Test Intel Arc Pro B50 dGPU

[geerlingguy]

Intel just delivered an Intel Arc Pro B50 with 16GB of VRAM, and I'd like to see if it's as simple to get running as the A750 and B580 I've been testing recently.

I will follow the same bringup I've done with the other Arc cards with the Xe driver, for example:

• Intel Arc A750
• Intel Arc B580

This card having 16GB of VRAM, it reports Small BAR device, though it seems the BAR is still 8GB. I don't recall the A750 or B580 outputting Small BAR here. (In fact, I looked up the logs and no, they do not complain). I guess the 16GB card would like a larger BAR, but at least there are no other errors there!

vkmark gets a normal score (around 14,000), but there are a lot of artifacts, or bits of the scene that are just black/un-rendered, for example, right out of the gate:

glmark2-es2-wayland is perfect, however, scoring 5945. There are no artifacts and all scenes render:

[geerlingguy]

The full system idles around 15W (Pi 500+ and B50 with power supplies accounted for as well), and maxes out at 78.7W, which means the card probably does top out right around 70W total power draw (during GravityMark scene renders).

Running some AI benchmarks in geerlingguy/ai-benchmarks#27

Due to VRAM issues, I'm guessing this card will fare similarly as the B580, with some corruption on larger models.

[geerlingguy]

One nice thing about this card: it's exceptionally quiet. I only heard a little coil whine on a few scenes, and the fan only ramps up to maximum after sustained load (and even there, it's maybe 40 dB and not unpleasant).

[geerlingguy]

I am trying to get SYCL working for GPU compute (supposedly it's faster than Vulkan for Intel GPUs), following llama.cpp's guide, but it looks like it's not seeing the B50 at least:

$ sudo apt install clinfo
Preparing to unpack .../clinfo_3.0.25.02.14-1_arm64.deb ...
Unpacking clinfo (3.0.25.02.14-1) ...
Setting up clinfo (3.0.25.02.14-1) ...
...

$ sudo clinfo -l

Nothing is output, so it's not seeing a GPU I guess?

Edit: Intel also pointed me to some setup instructions for Ubuntu, see Installing Client GPUs

[geerlingguy]

After switching around a few other GPUs and setting VRAM to 8GB for medium BAR, I'm getting:

$ vulkaninfo --summary
'DISPLAY' environment variable not set... skipping surface info
vulkaninfo: ../src/intel/dev/intel_hwconfig.c:143: process_hwconfig_table: Assertion `next <= end' failed.
Aborted

Also the same when I try running labwc-pi.

If I disable my resize-bar service (sudo systemctl disable resize-bar.service), take out the manual XE bar size option in cmdline.txt, and reboot, then manually sudo modprobe xe, and that works...

Though I've also run into a fun issue with the M.2 adapter working its way out due to tension on the OCuLink cable; because the cable is oriented towards the right side of the Pi 500 now, I can't screw down the M.2 adapter, so I just have some pressure on it from the keyboard to try to hold the card in place. That certainly isn't the best for signal integrity :D

I may switch gears back to a Pi 5 or CM5 on IO board for more testing, as it will give a more stable physical platform.

Pair all that with the Minisforum DEG1 dock, which I had trouble with in the past—I've taken to powering it off and back on to make sure things are reset properly on it.
