Local LLM on NVIDIA RTX 4070 Ti SUPER 16GB

Is the NVIDIA RTX 4070 Ti SUPER 16GB the right card for this?

16 GB is enough for the 7B-to-14B range with room for context, and not enough for 32B at Q4. That single fact decides most of what this card is for. 672 GB/s of GDDR6X sets the ceiling on tokens per second once a model does fit. At about $800 it costs roughly $50 per gigabyte of VRAM and pulls up to 285 W. Catalogue throughput class: Q4 7B: 35-50, Q4 13B: 22-30.

4 other cards here carry 16 GB, so all of them load the same weights and differ only in how fast they read them. At 672 GB/s this is not the quickest of that group, so its argument is price rather than speed.

A 2024 part sits in the middle of this guide's range: old enough that backend support has stopped moving and the community has written up the quirks, new enough that nothing treats it as legacy. That is the least risky place on the calendar to buy from if you want the setup to work the first time.

What the price gap buys

The cheapest 16 GB option in this guide is the NVIDIA RTX 4060 Ti 16GB at about $450. This card costs $350 more and reads memory 133% faster, which is roughly the gain in tokens per second. It buys no additional model: both load exactly the same weights, so the question is only whether you are waiting on the output.

At 2 years old this is still a current retail part, so the price above is a shop price rather than a listing price and stock is the usual constraint rather than condition. Buying new also means the 285 W figure is the number your power supply has to meet from day one.

Where the NVIDIA RTX 4070 Ti SUPER 16GB sits in this guide

Across the 20 cards catalogued here, the NVIDIA RTX 4070 Ti SUPER 16GB ranks 12th on memory bandwidth at 672 GB/s, 10th cheapest at about $800, and 16th on bandwidth per watt at 2.4 GB/s per watt. Those three positions, not the capacity figure, are what separate it from other 16 GB parts.

GDDR6X uses PAM4 signalling to push more bits per clock than plain GDDR6, which is where this card's 672 GB/s comes from. It also runs hot: the memory modules, not the core, are usually the first thing to throttle under a long generation run.

This is a CUDA card, which in practice means every local runner in our tool directory supports it first. Ollama and llama.cpp pick it up without configuration; vLLM and TensorRT-LLM target it specifically. Driver and CUDA toolkit versions are the usual source of trouble, not the card.

Which catalogue models fit on NVIDIA RTX 4070 Ti SUPER 16GB?

Of the 46 models in our catalogue with per-size memory figures, 32 have at least one size that fits in 16 GB at Q4_K_M with room for context. The largest of each are below, biggest first.

Model	Largest size that fits	Weights at Q4_K_M
GPT-OSS	20B	14 GB
StarCoder2	15B	10 GB
LLaVA	13B	10 GB
DeepSeek Coder V2	16B	10 GB
Qwen 2.5	14B	9 GB
Qwen 2.5-Coder	14B	9 GB
Qwen 3	14B	9 GB
DeepSeek R1	14B	9 GB

A further 24 smaller models also fit; see the model catalogue.

The next sizes up are out of reach without offloading: Mistral Small 24B at 15 GB, Magistral 24B at 15 GB, Devstral 24B at 15 GB.

Expected tokens per second on NVIDIA RTX 4070 Ti SUPER 16GB

Memory bandwidth, not compute, is the bottleneck for single-stream token generation. The NVIDIA RTX 4070 Ti SUPER 16GB's 672 GB/s puts the following ceiling on a batch of one at 2048 tokens of context.

Model	Quantization	Status	Approx tokens/sec
Llama 3.2 1B	Q4_K_M	Fits in VRAM	~121 tok/s
Llama 3.1 8B	Q4_K_M	Fits in VRAM	~40 tok/s
Llama 3.1 8B	Q8_0	Fits in VRAM	~30 tok/s
Mistral Nemo 12B	Q4_K_M	Fits in VRAM	~27 tok/s
Qwen 2.5 14B	Q4_K_M	Fits in VRAM	~24 tok/s
Qwen 3 32B	Q4_K_M	Needs CPU offload	~4 tok/s

These come from a bandwidth heuristic (tokens/sec ≈ bandwidth in GB/s × a per-model efficiency factor), not from a test rig in our office. Real numbers move with model architecture, batch size and KV-cache size. Treat them as an order of magnitude, and treat the "reported throughput class" row in the table above as the community-measured figure.
