I realize this has not much to do with CPU choice per se, but I'm still gonna leave this recommendation here for people who like to build PCs to get stuff done with :) Since I've been able to afford it and the market has had them available, I've been buying desktop systems with proper ECC support. I've been chasing flimsy but very annoying stability problems (some, of course, due to overclocking during my younger yea…

The big problem with ECC for me is that the sticks are so much more expensive. You'd expect ECC UDIMMs to have a price premium of just over 12.5% (because there are 9 chips instead of 8), but it's usually at least 100%. I don't mind paying reasonable premium for ECC, but paying double is too hard to swallow.

You would think that competition would naturally regulate the price down, but it seems like we are dealing with some sort of a cartel that regulators have not caught up with yet.

I feel like both Intel and AMD are not doing great in the desktop CPU stability department. I made a machine with a Ryzen 9900X a while back and it had the issue that it would freeze when idling. A few years before I had a 5950X that would regularly crash under load (luckily it was a prebuilt, so it was ultimately fixed). When you do not have a bunch of components ready to swap out it is also really hard to debug the…

Have had three systems (two 5800x, one 3600x) that reboots/freezes due to WHEA errors. Started after about 3years problem free. One of the 5800xs so frequently it was trashed.

I wonder if it's related to the main board... Are you running X or B series chipsets? I've found that less is more when it comes to stability. Vendors always add features to justify the $200-300 price of X series.

I have always run B series because I've never needed the overclocking or additional peripherals. In my server builds I usually disable peripherals in the UEFI like Bluetooth and audio as well.

Nothing, I'm making this up, except it's been confirmed by pretty much all desktop Zen users: https://www.reddit.com/r/Amd/comments/1brs42g/amd_please_tac... I don't bloody care that AMD CPUs seem to be more power efficient than Intel's. For most people their CPUs are completely idle most of the time and Zen CPUs on average idle at 25W or MORE. Many Zen 4 and Zen 5 owners report that their desktop CPUs idle at 40W or…

I can't confirm the 40W, my Ryzen 9 7900 (non-X) consumes 1W to 3W at idle on Windows 10.

Please post a HWiNFO64 screenshot.

I have reasons to believe you're making this up.

Not a single user has seen such low idle power consumption for desktop Zen AMD CPUs.

I wonder why the idle power is so high(55 watts), I have measured a beelink mini PC with an 8 core Zen4 when idle, and it was 10 watts.

It's the 3D cache, as I wrote in my other response. It has to be powered on at all times, so it affects even the idle power usage.

It has little to nothing to do with the 3D cache.

The IOD (die) is extremely inefficient for all desktop Zen CPUs as it never truly idles.

Sure, it's reported by the Radeon Software, but I'll check HWiNFO64 soon and post a screenshot.

For the past 30 odd years I've hand picked and built a desktop PC (which also acts as a home server) pretty much every year, selling the "old" one each time. I really enjoy it as a hobby and for the benefits of understanding and optimizing a system at the parts level. Even though there is a lot of nonsense created by all the choices and marketing, I really prefer the parts approach, and am happy with Linux so a Mac isn't very appealing. A perfectly designed PC can do tasks very well with optimized parts and at a much better price.

But I just can't bring myself to upgrade this year. I dabble in local AI, where it's clear fast memory is important, but the PC approach is just not keeping up without going to "workstation" or "server" parts that cost too much.

There are glimmers of hope with MR-DIMMs CU-DIMM, and other approaches, but really boards and CPUs need to support more memory channels. Intel has a small advantage over AMD, but it's nothing compared to the memory speed of a Mac Pro or higher. "Strix Halo" offers some hope with four memory channel support, but it's meant for notebooks so isn't really expandable (which would enable à la carte hybrid AI; fast GPUs with reasonably fast shared system RAM).

I wish I could fast forward to a better time, but it's likely fully integrated systems will dominate if the size and relatively weak performance for some tasks makes the parts industry pointless. It is a glaring deficiency in the x86 parts concept and will result in PC parts being more and more niche, exotic and inaccessible.

You take backups and do checksums for the valuable data. For the rest, who cares...

Let's say you corrupted one bit in a blender asset 200 revisions ago and it was unnoticeable and still upgraded through five blender upgrades, but now on the sixth upgrade it fails with a corruption error and doesn't upgrade.

Without knowing how to fix that error you've lost 200 revisions of work. You can go back and find which revision had the problem, go before that, and upgrade it to the latest blender, but all your 200 revisions were made on other versions that you can't backport.

Could it be that that some cores are constantly being waked up by something?

I mention that since you seem to be on Windows, which itself has a hard time to just shut up, but that is also easily paired with bad drivers, stupid software and bad peripherals.

I think most parts are geared towards gaming these days. When I've needed a server, I went for multi-CPU setups with older, cheaper CPUs.

That being said, for AI, HEDT is the obvious answer. Back in the day, it was much more affordable with my 9980XE only costing $2,000.

I just built a Threadripper 9980 system with 192GB of RAM and good lord it was expensive. I will actually benefit from it though and the company paid for it.

That being said, there is a glaring gap between "consumer" hardware meant for gaming and "workstation" hardware meant for real performance.

Have you looked into a 9960 Threadripper build? The CPU isn't TOO expensive, although the memory will be. But you'll get a significantly faster and better machine than something like a 9950X.

I also think besides the new Threadripper chips, there isn't much new out this year anyways to warrant upgrading.
