of the average fps of the HP Omen 17, when you play on an external screen. The loss of performance when using the internal panel is particularly significant in combination with the XPS 13 9360. In this case the average frame rate is about 43 percent lower in 1080p with 'Very High' settings than it is with the Omen 17.
