Practical notes
A strong local AI value when power, cooling, and used-market risk are acceptable.
The 24GB tier changes model options more than small benchmark deltas do.
Source-backed model fit
RTX 3090 24GB planning boundary
Planning lane
24GB VRAM 14B–32B planning lane
Treat 14B–32B as a planning range for short-to-moderate contexts; actual fit depends on quantization, runtime allocation and workload.
Planning band: 20–24 GB. It is not a measured requirement.
Memory boundary
24GB VRAM is a planning boundary, shared with the platform or runtime where applicable; it is not a measured compatibility guarantee.
Uncertainty to keep visible
Official device facts support this planning lane, but do not measure runtime allocation, throughput, model quality, or long-context fit.
