A powerful NVIDIA GeForce RTX 2060 video card is responsible for the graphics. This is an analogue of a desktop video card on the TU106 with 1920 stream processors, a 192-bit bus and 6 GB of video memory. The difference between the mobile version is in lower frequencies, which allows it to meet the TDP of 80-90 watts. The base core frequency is 960 MHz and Boost Clock is 1200 MHz instead of 1365/1680 MHz for the desktop version. Effective memory frequency 14000 MHz. The Core i7-9750H has an integrated Intel UHD Graphics 630.

The storage system is represented by one 512 GB NVMe Intel SSDPEKNW512GB drive. If two devices are installed, RAID0 mode is supported. Networking features come standard with Gigabit Ethernet, Wi-Fi 802.11ac, and Bluetooth 5.0 (based on the Intel 9560D2W dual-band adapter). There is no memory card reader, but its relevance is questionable.

Software

Full software control of the laptop and a wide range of additional features are provided by the Armory Crate application. This is a software center that has tools for monitoring and selecting operating modes, setting the backlight and selecting additional ASUS utilities from a single menu.

The first tab of Armory Crate offers a simple and intuitive interface for controlling operating modes. It’s worth noting that ASUS software replaces the default power modes with its own profiles. By switching between them, you select the preset options for settings for a specific device with optimized parameters. By default, the laptop runs in balanced mode. There is a quiet mode with the usual combination of reduced power and high efficiency. The Turbo mode will provide maximum performance, which provides for a slight overclocking relative to the initial settings.

The main menu of Armory Crate is called up with the ROG button on the keyboard, and work profiles can be quickly switched with the F5 button.

A separate section contains glow effect settings for the keyboard backlight. There are ready-made profiles and the possibility of manual combination of settings.

ASUS ROG Zephyrus M GU502

The set of available programs includes many special gaming utilities. For example, GameFirst V allows you to control network traffic and network bandwidth for different tasks. There are also several free games included, among which Ghost of a Tale and Beholder deserve special attention.

Cooling System Efficiency and Noise Level

It’s time to talk about the temperature characteristics of the laptop. The operation of ASUS ROG Zephyrus M GU502 was carried out in a room with a temperature of about 27 ° C. During the tests, the temperature of the internal components was monitored and the temperature of the outer case was measured.

To create the maximum load, the AIDA64 stress test was used. First, we activated the full load option for all components, including the GPU.

ASUS ROG Zephyrus M GU502

Quite quickly, the processor warmed up to 90 ° C, after which the frequency reset began and a slight throttling appeared. This is normal for mobile Intel processors under extreme load. But in this case, it is worth noting the low final frequencies, when the core frequency dropped below 2 GHz. According to HFWiNFO, the average frequency is 2 GHz at operating temperatures up to 80 °C.

If you remove the load from the graphics core, then the overall dynamics of the processor will improve.

ASUS ROG Zephyrus M GU502

Peak core temperatures are around 90°C, but average heating is decreasing. And the average core frequency is already 3300 MHz. That is, without a load on the graphics, the Intel Core i7-9750H will work stably at frequencies above the base level even in extreme processor tests.

The main area of ​​​​use of this laptop are gaming applications. What are the temperature and noise characteristics of the ASUS ROG Zephyrus M GU502 under gaming load? Let’s check it out with a 20-minute continuous test of Final Fantasy XV: Windows Edition. This is a fairly heavy test that makes the most of the video memory and warms up the GPU well.

ASUS ROG Zephyrus M GU502

The frequency of the GPU is kept in the range of 1200-1300 MHz, which is noticeably lower than the average frequency level of the desktop version. GPU temperature reaches 76°C. The peak temperatures of the Intel Core i7-9750H are at the level of 96-97 °C, but these are the values ​​at the time of start at high frequencies. With a long load, the frequencies gradually decrease, the average values ​​are 3.5–3.6 GHz. At a particular point in time, we see a different multiplier for all cores, where the maximum value is x38.

High temperatures come with noticeable cooling noise, but we’ve had noisier laptops as well. Therefore, we can talk about standard temperature and noise characteristics against the background of other game models. And the problem of noise is not relevant in the case of using headphones. Operating temperatures are high, but all models with powerful Intel Cores peak and show throttling under stress. Under normal gaming load, the heating is serious, but the CPU frequencies are kept at a high enough level, which will ensure good final performance. And this is at an ambient temperature of 27 ° C, in cooler conditions the CPU frequencies can be even higher.

Let’s see what the external case temperatures are like under high load (Final Fantasy XV: Windows Edition).

ASUS ROG Zephyrus M GU502

The outer case heats up the most in the central zone above the CPU and GPU, but it feels weak tactilely, there is no discomfort in operation.

Overclocking

ASUS ROG Zephyrus M GU502 has a regular enhanced performance mode. To activate this Turbo mode, just select the appropriate profile in the Armory Crate menu or switch modes with the F5 key.

ASUS ROG Zephyrus M GU502

In this mode, the speed of the blowing fans increases, which allows you to keep the increased frequencies of the CPU and GPU. The frequencies of the video card are additionally increased above the initial level. The base value of the core is 1060 MHz with an average Boost of 1300 MHz, the memory frequency is 14300 MHz.

ASUS ROG Zephyrus M GU502

When loaded with Final Fantasy XV: Windows Edition, average GPU frequencies exceed 1400 MHz at temperatures up to 77 ° C, and processor cores operate at frequencies of 3.9-4 GHz. That is, we have really good acceleration. But since it is achieved through better cooling, the overall noise also increases, which is noticeable even with a light load.

ASUS ROG Zephyrus M GU502

We decided to squeeze even more out of the laptop. And this is indeed possible, but further growth will be minimal. With an additional increase in the frequencies of the video card, stability decreases and performance drops due to overclocking are possible. Therefore, we settled on such a frequency configuration for the GeForce RTX 2060 — 1100/1340 MHz core, 14500 MHz memory. The overclocking itself was carried out in active Turbo mode to ensure optimal cooling.

ASUS ROG Zephyrus M GU502

Under heavy load, the GPU boost frequencies remained almost unchanged, the temperature increased by one degree. The CPU operating mode also remained unchanged.

ASUS ROG Zephyrus M GU502

Next, we will test the laptop in all the described modes to evaluate the benefits of the regular mode, Turbo mode and additional overclocking.
