The expensive Predator 21 X has a curved 21-inch screen with a 21: 9 aspect ratio, it is equipped with two GeForce GTX 1080 graphics chips, and a laptop has several overclocking modes. This set of parameters is already enough to seriously become interested in this device. For a wiring connection is the Qualcomm Killer E2500 controller – this chip is used in expensive gaming motherboards. The work of wireless connections is provided by the Killer Wireless-AC 1535 module. This adapter supports IEEE 802.11b / g / n / ac standards with a frequency of 2.4 and 5 GHz and a maximum bandwidth of up to 867 Mbps and Bluetooth 4.2.

As I said, the “Predator” is based on the central processor Core i7-7820HK and the pair GeForce GTX 1080. Also in the laptop is installed 64 GB of RAM DDR4-2400, two SSDs totaling 1 terabyte, united in an array of RAID 0, and hard disk for 1 terabyte.
I usually do not pay any attention to the laptop package, but in the case of 21 Predator X would have to make an exception. Just out of the store you pick a device that’s in a plastic case on wheels, which not afraid of any weather woes, nor carelessness host. “Packaging” with a laptop together weigh about 25-30 kg.
Together with the Predator 21 X, the following accessories are in the suitcase: Gaming Laptop acer predator 21x Review Specs 2018?
- Two external power supplies with a power of 330 W and a weight of 1.5 kg each.
- A rubber frame for combining two power supplies into one array.
- Replacement keys WASD.
- Wrist rest.
- A heap of all waste paper.
- Company badge.
- Digital versions of Prey games, Mass Effect: Andromeda and Tom Clancy’s Ghost Recon Wildlands.
The first buyers of the laptop will additionally receive a firm mat, a mouse and a Predator headset. Finally, for the maintenance of the device by the technical support service, a personal manager of Acer is selected, ready at any time to consult the owner of Predator 21 X.
PredatorSense also preinstalled the program. With its help, the user can:
- Customize the backlight of the keyboard, as well as four separate areas of the laptop.
- Select one of the two profiles for overclocking the CPU and graphics.
- Configure hotkeys and set macros.
- Select the operating mode of the built-in laptops.
- Track the temperature of the CPU and GPU.
Design and Ports
The laptop really looks unusual, but not only because of the dimensions that that the soul scream is very impressive. Simply even in the closed state you can see that something is wrong with the Predator 21 X screen. Until now, there was no laptop with a concave display in nature. Entourage adds and the aspect ratio – 21: 9 (my favorite, by the way). If it were not for the bizarre forms in the fashionable now style, because of which many gaming laptops resemble the illegitimate children of a racing car and a space ship, the Predator 21 X would be quite like half of a rugby ball. Complement the extravagant appearance of the laptop logo and stripes on the sides of the covers that glow with all the colors of the rainbow.
Weight – decent: as much as 8 kg, and in fact with itself it is necessary to carry two more power units of 1.5 kg each. Dimensions are also impressive, since the thickness of the device is neither much less than 83 mm. Against the backdrop of Predator 21 X, such 17-inch models as ASUS ROG G701VI and MSI GT73VR 7RE Titan SLI , look like a half-dead anorexic.
The cover of the laptop opens approximately 130 degrees. In the design of “Predator” very tight loops are used, but a slight play is still present – because the screen of Predator 21 X is very heavy. The radius of curvature of the display in the laptop is small.
There are no elements on the front panel. Because of the concave screen, you can even see the keyboard with the lid closed. At the rear are less used HDMI connectors, two DisplayPort, RJ-45 and Thunderbolt 3, combined with USB 3.1 Type-C, as well as two connectors for connecting power supplies. On the left, the Predator has two USB 3.0 A-type ports, a card reader (supports SD, SDHC, SDXC formats) and two 3.5 mm mini jacks for headphones and a microphone. On the right – two more USB 3.0 and a slot for the Kensington lock.
The Predator 21 X has an interesting panel with keys. Firstly, the buttons themselves are shifted closer to the user, and the touchpad took the place in the lower right corner. The original move, although laptops with this location HID are found in ASUS and MSI. Secondly, through the transparent glass we see a fan. Over time, when the impeller is clogged with dust, the appearance of the laptop will fade somewhat, but it will only happen later. But the glass will get dirty just after a couple of days , because every speck of dust is visible on it. Thirdly, the panel is decorated with a trapezoid plate with the inscription “Conquer new world” and a dragon image. It is its owner Predator 21 X that can be completely changed for something its own.
One of the advantages of Predator 21 X, of course, is the use of a mechanical keyboard with switches Cherry MX Brown. In most modern notebooks, however, a scissor mechanism is used. “Brown” switches are great for typing and playing games. Pressing is made clearly, but loud enough. The keyboard is equipped with a single-level RGB-backlight.
There are no complaints about the layout of the laptop, the keys are large and convenient. Buttons of additional functions, activated via the Fn-modifier, are located successfully. At the same time, it’s better to work and play with the keyboard with a wrist rest. In addition, due to the very close arrangement of the buttons, you have to push the laptop away from you as far as possible.
To the left of the main keys is a block with programmable buttons “1” – “5”. They are configured in PredatorSense. On the right is a removable unit with a touchpad and a digital module. In the niche, it is held by a magnet. The design looks original, and the ability to use a digital unit instead of a touchpad can really be a good idea, because a game mouse is most often connected to a gaming notebook.
What is unpleasantly surprised in the Predator 21 X, is the use of an openly dull webcam with a resolution of 720p and a frequency of 30 Hz. 720p? In general, the quality of the image “webcam” is enough except for communication with Granny by Skype, but definitely not for streaming and recording of floppy disks.
What was pleasantly surprised is the ability to freely access all the system components that can be replaced.
Thus, a removable hatch is provided on the bottom of the laptop. We unscrew three screws and get access to two solid-state drives Samsung MZVKW512HMJP in volume of 512 Gbytes each. SSDs are integrated into RAID 0 array and equipped with aluminum radiators. To the left of them are two more ports M.2, therefore, the number of solid-state drives in the laptop can be doubled. Here, two Kingston ACR24D4S7D8MB-16 modules are installed in SO-DIMM slots, operating at an effective frequency of 2,400 MHz with delays of 17-17-17-39.
To the rest of the iron – two more RAM modules and a hard drive HGST HTS721010A9E630 of 1 TB – to get even easier. To do this, remove the plate with the image of the dragon, after unscrewing one screw. A screwdriver with a hexagonal slot is included. But to get directly to the processor and mobile graphics, will have to disassemble half of the laptop. Do it for obvious reasons, I did not.
It is known that five fans are used in the cooling system. The central processor is cooled by three heat pipes. The same number of elements are per GPU.
In principle, there is no need to upgrade the Predator 21 X. Unless the mechanical drive HGST can eventually be replaced with another SSD of 1-2 TB. Gaming Laptop acer predator 21x Review Specs 2018?

Performance in games was determined using the well-known program FRAPS. With its help, we get the rendering time of each frame. Then, using the FRAFS Bench Viewer utility, not only the average FPS, but also the 99th percentile is calculated. The use of the 99th percentile instead of the minimum frames per second is due to the desire to clear the results of random bursts of performance that were caused not by the causes directly related to the work of the main components of the platform.
Measurement of processor and memory performance was carried out using the following software:
- Corona 1.3 . Test rendering speed with the help of the same rendering. The speed of building a standard BTR scene used to measure performance is measured.
- WinRAR 5.40 . Archiving a folder of 11 GB with different data in RAR5 format and with the maximum compression ratio.
- Blender 2.76 . Determine the speed of the final rendering in one of the popular free packages for creating three-dimensional graphics. The duration of construction of the final model from Blender Cycles Benchmark rev4 is measured.
- x265 HD Benchmark . Testing the speed of video transcoding to the perspective format H.265 / HEVC.
- CINEBENCH R15 . Measuring the speed of photorealistic 3D rendering in the animation package CINEMA 4D, CPU test.
The display is tested using the X-Rite i1Display Pro colorimeter and the HCFR application. Gaming Laptop acer predator 21x Review Specs 2018?
The battery life of the laptop is tested in three modes. The first version of the load – web surfing – involves the sequential opening and closing of tabs of 3DNews.ru, Computeruniverse.ru and Unsplash.com with an interval of 30 seconds. This test uses the Google Chrome browser with the “Block third-party sites and cookies” and “Do not allow sites to save data” options. In the second mode, x265 (HEVC) video is played in the standard Windows 10 player with the activated repeat function. The third type of load is the launch of the Unigine Heaven benchmark on the maximum graphics quality settings in full-screen mode. In all three cases, the same display brightness was set at 200 cd / m 2 .
In games and other applications, the Acer Predator X21 was compared with the following notebooks.
Display and sound
Two or three years ago many manufacturers of TVs bet on the models with concave (I specifically avoid the epithet “curved”, since the ancient devices with the EL-tube were also curved, only in the other direction) with displays. For example, the flagship 9000 series of Samsung SUHD TVs, introduced in 2015, consisted entirely of models with such screens. The test laboratory is constantly studying monitors with concave displays. The marketing machine is working, and during this time the producers managed to tell us about the “incredibly large immersion”, “increasing the viewing angles and reducing the contrast loss”, “reducing reflections,” “increasing the visual area of the screen,” “reducing optical distortion,” and many more, a lot of things are interesting. Only from my experience I can tell you the following: in most cases, a concave screen in a TV or monitor is used exclusively as a designer move. Because even in 2017 this device looks unusual and fresh. Here and at 21-inch “Predator” the concavity of the display is not felt. Or almost not felt.
The display for Predator 21 X was made by AUO. Matte IPS-matrix AUO10FA has good indicators of brightness and contrast. Thus, the minimum luminance level of white is 19 cd / m 2 , and the maximum luminance level is 424 cd / m 2 . The contrast ratio of 1221: 1 will allow you to fully enjoy both games and films.
However, calibrate the display of comrades from Acer and AUO could have been better. Measurement with a colorimeter showed that the color temperature of the screen in the whole range is higher than the reference mark of 6500 K and corresponds to the parameter of ~7,700 K, although in general the stability of the shades of gray is at a good level. Gamma 2.26 is almost completely consistent with the reference value of 2.2. The color coverage of the AUO10FA is significantly larger than the sRGB standard and approaches AdobeRGB, but the average deviation of the DeltaE on the gray scale is 8, with a maximum of 15. The average difference in the ColorChecker24 test was 4.64 with a maximum value of 7.59.
I was pleased with the wide viewing angles in all planes, as well as the lack of PWM at all brightness levels – or its frequency is too high and invisible to the human eye. However, the Glow-effect, characteristic for the absolute majority of IPS-matrices, is present. It is well visible on the black fill. I did not see any noticeable light at the edges of the screen.
In general, the display Predator 21 X I liked rather than did not like. The volume of volume at the “Predator” is decent. When playing music, there are no rattles and other artifacts. The low and high frequencies sound very bright, but the middle part slightly “falls through”. If you evaluate the sound quality of Predator 21 X by laptop standards, then the sound of the laptop is very good. Gaming Laptop acer predator 21x Review Specs 2018
“Predator” is configured in such a way that under serious load the system immediately resets frequencies, not allowing the processor to overheat. In the modes “Faster” and “Turbo”, in addition to increasing the frequency of the CPU, the limit of its maximum permissible temperature also increases. So, without any overclocking, the maximum temperature of Core i7-7820HK reached only 83 degrees Celsius, and then the chip began to reset the frequency from 3.5 to 2.9 GHz, that is, Turbo Boost switched off. In the “Faster” and “Turbo” modes, the Predator 21 X processor worked somewhat faster: with frequencies of 3.6 and 3.7 GHz, respectively.
CPU, RAM and disk subsystem performance
The central processor Core i7-7820HK is used in many top-end notebooks. For example, recently the test lab studied the ASUS ROG G701VI and MSI GT73VR 7RE Titan SLI models , in which this chip is decoupled . Of course, an ultimatum combination would be the use of a full desktop Core i7-7700K with a pair of GeForce GTX 1080, but for some reason large laptop manufacturers avoid such a modification.
|Intel Core i7-7820HK (MSI GT73VR 7RE Titan SLI)||Intel Core i7-7820HK (Acer Predator 21 X), the mode “Normal”||Intel Core i7-7820HK (Acer Predator 21 X), the mode “Faster”||Intel Core i7-7820HK (Acer Predator 21 X), mode “Turbo”||The increase in the performance of the “Normal” mode,%||Increase in the performance of the “Turbo” mode,%|
|Corona 1.3, with (less – better)||267||271||236||227||13||16|
|WinRAR 5.40, with (less is better)||442||459||421||411||8||10|
|Blender 2.76, with (less is better)||304||313||267||254||15||19|
|x265 HD Benchmark, FPS (more – better)||16.4||16.2||18.9||19.9||17th||23|
|CINEBENCH R15, points (more – better)||768||755||881||920||17th||22|
Well, the Core i7-7820HK is studied far and wide. The standard DDR4-2400 memory with delays 17-17-17-39 helps the CPU, and therefore in the default mode of operation Predator 21 X does not “stand out from the crowd” in terms of speed. But in overclocking the laptop is changing and coming close to the just mentioned Core i7-7700K.
Two GPU mobile version of the GeForce GTX 1080 is the fastest combination that you can find in a gaming laptop in 2017. Up to this point, the fastest laptop that we had on testing was the MSI GT73VR 7RE Titan SLI with two mobile GeForce GTX 1070s. The King is dead, long live the King! Now let’s focus on the performance of the Predator.
Strictly speaking, I will compare the Predator 21 X with the GT73VR 7RE Titan SLI. For example, in 3DMark Time Spy, the Acer laptop is ahead of the MSI notebook by 19% in the “Normal” mode. Just do not forget that the Predator 21 X is three times the GT73VR 7RE Titan SLI.
In general, the so-called resolution WFHD (2560 × 1080 points) for a pair of GeForce GTX 1080 is quite “easy”. Below is a table with average and minimum FPS, and in all games the Predator 21 X demonstrates a playable frame rate at the maximum or almost maximum graphics quality settings. Only in a number of cases a couple of Pascal flagships are not able to reveal their full potential. This is clearly visible in games such as GTA V, Total War: WARHAMMER and Deus Ex: Mankind Divided. And the final result may well “rest” on the speed of the CPU, and not all games are well optimized for working with SLI technology.
|Acer Predator 21 X|
|Quality of graphics||1% min FPS||Avg FPS|
|“The Witcher-3: Wild Hunt”||FHD||68||104|
|Ghost Recon Wildlands||FHD||46||69|
|Rise of the Tomb Raider||FHD||34||56|
|Total War: WARHAMMER||FHD||71||88|
|Deus Ex: Mankind Divided||FHD||41||66|
|Sid Meier’s Civilization VI||FHD||41||59|
In general, I am a supporter of the ratio of 21: 9. This format is good not only for watching movies and working with Excel spreadsheets. Playing in the resolution of 2560 × 1080 is very interesting – especially in sports and racing simulators, RPG and strategy. However, even in 2017, not all titles are well optimized for WFHD resolution. For example, Fallout 4 refused to run at a resolution above 1280 × 500 pixels. In some games, black bars appear on the sides. For example, in “The Witcher-3” a cropped picture is observed during dialogues. e.
