MeLE Overclock4C is an ultrathin pocket-sized mini PC powered by an Intel Processor N95 CPU

Mele Overclock4C is an Intel Processor N95 Alder Lake-N mini PC with an ultrathin (21mm) design which, as its name implies, supports “overclocking”, although what it really means here is the ability to increase the PL1 and PL2 power limits in the BIOS/UEFI in order to increase performance without actually changing the top frequency of the processor… It’s the same idea and virtually the same design as the MeLE Overclock3C which boosts the TDP of the Celeron N5095 Jasper Lake processor up to 18W instead of the 15W default. Here the TDP of the Processor N95 is likely boosted up to 20 Watts (as per Intel Ark) delivering a 33% performance improvement over the Celeron N5095. The Overclock4C is available with 16GB or 32GB DDR4, a 256GB eMMC flash, and a 256GB SSD. MeLE Overclock4C specifications: SoC – Intel Processor N95 quad-core Alder Lake N-series processor @ up to 3.4 […]

MediaTek drops efficiency cores in Dimensity 9300 Cortex-X4/A720 mobile SoC

MediaTek Dimensity 9300 is a premium octa-core 5G mobile SoC with two clusters of four Cortex-X4 cores and four Cortex-A720 cores, but doing without any Cortex-A520 efficiency core, plus the latest Arm Mali-G720 GPU, and a MediaTek APU 790 neural processing unit (NPU) capable of support generative AI and large language models (LLM) with up to 33 billion parameters. Arm invented big.LITTLE and then DynamIQ technologies in order to mix cores with different power efficiency and performance characteristics in order to improve power consumption. Their latest launches included the Cortex-X4 premium core, Cortex-A720 performance/big core, and Cortex-A520 efficient/LITTLE core, but MediaTek decided to do without the Cortex-A520 in the Dimensity 9300 which strikes me as odd for a mobile SoC where power efficiency is important for a long battery life. MediaTek Dimensity 9300 specifications: Octa-core CPU with DynamIQ 4x Arm Cortex-X4 at up to 3.25GHz 4x Arm Cortex-A720 up to […]

EDATEC launches two fanless cases for the Raspberry Pi 5 SBC

In my review of the Raspberry Pi 5 SBC I noted performance was much improved over the Raspberry Pi 4 but that the board required active cooling with the official solutions (active cooler and case with fan) for optimal performance under load and there weren’t any official fanless cases for the latest Raspberry Pi single board computer. EDATEC aims to fill that gap with two fanless cases for the Raspberry Pi 5 SBC, namely the ED-Pi5Case-B with a low-profile, but closed design, and the ED-Pi5Case-O open case with two heatsinks placed on the top and bottom of the Raspberry Pi 5. Both fanless cases are made of aluminum (CNC milled), available in silver or black, and provide easy access to all ports and most interfaces of the Raspberry Pi 5 including the GPIO header, MIPI connectors, PCIe FPC connector, and PoE header. However, the closed enclosure blocks the battery and […]

Giveaway Week 2023 – TBS7901 mini PCIe DVB-S2X/S2 module

The second prize of Giveaway Week 2023 is a TBS7901 mini PCIe DVB-S2X/S2 module designed to be connected to a PC or board with a mini PCIe socket in order to watch, record, or broadcast free-to-air video received from a satellite dish. I received both M.2 and mPCIe DVB-S2X modules last August, but I haven’t had time to test any of those yet. So I’m keeping the M.2 module for my own testing once time permits and will be giving away the mini PCIe module to one of CNX Software readers. The module comes with a coaxial antenna cable, as well as a TBS-7901PW power board and SATA power cable since DVB-S/S2/S2X satellite TV requires 13V and 18V DC as well which will be outputted won’t the power board using the 12V from a PSU. You’ll probably need a Windows machine too since TBS provides Windows drivers for the TBS7901 […]

Giveaway Week 2023 – VOIPAC iMX8M industrial development kit

The 10th edition of CNX Software giveaway week is on! We’ll have seven items to give away this time around: six items that I will send myself from my review samples and one from a company that will offer one of its own IoT development kits… We’ll start this year’s giveaway week with the VOIPAC iMX8M industrial development kit equipped with an “iMX8M Industrial Pro” system-on-module powered by an NXP i.MX 8M quad-core Cortex-A53 processor, fitted with 2GB RAM, 16GB eMMC flash, and a WiFi and Bluetooth module. The VOIPAC iMX8M industrial development kit is quite a feature-rich development board whose main purpose is to evaluate the company’s system-on-module for integration into final products. I tested it last summer showing how to get started with the Yocto BSP by building the image from scratch, booting from the eMMC flash or a microSD card, and testing several features such as networking, […]

Raspberry Pi 5 review – Part 2: Raspberry Pi OS Bookworm, benchmarks, power consumption, and more

A few days ago I finally went through the Raspberry Pi 5 kit I received last September going through all the items and booting it with Raspberry Pi OS bookworm. I’ve now had time to perform more tests to check out the performance with benchmarks and test various features on the Raspberry Pi 5. So I’ll report my experience in the second part of the review and compare the Raspberry Pi 5 SBC to the Raspberry Pi 4 and some other Arm Linux SBCs.

System information in Raspberry Pi OS Bookworm

Last time around, I installed the Raspberry Pi 5 in its official case, but for most of the testing, I decided to go back to the bare board fitted with its active cooler since it’s the best cooling option as we’ll see further in the review.
