Can I Run Falcon 3 on NVIDIA GeForce RTX 3080 (10GB)?
Written by Jakub Rusinowski · Last updated July 12, 2026
Yes, comfortably — Falcon 3 10B Instruct at Q4_K_M needs 8.4 GB at 8K context (6.2 GB weights + 2.2 GB KV cache/overhead), leaving ~1.6 GB of the NVIDIA GeForce RTX 3080 (10GB)'s 10 GB, at ~59 tok/s (est.), with room for up to 16K context.

Falcon 3 10B Instruct on the NVIDIA GeForce RTX 3080 (10GB): VRAM by quantization

Assumes an 8K-token context with an f16 KV cache. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 10 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the NVIDIA GeForce RTX 3080 (10GB): 8K 8.4 GB · 32K 12.4 GB ✗. Past 32K it no longer fits 10 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? Falcon 3 10B Instruct on 16 GB of system RAM, CPU only: runs.
