Can the GeForce RTX 5060 Ti 16GB run Stable Diffusion XL 1.0?
Stable Diffusion XL 1.0 runs locally on an 8 GB GPU at Q4, which needs about 3.8 GB of VRAM for weights plus activation overhead at 1024×1024. The FP16 checkpoint needs about 9.2 GB, so an 8 GB GPU should use FP16 with VAE tiling or the FP16 variant with encoders offloaded, and any 12 GB GPU runs SDXL FP16 with headroom.
At Q4_K_M quantization with 4,096 context, the Stable Diffusion XL 1.0 requires approximately 3.81GB of VRAM. The GeForce RTX 5060 Ti 16GB has 16GB available (12.19GB headroom).

Frequently Asked Questions
Can the Stable Diffusion XL 1.0 run on 16GB VRAM?
Yes. At Q4_K_M quantization with 4K context, the Stable Diffusion XL 1.0 needs approximately 3.81GB. Your 16GB of usable memory has 12.19GB headroom.
What is the maximum context length I can use on the GeForce RTX 5060 Ti 16GB?
The Stable Diffusion XL 1.0 supports up to 32,768 tokens of context. Larger context increases KV-cache memory requirements. At 4K context the model needs ~3.81GB; at 32K it needs more.
Which quantization should I use with the GeForce RTX 5060 Ti 16GB?
Q4_K_M is the recommended starting point — it offers the best speed-to-quality tradeoff. If you have VRAM headroom, Q6_K or Q8_0 improves quality at the cost of speed. FP16 is only for inference servers with ample memory.
Can a 6 GB GPU run SDXL?
Yes, with GGUF Q4 or Q5 quantized checkpoints, which need about 3.8–4.7 GB of VRAM including activation overhead. Expect 1–2 minutes per 1024×1024 image on a 6 GB card such as the RTX 2060.
How much VRAM does SDXL need at FP16?
SDXL 1.0 needs about 9.2 GB of VRAM at FP16 for 1024×1024 generation, calculated from the 6.9 GB checkpoint plus 10% overhead plus 1.5 GB of activations, so 8 GB cards need VAE tiling or encoder offload.
