Performance comparison: which is faster?
NVIDIA Quadro RTX 8000 (NVIDIA, 2018) and GeForce RTX 3080 (NVIDIA, 2020) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: Quadro RTX 8000 is about 2% faster
For generative AI, the higher-VRAM Quadro RTX 8000（48GB） has the advantage. For gaming, prioritize performance score and CPU compatibility; for AI, prioritize VRAM.
Relative performance score (higher is faster). Actual fps varies by resolution, game, and CPU configuration.
| Item | Quadro RTX 8000 | RTX 3080 |
|---|---|---|
| Performance Score | 25,000 | 24,500 |
| VRAM | 48GB | 10GB |
| Manufacturer | NVIDIA | NVIDIA |
| Series | Workstation | RTX 30 |
| Release Year | 2018 | 2020 |
| Compatible CPU Example | Core Ultra 7 165H | Ryzen 5 8600G |
These generative AI models can run on only one GPU because of the VRAM difference (Stable Diffusion, Flux, LLMs, and others).
— None (all models that run on Quadro RTX 8000 also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | Quadro RTX 8000 |
| Run larger generative AI and LLM models | Quadro RTX 8000 |
| Prioritize value and adequate performance | RTX 3080 (the lower model is often sufficient) |
Quadro RTX 8000 is about 2% higher by score (Quadro RTX 8000: 25000 points / RTX 3080: 24500 points). Actual fps also varies by resolution, game, and CPU, so price is a reasonable deciding factor when the gap is only a few percent.
Quadro RTX 8000 has 48GB of VRAM, while RTX 3080 has 10GB; Quadro RTX 8000 has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, Core Ultra 7 165H pairs well with Quadro RTX 8000 and Ryzen 5 8600G with RTX 3080 (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
