Xiaomi mi fresh edition đánh giá

Budget gamer. Back in 2019 the Xiaomi Mi Gaming Laptop not only surprised us with a sturdy high-quality case but also a good price-performance ratio. Find out whether the 2019 iteration follows suit.

As previously reported three different models of the 2019 edition of Xiaomi’s Mi Gaming Laptop will be available. A base model equipped with a Core i5-9300H with 8 GB of RAM, a mid-range model based on the Core i7-9750H with 16 GB of RAM, and last but not least a flagship model equipped with a GeForce RTX 2060 instead of a GeForce GTX 1660 Ti. The latter might not be that much slower than the former, but it lacks its raytracing capabilities. All units are equipped with a 144 Hz IPS FHD and a 512 GB NVMe SSD.

As with its predecessor Xiaomi’s exclusive target audience for the Mi Gaming Laptop are Asian markets, which is why it's almost impossible to tell you how much exactly the device is going to cost. By default, it ships with a Chinese version of Windows. However, some retailers offer an English Windows 10 at a premium.

Since Xiaomi has left the case mostly unmodified, except for the unfortunate omission of a previously available USB-C port, we are not going to cover case, connectivity, and input devices in great depth as part of this review. Instead, we would like to refer you to our review of the 2018 model.

* ... smaller is better

Our measurements indicate significantly reduced response times that decreased from around 41.6-53.2 ms to just 8.8-12 ms. This should make for an image free of ghosting and artifacts even when playing fast-paced shooters. Unfortunately, Xiaomi has opted not to include support for G-Sync, most likely a cost-cutting measure (re: license costs). Instead, the Mi Gaming Laptop supports Optimus in order to maximize battery life.

The IPS panel offers much more than just great response times. Thanks to a comparatively low black level of just 0.23 nits and a decent maximum brightness of 295 nits the resulting contrast ratio is 1,300:1.

Color space coverage (92% sRGB, 60% AdobeRGB) is on a par with the competition, and so are the viewing angles.

Display Response Times

ℹ

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.

In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 25 % of all devices are better. This means that the measured response time is better than the average of all tested devices (21.8 ms). ↔ Response Time 50% Grey to 80% Grey8.8 ms ... rise ↗ and fall ↘ combined↗ 4.4 ms rise

This means that the measured response time is better than the average of all tested devices (34.3 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.

Screen flickering / PWM not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 18627 (minimum: 5 - maximum: 3846000) Hz was measured.

The flagship SKU can definitely be considered a high-end gaming notebook. A hexa-core CPU combined with a GeForce RTX 2060, a 512 GB SSD, and 16 GB of RAM should offer more than enough gaming and processing oomph for many years to come.

Intel’s Core i7-9750H is one of the most successful mobile processors. The 14 nm Coffee Lake -based processor with a TDP of 45 W supports Hyper Threading and thus up to 12 threads simultaneously.

It runs at a base clock speed of 2.6 GHz and can turbo boost up to 4.5 GHz. Unfortunately, the Mi Gaming Laptop is incapable of fully utilizing the CPU’s turbo boost potential. In single-threaded load the CPU runs at 4.0 to 4.3 GHz while multi-core turbo boost is limited to just 3.3 to 3.8 GHz.

NVMe SSD is a staple of pretty much every 2019 high end notebook, and Xiaomi opted for a 512 GB NVMe SSD by Toshiba. Sequential read and write speeds top out at a superb 3,000 MB/s in Crystal Disk Mark, and the M.2 SSD was also very fast in random access scenarios. Given that the Mi Gaming Laptop features a free secondary M.2 slot as well as a free 2.5-inch slot the upgrade options are plentiful.

The Mi Gaming Laptop performed very well in our GPU benchmarks. It scored first place within our test group in 3DMark 11 and 3DMark 13, which attests to a good turbo-boost utilization.

We were able to verify the latter during our 60-minute long "The Witcher 3" loop (1920x1080, Ultra), and the resulting core frequency of 1,500 MHz is much higher than the GPU’s base frequency of just 1,110 MHz. We did not notice any sudden drops in performance.

As long as you restrict yourself to gaming in FHD the GeForce RTX 2060 is more than capable of running all current games smoothly in maximum details. Only extremely taxing games, such as Anno1800 or Odyssey, might drop to less than 60 FPS on average.

In most cases you should also be fine with running games in 2560x1440. However, 4K gaming in 3820x2160 is most likely going to be too demanding for this RTX 2060.

System noise is by far the Mi Gaming Laptop’s biggest shortcoming. Just like its predecessor the 2019 model turned out to be extremely loud under load. An average of 59 dB(A) while running "The Witcher 3" is beyond annoying and practically forces users to wear headphones. At an average of 44 to 51 dB(A) its competitors were significantly quieter.

We would also like to see some further optimizations in low load scenarios, such as office tasks, video, and browsing the web. The fans remain unobtrusive at 31-32 dB(A) most of the time, but tend to randomly ramp up to 40 dB(A). This is most likely going to be a major nuisance for many users.

Considering its noise emissions, the laptops surface temperatures were neither here nor there. A maximum of 51 °C (~124 °F) at the top and 57 °C (~135 °F) at the bottom place the device somewhere in the middle of the pack. At just 23 to 27 °C (~73 to 81 °F) idle temperatures were lower than on average.

The fast spinning fans had a positive impact on internal temperatures as well. For example, the GeForce RTX 2060 maxed out at just 70 °C (~158 °F) under load and Intel’s Core i7-9750H peaked at a slightly higher yet still more than acceptable 80 °C (~176 °F) in our stress test running Prime95 and FurMark simultaneously. We should note that running our stress test resulted in a temporarily disabled CPU turbo boost.

Thanks to graphics switching on demand, the 15-inch notebook only consumed around 10 to 20 W when idle, around 100 W in 3D (3DMark 06), and 196 W under maximum load. Using "The Witcher 3" to represent typical gaming load we were able to determine an average gaming power consumption of around 160 W. The power supply is rated at 180 W.

Despite support for Nvidia Optimus the Mi Gaming Laptop is not going to break any records due to its comparatively small 55 Wh battery. As expected, it reached around 4.5 hours in our Wi-Fi test (medium brightness) and 6 hours in our idle test (minimum brightness), which is neither particularly good nor particularly bad for a high-end device. Compare this to the Asus Strix GL531GV that ran out of power much sooner at one end of the spectrum, and the Acer ConceptD 7 that ran for almost twice as long at the other. All battery tests considered the Mi Gaming Laptop was roughly on a par with the MSI GL65 9SEK and the Lenovo Legion Y540-15IRH.

Xiaomi Mi Gaming Laptop 2019

The pros and cons of Xiaomi’s 2019 edition of the Mi Gaming Laptop are pretty much identical to its predecessor’s.

On the plus side, we have a surprisingly robust high-quality case with its simple design that will fit in pretty much everywhere. We also liked its input devices as they were well-suited for both, office and gaming. The lack of Thunderbolt 3 is compensated by a fast 144 Hz display and a faster card reader.

Its biggest drawbacks are noise emissions, particularly in 3D. Simply put the 15-inch laptop is significantly too loud, something not even the great price-performance ratio can compensate.

Editor of the original article: Florian Glaser - Managing Editor Gaming Laptops - 598 articles published on Notebookcheck since 2009

I discovered my interest in computers in my childhood, growing up with MS-DOS and Windows 3.1 in the early 1990s. I was especially fascinated with computer games, even from an early age. From Monkey Island through Lands of Lore to Doom, I tried every game I could get my hands on. I have been working for Notebookcheck since 2009 with my focus mostly being on high-performance gaming laptops.

Born in the United States and raised in Germany I became acquainted with both languages from an early age and turned this into my profession later in life. Computers have always played an important role in my life, and my love for all things digital is a huge part of my daily routine. Virtual Reality has captured my imagination and interest in particular, and I cannot wait to see what the (near) future will bring.
