You're comparing RAM amounts to other RAM amounts without considering requirements. 24GB is more than (most) current games would ever require, but is considered a uncomfortably-constrictive minimum for most industrial work.

Traditional CPU-bound physics/simulation models have typically wanted all the RAM they could get; the more RAM the more accurate the model. The same is true for AI models.

I can max out 24GB just using spreadsheets and databases, let alone my 3D work or anything computational.
