I've been testing a LOT of functionality on Nvidia and AMD GPUs (Intel a little less, but we'll get back to that) on the Raspberry Pi. You can get Nvidia graphics cards working on RK3588 and Pi 5/CM5/500+ now, thanks to mariobalanica's patch which I mentioned in a brief video.
Today I've been testing Jellyfin hardware transcoding performance, and I have a blog post up talking about the progress. It was easier than I expected, and the 2nd picture shows two streams (4K and 1080p) being transcoded in realtime on a CM5 with my 4070 Ti.
Hello there, Raspberry Pi CM0. EDAtec sent this to me from China. Unfortunately you can't get these anywhere else! It's basically a Pi Zero 2 W, but in SoM form. And it has castellated edges so it can be pick 'n placed right onto PCBs.
We had about two years of good availability at MSRP, but prices on almost everything computer-related that has DRAM or flash memory inside is likely to follow the Pi's footsteps in the coming months :(
We were instructed to make angry sysadmin faces in the second picture. Apparently that's not possible lol! It was great seeing Patrick of @ServeTheHomeVideo and Wendell of @Level1Techs at #SC25!
32 GB GPU on a Pi CM5; You don't even have to recompile Linux anymore! Testing underway, but check out my latest blog post on www.jeffgeerling.com for a quick how-to.
Still testing the new DeepComputing DC-ROMA Mainboard II, with 8 SiFive P550 cores, Imagination GPU, and separate NPU chip, with 32 GB of shared RAM. The way it works is... interesting.
Stay tuned for a video. This one might take a little longer than usual.
How much radiation can a Raspberry Pi handle in space? I asked Ian Charnas, the chief engineer for Mark Rober's Crunchlabs, and he shared a ton of great data on testing the CM4 while prepping for their SatGus cubesat launch!
Short answer, it reset (soft reboot) on average every 39.3 Rads on a cyclotron at UC Davis, and was killed (couldn't reboot anymore) at 57.8 kRad in the gamma radiation testing lab at University of Maryland!
There are three cubesats in this photo, one meant for local learning, built around an ESP32 microcontroller. Another meant for eventual space flight (but this one was a test mule for one that just went to the stratosphere!), and a third meant for... being *hacked*? Hopefully I'll be able to wrap up my testing so I can get this video out soon.
Because there's a fourth sat, not pictured, that's going to space soon... more to come :)
(Also, all credit goes to the people who build these things—lest you think I had anything to do with them, I did not, I just love space, love tiny computers, and love the integration of the two!)
After over two years, the Compute Blades I ordered on Kickstarter finally arrived. Doing and re-doing things (and re-doing them again) ten times is fun! I wish Ansible had a physical hardware installation plugin.

Raspberry Pi prices are back on the rise due to AI companies driving up DRAM prices.
One more domino to fall to the AI bubble inflation pressures: www.raspberrypi.com/news/1gb-raspberry-pi-5-now-av…
