Yeah, I'm only interested in the "least bad" here. Taking usability, libre and performance into account. I don't think that even the Framework Laptop 13 RISC-V will be completely libre.

Thanks for input though!

Actually, it is not true from what I've learned. For example, Intel is about to push chipset/bios upgrades to boost the performance of the new Core Ultra 9 285k. And that kind of driver can at best be open source and in the upstream kernel or at worst closed source and only installed by some windows only bloatware.

Nice website! Thanks!

Having to use windows when upgrading firmware is very Linux unfriendly.

 

The talk is that the Core Ultra 9 285K works better with Linux than Windows. What's your experience? And how well does it work with Proton?

 

I'm looking into buying a new system and I wonder which of all the mainboard manufacturers you recommend for Linux in general and gaming in particular? Which ones have the best Linux driver support and which ones publish open source drivers? Are AMD or Intel chipsets preferred?

Also general best bang for the buck recommendations are appreciated!

And yes, I have googled this and I have some ideas, but I'm interested in what my fellow Lemmies think. And I also want this information to be here on Lemmy instead of Reddit or AI generated blogs. If you feel offended by this, you're totally free to not reply and also down vote this post.

Ditching the Linux kernel is probably a good idea. Or at least run your own fork. Which I expect that many state actors and large companies already do. Also, I suspect that we'll see more large public kernel forks sooner rather than later. Even sooner if Linus retires.

To be honest, I don't care that much for myself. Guess I wasn't completely honest in OP. I'm just a nobody who gladly exposes his soft parts in exchange for cheap and easy access cat videos and general dopamine. Rather I'm thinking about what strategies policy makers, companies, NGOs and the general public should consider, as we crash into even more exciting times.

Ah, I think I have a better understanding of the PCIe hardware protocol now. Feel a bit more confident regard a 2 x8 setup. Thanks.

Just for the record: my understanding is that the HW protocol performs a handshake which settles the number of lanes that will be used when establishing a link. And the PCIe standard is always backwards compatible, so things should work just fine even if I buy something that says PCIe 6.0 later. Or at least the lower layers of the protocol should be compatible. And as long bandwidth isn't an issue.

Your contribution was noise. Not an answer. Do better next time.

Maybe I should rephrase my question.

Are PCIe 5.0 or backwards compatible 6.0+ devices (GPUs), that say x16 (16 lanes) in their product specification, required by the PCIe standard to also support only 8 lanes? I.e. can the device transceiver decide to not connect if not all lanes are available at the protocol level? I'm not referring to slot size here.

The thing is that there are motherboards that have 2 PCIe 5.0 16x slots that are connected to the CPU (hopefully not false marketing). But the slots are downgraded to 8x if you connect two devices, since a AM5 CPUs only have 24 lanes.

I probably need to read the PCIe 5.0 standard document if I want to be sure.

I did Google and I didn't find an answer.

This is related to my previous question about AM5. Turns out 2 8x lane GPUs on AM5 might be an option after all.

So my question: Does a 16x lane PCIe GPU always support x8 lanes as well? (Like a Radeon RX 7900 XTX or something bigger and better from the future.)

Hello!

I'm looking into buying a system for running inference with small to medium size LLM models. I wonder, is there any AM5 CPU + Chipset combination that supports 2x PCIe 16x with all lanes connected directly to the CPU? From what I've gathered my understanding is that there is no such configuration because the Ryzen 7000/9000 only have 24 PCIe lanes at best. This means I have to go for a Threadripper configuration, which is much more expensive. (The ROCm mGPU documentation states that all lanes shall be connected directly to the CPU.)

It's possible that I can manage running two GPUs with 8x lanes, but it's for sure not optimal..

But the thing is, it is quite hard for me to navigate the AMD website and the websites of various motherboard producers. I might very well be wrong.

So again: Is there any AM5 CPU + chipset combination that supports 2x PCIe 16x with all lanes connected directly to the CPU?

It is clear that the signal to noise ratio of the WWW is getting worse. It's much harder to find good content when using a good old search engine. And if it's good it is usually hosted on Reddit or Stackexchange.

So remember, even if it's easy too Google something (well, it isn't nowadays), we want to create a fediverse of good content that helps people (I hope). So, it's always better to write a real answer if you have the time and energy. Please help boost the SNR and reverse the AI fueled information degradation loop.
