ASUS ROG Zephyrus G15 GA503 (2022) – Top 5 Pros and Cons

The Zephyrus G15 was one of the best notebooks of 2021, providing performance and portability. Yes, it cost an arm and a leg, but it excelled in every type of workflow you can think of. Well, it’s 2022 and it’s about time the G15 got in proper shape to compete with its competitors, sporting a CPU and a GPU upgrade.

Due to its portability being critical, we have AMD’s 35W Ryzen 6000HS series processors, with the Ryzen 7 6800HS and the Ryzen 9 6900HS. These chips are using refreshed Zen 3 cores, called Zen 3+, which are built on a smaller 6nm node, and sports performance and efficiency improvements. In terms of graphics, there are two 120W GPUs, with either the RTX 3060 or the RTX 3070 Ti.

Today we present you with LaptopMedia’s top 5 picks about the ASUS ROG Zephyrus G15 GA503 (2022).

ASUS ROG Zephyrus G15 GA503 (2022): Full Specs / In-depth Review

3 reasons to BUY the ASUS ROG Zephyrus G15 GA503 (2022)

1. Display quality

There are two QHD displays to choose from, with either a 165Hz or a 240Hz refresh rate. We tested the lesser unit, which comes with comfortable viewing angles, a max brightness of 328 nits in the middle of the screen, 325 nits as an average for the whole area, a maximum deviation of only 5%, and a contrast ratio of 1030:1. The laptop has great brightness uniformity, which unlocks its Creator capabilities, something that is further fortified by the 100% sRGB and 98% DCI-P3 coverage.

Our Design and Gaming profile was hardly able to do anything about the accuracy, but the laptop can reach good dE levels by itself, by changing to a D65 white point and using the DCI-P3 gamut. Here are the results with the stock settings (left) and with the white point adjustment (right).

In addition to receiving efficient and health-friendly profiles, by buying LaptopMedia's products you also support the development of our labs, where we test devices in order to produce the most objective reviews possible.

Office Work

Office Work should be used mostly by users who spend most of the time looking at pieces of text, tables or just surfing. This profile aims to deliver better distinctness and clarity by keeping a flat gamma curve (2.20), native color temperature and perceptually accurate colors.

Design and Gaming

This profile is aimed at designers who work with colors professionally, and for games and movies as well. Design and Gaming takes display panels to their limits, making them as accurate as possible in the sRGB IEC61966-2-1 standard for Web and HDTV, at white point D65.


Health-Guard eliminates the harmful Pulse-Width Modulation (PWM) and reduces the negative Blue Light which affects our eyes and body. Since it’s custom tailored for every panel, it manages to keep the colors perceptually accurate. Health-Guard simulates paper so the pressure on the eyes is greatly reduced.

2. Upgradeability

The upgradeability struggles a bit, but both types of memory slots are found here, so we’ll give it a pass. Half of the RAM is soldered, but the rest is upgradeable through a single SODIMM slot, which fits DDR5 RAM. In terms of storage, there are two M.2 PCIe x4 slots, which fit Gen 4 drives.

Here is our teardown video, which goes in-depth about taking apart the G15 and accessing the slots on the inside.

3. I/O

While there is an obvious lack of Thunderbolt support, the I/O still covers a lot of ground, with two USB Type-A 3.2 (Gen. 2) ports, two USB Type-C 3.2 (Gen. 2) ports, an HDMI 2.0b port, a MicroSD slot, an Ethernet port, and a 3.5 mm audio jack.

2 reasons NOT to buy the ASUS ROG Zephyrus G15 GA503 (2022)

1. Input devices

The G15 has made some sacrifices, mainly scrapping the NumPad, but ASUS could have done something to remedy that. The keyboard has very good key travel and clicky feedback, while the touchpad offers a smooth gliding surface. The problems for us come with the small Arrow keys. The touchpad also could have included the NumPad, as we have seen ASUS do that with previous laptops and the tech seems to be already well developed. It’s not like this is an affordable laptop, so ASUS might as well go all in.

2. Battery life

There is a huge 90Wh battery, but despite its best efforts, the laptop is completely outshined when t comes to battery life by its predecessor, while featuring similarly if not better-performing hardware. The 2022 model lasts for 7 hours and 58 minutes of Web browsing, or 6 hours and 25 minutes of video playback. Here are the compared results from our battery life test of the 2022 model versus the 2021 model.

In order to simulate real-life conditions, we used our own script for automatic web browsing through over 70 websites.

For every test like this, we use the same video in HD.
