Why do people use M for Megabytes?
The way I understand it JEDEC had standardized KB/MB/GB being multiple-of-2-based in memory specs prior to the IEC standardising KiB/MiB/GiB for the same. As a result it kind of just stuck in the space since the idea of multiple-of-10 cache is a bit silly anyways so there is no risk for confusion.
Have you noticed how AMD and Intel just do tiny steps, sometimes even not worth writing about when it comes to innovation? It's always either AMD matching the new Intel CPU of other way around - it's never about eg. completely crushing Intel. This is the problem of late stage capitalism, where both companies are owned by the same large investment funds and they use their power to ensure neither company could eat too…

When they manually forced it onto the CCD with 3D-Vcache, they saw a 100% speedup: " As we can see in our Factorio benchmark, we saw massive gains of over 100% when forcing the Ryzen 9 7950X3D to use the CCD with the 3D V-Cache as opposed to letting AMD's PPM Provisioning and 3D V-Cache Optimizer drivers do their thing automatically. "
So presumably a bug that can be fixed by either AMD updating their optimizer, Factorio updating to work better with it, or both?

I just disable PBO on my 3900X - you are 100% correct that an extra 5% performance is not worth the extra 30% power draw/heat.
This is the same as AMD "Eco Mode"?
Test yourself, but I am definitely going to leave it enabled.

Or just buy the X3D that have cache on each CCD instead of half of them.
There is currently no consumer model with 2 CCDs and X3D on both of them.

Is there a point to going beyond 60 updates/s in Factorio? Because if not the system seems to be doing the correct thing and using less power. I hope AMD isn’t causing higher power usage for all users just to game some benchmarks!

Wow. I don't needed such CPU now, but if I needed a low-noise/silent but performant PC I would definitely look at this one.

Silly question: what constrains cache sizes? What prevents just making them bigger and bigger?
If you do a full reticle chip and use most of it for memory you can get about 1GB of SRAM. But that would also be extremely expensive.

If it's a problem for Factorio it's also a problem for others, so definitely something to fix on the AMD side.
