Can I Run Cogito v1 14B on NVIDIA GeForce RTX 4070?
Written by Jakub Rusinowski · Last updated July 12, 2026
Yes, but it's tight. Cogito v1 14B needs 10.9 GB at 8K context (8.5 GB weights + 2.4 GB KV cache/overhead) at Q4_K_M and the NVIDIA GeForce RTX 4070 has 12 GB, leaving about 1.1 GB of headroom, at roughly 45 tok/s (estimated) with room for up to 8K of context.

Cogito v1 14B on the NVIDIA GeForce RTX 4070: VRAM by quantization
| Quant | VRAM needed | Fits 12 GB? | Max context | Whole PC |
|---|---|---|---|---|
| F16 | 30.4 GB | ✗ No | — | — |
| Q8_0 | 17.3 GB | ✗ No | — | — |
| Q6_K | 13.9 GB | ✗ No | — | — |
| Q5_K_M | 12.3 GB | ✗ No | — | — |
| Q4_K_M | 10.9 GB | ✓ Yes | 8K | — |
| Q3_K_M | 8.4 GB | ✓ Yes | 16K | — |
| Q2_K | 7 GB | ✓ Yes | 32K | — |
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 12 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 4070: 8K 10.9 GB · 32K 15.7 GB ✗ · 128K 35 GB ✗. Past 32K it no longer fits 12 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Nothing to change — run it at Q4_K_M. If you want more capability, check whether the next size up also fits.
