Oddbean new post about login | logout The Pi 5 is at least 2x faster than the Pi 4 in every meaningful way: WiFi, microSD, USB bandwidth, CPU, GPU... though it still sticks with 1 Gbps Ethernet (but with PTP now!) https://files.mastodon.social/media_attachments/files/111/141/305/703/311/969/original/9876a1b3e20f05db.png https://files.mastodon.social/media_attachments/files/111/141/306/331/495/121/original/e84fc5d906b3558d.png https://files.mastodon.social/media_attachments/files/111/141/306/646/537/364/original/3d11b25afa0ce4e9.png
The board includes the first custom silicon to hit an official Raspberry Pi SBC, the RP1 chip, which is a 'southbridge' between the BCM2712 and the rest of the IO. It has many tricks up its sleeve—expect to hear more about them in the coming months! https://files.mastodon.social/media_attachments/files/111/141/311/547/639/021/original/7c1b99d7b6ad2c8a.jpeg
There are also new battery, fan, and UART connectors, as well as a new power button, exposing some very handy quality of life improvements. This is the first Pi that's really comfortable being your tiny PC. https://files.mastodon.social/media_attachments/files/111/141/312/650/042/117/original/910ed2ec8eea0636.jpeg https://files.mastodon.social/media_attachments/files/111/141/313/145/339/810/original/bf966a2d8eda2c03.jpeg https://files.mastodon.social/media_attachments/files/111/141/313/539/516/402/original/61800c274004a916.jpeg
There's also a new Active Cooler and case with improved airflow and a much quieter PWM fan. These are both huge upgrades over what came before, and allow the BCM2712 to run forever without throttling. https://files.mastodon.social/media_attachments/files/111/141/314/884/023/109/original/16702e600d650d8f.jpeg https://files.mastodon.social/media_attachments/files/111/141/315/180/331/151/original/078b88a31e115112.jpeg
I tested a TON of stuff on these boards, most especially the new PCI Express connector on the #RaspberryPi 5—check out my #Pi5 blog post for more on that! https://www.jeffgeerling.com/blog/2023/testing-pcie-on-raspberry-pi-5 https://files.mastodon.social/media_attachments/files/111/141/316/361/393/362/original/eb88bdafacd4a380.jpg
@3ddab33a That’s looking *very* thorough, with one exception: energy efficiency/power consumption are not covered 🤓😅 (That’s the first thing I want to know for 24/7 candidate devices.)
@66bd66f8 I do have a bit in the video, I didn't go in depth in the blog post (lack of time, ugh!). It's 1.8W idle with the official PSU. Sometimes more if you use a 3A PSU instead, which is counterintuitive... but what I measured.
@3ddab33a they pretty much included everything I've been asking for. This may be the perfect Pi!
@3ddab33a I’m unreasonably excited for the UART connector. I should be excited about PCIe! But no, giddy about an easy serial connection.
@e3b10963 lol "how do you tell a dev from a typical user" "show them a dedicated UART port and see how they react"
@3ddab33a Well, I do work with Ampere Altra servers at my day job. Pretty soon I’ll even be managing the projects to support next gen processors like Ampere Siryn, etc. So I’m wondering things like what level of SystemReady the rpi5 supports.
@e3b10963 I asked about this in May—they aren't (yet) interested in pursuing SR support. I have expressed my interest in them getting there, but it's not a market demand from the majority of customers at this time. It'd be so cool to have SR SBC though!
