Intel Lunar Lake hybrid mobile processors to integrate on-chip LPDDR5X memory (MoP)

While Intel Meteor Lake mobile processors are yet to become available, we already have a leak that provides quite a lot of details about the next-generation Lunar Lake hybrid mobile processor family (LNL MX) with supports for 8W to 30W base power designs and 16GB or 32GB on-chip LPDDR5x memory (Memory-on-Package, or MoP) to deliver higher memory bandwidth at reduced footprint and power. Developed in collaboration with Microsoft, the new Lunar Lake processor will come with four P-cores and four low-power E-cores, a new generation NPU and GPU architecture for AI workloads, and improved power management for lower power consumption (40% scenario power reduction) and improved battery life. Four SKUs are currently planned with either 16GB or 32GB dual-channel LPDDR5X memory: Core 7 MS3 (+ MoP) – Octa-core “12M” processor with 4x P-cores, 4x E-Cores, 8-core Xe2-LPG GPU, and 6-tile (12K9M) NPU Core 5 MS1 (+MoP) – Octa-core “8M” processor […]

WeAct ESP32H2-N4 – A $6 Bluetooth 5.2 LE, Zigbee 3.0, and Thread development board

WeAct ESP32H2-N4 is a low-cost ESP32-H2 development board with Bluetooth 5.2 LE, Zigbee 3.0, and Thread connectivity with a design very similar to the one of Espressif Systems’ ESP32-H2-DevKitM-1 development board, but sold for just $5.70 plus shipping. The ESP32-H2 wireless microcontroller is basically the little brother of the ESP32-C6 without WiFi and aims at low-power nodes in short-range IoT networks. We have previously seen it in Espressif hardware like the aforementioned ESP32-H2-DevKitM-1 and the ESP Thread Border Router board combining ESP32-H2 & ESP32-S3 wireless chips, but so far not in third-party boards, and WeAct ESP32H2-N4 changes that. WeAct ESP32H2-N4 specifications: Wireless module – ESP32-H2-MINI-1 MCU – Espressif Systems ESP32-H2 32-bit RISC-V microcontroller at up to 96 MHz with 320 KB SRAM, 128 KB ROM, 4 KB LP memory, Bluetooth 5.2 LE/Mesh and 802.15.4 (Zigbee/Thread/Matter) radios. Storage – 4MB flash storage PCB antenna Dimensions – 13.2×16.6×2.4 mm USB – 2x […]

International Black Friday and Cyber Monday 2023 deals and coupon codes

We’ve been writing about international Black Friday and Cyber Monday deals and coupon codes since 2014, as US-centric promotions such as Amazon’s Black Friday and Cyber Monday deals are not always available to the international audience of CNX Software. So once again, we’ve searched at Black Friday and Cyber Monday 2023 international promotions and discount codes from specific manufacturers as well as popular online stores such as Aliexpress, Banggood, and others. Aliexpress Black Friday and Cyber Monday event Aliexpress will have a Black Friday (and Cyber Monday) event in 2023, but we have limited details at this time since it will only start on November 23, contrary to some of the other deals we’ll feature below which are already up and running. But the event will have two periods: Nov 20-22 PT – Warm Up event where users can find and add items to the cart before purchasing during the […]

GEEKOM A5 Review – Part 2: Windows 11 Pro tested on an AMD Ryzen 7 5800H Mini PC

After unboxing GEEKOM A5 mini PC, checking out the hardware, and booting the device in the first part of the review, we’ve now had time to further test the AMD Ryzen 7 5800H mini PC with Windows 11 Pro operating system. The boot-up is quite fast and generally speaking the device performs well for the various tasks we ran on the mini PC. So in the second part of the GEEKOM A5 review, we will provide an overview of the system information, test features, perform benchmarks, check heat dissipation under load, and measure the power consumption of the mini PC while running on Windows 11 Pro. Software Overview and Feature Testing Going to System->About in Windows settings, we can confirm that the GEEKOM A5 mini PC is equipped with an AMD Ryzen 7 5800H processor clocked at 3.20 GHz (base frequency) and 32GB of RAM, and runs Windows 11 Pro […]

Allwinner VPU gets open-source Linux driver for its H.264 hardware video encoder

Allwinner V3s open source Linux video encoding driver

Long-time readers of CNX Software may remember Bootlin’s crowdfunding campaign launched in 2018 to bring open-source Allwinner VPU drivers to take care of hardware video encoding and decoding in mainline Linux. They managed to raise enough funds (over 30,000 Euros) from small donors and several companies (Olimex, Pine64, Libre Computer, FriendlyELEC, and Orange Pi) to work on open-source VPU drivers for mainline Linux, but only for MPEG2, H264, and H265 decoding for in a range of Allwinner SoCs such as the A20 and H5, but not quite enough to cover the cost of H264 video encoding. Five years later, Bootlin took it upon themselves to complete the work without backing or support from Allwinner and have now released an open-source Linux-kernel based V4L2 driver to support the H.264 video encoder found in Allwinner V3, V3s, and S3 camera SoCs. The new driver builds upon earlier work by the company to […]
