Can the RTX 4090 Run Gemma 2 9B?

Runs

Yes. Gemma 2 9B at Q4_K_M is a 5.8 GB download (Hugging Face file listing for bartowski/gemma-2-9b-it-GGUF), and the RTX 4090 has 24 GB of VRAM, leaving about 18.2 GB for the KV cache and runtime. No published speed measurement for this pair passes SpecPicks' sanity checks yet, so no tokens-per-second figure is quoted.

More about this pair

How much VRAM does Gemma 2 9B need?

The Q4_K_M file is 5.8 GB. Add roughly 1.5 GB for the runtime and an ~8K-token context, so about 7.3 GB of VRAM holds it comfortably. Longer contexts grow the KV cache and need more.

What is the fastest Gemma 2 9B can generate on the RTX 4090?

Generation reads every weight once per token, so the RTX 4090's 1008 GB/s of memory bandwidth divided by the 5.8 GB file sets a ceiling near 175 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.
