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 […]

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

Raspberry Pi 5 Review Raspberry Pi OS Bookworm

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.

Review of Arylic H50 wireless stereo amplifier with TIDAL Music

We’ve recently completed the review of the Arylic BP50 Bluetooth preamplifier where we tested the audio quality while streaming audio from the TIDAL Music app. But RAKOIT also sent us the Arylic H50 wireless stereo amplifier for review, and we’ll report on our experience with that device today using the TIDAL Music app again. The H50 is an audio streaming player with a digital-to-analog (DAC) converter chip and a built-in power amplifier. It supports wireless networks such as WiFi and Bluetooth and plenty of wired connections namely analog RCA line In, analog RCA phono In, digital optical in, Subwoofer out, RJ45 LAN port, HDMI ARC, USB Type-A Host, and USB Type-C. To use the Arylic H50, simply connect the output signal cable to stereo speakers (passive speaker) with 50 watts of output power on each side, allowing you to stream music from various services through the 4STREAM app or Spotify, […]

Nordic nRF54L15 Cortex-M33 wireless MCU halves Rx power consumption over nRF52 chips

Nordic Semiconductor has recently unveiled the 128 MHz nRF54L15 Cortex-M33 multi-protocol wireless microcontroller, the first from the nRF54L Series, and the second from the wider nRF54 family after the more powerful 320 MHz nRF54H20 dual-core Cortex-M33 MCU was introduced last Spring. While the nRF54H20 was designed to enable new types of IoT devices with a leap in performance and lots of resources with up to 2 MB flash and 1MB SRAM, the new nRF54L15 aims to be an upgrade to the nRF52 series with twice the performance and much better power efficiency, with for instance, half the Rx power consumption over its predecessor. Nordic Semi nRF54L15 key features and specifications: CPU Arm Cortex-M33 @ up to 128 MHz with up to 1.5 MB Flash + 256 KB SRAM RISC-V coprocessor for “software-defined peripheral” Wireless Bluetooth 5.4 LE with direction-finding, Bluetooth mesh, etc… Ready for future Bluetooth releases 802.15.4 radio for […]

LILYGO T-ETH-Lite – An ESP32-S3 board with Ethernet, optional PoE support

LILYGO T-ETH-Lite ESP32-S3 is a new ESP32-S3 WiFi and Bluetooth development board with a low-profile Ethernet RJ45 connector using a WIZnet W5500 Ethernet controller, supporting PoE with an extra shield, and also equipped with a microSD card socket and expansion I/Os. ESP32-based development boards with Ethernet have been around for years including LILYGO’s own “TTGO T-Lite W5500“, but so far we haven’t many based on the more recent ESP32-S3 microcontroller except for the SB Components’ ESPi board that we covered last April. But LILYGO T-ETH-Lite ESP32-S3 adds another cost-effective board with Ethernet. LILYGO T-ETH-Lite ESP32-S3 specifications: Wireless module ESP32-S3-WROOM-1 MCU – ESP32-S3 dual-core LX7 microprocessor @ up to 240 MHz with Vector extension for machine learning Memory – 8MB PSRAM Storage – 16MB SPI flash Connectivity – WiFi 4 and Bluetooth 5 with LE/Mesh PCB antenna Storage – MicroSD card slot Connectivity 802.11 b/g/n WiFi 4 up to 150 Mbps and […]
