Can the RTX 3090 Run Llama 3.2 1B?

Runs

Yes. Llama 3.2 1B at Q4_K_M is a 0.8 GB download (Hugging Face file listing for bartowski/Llama-3.2-1B-Instruct-GGUF), and the RTX 3090 has 24 GB of VRAM, leaving about 23.2 GB for the KV cache and runtime. Published runs put generation at a median of 267 tokens per second across 1 cited measurement. Fastest cited run: LocalScore.ai.

More about this pair

How much VRAM does Llama 3.2 1B need?

The Q4_K_M file is 0.8 GB. Add roughly 1.5 GB for the runtime and an ~8K-token context, so about 2.3 GB of VRAM holds it comfortably. Longer contexts grow the KV cache and need more.

What is the fastest Llama 3.2 1B can generate on the RTX 3090?

Generation reads every weight once per token, so the RTX 3090's 936 GB/s of memory bandwidth divided by the 0.8 GB file sets a ceiling near 1156 tokens per second. Real runs land below it; SpecPicks rejects any published figure above it.

How the checks work

The fit is the Q4_K_M file size against the card's VRAM, with 1.5 GB kept for the runtime and an ~8K context. A published run counts only if the pair fits, the run is Q4-class, its source does not call it an estimate, it is under the bandwidth ceiling above, and it is not one figure pasted across many cards.
