Daily Tech News 28 September 2023

Top Story

Now that production has finally caught up with demand and the Raspberry Pi 4 is actually available to buy again they've announced the Raspberry Pi 5. (Tom's Hardware)

The BCM2711 CPU in the Pi 4 has been replaced with a BCM2712. Which doesn't tell you much, but they've gone from a quad Arm A72 at 1.5GHz to a quad Arm A76 at 2.4GHz, which should be about twice as fast.

The 4GB model will be $60 (up from $55), and the 8GB model $80 (up from $75).

I just got a Pi 400 - the model built in to a keyboard - but they haven't announced a Pi 500 as yet so I can live with that.

The Pi 5 also has a single lane of PCIe 2, so you can add an M.2 SSD with a suitable adaptor. It will only run at around 400MBps, but will still be better than the current micro SD cards.

Tech News

A new design for small desalination systems could produce tap water that is cheaper than tap water, or possibly vice-versa. (MIT)

It's a passive solar-powered system, which is to say it works from the heat of the Sun rather than photovoltaic cells.

It's not remarkable - we've had such systems for decades - except for the fact that it apparently just keeps working once you set it up, without any maintenance.
Minisforum's new tablet is coming early in 2024 with a 14" 2560x1600 screen, a pressure-sensitive pen, the Four Essential Keys - which I have never seen on a tablet PC keyboard before - and a Ryzen 8000 CPU. (Liliputing)

Ryzen 8000 will bring Zen 5 cores with major performance improvements, but that doesn't mean that this Ryzen 8000 CPU will be Zen 5. Ryzen 7000 models variously have Zen 4, Zen 4c, Zen 3, and even Zen 2 cores.

It's a mess.

The laptop looks good though.
Hey, I died twice: Seagate drives are reaching 800 percent failure rates. (WCCFTech)

Annual failure rates.

They only had one drive of a particular model, and it failed after six weeks.

Which isn't great, but doesn't rewrite the laws of mathematics either.
Is Russia in the room with us right now? Twitter is leading the disinformation race in the EU say the kind of people who use the term "disinformation" unironically. (The Register)

"Russia", they added. "Russia, Russia, Russia."
