Dear Urist, please advise on Dwarfputer 2022
« on: May 13, 2022, 02:11:39 pm »
Dear Urist,

I'm in the lucky position of getting a new dwarfputer soon! So I've been wondering...

Intel has fast DDR5 RAM but generates heat and eats a lot of power. AMD, on the other hand, runs colder and with less power, but has slower RAM. AMD also just released a shining new processor called "Ryzen 7 5800 X3D", with a veritable giant 96MB L3 cache. I'm also not quite sure, whether should I go for 32GB or 64GB RAM. Does an old, large embark need so much?

What would be you choice for large embark area, speed and efficiency?

Sincerely,
the Expedition Leader

You'd need to work hard for a fort to require more than 4 GB of RAM. My 5x5 embarks in "smaller" 33x33 worlds with 500 years of history and 50k world population only need about 2GB of RAM.

I opine that the most important bottleneck for FPS is the effective transfer frequency of the RAM-to-CPU bus, and would opine that the CPU's memory cache is nice but that DF overwhelms it. My opinions may need seasoning.

There is something to be said about, if the stakes are as high, maybe reconsider your certitudes. One has to be aggressively allistic to feel entitled to be able to trust. But it won't happen to me, my bit doesn't count etc etc... Just saying, after my recent experiences I couldn't trust the public if I wanted to. People got their risk assessment neurons rotten and replaced with game theory. Folks walk around like fat turkeys taunting the world to slaughter them.

For reference, though in Russian.
