Performance
The Beelink GS-King X is powered by the Amlogic S922X-H SoC., the same processor found on last year’s GT-King Pro. It contains 4 cores of Cortex A73 clocked at 2.21GHz, 2 cores of Cortex-A53 clocked at 1.8GHz, and a beefy Mali-G52MP6 GPU clocked at 846MHz. There’s also 4GB LPDDR4 RAM under the hood to take care of multi-tasking.
Having tested the GT-King Pro, I was returned with predictable results in the benchmarks I threw at the GS-King X. While these numbers might not seem impressive to you, especially when compared to modern flagship smartphones and tablets. In the world of TV boxes, probably the only device beating the GS-King X in terms of horsepower is the Nvidia Shield TV.
The GS-King X is extremely smooth. Even with the HDMI output set at 4K@60Hz, I rarely experienced any hiccups, lags or delays when navigating through homescreens and settings, launching and switching between apps, loading image-heavy webpages.
As a pure media streamer, the GS-King X does as well as, if not better than, most competitions, thanks to the Advanced Video Engine Gen10 VPU integrated into the Amlogic S922X-H processor. In the Antutu video tester benchmark, the GS-King X scored 1072, out of the 30 tested items, only two video codecs were not supported.
I also played many videos of different formats in Kodi and MX Player, the GS-King X rarely struggled with anything I threw at it. Like last year’s GT-King Pro, the GS-King X supports Advanced HDR10, HDR10+, HLG, and PRIME HDR, with the right videos and a nice HDTV, it is capable of delivering satisfying video playback experiences.
I haven’t encountered even the slightest of problems streaming 4K videos in the YouTube TV app or in Chrome. Only when I switched the resolution to 8K (in Chrome) did I notice serious lags and delays. Since the GS-King X can only output resolution up to 4K, there’s no point streaming 8K anyway.
Unfortunately, although the GS-King X supports the highest Widevine L1 DRM, you won’t be able to stream high-definition videos in Netflix and Amazon Prime Video, probably due to license issues. This might potentially be a deal-breaker for many devoted Netflix fans, and really a shame given how capable the hardware is.
The GS-King X is not designed to be just a streaming box. The mali-G51MP6 has enough power for most games you can find in Play Store. In the 3DMark app, the device notched 1608 and 1187 respectively in Slingshot and Slingshot Extreme tests.
I tried many games, including some of the most demanding titles on the GS-King X, most of them ran smoothly at moderate settings. But if you want the highest level of visual effects, you should expect some frameskip and even serious delays. A joystick is necessary if you intend to use the device as a gaming console.
Audio
The GS-King X also features dual ESS ES9018 HiFi DAC, which offers DNR up to 135dB, –120dB THD+N, and enables the box to drive headphones with high impedance (up to 600?). I plugged in my HiFiMan HE300 headphones and listened to a lot of music during the three weeks of testing, the sound coming from the GS-King X was significantly better than the that from my computer or smartphone. The GS-King X offers a 3.5mm headphone jack, RCA ports, and BAL ports for users to enjoy audio enhanced by the HiFi DAC.
The S922X-H processor has DTS Listen and Dolby Audio licenses, and the box itself is compatible with 7.1 audio systems. If you happen to have speakers certified by Dolby or DTS, you will be able to enjoy discrete surround sound from movies encoded with Dolby and DTS audio. The box features an optical SPDIF port for transmitting 7.1-channel audio,
Connectivity
The GS-King X offers lots of connectivity options. It supports 2.4GHz/5.8GHz dual-band Wi-Fi, but not the latest WiFi 6 or Wi-Fi 6+. Fortunately, the box has solid reception and is able to pick up more Wi-Fi hotspots than most of my older TV boxes and mini PCs. The 1000M Ethernet jack also comes in handy whenever I want enhanced stability and even higher bandwidth. There’s also Bluetooth 4.1 on board to take care of local file transfer and pairing with audio and input devices, saving u from all kinds of annoying wires. When connected with speakers and headphones, the supported codecs are SBC and AAC, you won’t get superior codecs like aptX or LDAC.
The HDMI 2.1 port on the GS-King X can output videos up to 4K@75Hz, and should support most TV sets, monitors and projectors. In comparison, the Nvidia Shield TV and many other TV boxes are still using HDMI 2.0 or HDMI 1.4 ports.
Verdict
The GS-King X is an interesting device with many fancy features and a ton of potential. But Beelink needs to work hard to improve the NAS service and make it more affordable to its users.
At $289, the Beelink GS-King X is a lot pricier than last year’s GT-King Pro ($145), which runs on the same processor and serves identical TV box functionalities. But the GS-King X does have its advantages. Besides dual HDD NAS, it also offers more ports, and has an active cooling system to prevent overheating. But are these features worth digging deeper into your pocket? Different people will surely have different answers.
For average consumers who just want a top-of-the-line TV box for video streaming and occasional gaming, I would still recommend the GT-King and GT-King Pro, both of which can handle TV box tasks as well as the GS-King X. Even if storage is important to you, please do not forget that these boxes are also able to mount mobile drives of up to 4TB, only that you won’t be able to use them as NAS devices.
