It has been over four years since the release of the Raspberry Pi 4, and in that time a lot has changed in the maker board and single-board computer landscape. For the Raspberry Pi Foundation there were struggles with worldwide demand and production capacity brought on by the global pandemic starting in 2020, and plenty of new competitors came to the scene to offer ready to order alternatives to the venerable RPi 4. Today however the production woes have been assuaged and a new generation of Raspberry Pi is here; the Raspberry Pi 5.

Raspberry Pi 5 is being announced in advance of availability unlike every prior RPi device launch. Pre-orders are open with many of the listed Approved Resellers on RPi's website starting today but unit shipments aren't expected until near the end of October 2023. As part of this pre-order scheme, RPi Foundation is withholding pre-orders from bulk customers and will be dealing in single-unit sales for individuals until at least the end of the year, as well as running some promotions with The MagPi and HackSpace magazines to give priority access to their subscribers. Genuinely nice to see, considering how hard it was to obtain a Pi 4 for the average Joe over the last couple years. The two announced prices for the RPi 5 are $60 USD for the 4 GB variant, and $80 USD for the 8 GB variant; or about $5 USD more than current reseller pricing on comparable configurations of the Raspberry Pi 4.

Considering all the buzz around WiFi 7, there weren't many live demos at Computex, but Realtek had a demo running in its suite at the show. Realtek will offer both client and router/AP solutions, with their client product which goes under the RTL8922AE model name, coming in M.2 2230 and 1620 formats, where the latter is a solder down module. To simulate a real world scenario, Realtek was running a second radio to cause some additional interference, but the RTL8922AE test setup was still capable of delivering between 1,750 and 1,950 Mbps, which is almost twice as fast as WiFi 6, using a similar 2x2 antenna setup. This was obviously over a fairly short distance, so the question is how well WiFi 7 will work over longer distances.

The RTL8922AE has a claimed maximum sync speed of 2800 Mbps when connected to the 5 GHz and 6 GHz bands simultaneously and combining the bandwidth of both bands. However, it is limited to a 160 MHz channel bandwidth, whereas WiFi 7 can go up to a 320 MHz wide channel, but it's unclear if competing first gen clients will support this. The RTL8922AE also incorporates support for Bluetooth 5.4 and is as far as we're aware one of the first WiFi chips to support the upcoming standard that mostly focuses on improving BLE Audio and Auracast support. The RTL8922AE should launch sometime in the fourth quarter this year to Realtek's customers, so it might not appear on the market until early 2024.

Samsung Electronics today announced the global launch of its full 2023 Smart Monitor lineup. The new M8, M7 and M5 Smart Monitors (Model Name: M80C, M70C, M50C) from Samsung enable users to tailor their monitors to their unique styles and needs, as they watch, play and work.
