AMD Ryzen Embedded SBC Review with Ubuntu 20.04

Last June, we reviewed DFI GHF51 Ryzen Embedded R1606G SBC with Windows 10 Enterprise LTSC. We had to send back the board to Taiwan, as the company wanted to double-check some of the issues we reported, and we got the board to review it with Ubuntu 20.04. So I downloaded Ubuntu 20.04.1 ISO flashed it to a USB flash drive, and could install it on the eMMC flash drive without issue. I selected to keep Windows 10, so I have a dual-boot system on a 32GB eMMC flash. Yes, I do like a challenge! 🙂 DFI GHF51 Ubuntu 20.04 System Info We can check some of the information from the system in the terminal: So I have a 7.9GB partition to play with Ubuntu 20.04.1, but I could do all tests without issues, although I had to remove Phoronix benchmark program and data after completing the benchmark. Features Testing There may also be some issues with drivers, so I tested …

Beelink Gemini T45 Pentium N4200 Mini PC Review

No sooner had I written ‘Beelink T45 Review with Windows and Linux, and Tweaking BIOS Power Limits’ than Beelink announce they wouldn’t in fact sell that configuration but an ‘updated’ version. And it is significantly different because this new version is now actively cooled and uses an Apollo Lake N4200 processor. It also still has the same name: the Beelink Gemini T45. I’ve now reviewed this new version and you may experience déjà vu on reading the following as in keeping with Beelink’s philosophy I’ve basically reused the same text as before and just updated where appropriate. Beelink have further extended their ‘Gemini’ range of mini PCs by adding the T45. This is an actively cooled mini PC that uses the slightly older Apollo Lake Intel Pentium N4200 CPU which is a quad-core 4-thread 1.10 GHz processor boosting to 2.50 GHz with Intel’s HD Graphics 505. The T45 is a ‘NUC’ style mini PC physically consisting of a 119 x …

A Look at Ubuntu on MINIX NEO G41V-4 and J50C-4 Mini PCs

MINIX Technology Limited recently released two new Gemini Lake mini PCs running Windows 10 Pro namely the MINIX NEO J50C-4 actively-cooled mini PC with an Intel Pentium Silver J5005 processor and the MINIX NEO G41V-4 fanless mini PC powered by an Intel Celeron N4100 processor. Whilst each mini PC comes with 64GB of eMMC with pre-installed Windows 10 Pro together with 4GB of RAM they also support the addition of an optional 2280 M.2 drive and the MINIX NEO J50C-4 allows optional memory upgrades. Prior to testing their performance under Ubuntu, I established a comparison baseline by updating Windows to version 1903 and then running my standard set of benchmarking tools first with the default configuration of each mini PC and then repeated having installed the official MINIX 2280 M.2 240GB drives for each device together with adding an extra 4GB RAM to the MINIX NEO J50C-4. The results can then compared them with other Intel mini PCs: Then for …

Intel Mini PCs Linux Performance Comparison

Recent vulnerabilities in Intel x86 microprocessors (Meltdown, Spectre, Foreshadow, RIDL, Fallout, ZombieLoad, etc.) are now addressed with mitigation patches for the Linux kernel although have resulted in some performance degradation. As a consequence, my previous comparison benchmarks could be somewhat misleading when compared with new results given the different versions of software at the time of execution. So I’ve repeated running my standard Phoronix Test Suite benchmarks on several of the latest mini PCs each running the latest updated Ubuntu 18.04.2 software with the same Ubuntu 4.15.0-54 kernel. Specifically, the mini PCs I’ve used are as follows: Intel NUC NUC7CJYSAL (Celeron J4005 Gemini Lake) Pepper JobsGLK-UC2X (Celeron N4100 Gemini Lake) Beelink Gemini X X45 (Celeron J4105 Gemini Lake) Beelink Gemini X X55 (Pentium Silver J5005 Gemini Lake) with updated BIOS Intel NUC NUC7PJYH (Pentium Silver J5005 Gemini Lake) Beelink L55 (i3-5005U Broadwell) On each mini PC, I’ve also run sbc-bench which is a small set of different CPU performance tests focusing on …
