Best Local AI Models for RTX 4070 Ti SUPER (16GB)
The RTX 4070 Ti SUPER packs 16GB GDDR6X and delivers 72 tokens per second for 8B models. A strong performer from the previous generation, offering enough VRAM for 14B models with solid throughput.
Quick answer
The best local LLM for the RTX 4070 Ti SUPER is Gemma 4 E4B (Q8) at ~73 tok/s on its 16GB VRAM. It uses ~7.5GB of VRAM; the RTX 4070 Ti SUPER handles up to 14B parameter models at Q4. A 14B model at Q4 runs at ~45 tok/s.
Sizing rule: a Q4 model needs about 0.6 GB of VRAM per billion parameters, and ModelFit budgets 90% of this card's 16GB for weights, context, and KV-cache. The per-size table below uses that same budget. Other strong fits: Qwen3.5 9B Instruct (Q8) (9B, ~10.7GB) and Qwen3 8B (Q8) (8B, ~8.1GB). Gemma 4 E4B (Q8) runs at an estimated 73 tok/s on this card. What it will not run: a 32B model does not fit in VRAM alone, so it spills to system RAM over PCIe and slows sharply.

Estimated Speed by Model Size
Fits in memoryCPU offload
ModelFit estimates, not measured benchmarks: anchored to an 8B-class Q4_K_M model at 16K context on the RTX 4070 Ti SUPER's 672 GB/s bandwidth, then scaled by model size. MoE rows scale by active parameters (decode reads only the active experts), so a 35B MoE runs far faster than a dense 32B. "CPU offload" sizes exceed the 16GB VRAM; dense models slow to a crawl there, MoE models degrade less because hot experts stay GPU-resident.
Context costs VRAM too. Gemma 4 E4B (Q8) loads ~7.5 GB of weights; at 16k context the KV cache adds ~2.0 GB (still fits the ~14 GB usable VRAM), and at 64k it adds ~8.0 GB (exceeds the budget, use a smaller quant or a q8_0 KV cache).
KV-cache figures assume an fp16 cache, the llama.cpp/Ollama default. Standard GQA models use a size-class estimate (8 KV heads x 128 head dim class); hybrid linear-attention models (Qwen3.5/3.6, Qwen3-Next) use the exact per-token cost from their published config, since only their sparse full-attention layers cache KV. A q8_0 KV cache roughly halves either figure. Estimates, not measurements.

RTX 4070 Ti SUPER VRAM for AI: What Actually Fits?
16GB GDDR6X at 672 GB/s positions this card between the 5060 Ti and 5070 Ti in bandwidth. It loads 14B Q4 models with room to spare and handles 7B models at 72 tok/s. The main drawback is pricing: it launched at $799 MSRP, but 2026 memory-shortage pricing has pushed street prices well past that, above the newer RTX 5070 Ti, which is actually faster. Best bought used, where prices sit closer to the original MSRP.

RTX 4070 Ti SUPER FAQ: Common Questions
How much VRAM does the RTX 4070 Ti SUPER have for LLMs?
The RTX 4070 Ti SUPER has 16GB GDDR6X VRAM with 672 GB/s bandwidth. About 15.5GB usable for model loading. Fits 14B models at Q4 and all 7B-9B models comfortably.
What size LLM can I run on an RTX 4070 Ti SUPER?
Up to 14B parameter models at Q4 quantization. Same model capacity as other 16GB cards. Speed on 8B models is an estimated 72 tok/s (14B around 45), faster than the 4060 Ti but slower than the newer 5070 Ti.
Is the RTX 4070 Ti SUPER still worth buying for AI in 2026?
At current street pricing, well above its $799 launch MSRP due to the 2026 memory shortage, no. The RTX 5070 Ti costs less and is 21% faster. However, used 4070 Ti SUPERs at $600-700 still offer good value: you get 16GB VRAM and ~72 tok/s on 8B models at a reasonable price.
RTX 4070 Ti SUPER vs RTX 5070 Ti for local AI?
The RTX 5070 Ti is faster (an estimated 87 vs 72 tok/s on 8B), cheaper, and uses GDDR7. The 5070 Ti wins on every metric for AI workloads. The only reason to buy the 4070 Ti SUPER is availability or used pricing.
How fast is a 27B-class model on the RTX 4070 Ti SUPER?
The RTX 4070 Ti SUPER's 16GB of VRAM cannot fit a 32B model comfortably. The largest size class it fits is 20B MoE (3.6B active), at an estimated 68 tok/s. The largest individual model in the catalog that fits is LFM2 24B-A2B Instruct (24B).
