Quick verdict
NVIDIA RTX 4070 Ti SUPER wins for local AI inference. It has 4 GB more VRAM and 33.3% more memory bandwidth, runs 46 models natively (vs 31), and exclusively fits 15 models the other cannot.
Analysis
NVIDIA's January 2024 Super refresh replaced the RTX 4070 Ti at the exact same $799 launch price the original card carried a year earlier, but with a real spec bump: 4GB more VRAM and a wider memory bus, not just higher clocks. For anyone deciding between the two today, mostly on the secondhand market since NVIDIA discontinued the plain 4070 Ti, the gap in local LLM capability is much larger than the identical price tag suggests.
The RTX 4070 Ti SUPER moved off the RTX 4070 Ti's AD104 die onto the larger AD103 die shared with the RTX 4080, gaining 4GB of GDDR6X (12GB to 16GB) and a wider 256-bit bus (672 GB/s, up from 504 GB/s, a 33.3% bandwidth increase) alongside 768 more CUDA cores (8,448 vs 7,680). For local LLM inference, the VRAM jump matters more than the bandwidth: this site's calculator can't even complete a fair quant-for-quant comparison on Qwen 3.6 27B, since the plain RTX 4070 Ti's 12GB can't hold the model at any quantization and falls back to a CPU-offloaded Q8_0 build at 1.3 tok/s, while the Ti SUPER's 16GB holds it natively at Q3_K_M, a meaningfully higher-quality build, at 37.4 tok/s. GPT-OSS 20B, a model OpenAI explicitly sized for a 16GB card, shows the same pattern: 17.4 tok/s offloaded on the RTX 4070 Ti versus 166.1 tok/s natively on the Ti SUPER (a mixture-of-experts model streams only its active experts from system RAM, so it degrades far more gracefully than a dense one). For models that already fit both cards' 12GB, like Llama 3.1 8B at Q8_0, the Ti SUPER still decodes faster (55.2 vs 42.5 tok/s, a 29.9% gain against the 33.3% bandwidth difference) purely from its bandwidth edge.
Bottom line: For local LLM use specifically, the RTX 4070 Ti SUPER is the clearly better card at an identical launch price: more VRAM that changes which models fit at all, plus meaningfully faster decode on everything both cards can run. The plain RTX 4070 Ti only makes sense today at a steep secondhand discount below the Ti SUPER's used-market price, and even then only for workloads that stay comfortably inside 12GB.

Which should you choose?
- • You need to run larger models (>12 GB VRAM)
- • Faster token generation is the priority
- • You want the newer architecture and longer driver support lifecycle
- • Price or availability decides it: NVIDIA RTX 4070 Ti has no VRAM, bandwidth or backend advantage over NVIDIA RTX 4070 Ti SUPER
