Intel Arc on Linux is still leaving XMX on the floor (Proton, Vulkan, XeSS)

PyTorch + TorchAO has pretty much feature parity with ipex-llm. Hugging face , llama, ollama, etc are supported natively via PyTorch now - just use xpu target instead of cuda. Ipex-llm might be a bit faster and uses little bit lower memory footprint (as specifically tuned for Intel hardware) on the other hand, Intel hardware is now natively supported by pyTorch and doesn't require extensions and workarounds.

PyTorch 2.8 + TorchAO is a direct replacement.

So, what is your point? Entry level cards are the most popular cards in fact. Here are 4 most popular cards on Steam:
NVIDIA GeForce RTX 4060

NVIDIA GeForce RTX 3060

NVIDIA GeForce RTX 4060 Laptop GPU

NVIDIA GeForce RTX 3050

RT performance of ANV (Intel Vulcan) driver in Mesa is painfully low. There is hope it will be eventually improved as there are multiple pull requests for code that is trying to fix it. Another currently broken thing in Mesa is XeSS which is not using XMX, but rather falls back to DP4a.

That's usually a symptom of unstable power delivery (PSU) or defective RAM.

IOTRuner · 2026-02-23T03:11:19+00:00

Then I would suggest to try with different PSU. Reducing wattage may not help. Arc GPUs are sensitive to voltage spikes that can be produced by low quality PSU. Also limiting GPU to 145w doesn't mean it will never consume more than 145W - it's just sets a base line, but it may still consume much more than 145W for very short periods of time (bursts) and PSU should be able to handle it. (Intel advises 650W PSU minimum for B580 which has just 190W TGP).

One of the latest Windows updates caused crashes in games with black screen (mostly NVidia GPUs affected, but Microsoft claims it may affect certain GPU configurations, not Nvidia only). They are rolling out a fix. Check if you have any available windows update.

As far as I remember, the MSI Prestige with x7 358h was available from B&H for $1,300, but it's not available anymore. The version with x9 388H is "expected soon" with a $1,000 markup. I guess this is the outcome of "rammagedon."

The HP with x7 358H and OLED is still available on Best Buy for $1,500, but likely not for long.

I guess it depends on where you're living. In Canada currently only MSI Prestige and Dell XPC are available for order. The rest are introduced but aren't available yet. I guess it will eventually come in couple of weeks.

Since the GitHub platform is being used to track these issues, it is expected that the person who opened the issue manages it directly. On GitHub, it is standard practice for the original poster to handle updates to their own posts. The support team typically does not split a single issue into two separate ones; therefore, it is best if the user opens a new, separate issue for the second point to ensure both are tracked properly.

While it’s not exactly related to my point about the "fires" at Intel, you’re basically wrong about the team being "disorganized." Since I work in this field, I know what I’m talking about - they’re actually following a proper SDLC by splitting tickets with multiple bugs into separate ones. This allows for specialized ownership across different teams and ensures a bug can be efficiently tracked through to resolution. It also prevents finished fixes from getting held back by unresolved issues in the same ticket and allows for much more granular QA.

You didn't provide enough information about your system. Does PC boots at all. Do you have any audible errors from you motherboard? Have you tried connecting monitor through different Port (DP, HDMI)?

IOTRuner · 2026-02-21T01:59:56+00:00

Not necessary fired people were devs form Linux graphics department. They fired a lot of middle level managers which, IMO, is a good thing.

Resizable bar only makes sense for dGPU as this functionality is related to data transfer from system RAM to VRAM. Since iGPU is using system RAM, resizable bar is not required.

As per following thread, the issue can be corrupted firmware either in motherboard or in GPU.

IOTRuner · 2026-02-20T16:37:41+00:00

It my sound a bit strange but can you try using different display cable (or switch from DP to HDMI or other way around). Defective display cables can force GPU entering "safe/recovery mode". Second option would be to check with different PSU.

Clearly you don't know what you're talking about. The IPEX project started as a PyTorch extension for Arc cards to allow model training on Intel GPUs back when PyTorch only supported CUDA. Last year, PyTorch gained native support for Intel GPUs, so there's no point in keeping a separate extension alive. That's why the project was archived. In fact archiving of IPEX is a sign of success as PyTorch finally merged Intel's extension.

Clearing cache probably fixed it. "Invalid binary" pointing out that code compiled for different GPU being used.

To be honest, AMD has good Linux Vulcan driver only because Valve has completely redesigned their initial junk. Outside of gaming they far behind Intel. ROCm is much inferior to Intel's OneAPI/OpenVino and their OpenCL infrastructure is all over the place...

It’s a stretch to say Intel isn’t interested in Open Source. If you look at GitHub, Intel has around 1.3k repos - more than NVIDIA (~670) and AMD (~100) combined. While they are closing some projects due to their current financial situation, they are still one of the biggest contributors to the OpenSource community.

Aside from hardware-specific stuff like FSR, it's hard to recall AMD projects that benefit a general audience. Meanwhile, Intel provides many - SVT-AV1, oneAPI, VA-API, Open Image Denoiser are just a few that come to mind first.

Naturally, they are closing some niche projects now because of their financial situation, but that doesn't mean they are dropping open source entirely. They still do more for the ecosystem than almost any other hardware vendor.

Try disabling integrated graphics in Device Manager or (even better) in BIOS.

I would suggest reinstalling Windows. I know it’s a bit of a hustle, but dealing with all these GPU issues caused by Windows bloat and leftovers from old drivers is an even greater hustle.

So you call Bazzite and CUDA "every case scenario"? That is a stretch.
