Razer Blade Stealth (i7-8565U, GeForce MX150) Laptop Review

An Ultrabook for gamers. The new Blade Stealth proves that not all GeForce MX150 GPUs are created equal. It's the fastest 13.3-inch Ultrabook we've tested with graphics performance just shy of a GTX 960M all in a sleek package the size of a MacBook Pro 13.

The Blade Stealth series is Razer's version of the common Ultrabook. Whereas the Blade 14, Blade 15, and Blade Pro series are first and foremost ultra-thin gaming laptops, the Blade Stealth utilizes ULV CPUs to compete directly against brandname flagship Ultrabooks including the Dell XPS 13, HP Spectre 13, Huawei MateBook X Pro, Asus Zenbook UX433, Lenovo Yoga C930, Samsung Series 9 NP900X3N, and the MacBook Pro 13 by extension.

What makes this latest Blade Stealth so different from the competition isn't the narrow-bezel design as all the aforementioned Windows alternatives also incorporate narrow bezels in some way. Instead, it's the discrete full-power GeForce MX150 GPU that gives the Razer Ultrabook a notable graphical edge. Users who want the form factor of a sleek Ultrabook but with the graphics prowess to play the latest eSports titles should find the new Razer more appealing.

Current configurations include the Whiskey Lake-U Core i7-8565U CPU with 8 GB of RAM, integrated UHD 620 graphics, 256 GB M.2 SATA SSD, and 1080p display for $1400 USD up to the Core i7-8565U with 16 GB of RAM, GeForce MX150 graphics, 512 GB M.2 NVMe SSD, and 4K UHD touchscreen for $1900 USD. Our test model today is the middle option with the Core i7 CPU, MX150 GPU, and 1080p panel.

(February 11, 2019 update: Razer has new BIOS and EC software updates for users experiencing charging issues and/or electronic noise. We recommend contacting Razer support services for the download link.)

Case

The Blade Stealth with Whiskey Lake-U is a complete design overhaul from the previous Kaby Lake SKUs. As detailed in our preview of the new laptop, Razer has essentially downscaled its 15.6-inch Blade 15 chassis to fit a 13.3-inch screen size. The texture, material, and look of the system are consequently nearly the same as the Blade 15 including the move to a colorless logo.

Rigidity is excellent with no creaking around the base or lid. We're impressed by how stiff the thin base can be when compared to something like an Asus Zenbook UX3430. Applying pressure on the center of the keyboard flexes it just slightly. The lid is a bit more flexible than the lids of the XPS 13 or Zenbook UX433, but it's nowhere near as bad as the lids of the Samsung Notebook 9 NP900 or LG Gram 13. The long bar hinge is sufficiently firm to prevent teetering whilst typing or transporting.

Construction quality appears to be flawless from top to bottom with no unintended gaps or visual defects on our test unit. it may not be perfect, however, as we experienced a charging issue as detailed in our Battery Life section below. The system is a visual delight nonetheless as we've come to expect from a Razer product. The inevitable fingerprint buildup on the smooth anodized matte surfaces is generally easy to wipe down with the included cleaning cloth.

Razer laptops tend to appeal more to Mac lovers than the typical Windows laptop and a quick look at its dimensions shows why. The new Blade Stealth is almost identical to the MacBook Pro 13 in terms of volume and weight for similar first impressions. The new narrow bezels help the system shave off nearly 16 mm in length for a smaller footprint when compared to the last generation Blade Stealth design. Thickness has actually increased by 1 mm likely because of the new dedicated GPU.

Connectivity

Ports are identical to the last generation Blade Stealth except that HDMI has been dropped in favor of a USB Type-C Gen. 2 port. Owners may have to invest in an adapter or another cable for outputting to an external monitor.

Both USB Type-C ports are capable of charging the system, but only the right port is compatible with Thunderbolt 3 docking stations including the Razer Core.

As far as missing ports go, we're a bit bummed to see no integrated SD card reader, Kensington Lock, or HDMI. Competing Ultrabooks like the HP Spectre x360 13 have the advantage in this regard.

Communication

WLAN and Bluetooth 5 are provided by an Intel 9560 for transfer rates of up to 1.73 Gbps. Our test server is limited by a 1 Gbps line so performance can be faster than what we've recorded below. Unlike the Killer 1550, the Intel 9560 does not include special network prioritization software or features for hardcore gamers. We otherwise experienced no wireless issues during our time with the test unit.

Accessories

Extras include a few Razer logo stickers and a small cleaning cloth in addition to the usual Quick Start guide and warranty card. A USB Type-C to HDMI or Ethernet adapter would have been appreciated.

The Razer Core eGPU is once again compatible. We expect performance to be better than the last generation Blade Stealth with Core i7-8550U since the i7-8565U in the new Blade Stealth does not throttle as heavily.

Maintenance

The bottom panel requires a T5 Torx wrench similar to other Blade laptops. Access is straightforward even though upgrade options are limited.

Warranty

The standard one-year limited warranty applies. Please see our Guarantees, Return policies and Warranties article for country-specific information. We're hopeful that Razer will consider two-year warranty in the future as standard much like for laptops from Aorus or EVGA. 

Input Devices

Keyboard

The main QWERTY keys are identical in feedback and material to the keys on the Blade 15. This isn't necessarily positive, however, as we find the keys on the Blade 15 to be too shallow and light especially for a gaming laptop. Keys on competing Ultrabooks like the Spectre x360 13 or MateBook X Pro have firmer feedback when pressed for a better typing experience.

One notable drawback to the Blade Stealth keyboard is its short length due to the side speaker grilles. As a result, the forward slash, Enter, Shift, and Backspace keys have been shortened significantly and so the keyboard can feel a bit cramped to use. At least the Directional keys are full-size which is an uncommon sight on subnotebooks.

A single-zone RGB backlight is included unlike the per-key RGB backlight of the outgoing Blade Stealth generation. Razer says the change was done mainly to improve on battery life. We can appreciate that all key symbols are illuminated unlike on the Blade 15 backlight.

Touchpad

The trackpad (11.1 x 7.1 mm) is larger than the trackpad on the XPS 13 (10.5 x 6.0 cm) while being smaller than the one on the MateBook X Pro (12.0 x 7.8 cm). Its surface is completely smooth with no finger sticking even if gliding across very slowly. Pushing down on its center will not cause any significant flexing issues.

The integrated mouse keys are very shallow in travel with spongy feedback and just a soft audible click when pressed. It could have definitely benefited from firmer tactility for a more satisfactory click.

Display

Users have the option between matte FHD or glossy 4K UHD touchscreen with the promise of individually factory calibrated screens across all SKUs. Our FHD test configuration utilizes a Sharp LQ133M1JW41 IPS panel found on no other laptop in our database. Brightness and contrast ratio are both above average at about 400 nits average and 1300:1, respectively, compared to 300 nits and ~1000:1 on competing models. Colors are vibrant and texts appear crisp with almost no graininess. We can imagine that the glossy 4K UHD option would appear even sharper than our matte unit.

As nice as the screen may be, it has one major shortcoming. Response times are slow for noticeably more ghosting when gaming. In fairness, competing Ultrabooks also have slow black-white and gray-gray response times as well, but since the new Blade Stealth doubles as a small gaming laptop, faster response times are much more desirable. Quick-moving titles like Overwatch suffer more from ghosting when compared to titles like LoL or DOTA 2.

We are able to detect pulse-width modulation on brightness levels up to 24 percent. Thankfully, the frequency is very high and so most users will not notice. The keyboard backlight does not appear to exhibit PWM unlike on the larger Blade Pro.

Uneven backlight bleeding is minimal and generally unnoticeable on our test unit.

Color space covers nearly the entirety of sRGB and approximately 61 percent of the AdobeRGB standard to be almost identical to the Blade 15 and last generation Blade Stealth. Digital artists should find the panel sufficient in terms of gamut and accuracy. The displays on the Dell XPS 13 or Apple MacBook Pro 13 are capable of even deeper colors to satisfy professionals.

Further measurements with a X-Rite colorimeter reveal a very accurate panel out of the box to back up Razer's claim of factory calibration. The average DeltaE values for grayscale and Saturation sit at just 1.3 and 1.11, respectively, to be significantly more accurate than competing systems. Our own attempts to calibrate the panel were fruitless and so an end-user calibration is not needed. Gigabyte offers similar factory calibration benefits for its Aero 15 series as well.

If we are to nitpick, the colors Red and Blue appear to be less accurate than others particularly when at higher saturation levels. Even so, this is only relative as overall color accuracy is excellent.

Display Response Times

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.
       Response Time Black to White
34 ms ... rise ↗ and fall ↘ combined↗ 17.6 ms rise
↘ 16.4 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 88 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.9 ms).

In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 93 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (39.6 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

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 detected 22730 Hz ≤ 24 % brightness setting

The display backlight flickers at 22730 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 24 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 22730 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9266 (minimum: 43 - maximum: 142900) Hz was measured.

Outdoor visibility is above average for an Ultrabook due to the bright display and matte panel to reduce glare. Users who want even better visibility may want to consider the MacBook Pro 13 or Samsung Notebook 9 NP900 as these alternatives have even brighter displays when set to maximum.

Viewing angles are excellent from the IPS panel with no major color or contrast shifting if viewing from extreme angles. Apparent brightness decreases just slightly if not looking directly at the screen.

Performance

Soldered system RAM sits close to the CPU and GPU
Soldered system RAM sits close to the CPU and GPU

Like previous Blade Stealth models, the 2018 Blade Stealth makes use of 15 W ULV Intel CPUs as found on most Ultrabooks. The new model ups the ante by introducing a dedicated Nvidia GeForce MX150 GPU much like on the competing MateBook X Pro or HP Envy 13t. Unlike the Huawei or HP, however, the GPU in the Razer is the faster 25 W '1D10' version instead of the 10 W '1D12' version for improved graphics performance. This fact alone should give the new Blade Stealth a significant advantage against the competition where the slower integrated UHD Graphics 620 is often the only option.

VRAM has also been doubled from 2 GB GDDR5 on the MateBook X Pro or HP Envy 13 to 4 GB GDDR5 on the Razer. Nvidia Optimus is supported for automatic graphics switching and to extend battery life.

Processor

CineBench R15
CineBench R15

The Core i7-8565U will become the de facto ULV CPU of choice for Ultrabooks in 2019. Of the few we've tested so far, the processor in the Blade Stealth is about where we expect it to be in relation to Kaby Lake-R. In short, the performance benefits are minuscule at best when compared to the Core i7-8550U that it replaces.

The more important factor is performance sustainability or how much the processor throttles over long periods. By running CineBench R15 Multi-Thread in a loop, we can see that its initial score of 677 points drops to 626 points by the second loop for a performance dip of just 7.5 percent. In comparison, the Core i5 or i7 in the MateBook X Pro can drop by 10 to 15 percent in the same loop test. Throttling is much less severe this time around especially when compared to the last generation Blade Stealth where its i7-8550U CPU was underperforming.

See our dedicated page on the Core i7-8565U for more technical information and benchmark comparisons.

Storage Devices

M.2 SSD sits adjacent to the WLAN module
M.2 SSD sits adjacent to the WLAN module

Internal storage is limited to a single M.2 slot as expected. Interestingly, Razer has equipped its latest Blade Stealth with a Lite-On SSD whereas all our previous Razer laptops came with Samsung SSDs. We're not sure why Razer decided to switch suppliers this time, but the 256 GB Samsung PM981 on the Blade 15 Base Model is able to outperform the Lite-On drive on our Blade Stealth on nearly all benchmark tests. Most users will likely not notice the difference during use and performance is still comparable to other Ultrabooks.

See our table of SSDs and HDDs for more benchmark comparisons.

GPU Performance

Razer is proud to advertise its "full-power" 25 W GeForce MX150 and we can comfortably say that its performance benefits are tangible. Its GPU is about 15 percent higher than the average MX150 in our database taken from over 40 other laptops. When compared to the slower 10 W GeForce MX150 in the MateBook X Pro, the Blade Stealth GPU is about 35 percent more powerful. In fact, the Razer laptop currently has the highest 3DMark 11 GPU score in our database out of all other laptops equipped with the same MX150 GPU. Users can expect a performance level just 15 percent behind the old Maxwell GTX 960M for significantly improved performance-per-Watt.

As impressive as its GPU may be, it is still easily outclassed by even an entry-level Pascal gaming laptop. The cheap Dell G3 15 with GTX 1050 graphics is about 60 percent faster for vastly superior gaming potential. Upgrading to the Blade 15 with GTX 1060 Max-Q graphics will bring a performance boost of about 200 percent.

See our dedicated page on the GeForce MX150 for more technical details and benchmark comparisons.

Gaming Performance

The GeForce MX150 is optimal for casual gamers or less demanding titles like LoL, Starcraft II, Fortnite, or Rocket League. In the case of Fortnite, users can expect smooth 1080p60 when playing on Medium preset settings. This is impossible on laptops with integrated UHD Graphics without the aid of streaming or a pricey eGPU.

Idling on Witcher 3 shows smooth frame rates with no performance dips to suggest no interrupting background activity.

More demanding titles like Witcher 3 or Rise of the Tomb Raider can also run at 1080p albeit with most settings turned to Low and at 30 to 40 FPS. The Blade 15 or Razer Core eGPU would be better options in this regard.
