First known for its garish peripherals, Razer has been trying the IT adventure for some time now with expensive but well-finished PCs. The new flagship model of the Californian brand, the Blade 15, focuses as much on finesse as on power.

Our review


With its first Razer Blade, the brand has moved out of its comfort zone and has succeeded in offering products that can be improved, but have their own personality. Same thing with the recent Razer Phone. Since then, Razer has taken the bottle and offers a whole range of PCs, gaming or not.

With the Razer Blade 15.6, the manufacturer has chosen to offer a war machine equipped with a GTX 1070 Max-Q Design in a 1.7 cm chassis. An objective fulfilled, the PC keeping all its promises at stake. Nevertheless, the slimming cure of Razer ends up being paid for, the Blade 15.6 emitting a heat as unpleasant as disturbing in play.



If there is one thing Razer sticks to on his PCs and smartphones, it is his visual identity. For this Blade, we find the chassis as sober as it is angular in black aluminum which characterizes the range. Always a visually flawless finish. To mark its gaming aspect, the PC has just a backlit Razer logo on its cover, nothing more when it is closed.

A design that is changing in the PC landscape for gamers where the escalation of ostentatious grids and LEDs is common. The grilles, precisely, are placed under the PC and at the back of the chassis in order to be as discreet as possible. A more visual choice than practical - we will come back to this.

Once opened, the PC reveals a keyboard similar to that of previous models. RGB, the keyboard can be managed via the Razer Synapse software, preinstalled on the PC. To gain finesse, Razer has chosen to shorten the stroke of its chiclet keyboard as much as possible, which ultimately does not make typing very pleasant. The trackpad is responsive and pleasant to use, which is rare on a gaming laptop.

Connectivity is content with the minimum for a gaming PC. The Razer Blade 15 has a proprietary power outlet, a USB Type-C port, three USB 3.0 ports, a mini-DisplayPort port and an HDMI port, in addition to the traditional headphone port.

It is at the time of examining the heat of the PC with the thermal camera that the Blade reveals its Achilles heel. Indeed, during our usual protocol (Metro Last Light benchmark for one hour), it reaches the maximum temperature of 62 ° C at the rear grille. It's a lot. Likewise, aluminum reaches 54 ° C above the keyboard; it is impossible to place fingers without getting burned. Even worse, the heat is diffused slowly through the chassis, which makes it unpleasant to put your wrist on it in the playing position. Uncontrolled heating, which is done for the benefit of an amazing silence, the PC not exceeding the 45 dB at stake. So bad for good.

Side consumption, the Blade remains in the current average with a consumption of 40 watts on the desk, 155 watts in play and 0 watt in standby.

In short, a PC in the main lines of Razer's machines, but which this time preferred to sacrifice freshness on the altar of heating, and not vice versa.



The 15.6 inch Razer Blade has a 15.6 inch screen with a resolution of 1920 x 1080 px. Razer is betting on two things to extol the merits of its screen: the refresh rate of 144 Hz as well as the ultra-thin edges. The screen-to-face ratio is thus 82.7%, making it the gaming PC with the thinnest edges. It sits right in front of the Aero 15X V8 with its 80.5% ratio.

Scrutinized by our probe, the screen of the Razer Blade 15 reveals correct results, but far from being exceptional. The contrast is thus only 900: 1, a fairly low score which does not allow a good vision of the gray details and which is handicapping in dark games, for example. The temperature is 6,950 K, a correct score relatively close to the 6,500 K reference, a sign of the perfect white balance.

The Razer's screen is distinguished above all by its Delta E which displays an excellent average of 2.2 confirmed by the color table. Thus, the colors delivered by the screen are extremely faithful. The remanence is also excellent, since it is 5 ms. A pleasure in play.



The Razer Blade 15 is equipped with an Intel Core i7-8750H processor supported by 16 GB of RAM. Powerful equipment that should not limit the user.

During our usual test protocol (photo, video, audio compression), the Razer Blade showed its muscles and reached the index of 158 on our scale. It ranks among the best PCs tested by us. Only the MSI GT75 Titan 8 RF, equipped with an Intel Core i9, surpasses it. With such power, the user will have plenty of time to push the PC to its limits and run applications that are very greedy in computing.



The Razer Blade 15 is equipped with an Nvidia GTX 1070 Max-Q card (but it also exists with a 1060 or a 1050, both Max-Q). It therefore seeks to offer in an ultra-thin chassis a really interesting power in play.

During our usual tests (setting in Ultra, vertical synchronization disabled and definition in 1080p), the PC did not fail. Assassin's Creed Origins reached 57 fps, The Witcher 3 82 fps, Civilization 6 75 fps, Star Wars Battlefront 2 94 fps and Metro Last Light 102 fps. The user therefore does not have to worry about the power of his gaming machine and can run all the big softs of the moment in Ultra mode without asking questions.

In terms of pure power, the Razer Blade still shows the limits of the Max-Q Design. It falls short of other equivalent models like the Aero 15 X V8, which is better ventilated. A difference which however is not felt in play.


Mobility / Autonomy

Weighing 2 kg, the Razer Blade is relatively light for a gaming PC. Similarly, its thickness of 1.68 cm almost places it in the category of ultraportables and allows it to be easily transported in a bag. Unfortunately, the power supply, of normal size for a gaming model, comes a little to clutter the congestion. Likewise, the catastrophic autonomy counterbalances this design which relies on lightness and finesse.

Thus, during our usual test (Netflix in Chrome, brightness set to 200 cd / m², headphones plugged in), it went out after 2 hours and 12 minutes. Even for a model for players, it is very little. A disappointing and surprising figure, so much so that we did a second test session to be sure of this result, without seeing any improvement. The user will therefore constantly have to keep his PC plugged in and will not even be able to watch a long film on his Razer Blade 15. A big disappointment.

Update: Following the remark of a reader in comment of the test, we carried out a second autonomy test, but this time adjusting the screen to 60 hertz. The screen of the Razer is by default in 144 hertz and you have to delve into the options to deactivate this feature. Once removed, autonomy improves significantly since it increases to 6 hours and 20 minutes. Always low autonomy, but more in line with other gaming PCs on the market. Surprisingly, other computers equipped with a 144 hertz screen (like the Aero 15 X from Gigabyte) do not know this glaring difference in autonomy when it is deactivated. An anomaly that deserves to be reported. In all cases, you will have to deactivate the functionality in the options to watch series or movies on your Razer Blade. Consequently, the score in the autonomy section has been raised


With its speakers placed around the keyboard, the Razer Blade delivers a bland sound, correct in the mids, but without bass or treble. Add to that an unpleasant compression to the ear as well as too high a distortion, and here is a PC with a sound worthy of a radio. However, voices have the merit of being intelligible, an asset for the game.

The headphone jack is very correct, delivering good results. We note a very high power and excellent dynamics.


With its attractive looks (a successful design, an impressive finesse ...), the Razer Blade 15.6 however fails to offer an experience worthy of its price. If he succeeds in being powerful, the heating is however too annoying to be ignored. If the screen is under control, the default poor autonomy does not allow you to enjoy it without moving away from a socket. In short, Razer still has a little work to succeed, namely to offer an ultra-powerful PC in an ultra-portable chassis.
