16 inches and just over 1kg?This is the ideal large-screen office artifact

With the help of AMD Ryzen processor, Acer Legend Edge 16 packs a 16-inch large screen into an ultra-lightweight body of just over 1kg. It can be said to be the ideal large-screen office notebook. The new Acer Legend Edge 16 maintains the industrial design of the previous generation and upgrades the AMD Ryzen 7 7840U low-power processor platform to further improve performance.

The body thickness of this machine is only 12.95mm, and the edges of the body do not adopt a slim-looking wedge design, but have flat flat edges. Even so, this machine is very slim when viewed from the side, and it doesn’t have the bulky feel of a large notebook.

The Acer Legend Edge 16 has a very complete interface configuration. The right side of the fuselage is equipped with a security lock hole, a USB 3.2 Gen 2 Type-A, a 3.5mm headset jack and a MicroSD card slot. The left side of the fuselage is equipped with 2 USB Tyep-C interfaces, 1 HDMI 2.1 interface and 1 USB 3.2 Gen 2 Type-A that supports shutdown charging.

The keyboard of Acer Legend Edge 16 feels good, with long key travel and quick rebound, making typing very comfortable. The full-size keycaps and wide enough key spacing ensure input efficiency, and with the secondary white backlight, input can be smooth even in dark light environments.

Acer Legend Edge 16 is equipped with a 16-inch ultra-clear OLED large screen, 3200×2000 ultra-high-definition resolution, and a ratio of 16:10.

It has a 120Hz refresh rate and can switch to 60Hz. And from the actual test, this screen has a true 120Hz refresh rate, not overclocked to 120Hz, so the refresh rate test performance is very stable, unlike some overclocked 120Hz screens that have an unstable refresh rate.

As an OLED screen, it has passed DisplayHDR True Black 500 certification and has a very high screen brightness. The default measured value is 408.71 nits. After turning on HDR, the maximum brightness can reach 637.93 nits. The high dynamic range can greatly improve the viewing experience.

In terms of color gamut coverage and color gamut volume, OLED screens are inherently better than LED screens. The measured color gamut of the Macro Legend Edge 16 screen covers 100% sRGB, 99.9 DCI-P3, and the color gamut volume is 182.1% sRGB, 129% DCI-P3. The color gamut range is extremely wide, and the color display effect is delicate and rich.

Comparing the sRGB color gamut chart, we can see that the dotted line part is the reference area, and the colored line part is the actual color gamut area of ​​the Macro Legend Edge 16 screen. It can be seen that the screen color gamut completely covers the reference color gamut range and greatly exceeds the reference range. This allows for very detailed color effects.

OLED screens also have excellent performance in color accuracy. The measured average color accuracy ΔE is 0.5, and the maximum is only 1.28, which shows that the color deviation of this screen is extremely low and the color reproduction is accurate.

Interested friends can refer to the color accuracy chart below to see the accuracy of the display of various colors on this screen. I won’t go into details here.

In terms of RGB grayscale balance, the performance of this screen can be said to be quite good. It can be seen that between the brightness of 0-100, the overall deviation of the red, green and blue colors is not too high. When the brightness is only 20%, the overall deviation is not too high. Off-center, at 5%, 45%, 50%, 60%, 65%, 85%, 90%, 95%, and 100% brightness, RGB has reached an almost perfect balance, and the display effect is truly amazing.

The Acer Legend Edge 16 has been upgraded from the previous Ryzen 7 6800U to the Ryzen 7 7840U. Its memory is 16GB LPDDR5 and the hard drive is a 512GB PCIe4.0 solid-state drive. In addition, the GPU has also been upgraded to Radeon 780M.

As a high-end model among AMD U-series low-power processors, the Ryzen 7 7840U processor adopts the new Zen 4 architecture, the leading 4nm process, has an 8-core 16-thread design, a default frequency of 3.3GHz, an acceleration frequency of 5.1GHz, and L2 +L3 cache capacity is 24MB, configurable cTDP is 15-30W.

Let’s take a look at single-core and multi-core performance first.

First of all, under the CINEBENCH R23 test standard, this processor scored 1733pts in single core and 12078pts in multi-core. Compared with the Ryzen 7 6800U processor configured in the previous generation model, the single-core improvement is 18.94% and the multi-core improvement is 20.21%. It is not easy to achieve such a high improvement when the number of cores is the same.

Secondly, referring to the 3DMark CPU PROFILE test standard, this processor scored 987 points for single thread, 1894 points for 2 threads, 3353 points for 4 threads, 5268 points for 8 threads, 5799 points for 16 threads, and 5773 points for the maximum thread. The overall performance is excellent. This makes Acer Legend Edge 16 more capable when dealing with various office applications that focus on multi-threaded tasks.

The Ryzen 7 7840U processor has a cTDP of 15-30W. The Acer Legend Edge 16 adopts a lightweight design, so power consumption release must be taken into consideration. Through the AIDA 64 FPU single-bake test, we can see that the processor’s stable power consumption is 20W and the core temperature is 62.5°C. During the test, we switched it to high-performance mode through the Fn+F keys. Obviously, the adjustment is still a bit conservative.

Although the power consumption seems to be 3-5W lower than that of the previous generation, it must be said that the energy efficiency performance of this generation of Ryzen is really excellent. The power consumption of 20W far exceeds that of the previous generation of Ryzen 7 6800U processor23 The performance released by -25W power consumption is really the ultimate in existing process technology for thin and light notebooks.

DDR5 memory and PCIe4.0 solid-state drives have now become standard features for notebook computers. The Acer Legend Edge 16 is equipped with 2×8GB LPDDR5 memory. According to AIDA64 testing, its memory read speed reached 50396MB/s and its write speed reached 88798MB/s. , the copy speed is 67724MB/s, the delay is 114.5ns, the delay is slightly higher, but the read and write copy speed is very fast.

In terms of hard drive, this machine is equipped with a 512GB PCIe4.0 solid-state drive. The measured Q8T1 sequential read speed is 7104.88MB/s and the write speed is 5002.83MB/s. The 4KQ1T1 random read speed is 57.6MB/s and the write speed is 57.6MB/s. is 144.7MB/s, reaching the high-end performance level of PCIe4.0 solid-state drives.

For comprehensive performance, we refer to the PCMark10 office mode test. Commonly used basic functions, including Web browsing, video conferencing, application startup, etc., scored 10556 points. There is no problem in completing basic office tasks; the productivity project test scored 10078 points, indicating that it has high efficiency. Spreadsheet and document work performance; in terms of digital content creation, its score is 8302 points, indicating that it can complete pictures, videos, graphics rendering and other tasks very efficiently; its overall score is 6878 points, and its overall productivity performance is very good. As an office workhorse There is no problem with the machine at all.

Finally, let’s look at battery life.

Acer Legend Edge 16 is equipped with a 54Wh lithium battery. During the test, we adjusted the screen brightness of the machine to 70%, the refresh rate to 60Hz, the system volume to 30%, turned on Wi-Fi, Bluetooth, and turned on the energy-saving mode. Under the PCMark battery life standard test, the machine has a battery life of 8 hours and 4 minutes from 99% battery to the remaining 5% battery, which is no problem to meet the needs of unplugged office work for a day.

·Evaluation summary

With its large screen, thinness, portability, and good performance experience, it can be said to be an ideal business notebook. The new generation of Macro Legend Edge 16 inherits the characteristics of the previous generation and improves the performance. It is very suitable for business office users who need large screens. However, the new generation of products has not yet been launched in China. Friends in need can consider the previous generation of products. The overall experience is also very good.
