System76 built the fastest Windows Arm PC

System76 built their first workstation-class Arm PC, the Thelio Astra, and it's marketed for streamlined autonomous vehicle development.

But I'm not an automotive developer, just someone who enjoys Linux, Arm, and computing. So I was excited to spend a few weeks (which turned into a few months) testing the latest Ampere-based computer to come to market.

I initially ran my gauntlet of tests under Ubuntu 24.04 (the OS this workstation ships with), but after discovering System76 dropped in ASRock Rack's TPM 2.0 module, I switched tracks and installed Windows 11—which went without a hitch!

Documenting an 1115 ft radio tower climb

Some broadcast engineering tasks are a bit too daunting for me to consider. Climbing the massive towers that power radio and TV stations is one of them!

Recently, local engineer Aaron Cox had the perfect set of conditions for a drone flight to capture some of that risk, as the weather and timing of an antenna inspection lined up perfectly with his schedule.

I'll summarize a bit of what we talked about in today's Geerling Engineering video, but if you want to watch that directly, it's embedded below:

The Pi 500 is much faster, but lacks M.2

Raspberry Pi this morning launched the Pi 500 and a new 15.6" Pi Monitor, for $90 and $100, respectively.

They're also selling a Pi 500 Kit, complete with a Power Supply, Mouse, and micro HDMI to HDMI cable, for $120. This is the first time Raspberry Pi is selling a complete package, where every part of a desktop computer could be Pi-branded—and makes me wonder if uniting all these parts into one could result in an eventual Pi Laptop...

Before we get too deep, no, the Pi 500 does not include a built-in M.2 slot. Sort-of.

AmpereOne: Cores are the new MHz

Cores are the new megahertz, at least for enterprise servers. We've gone quickly from 32, to 64, to 80, to 128, and now to 192-cores on a single CPU socket!

AmpereOne A192-32X open

Amazon built Graviton 4, Google built Axiom, but if you want your own massive Arm server, Ampere's the only game in town. And fastest Arm CPU in the world is inside the box pictured above.

It has 192 custom Arm cores running at 3.2 Gigahertz, and in some benchmarks, it stays in the ring with AMD's fastest EPYC chip, the 9965 "Turin Dense", which also has 192 cores.

High-core-count servers are the cutting edge in datacenters, and they're so insane, most software doesn't even know how to handle it. btop has to go full screen on the CPU graph just to fit all the cores:

Raspberry Pi CM5 is 2-3x faster, drop-in upgrade (mostly)

Raspberry Pi Compute Module 5

The Raspberry Pi Compute Module 5 is smaller than a credit card, and I already have it gaming in 4K with an eGPU, running a Kubernetes cluster, and I even upgraded my NEC Commercial display from a CM4 to CM5, just swapping the Compute Modules!

The Compute Module 4 was hard to get for years. It launched right after the COVID supply chain crisis, leading to insane scalper pricing.

It was so useful, though, that Raspberry Pi sold every unit they made, and they're inside everything: from commercial 3D printers, to TVs, to IP KVM cards.

LLMs accelerated with eGPU on a Raspberry Pi 5

After a long journey getting AMD graphics cards working on the Raspberry Pi 5, we finally have a stable patch for the amdgpu Linux kernel driver, and it works on AMD RX 400, 500, 6000, and (current-generation) 7000-series GPUs.

With that, we also have stable Vulkan graphics and compute API support.

When I wrote about getting a Radeon Pro W7700 running on the Pi, I also mentioned AMD is not planning on supporting Arm with their ROCm GPU acceleration framework. At least not anytime soon.

Luckily, the Vulkan SDK can be used in its place, and in some cases even outperforms ROCm—especially on consumer cards where ROCm isn't even supported on x86!

AMD Radeon PRO W7700 running on Raspberry Pi

Raspberry Pi 5 with AMD Radeon PRO W7700 graphics card

After years of work among a bunch of people in the Pi community (special callout to Coreforge!), we finally have multiple generations of AMD graphics cards working on the Raspberry Pi 5.

We recently got Polaris-era GPUs working (like the RX460), but in the past month we've gotten 6000 and 7000-series GPUs up and running. And many parts of the driver work at full performance—well, as much as can be had on the Raspberry Pi's single PCIe Gen 3 lane (8 GT/sec)!

I've been testing tons of modern AAA games, like Doom Eternal and Crysis Remastered, and can get 10-15 fps at 4K with Ray Tracing on, or 15-20 fps at 4K. Dropping down to 1080p is not enough to overcome the Pi's CPU bottleneck—only at resolutions under 720p does the Pi's CPU and the single PCIe lane not seem to get in the way quite as much.

Popular Rockchip SBC distro in limbo after maintainer burns out

Recently Joshua Riek posted he's dropping off from GitHub. If you haven't heard of him, he's one of the few reasons working with Linux on Rockchip SBCs is so much easier today than it was just a few years ago.

His Ubuntu Rockchip distribution is built for Ubuntu 22 and 24, and they've been maybe the most popular and stable way to run Ubuntu on Rockchip devices.

So popular, in fact, that manufacturers who use Rockchip, like Turing Pi, build their own official images on top of Joshua's.

XKCD Dependencies

Now, if you're reminded of XKCD #2347, yeah, I am too.

Home Assistant and CarPlay with the Pi Touch Display 2

After a decade, Raspberry Pi finally upgraded their official Touch Display from 480p to 720p, while keeping the price and overall aesthetic the same.

Raspberry Pi Touch Display 2 - Home Assistant Dashboard

I've had early access to the Touch Display 2, and have been testing it in a variety of scenarios. Generally, Linux touchscreen support isn't wonderful. And Pi OS, being a fairly customized UI focused on simple use cases, is not quite to a usable state if you go touchscreen-only, considering I had trouble getting the onscreen keyboard to work in Chromium half the time, and it would overlay things I was typing even in fully-supported apps like Terminal.
