So, going through Google (and even these forums) you get a ton of conflicting information
Person 1 - "You need x2 the host RAM as you do the GPUs RAM"
Person 2 - "You only need enough host RAM to run the OS"
Person 1 - "I notice a significant drop in performance if the GPUs use less than 4 PCIe lanes"
Person 2 - "You won't even saturate a single PCIe lane"
Person 1 - "Run balanced hardware"
Person 2 - "A cheap CPU is all you need"
It sounds like a fight between miners and people with more money than research; so here's my question. What data is transferred when brute-forcing and when using a dictionary attack as you run hashcat? I'll give a couple of examples here, but if anybody wants to go into a deep dive of this subject (or know of a website that does) I would appreciate that a ton.
Brute-force:
Do the GPUs talk to each other much, or report back to the processor much with information via the PCIe lanes?
Dictionary:
How fast are the GPU's ripping information from the storage drive? Is it enough to saturate 4 lanes of PCIe 4.0 that a newer NVMe uses?
Overall:
Where can hashcat start to bottleneck hardware?
