# Can I Run HunyuanVideo 13B on RTX 5060 Ti 16GB? GGUF & TeaCache Sizing

> **Direct Compatibility Verdict**: Yes, the 16GB NVIDIA GeForce RTX 5060 Ti can run Tencent HunyuanVideo 13B locally using GGUF `Q4_K_M` (or Blackwell FP8 with block-swap), consuming 14.60 GB VRAM (+1.40 GB safety margin). Because HunyuanVideo pairs a 13B dual-stream/single-stream DiT with dual text encoders (an 8B LLaVA-Llama-3 MLLM plus CLIP-Large), sequential text-encoder offloading, tiled 3D VAE decoding, and TeaCache (`2.1x` speedup) are mandatory to fit inside the 16GB GDDR7 buffer.

## Key Memory Physics
| Metric | Value |
|---|---|
| Target AI Model | Tencent HunyuanVideo 13B DiT |
| Target Hardware | NVIDIA GeForce RTX 5060 Ti (16GB) |
| Q4_K_M VRAM Required | 14.60 GB |
| Available Headroom | +1.40 GB |
| Estimated Generation Speed | ~185s / 61f clip |

## Hardware Physics & Bottleneck Analysis
Tencent HunyuanVideo 13B combines 20 dual-stream MMDiT blocks and 40 single-stream transformer blocks with a heavyweight multimodal text encoder (`llava-llama-3-8b-v1_1` taking ~8.5 GB in FP8) and `CLIP-ViT-L/14`, followed by a 3D CausalConv VAE. On a 16GB RTX 5060 Ti, attempting to keep the 8B LLaVA text encoder and 13B DiT resident simultaneously triggers an immediate allocation overflow. However, ComfyUI's GGUF loader (`hunyuan-video-t2v-720p-Q4_K_M.gguf`, `~7.9 GB` weights) stages the 8B LLaVA encoder in VRAM first, computes prompt embeddings, purges the encoder back to system DDR5 RAM, and then streams the 13B quantized DiT across the RTX 5060 Ti's 448 GB/s GDDR7 bus alongside a 4.2 GB spatio-temporal activation workspace.

## Tier 1 Free Software Optimization ($0)
Use `ComfyUI-GGUF` with `hunyuan-video-t2v-720p-Q4_K_M.gguf`, wire `HunyuanVideo TeaCache` (`rel_l1_thresh = 0.16` for a `2.1x` speedup), and always route latents through `VAE Decode (Tiled)` with `tile_size = 256` so 544x960 or 720p 61-frame renders never exceed 14.6 GB VRAM.
