From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Why DDR6 though? It will be expensive at start and won't bring much to your workstation unless you are really memory perf bound.
There's 6 around already? 5 is not even really established yet, only for gaming rigs relevant so far.
How time flies, eh? I went searching for more info - https://www.techpowerup.com/339178/ddr6-memory-arrives-in-2027-with-8-800-17-600-mt-s-speeds It also mentions an architectural change to increase the speed further.
A few of my applications are bound by memory performance. My idea is that, because DDR standards are only published every 5 years or so, it will have better longevity before technical obsolescence. When in its life cycle, will a DDR platform become cheaper?
Edit: typo.
Not sure, but I assume a couple of years at least - it might be also affected by stupid external factors, like insane tariffs and such. Also it will take some time for DDR6 perf to go up - for both mobos and memory. So even at the start you might be still better off DDR5 and if you go with DDR6 you might need to replace mobo and memory to get better perf. That's my impression on hardware situation, I might be wrong, though.
What is your use case for threadripper, I'm curious? AFAIK it's not a good match for gaming at least. Or is it?
I mainly use my workstation for Image editing (raw development and VFX), 3d animation and video editing. Then there's occasional ML inference for image generation or text generation. And lastly, some video games.
About video games: the 1st gen threadripper platform gained a bad reputation for gaming thanks to windows. I used to use Windows for so long and once I switched to GNU Linux it was like I got a new CPU for free. The reason is, Windows doesn't know how to properly do multi-threading, adding to that, my 1st gen Threadripper is basically 4 CPU dies glued together and for low latency applications like games the performance on windows will be trash and oh boy, it was. But on GNU Linux its fine. But compared to all cores on one die, it will be worse for games, yes.
I was kinda guessing that images, video and such are your use case - yep, those might really benefit from a faster memory and plenty of cores. Not sure if it affect ML much since it'd be calculated on GPU. Thanks for info on gaming.
