NVIDIA RTX 5080

The NVIDIA RTX 5080 has 16 GB VRAM and 960 GB/s memory bandwidth. It can run 40 of our 70 tracked models natively in VRAM at 8k context.

The NVIDIA RTX 5080 is the second-tier Blackwell GPU, with 16GB GDDR7 on a 256-bit bus at 960 GB/s. Its 10,752 CUDA cores and 336 Tensor Cores make it a strong 1440p–4K gaming card, but the 16GB VRAM cap limits it to 7B–14B models for LLM inference without offloading.

The NVIDIA RTX 5080 is a consumer-grade NVIDIA GPU based on the Blackwell architecture. Released in 2025. It features 16 GB of GDDR7 at 960 GB/s memory bandwidth. Full llama.cpp and Ollama support out of the box. CUDA 12.x recommended; driver ≥ 525 required.

For local LLM inference, this GPU runs 40 of the 70 models we track natively in VRAM at 8K context. The largest model it handles in VRAM is Qwen 3.5 35B-A3B (MoE) (1069.9 t/s at Q2_K). It handles smaller models up to ~7-14B at reasonable precision, with some 27-32B models fitting at lower quantization. On Qwen 3.6 27B, it achieves approximately 82.7 tokens per second at Q3_K_M quantization. An additional 9 models fit with CPU offload — slower but usable.

NVIDIA's CUDA ecosystem provides broad out-of-the-box support across llama.cpp, Ollama, vLLM, and TensorRT-LLM. Among consumer GPUs, it sits above NVIDIA RTX 5070 Ti and NVIDIA RTX 3090 in performance, but below AMD Radeon RX 7900 XTX.

These use system RAM for layers that don't fit in VRAM — expect much slower inference.
