First summary of the season, which seems to be starting a bit slow. Let's see if it picks up some pace:

Core i9-12900KF

Someone brought us a Core i9-12900KF the other day, which is the first DDR5 platform we've received. It takes the gold medal in single-thread and the bronze in multi-thread.

DDR5 continues to be refined

DDR5 memory continues to improve its performance. At the moment, Intel's controller is capable of reaching 7000MT/s. In addition, JEDEC has improved the memory latencies to 5600MHz.

Using a Raspberry Pi to build a Bluetooth speaker

Someone has created a guide to send audio over Bluetooth to a Raspberry Pi. By connecting the board to self-amplified speakers or a Hi-Fi system, you can create Bluetooth speakers.

USB-C with different protocols

The idea of using USB-C to move different protocols is becoming a problem when it comes to knowing what type of port our PC really has and what type of devices we can connect. In this post, they explain what ports and what protocols there are.

The first stable version of OpenWrt

Although OpenWrt has been with us for almost 20 years and has been stable and functional for a long time, the first officially stable version of the firmware intended for network hardware has now appeared.

NASA chooses RISC-V as architecture

NASA has decided to use the RISC-V architecture for its missions. Specifically, they will use the X280 implementation from SiFive with 12 cores.

Ryzen 7 5700G

Someone has brought us a Zen 3 Cezanne with 8 cores. The Ryzen 7 5700G runs at 4.6GHz and is ranked 34th in the overall ranking.
