Networks, Storage, RAM and Ports

As for network adapters in the Beelink Gemini X55 Ultimate mini PC, we have an Intel 3165D AC Wireless Dual Band Adapter with integrated Bluetooth 4.2 and Gigabit Ethernet port. We pass mSATA disk storage speed tests installed by default and observe that it behaves normally. We also tested the 8GB of LPDDR4 RAM 2133MHz that comes standard in Dual Channel configuration with correct performance for this type of memory.

Processor, performance and thermal

Inside the Beelink Gemini X55 Ultimate mini PC we find an Intel Pentium Silver J5005 processor with four cores and four threads running between 1.5 and 2.6 GHz and an Intel HD Graphics 605 GPU up to 800 MHz with 18 EU. This chip has a maximum consumption of 10 W TDP, the results are correct within the Apollo Lake family and as we see it is at the level of more modern models with similar consumption. A mini PC that works perfectly for browsing, multimedia playback with KODI, use of office automation at the user level or even with design applications at the basic level.

  • Game performance: LOL 58ºC / CPU 1.9 GHz on average and 2.7 GHz maximum.
  • Overclock: Available but we do not recommend touching the BIOS.


In our benchmark with games the Beelink Gemini X55 Ultimate have the classic results in the line of this type of products, the Intel HD Graphics 605 GPU is perfectly valid for simple games such as those we can find in Android phones downloading them from the Microsoft Store. At the level of emulators at the most we stay in some simple Wii titles. We can also play smoothly 3D light games like LoL or similar, not enough power to play AAA games with demanding 3D.

  • GTA V / Overwatch / Fortnite, low settings, 720p resolution and no VSync.
  • LOL / CS:GO, ow settings, 1080p  resolution and no VSync.

Playback test

In the video playback aspect the Beelink Gemini X55 Ultimate mini PC with the integrated Intel HD Graphics 605 have a VPU with hardware support for the HEVC codec and for basic VP9, in this processor we have support for 10bit color video and also HDR although we can reproduce it in basic color quality since Gemini Lake does not have HDR with native support. This mini PC is perfectly valid as a multimedia system to use KODI or PLEX.

As we have seen in the review, the Beelink Gemini X55 Ultimate is a very complete miniPC in NUC format, it stands out for its compact size and for the possibility of expanding its internal storage. A small computer that can be valid for desktop use, browse intensively or run design applications at the basic level. This model has 8GB of RAM soldered on board and allows us to also install a 2.5″ disk, certainly very flexible despite its size.

The Beelink X55 Ultimate mini PC has an internal fan that keeps temperatures low and although it does not have semi-passive operation it is quite silent. At the level of network use the Wifi aC adapter behaves normally and we have a Gigabit Ethernet so we are well covered. The connectivity options are good with several USB ports and we like its dual HDMI 2.0 4K@60fps output where we can connect two monitors simultaneously.

The Beelink Gemini X55 Ultimate as we see is an interesting and compact computer, a good low-consumption mini PC model for desktop use or multimedia playback of a very compact size.
