# NVIDIA RTX 5060 Ti (16GB) vs RTX 4060 Ti (16GB) for Local LLMs & ComfyUI

> **Direct Hardware Verdict**: While both cards offer an identical 16GB VRAM buffer on a 128-bit bus, the Blackwell RTX 5060 Ti 16GB replaces slow 18 Gbps GDDR6 with 28 Gbps GDDR7 memory—boosting external memory bandwidth by +55.6% (from 288 GB/s up to 448 GB/s). In local LLM inference, that bandwidth leap translates directly into 55% faster token decoding on Qwen 2.5 14B (31 vs 20 tok/s) and OpenAI gpt-oss 20B (85 vs 54 tok/s), while 5th-Gen Blackwell hardware FP4 Tensor Cores accelerate ComfyUI FLUX and HunyuanVideo workflows.

## Contender Specifications
| Metric | NVIDIA GeForce RTX 5060 Ti (16GB) | NVIDIA GeForce RTX 4060 Ti (16GB) |
|---|---|---|
| VRAM Capacity | 16 GB GDDR7 | 16 GB GDDR6 |
| Memory Bandwidth | 128-bit (448 GB/s) | 128-bit (288 GB/s) |
| Typical Price | $429 – $479 (New) | $449 – $499 (Retail / Used) |
| Estimated Throughput | ~31 tok/s (14B Q4) / ~85 tok/s (20B MoE) | ~20 tok/s (14B Q4) / ~54 tok/s (20B MoE) |

## Comparative Model Compatibility Matrix
| Model & Quantization | VRAM Demand | NVIDIA GeForce RTX 5060 Ti | NVIDIA GeForce RTX 4060 Ti |
|---|---|---|---|
| OpenAI gpt-oss 20B MoE (Q4_K_M) | 14.0 GB | Runs Comfortably (~85 tok/s) | Runs Comfortably (~54 tok/s) |
| Qwen 2.5 14B Instruct (Q4_K_M) | 10.9 GB | Runs Comfortably (~31 tok/s) | Runs Comfortably (~20 tok/s) |
| Tencent HunyuanVideo 13B (Q4_K_M) | 14.6 GB | Tight Fit (+1.4GB, FP8/FP4) | Tight Fit (+1.4GB, Slow) |
| FLUX.1 [dev] NF4 / FP4 | 12.0 GB | Runs Comfortably (+4.0GB) | Runs Comfortably (+4.0GB) |


## Silicon Architecture & Thermal Analysis
The Ada Lovelace AD106-based RTX 4060 Ti 16GB was notorious among local AI builders: despite having 16GB of clamshell GDDR6, its 128-bit memory controller topped out at 288 GB/s—slower than even the older $280 RTX 3060 12GB (360 GB/s). NVIDIA's GB206 die on the RTX 5060 Ti 16GB keeps the compact 180W 128-bit board footprint but pairs it with PAM3-signaling 28 Gbps GDDR7 modules to hit 448 GB/s. Furthermore, GB206 introduces 5th-Generation Tensor Cores with native microscaling FP4 (`NVFP4`/`MXFP4`) execution and PCIe 5.0 x8 host connectivity, doubling ComfyUI diffusion step throughput when running quantized FP4/FP8 DiT checkpoints like FLUX.1 [dev] and Wan 2.1.

## Tier 1 Free Software Optimization ($0)
If you already own an RTX 4060 Ti 16GB and feel bottlenecked by its 288 GB/s bus on dense 14B models, switch to sparse Mixture-of-Experts models like `OpenAI gpt-oss-20b` (`14.01 GB` total, only 3.6B active per token) to jump from 20 tok/s to 54 tok/s immediately.
