Khadas Mind Maker Kit review – Part 2: Windows 11 Pro on an Intel Core Ultra 7 258V AI mini PC

I’ve already gone through the specifications and an unboxing of the “Khadas Mind 2 AI Maker Kit” powered by an Intel Core Ultra 7 258V “Lunar Lake” processor delivering up to 115 TOPS of AI performance and equipped with 32GB LPDDR5X RAM and a 1TB M.2 NVMe SSD in the first part of the review. I’ve now spent time with the mini PC/developer kit which is now simply called “Khadas Mind Maker Kit”, and I will report my experience with the Windows 11 Home 24H2 operating system in the second part of the review testing features, running benchmarks including an AI benchmark, evaluating networking and storage performance, testing the thermal design while under stress, and taking measurements for fan noise and power consumption. It looks like some AI features may finally be usable on Windows, but I’ll test that in a separate post since everything is new and Microsoft Copilot+, […]

Orange Pi CM5 “Tablet” Base Board drops Ethernet for WiFi 5, adds battery support, M.2 socket, 26-pin GPIO header…

The Orange Pi CM5 was launched as an alternative to Raspberry Pi CM4/CM5 last July with a Rockchip RK3588S octa-core Cortex-A76/A55 SoC, up to 16GB LPDDR4x, 256GB eMMC flash, and three board-to-board connectors maintaining partially compatibility with the Raspberry Pi Compute Module 4. At the time, Orange Pi also introduced the Orange Pi CM5 Base Board with HDMI 2.1, one Gigabit Ethernet port, two 2.5GbE ports, USB 3.0/2.0 ports, four camera connectors, and more. The company has now launched the Orange Pi CM5 “Tablet” Base Board without Ethernet ports, making use of WiFi 5 and Bluetooth 5.0 for networking instead. It keeps many of the same features but adds a 26-pin GPIO header, an M.2 Key-M socket for SSD storage, DP 1.4 and MIPI DSI display interfaces, and various audio interfaces. However, it does with “only” three camera interfaces. It’s quite thick to be used in a typical tablet, but […]

iKOOLCORE R2 Max review – Part 2: 10GbE on an Intel N100 mini PC with OpenWrt (QWRT), Proxmox VE, Ubuntu 24.04 and pfSense 2.7.2

iKOOLCORE R2 Max Review Proxmox VE Ubuntu 22.04

I’ve already checked out iKOOLCORE R2 Max hardware in the first part of the review with an unboxing and a teardown of the Intel N100 system with two 10GbE ports and two 2.5GbE ports. I’ve now had more time to test it with an OpenWrt fork, Proxmox VE, Ubuntu 24.04, and pfSense, so I’ll report my experience in the second and final part of the review. As a reminder, since I didn’t have any 10GbE gear so far, iKOOLCORE sent me two R2 Max devices, a fanless model and an actively-cooled model. I was told the fanless one was based on Intel N100 SoC, and the actively-cooled one was powered by an Intel Core i3-N305 CPU, but I ended up with two Intel N100 devices. The fanless model will be an OpenWrt 23.05 (QWRT) server, and the actively cooled variant be the device under test/client with Proxmox VE 8.3 server […]

How to use iperf3 in multi-thread mode for 10Gps+ Ethernet testing

With 10GbE becoming more widespread and often found in entry-level hardware, the CPU may become the bottleneck, so I’ll explain how to use iperf3 in multi-thread mode to fully saturate the 10GbE bandwidth even with a system based on a relatively low-end multi-core processor.

For this tutorial, I use two iKOOCORE R2 Max mini PCs with two 10GbE interfaces each and an Intel N100 quad-core processor running an OpenWrt fork (QWRT) and Proxmox VE (Debian) respectively. I will show how I can fully saturate the 10GbE interfaces using multithreading, but not with a typical iperf3 single-core test.

Raspberry Pi 500 review with Raspberry Pi Monitor and teardown

Raspberry Pi 500 review with Monitor Speaker

The Raspberry Pi 500 keyboard PC is just out along with the 15.6-inch Raspberry Pi Monitor and received samples from Raspberry Pi for review a few days ago. I’ve had time to play with both, so in this review, I’ll go through an unboxing of the kit I received and report my experience with both the keyboard PC and monitor. Unboxing I received two packages. The first one with the Raspberry Pi Monitor, and the second with a Raspberry Pi 500 (UK layout), a 27W USB-C power adapter, and a micro HDMI to HDMI cable. So not quite a full Raspberry Pi 500 Desktop Kit since there’s no mouse and beginner’s manual but close to it. Let’s start with the keyboard PC. The bottom side of the package has some specs and a logo for the keyboard layout, in this case “UK”. There’s only the keyboard PC in the package. […]

Orange Pi 5 Ultra SBC offers HDMI 2.1 output and HDMI 2.0 input

The Orange Pi 5 Ultra is a Rockchip RK3588 SBC that’s slightly larger than a business card and visually identical to the Orange Pi 5 Max introduced last August, but replacing one of the two HDMI 2.1 video outputs on the latter with an HDMI 2.0 input port. The new single board computer is still offered with up to 16GB LPDDR5, an eMMC flash module connector or soldered-on eMMC flash, an M.2 socket for an NVMe SSD, 2.5GbE and WiFi 6E networking, and four USB 3.0/2.0 ports. Orange Pi 5 Ultra specifications: SoC – Rockchip RK3588 CPU – Octa-core processor with 4x Cortex-A76 cores @ up to 2.4 GHz, 4x Cortex-A55 cores @ up to 1.8 GHz Arm Mali-G610 MP4 GPU with support for OpenGL ES1.1/2.0/3.2, OpenCL 2.2, and Vulkan 1.2 6 TOPS AI accelerator with support for INT4/INT8/INT16/FP16 mixed operation VPU – 8Kp60 H.265/VP9/AVS2 10-bit decoder, 8Kp30 H.264 decoder, […]

Barebone Intel Celeron 2955U or Pentium 3805U fanless industrial mini PC goes for $60 (Promo)

Low-cost Intel Celeron 2955U fanless mini PC

If you’re in need of a low-end, cheap x86 platform you’re in luck since XCY is selling the X46G industrial fanless mini PC powered by an Intel Celeron 2955U Haswell processor or a Pentium 3805U Broadwell CPU for just about $60 as a barebone system, or around $74 with 4GB of RAM, a 64GB SSD, and a WiFi module as part of a Black Friday 2024’s promotion. It’s even cheaper in some other shops, as we’ll see below. Both CPUs have been discontinued since 2021, and nobody should use those in a desktop system unless you are of the very patient type. However, if you want to run some lightweight Windows or Linux application(s), make use of RS232 ports for industrial control, set up a Full HD HTPC, configure a dual GbE server, or need to run FreeDOS or similar x86-only operating systems, those ultra-cheap Intel mini PCs might prove […]
