RTX 4060 Ti 16GB vs RTX 4070 Ti SUPER
Both hold the same 16 GB, so the split is speed: the RTX 4070 Ti SUPER has about 2.3× the memory bandwidth. Decode speed on a memory-bound workload scales with bandwidth, so that ratio is the number that matters once the model fits at all.
Specs side by side
| Spec | RTX 4060 Ti 16GB | RTX 4070 Ti SUPER |
|---|---|---|
| VRAM | 16 GB | 16 GB |
| Memory bandwidth | 288 GB/s | 672 GB/s |
| TDP | 165 W | 285 W |
| Models that fit (Q4_K_M) | 374 of 506 | 374 of 506 |
What the extra VRAM actually buys
Nothing, in model-fit terms: every model in our catalog that fits the RTX 4070 Ti SUPER at Q4_K_M also fits the RTX 4060 Ti 16GB. The extra capacity goes to longer context, bigger batches and higher-precision quantization — not to a larger model tier.
Largest model each can run
At Q4_K_M the biggest fit in our catalog is Mistral Small 24B (3.1) Instruct (15.0 GB) on the RTX 4060 Ti 16GB, and Mistral Small 24B (3.1) Instruct (15.0 GB) on the RTX 4070 Ti SUPER. Both figures are weights plus runtime overhead; KV cache for your context is extra.
Power and running cost
At 8 hours a day the RTX 4060 Ti 16GB draws about 40 kWh a month against 68 kWh for the RTX 4070 Ti SUPER — a difference of 29 kWh. Multiply by your own tariff; we do not assume one. Board TDP is the rated figure, not measured draw.
FAQ
RTX 4060 Ti 16GB vs RTX 4070 Ti SUPER: which should I buy for local AI?
The RTX 4070 Ti SUPER fits 374 of the 506 models in our catalog at Q4_K_M against 374 for the RTX 4060 Ti 16GB, and has about 2.3× the memory bandwidth, which is what sets decode speed once a model fits. If the models you run already fit the RTX 4060 Ti 16GB, the extra spend buys context length and speed, not a new model tier.
Is the RTX 4070 Ti SUPER faster than the RTX 4060 Ti 16GB?
On memory-bound decoding, yes — roughly 2.3× the throughput, since token generation scales with memory bandwidth (672 GB/s vs 288 GB/s). This is an upper bound from bandwidth alone, not a measured benchmark.
How much more VRAM does the RTX 4070 Ti SUPER have?
Neither has more — both carry 16 GB. No model in our catalog needs the difference at Q4_K_M.
