Qwen3-14B at Q4\_K\_M needs about 11.3 GB, and the GeForce RTX 3070 Ti has 8.0 GB usable. That figure is 8 GB of VRAM on the spec sheet, of which 8.0 GB is usable for weights and cache, at 608 GB/s memory bandwidth. Alibaba’s 14B Qwen3\. It sits in the sweet spot for 12–16 GB cards that want more quality than an 8B. These are estimates from [our formula](https://whatcanirunai.vercel.app/method/), not measured benchmarks.

Try other sizes in the [VRAM calculator](https://whatcanirunai.vercel.app/vram-calculator/) or see the [context length guide](https://whatcanirunai.vercel.app/context-length/). ## What to do instead * Run [Qwen3-8B](https://whatcanirunai.vercel.app/can-i-run/qwen3-8b/rtx-3070-ti/) instead (6.7 GB at Q4). It is a different model, not a drop-in, but it does fit this machine. * To hold Qwen3-14B at Q4, you need about 11.3 GB. The [GeForce RTX 3060 12GB](https://whatcanirunai.vercel.app/can-i-run/qwen3-14b/rtx-3060-12gb/) has 12.0 GB usable ($329 list price). * Our estimate is only 3.3 GB over this machine’s usable memory, so a tighter quant or a shorter context may work in practice. We still mark it as a no under [the published formula](https://whatcanirunai.vercel.app/method/). * CPU offload can load the weights anyway, but it is slow. We do not publish an offload tokens/sec figure. * See the [best GPU for this model family](https://whatcanirunai.vercel.app/best-gpu-for/qwen3/) and the [Qwen3-14B model page](https://whatcanirunai.vercel.app/models/qwen3-14b/). ## Other hardware for Qwen3-14B * [Qwen3-14B on an RTX 3060 12GB](https://whatcanirunai.vercel.app/can-i-run/qwen3-14b/rtx-3060-12gb/)Tight * [Qwen3-14B on an RTX 3080](https://whatcanirunai.vercel.app/can-i-run/qwen3-14b/rtx-3080-10gb/)Won’t fit * [Qwen3-14B on an RTX 4060 Ti 16GB](https://whatcanirunai.vercel.app/can-i-run/qwen3-14b/rtx-4060-ti-16gb/)Fits * [Qwen3-14B on an RTX 4070 Ti Super](https://whatcanirunai.vercel.app/can-i-run/qwen3-14b/rtx-4070-ti-super/)Fits * [Qwen3-14B on an RTX 4090](https://whatcanirunai.vercel.app/can-i-run/qwen3-14b/rtx-4090/)Fits * [Qwen3-14B on an RTX 5070 Ti](https://whatcanirunai.vercel.app/can-i-run/qwen3-14b/rtx-5070-ti/)Fits ## Other models on an RTX 3070 Ti * [Qwen3-32B on an RTX 3070 Ti](https://whatcanirunai.vercel.app/can-i-run/qwen3-32b/rtx-3070-ti/)Won’t fit * [Qwen3-30B-A3B on an RTX 3070 Ti](https://whatcanirunai.vercel.app/can-i-run/qwen3-30b-a3b/rtx-3070-ti/)Won’t fit * [Qwen3.8-27B on an RTX 3070 Ti](https://whatcanirunai.vercel.app/can-i-run/qwen3.8-27b/rtx-3070-ti/)Won’t fit * [Gemma 3 27B on an RTX 3070 Ti](https://whatcanirunai.vercel.app/can-i-run/gemma-3-27b-it/rtx-3070-ti/)Won’t fit * [Gemma 4 31B on an RTX 3070 Ti](https://whatcanirunai.vercel.app/can-i-run/gemma-4-31b-it/rtx-3070-ti/)Won’t fit * [gpt-oss-20b on an RTX 3070 Ti](https://whatcanirunai.vercel.app/can-i-run/gpt-oss-20b/rtx-3070-ti/)Won’t fit ## Quick answers Can I run Qwen3-14B on an RTX 3070 Ti? No. Qwen3-14B at Q4\_K\_M needs about 11.3 GB, and the GeForce RTX 3070 Ti has 8.0 GB usable. How much VRAM does Qwen3-14B need? About 11.3 GB at Q4\_K\_M, 19.0 GB at Q8\_0 and 35.0 GB at FP16, estimated for a \~4k context. How fast is Qwen3-14B on an RTX 3070 Ti? We do not estimate tokens/sec when the model does not fit. CPU offload is possible but slow. What context length can I use? The weights already do not fit, so longer context is not the limiting factor. --- Agent guide: https://whatcanirunai.vercel.app/llms.txt · JSON API: https://whatcanirunai.vercel.app/developers/
