Intel NUC11 Cheetah Canyon Extensibility and Video Decoding Capability Test：Up to 4 4K HDR monitors can be connected at the same time, and supports Wi-Fi 6
As a mini PC，Intel NUC11 Cheetah Canyon provides a total of 9 interfaces in front, back, left and right，Extensibility of external hardware devices is not inferior to traditional box desktop computers，Even better。
First, let’s talk about the video output。Intel Iris Xe core graphics provided by Intel NUC11 Cheetah Canyon supports up to 8K 60Hz image output，It has improved a lot compared to the previous generation's only 4K support，This can be said to provide a performance basis for Cheetah Canyon to become a home audio and video center。
in terms of interfaces，It provides 4 video interfaces in total，Two thunderbolts and three、1MiniDP 1.4、1HDMI 2.0b。Two Thunderbolt 3 interfaces are independent of each other，Therefore, two 4K HDR 60Hz monitors can be connected to output images respectively，Reach the output limit of up to 8K for core graphics。
certainly，Since the price of Thunderbolt 3 docking station and Thunderbolt 3 wires are expensive，We don't actually have to use all the Lightning 3 connections，The additional miniDP and HDMI 2.0a interfaces can also play their value，You can choose and use it with your existing wires。
also，HDMI 2.0a interface due to bandwidth limitations，It cannot meet the bandwidth requirements of 8K，So if you want to connect an 8K monitor，It is recommended to use Thunderbolt 3 or miniDP。
In addition to the video interface，Intel NUC11 Cheetah Canyon has many dedicated data interfaces。The Thunderbolt 3 interface can take into account data transmission capabilities while outputting videos.，Maximum speed can reach 40Gbps。3USB 3.1 port，It can also provide connection speeds up to 10Gbps。
also，Intel NUC11 Cheetah Canyon also comes with an SD card reader，Supports reading of up to UHS-II SD cards。We tested its speed，Able to reach 80MB/s，Can meet the daily copying of files by photography enthusiasts。
also，Intel NUC11 Cheetah Canyon also comes with its own microphone，Support voice control function。The author briefly tried the voice control assistant that comes with Windows 10，Good radio effect。
However, the experience of Windows' own voice program is relatively average，Users in need can try to install Xiao Ai’s Windows version and experience more complete functions.。
Intel NUC11 Cheetah Canyon also has a built-in Wi-Fi 6 wireless network card，Simple test of the internet speed，It can easily run in a Gigabit LAN environment。Although the physical interface limits the network speed within gigabit，But as long as it is supported with 2×2 MIMO 160MHz wireless routing，Still able to obtain 2400Mbps protocol speed，Even if the signal is not good, there will be some loss，The internet speed is still considerable。
Decoding capability test：Hard solution to 8K is no problem and supports the new generation of AV1 format
Before testing decoding capabilities，Let's first make a conclusion。If used for audio and video playback，Intel NUC11 Cheetah Canyon is a perfect audio and video computer。It not only supports simultaneous output of up to four 4K HDR units，And it also has corresponding decoding capabilities，4K 60FPS no pressure，There will be no problem with the hard solution of the highest 8K video。
Decode 8K 30 frames of video，Soft solution can barely cope，But there is also a large tremor.，Switch to hard-decoding of core graphics, can run smoothly with full frames；8K 60 frame video core display and hard solution can also run smoothly，However, it cannot reach the native frame rate playback，It can only maintain a maximum of around 44 FPS。As shown below：
also，The Iris Xe core graphics equipped with Cheetah Canyon supports decoding in AV1 format，It can be said that it takes the lead in supporting major video platforms。
What is AV1 encoding? It's by Apple、IBM、Intel、Samsung、Tencent、Adobe、iQiyi and other new video encoding formats need to be jointly developed by multiple giants，Compared with traditional H.265 and other encoding formats，It has two advantages，First, permanently free，Second, it is more efficient。
Free for everyone，No high authorization fees required。More efficient。Under the same picture quality，Lower code rate，This takes up less bandwidth。The two advantages are combined，AV1 coding has undoubtedly become a hot commodity，Used by manufacturers。Although not common nowadays，However, all major factories have made technical reserves and are eager to try。iQiyi has begun to try to use AV1 encoding on mobile，Chrome browser has also completed support for AV1 encoded videos，It's only a matter of time before the full rollout of AV1，It has been accepted by the big companies。
Say it without any hesitation，AV1 encoding is a technology that is always future-oriented，Its popularity is imperative。If you want to experience the improvement of AV1's new encoding for streaming media，Support for hardware decoding is very important。Because the only disadvantage of AV1 is that，Soft solution efficiency is too low，The CPU usage is too high。This time Iris Xe core graphics，It was the first to implement support for AV1 encoding，for users，It can give you the confidence to fight the future。
