We’re happy to share that DeepComputing’s DC-ROMA RISC-V Mainboard for Framework Laptop 13 is now in stock and shipping in the Framework Marketplace. This is very much a developer-focused board to help accelerate maturing the software ecosystem around RISC-V, so we recommend waiting for future RISC-V products if you’re looking for a consumer-ready experience. We shared more detail on the Mainboard in an earlier blog post and video, but as a quick summary, this is powered by a StarFive JH7110 processor that uses the open source RISC-V ISA. The team at DeepComputing designed it to drop directly into a Framework Laptop 13 chassis or Cooler Master Mainboard Case.

Testing to see if this community is still functioning.

I'm a software developer with a platform-independent stack (java / postgre / mysql / intellij / docker), I use a Linux distro. I have a workstation, but would like to be able to work away from home. Good battery life, small size, staying cool under load are the priorities; I don't need a lot of power. So I thought maybe I should try ARM?

My first idea was to get a [refurbished] MacBook Air and learn how to use MacOS, although I'd love to support something... less proprietary and more open. I've never used an ARM Linux distro or ARM laptops, and I'm not sure how good they are for my application.

What is your experience?

The new Slimbook Plasma 6 laptop is detailed on Slimbook.com and features an AMD Ryzen 7 8845HS SoC with integrated Radeon 780M graphics, a 2560 x 1600 display, an aluminum chassis, and non-soldered DDR5-5600 memory. There are two DDR5 slots allowing for up to 96GB of memory as well as two NVMe M.2 2280 slots. The laptop is equipped with a 68Wh battery.

Last time I needed to add rf to a desktop, Intel AX200 seemed like the chipset to get. But now there are various new standards and the BE200 apparently has issues with AMD systems? So is there something newish from Qualcomm or others that I should be aiming for or would I probably be better off just picking up an AX210?

Since the card might be kicking around a while I'm curious what has the best overall Linux support with as many significant 802.11 standards and Bluetooth codecs as possible for general future-proof-ness. Would also be nice if it had good support for AP mode as that's sometimes handy or I might repurpose it into a router at some point.

While AMD Ryzen AI 300 series laptops have begun appearing with Zen 5 CPU cores, to date the launched laptops have revolved around having either the integrated Radeon 890M RDNA3.5 graphics and/or NVIDIA GeForce discrete graphics. For those wanting a Linux-friendly laptop with Radeon discrete graphics for more gaming and GPU/compute potential, that still leaves the still very powerful Zen 4 laptop options. Bavarian Linux PC vendor TUXEDO Computers recently launched the Sirius 16 Gen 2 as a nice workstation/gaming laptop featuring the Ryzen 7 8845HS with Radeon RX 7600M XT discrete graphics.

...

On the plus side the Ryzen 7 8845HS / Zen 4 support on Linux is very mature at this point and runs without issues. TUXEDO OS continues to be based on Ubuntu 22.04 LTS right now and works great with this laptop. Other modern Linux distributions work great as well from this hardware. With the Ryzen AI 300 series, you need to be running a very recent Linux kernel and Mesa, have the most up-to-date Linux firmware files, and potentially be aware of workarounds such as Panel Self Refresh (PSR) disabling and few other caveats pointed out in my prior Ryzen AI 300 series Linux testing.

...

TUXEDO advertises the Sirius 16 Gen 2 as having up to 10 hours of battery life with minimum brightness, without WiFi and Bluetooth, and without the keyboard backlight while idling. This is accurate in those conditions but most will certainly run with WiFi enabled and a higher brightness level in which case it's around a six hour battery life.

...

When jumping straight to the geometric mean of the 147 benchmarks, the Ryzen 7 8845HS does pretty well competing with the Ryzen AI 9 HX 370 Zen 5 SoC found within the new ASUS Zenbook S16. The TUXEDO Sirius 16 Gen 2 was around 10% faster than the Framework 16 laptop with Ryzen 7 7840HS SoC.

But the big difference is the Ryzen 7 8845HS was consuming much more power to be competing with the Ryzen AI 9 HX 370. The Ryzen 7 8845HS SOC was consuming 60 Watts on average during benchmarking with a recorded peak of 100 Watts in the Sirius 16 Gen 2. Meanwhile the Ryzen AI 9 HX 370 was consuming 20 Watts on average with a recorded peak of 34 Watts.
