Can I Run Cogito v1 70B on NVIDIA GeForce RTX 4070 Ti Super?
Written by Jakub Rusinowski · Last updated July 12, 2026
No. Cogito v1 70B needs 45.7 GB at 8K context (42.3 GB weights + 3.4 GB KV cache/overhead) at Q4_K_M and the NVIDIA GeForce RTX 4070 Ti Super has only 16 GB. No quantization we publish closes a gap that size.

Cogito v1 70B on the NVIDIA GeForce RTX 4070 Ti Super: 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 16 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 Ti Super: 8K 45.7 GB ✗ · 32K 53.8 GB ✗ · 128K 86 GB ✗. Past 8K it no longer fits 16 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Either step down to a smaller size in this family, or move to a NVIDIA RTX 6000 Ada Generation (48 GB), the card with the least memory we track that holds it.
No compatible GPU? Cogito v1 on 8 GB of system RAM, CPU only: runs.
