Our testing methods
To put Gigabyte's Aorus X5 v7 to the test, we submitted it to a variety of synthetic benchmarks and analyzed its performance in a variety of gaming titles. It's not exactly a race if there's only one car on the track, though, so we rolled out another contender: Gigabyte's Aero 15 gaming notebook. That notebook will be getting its own full review soon, but in the meantime its performance numbers will help provide some perspective for the X5 v7.
It's worth noting right off the bat, though, that this is not a fair competition. The Aorus X5 has a Core i7-7820HK inside, while the Aero 15 is powered by the lesser, but still powerful Core i7-7700HQ. Whereas the Aorus X5 sports a GeForce GTX 1070, the Aero 15 makes do with a GTX 1060. The Aero 15 also has a thinner chassis with less room for ventilation, potentially limiting how well it can perform when its components heat up. Finally, the Aero 15's display has a maximum resolution of 1920x1080, so the Aorus X5's performance numbers at 2880x1620 will have to stand alone for the moment.
From one-button overclocking to fan profiles, gaming laptops come with a variety of settings that users can adjust to squeeze more performance out of their hardware. For our testing, we try to stick with the out-of-the-box laptop settings wherever possible, except where those settings wouldn't be a practical choice for most users. Specifically, we use the "balanced" power profile mode (in Gigabyte's control software and in Windows), use the "gaming" fan profile, and disable any automatic overclocking provided by Gigabyte's control software. We figure that most users would prefer their notebooks to be as cool, quiet, and efficient as possible, provided that their games run well. Later on in this article, we'll explore the Aorus X5's overclocking options.
The first set of tests are part of the AIDA64 Engineer benchmarking suite. The first test is CPU PhotoWorxx, which performs a variety of common digital photo processing tasks on a very large image. The benchmark uses only basic x86 instructions while putting stress on the CPU and the memory subsystem. The second test from AIDA64 Engineer is CPU Hash, an integer benchmark which uses a hashing algorithm to measure CPU performance. FPU Julia and FPU Mandel measure 32-bit and 64-bit floating-point performance, respectively.
The Aorus X5 takes the win in every category, but there's not a lot of breathing room between the Core i7-7700HQ and the Core i7-7820HK, at least in these tests. The i7-7820HK's highest margin of victory appears in the FPU Julia test, where its score was 6.8% higher than the competition.
