So couple updates for ARM based desktop systems. Project Volterra was teased a while back, and now Microsoft has launched it as a shipping product. Officially known as the Windows Dev Kit 2023, it looks like a hell of a beast. Quick rundown of the specs:

Qualcomm® Adreno™ GPU, Snapdragon™ 8cx Gen 3
32GB LPDDR4x RAM 
512GB NVMe Storage
2x USB-C USB3.2 Gen 2 
3x USB-A USB3.2 Gen 2 
Mini-Display Port (supporting HBR2) connecting to primary monitor  
Ethernet Port (RJ45) 
Wifi 6 and BT 5.1

It also comes preinstalled with a full ARM-native software toolchain to develop Windows apps for ARM. I bought a 3D printer this year, so my fun stuff budget has been totally blown, or else I would be all over this like white on rice. This is the Windows ARM desktop I've been waiting for.
A single HBR2-only DP seems annoyingly restrictive. HBR2 isn't a lot to work with for MST, so you're likely going to need to give up USB-C ports if you want to run multi-monitor, and it only has two of those as well.

Otherwise, yeah, looks pretty nice.
 
Longterm update on my Samsung Galaxy Book Go. I don't know why Celeron and Pentium still have a place in the market. Performance is pretty much equivalent to all Celeron computers I've ever tried, and I honestly can't tell when an application I'm running is 32 or 64 bit x86, or ARM. I think the only ARM apps I use are the ones from the Windows store and Edge, and even then, I don't think even all of them are. I might have downloaded an ARM app from a third party website from time to time, but I honestly couldn't tell you which ones based on performance.

Oh yeah, and battery life is unreal. It's way better than my iPad Mini 6. I've been a HUGE fan of the Mini over the years, having owned a 1st, 3rd, and 4th gen. This 6th gen is a huge let down in battery life though. Realistically only 6-8 hours, which is WAY too few for an iPad. It's usually closer to 6 hrs. What is this, an Acer laptop circa 2015? An iPad should be minimum 10 hours, regardless of size, IMHO. My Galaxy Book runs circles around it, and then goes for a half marathon attempt afterwards. I've never had such good battery life in a laptop form factor. I'm sure M1 and M2 Macs are even better, but those are at least 5x more expensive, and around 10x more processing power than I need. With far worse software compatibility on top of that.

So yeah, Celeron has no justification for its existence any more unless you have some mission critical application that MUST have guaranteed 100% x86 compatibility, and you need something low power. Intel should shut the product line down, and give the money back to the shareholders.

However, in other videos he's pointed out that Radxa has the typical ARM SBC vendor habit of not supporting further software development for the boards after they've shipped.

I'm hoping this one gets decent mainline Linux support. It's a powerful chip and Rockchip parts have become more prevalent in recent years.

Radxa hasn't really been doing a good job of communicating the rollout of these boards, though. Ameridroid's latest update e-mail admitted that Radxa was terrible at communicating and therefore they didn't really have any concrete updates about shipments. Supposedly Radxa is shipping boards direct but not communicating tracking numbers to anyone.

"Chipset" and "chiplet" aren't synonyms, Upton!

I think the only thing this is missing is an on-board 4-pin JST SH connector using the Qwiic/Stemma QT pinout, so you don't need a HAT or other adapter just to take advantage of the now super common I2C peripherals that use that connector.

They only announced the 4GB and 8GB versions, but the board shots suggest there are 2GB and 1GB versions as well. I wonder when those will be released, or if they're something considered during development but abandoned for production since anything with as much CPU and GPU power as the Pi5 would really want a minimum of 4GB anyway.

Neat!

I wonder if that RP1 southbridge includes some RP2040 PIO trickery?
They probably would have mentioned it if it did.

Watched a video on the Pi 5 this morning and the person (who recently toured the Pi factory so has contacts) claims it can support up to 16GBs

There's some nice little additions to the board:
  • PCIe connectivity (though I'm a bit surprised they stuck to PCIe2)
  • Real-time clock
  • Switchable camera/display connections
  • A proper power button
  • Performance closer to that of other SBCs out now
Things I feel they missed:
  • 16 GB RAM option
  • External WiFi antenna option
  • Native SATA (this is a maybe really, with SATA fading in favor of NVMe)
Curious as to when the updated Compute modules will be announced.

Also be interesting to see if they can actually keep these in stock for consumers, instead of diverting all their production to corporate partners.
