Khadas Mind Premium review – Part 3: Ubuntu 22.04 tested on an Intel Core i7-1360P mini PC

Khadas Mind Premium is an ultra-thin mini PC powered by an Intel Core i7-1360P Raptor Lake processor and supports various docks through the Khadas Link connector. We reviewed the mini PC with the Mind Dock in Windows 11 a few weeks ago, and we’ve now had time to install Ubuntu 22.04 to check out the mini PC with Linux. Installing Ubuntu 22.04 on Khadad Mind Premium We decided to install Ubuntu 22.04 alongside Windows 11, so we shrank the Windows partition by about half before inserting a Ubuntu 22.04.3 USB drive to install the Linux distribution. This went smoothly, and in no time we could run Ubuntu 22.04 on Khadas Mind Premium with just two cables, one for power, and the other for the display (both video and power) as we used a wireless mouse and keyboard for user input. Ubuntu 22.04.3 system information The system information in Ubuntu 22.04.3 […]

Khadas Mind Review – An ultra-thin Core i7-1360P mini PC tested with Windows 11

We wrote about the Khadad Mind portable mini PC a few weeks ago with quite a unique design bringing the Intel Core i7-1360P Raptor Lake processor to a super thin design and enabling extension through the Mind Link connector with PCIe, HDMI 2.1, and USB 3.2 Gen 2 interfaces. We’ve now had time to test the Khadas Mind with the Khadas Dock adding 2.5GbE, two HDMI ports, and several 5 Gbps USB connectors, as well as an audio jack and a full-size SD card reader with the Windows 11 Home operating system, so we’ll report our experience that has been mostly positive. Software overview and features testing The Khadas Mind ships with Windows 11 Home 22H2 build 22621.1992 and the System About menu confirms we have a mini PC equipped with an Intel Core i7-1360P processor with 32GB RAM. HWiNFO64 provides more details about the Core i7-1360P processor, Khadas Mind […]

GL.iNet Puli AX (GL-XE3000) WiFi 6 & 5G router integrates a 6,400 mAh battery

GL.iNet Puli AX (also known as GL-XE3000) is a WiFi 6 and 5G cellular router with an integrated 6,400 mAh battery and running a fork of OpenWrt 21.02 on a MediaTek Filogic 820 dual-core Arm Cortex-A53 router SoC. If the design looks familiar it’s because it’s based on the same platform as the GL.iNet Spitz AX 2.5GbE, WiFi 6 and 5G cellular router that we reviewed last May, except the new Puli AX model comes with a 6,400 mAh which makes it even more convenient as a travel router. Puli AX (GL-XE3000) specifications: SoC – MediaTek MT7981A (Filogic 820) dual-core Arm Cortex-A53 processor @ 1.3 GHz System Memory – 512 MB DDR4 Storage – 8GB eMMC flash, MicroSD card slot Networking 1x 2.5GbE WAN Ethernet port 1x Gigabit Ethernet LAN port Dual-band IEEE 802.11a/b/g/n/ac/ax WiFi 6 up to 574Mbps (2.4GHz), 2,402Mbps (5GHz) RM520N-GL 5G cellular modem and 2x Nano SIM […]
