I just wish they had 2x5GbE like the Orion O6. i/o heavily matters for my compute nodes. I wonder if 802.3ad bonding can bring 5gbit/s

It says that it has four 10 Gb/s USB ports (2 Type A and 2 Type C). It is unknown whether the ports are independent, or some of them or all of them are connected to an internal hub. Even if they were connected to a single CPU port through an internal hub, if you used two 5 Gb/s USB Ethernet interfaces you would get close to full speed for them. Having 10 Gb/s USB instead of the so-called "5 Gb/s" USB (in reality 4 Gb…

They’re independent

I hope Linux support for these chips matures quickly. Qualcomm's laptop chips are the only serious competitor to Apple's M-series in single core performance and power efficiency. Intel and AMD are both far behind.

I hope not just Linux support for these chips matures - but that the rest of the fabless chip vendors get a leg up as well, because .. The world needs non-Apple/-Qualcomm variants of this hardware architecture, imho.

Pretty darn quick.

I want to be able to buy ARM boards like I'm buying ITX PC boards. I don't want a special build of Linux from the SBC OEM, I don't want weird bootloaders, firmware and other embedded-like stuff. I just want an ARM-based PC board for my desktop and server closet (so Ampere stuff is out of the picture unfortunately).

Qualcomm has been upstreaming kernel support for their chips recently, so I'm hopeful.

Seems like you could add that pretty easily via USB and/or M.2. Either should have the necessary bandwidth.

I would use the m.2 e keys for sata and x4 m key for nvme ssds. That only leaves pcie gen3 x2.

I want to run a distributed network storage (ceph)

Yeah, I want edk2 uefi and mainline linux support at least for most functions (dont care about npu for example)

I wonder how well a usb 10gbit ethernet adapter would work then

But I really apprecate your reply!

I'll definitely buy one for testing when they become available for reasonable prices <500EUR for 16gig memory

I have been tinkering with the Windows Dev Kit 2023 which shares the same SoC as this board. Linux support has been improving but with only third party kernel patches. GPU support has been okay but I have noticed oddities at higher resolutions. Speaking of, none of the display port options could provide 4K at 120Hz so maybe this is one area that the Q8B can prove to be more capable; it is supposed to have an HDMI 2.1 port and two DP 1.4 capable usb-c ports.

The O6 runs mainline pretty good, only hiccups I know of are gpu acceleration and the npu.
