SECO launches Mediatek Genio 510 and 700 SMARC SoMs built for industrial and edge AI applications

SECO SOM SMARC Genio510 module with MediaTek Genio510

SECO SOM-SMARC-Genio500 and SOM-SMARC-Genio700 are two new SMARC system-on-modules products powered by MediaTek Genio 510 and 700 Cortex-A78/A55 series SoCs. These industrial modules are designed for high power efficiency and offer reduced energy consumption even during intensive edge AI workloads, and are suitable for retail touchscreens, intelligent industrial sensors, advanced conferencing systems, and dynamic digital signage. Both modules feature up to 8GB LPDDR4 memory, 64GB eMMC flash, two Ethernet interfaces via RGMII and USB, an optional M.2 slot for a Wi-Fi/Bluetooth module, and camera inputs. We’ve previously considered Via’s offerings with the same MediaTek Genio 700 application processor: a SMARC module, a single-board computer, and a fully embedded system. The IBase ISR500 is another option featuring the Mediatek Genio 510 or Genio 700. SECO SOM-SMARC-Genio700 & SOM-SMARC-Genio510 specifications: SoC (one or the other) SOM-SMARC-Genio700 – MediaTek Genio 700 (MT8390) CPU – Octa-core processor with 2x Cortex-A78 cores @ up to […]

GEEKOM GT1 Mega review with Ubuntu 24.10 – Part 3: Linux on an Intel Core Ultra 9 185H “Meteor Lake” mini PC

GEEKOM GT1 Mega Ubuntu 24.10 Linux review

We’ve already had a look at GEEKOM GT1 Mega’s hardware with an unboxing and a teardown before following up with a thorough review of the Intel Core 9 Ultra 185H mini PC with Windows 11 Pro. After being interrupted by some Raspberry Pi reviews, I finally had the time to test the GEEKOM GT1 Mega with Ubuntu 24.10 to check out how well (or not) it works with a recent Linux distribution. I’ve tested the features of the Meteor Lake mini PC in Linux, ran some benchmarks, evaluated storage and network performance, played 4K and 8K videos on YouTube at various frame rates, went through a stress test to check its thermal design, and finally measured the mini PC’s fan noise and power consumption. Ubuntu 24.10 installation I would usually review mini PCs with the latest Ubuntu LTS version which would currently be Ubuntu 24.04.1. However, since the Intel Core […]

Vulkan 1.4 3D graphics and compute API released

The Khronos Group has just announced the release of Vulkan 1.4 cross-platform 3D graphics and compute API. The new release makes some of the optional extensions and features mandatory, adds streaming transfers, and supports 8K rendering on up to eight targets. Minimum hardware limits have also been increased including at least seven maxBoundDescriptorSets and eight maxColorAttachments. Vulkan 1.4 highlights: Streaming Transfers: new implementation requirements to ensure applications can stream large quantities of data to a device while simultaneously rendering at full performance. Previously optional extensions and features critical to emerging high-performance applications are now mandatory in Vulkan 1.4, ensuring availability across multiple platforms. These include push descriptors, dynamic rendering local reads, and scalar block layouts. Maintenance extensions up to and including VK_KHR_maintenance6 are now part of the core Vulkan 1.4 specification. 8K rendering with up to eight separate render targets is now guaranteed to be supported, along with several other […]

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 […]

GEEKOM Mini Air12 Lite Review – Part 3: Ubuntu 24.04 on a low-cost mini PC

GEEKOM Mini Air12 Lite Ubuntu 24.04 review

We have already checked the hardware of the GEEKOM Mini Air12 Lite mini PC in the first part of the review, before testing the low-cost Intel Processor N100 mini PC with its 8GB RAM and 256GB SATA SSD running Windows 11 Pro in detail in the second part. We’ve now had time to test the GEEKOM Mini Air12 Lite with Ubuntu 24.04 in the third and final part of the review. We’ll test the features in Linux, run some benchmarks, evaluate storage and network performance, play some 4K and 8K videos in YouTube playback, perform a stress test to check its thermal design, and finally measure the mini PC’s fan noise and power consumption. We’ll also compare the results in Linux to the earlier GEEKOM Mini Air12 mini PC with the same CPU, but better specs and a higher price. A challenging Windows 11 / Ubuntu 24.04.1 dual boot installation […]

Mitigating a DoS attack with GoAccess and Cloudflare

In this off-topic post, I’m going to discuss some behind-the-scenes “fun” that may happen when managing the web server used to host the CNX Software website. From time to time, the server becomes unreachable, but I can still access its console, and notice a very high CPU load (over 100) on a VPS with four cores, while the CPU load is typically 0.5 to 2 under normal circumstances. That’s usually due to a DoS (denial of service), DDoS (distributed denial of service), or some bug I can’t identify. An easy way to solve this issue is to log in to Cloudflare and set the “Under Attack Mode” to on. It will show all visitors a JavaScript challenge the first time they visit the website, and the CPU usage typically drops back to normal level within a minute or so. That means I can access my website and so do regular […]
