Performance comparison: which is faster?
GeForce RTX 3080 Ti (NVIDIA, 2021) and NVIDIA RTX A5000 (NVIDIA, 2020) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: nearly equal
For generative AI, the higher-VRAM RTX A5000（24GB） 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 | RTX 3080 Ti | RTX A5000 |
|---|---|---|
| Performance Score | 26,000 | 26,000 |
| VRAM | 12GB | 24GB |
| Manufacturer | NVIDIA | NVIDIA |
| Series | RTX 30 | Workstation |
| Release Year | 2021 | 2020 |
| Compatible CPU Example | Core i5-14600 | Core i5-14600 |
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 RTX A5000 also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RTX 3080 Ti |
| Run larger generative AI and LLM models | RTX A5000 |
| Prioritize value and adequate performance | RTX 3080 Ti (the lower model is often sufficient) |
Their scores are nearly identical (RTX 3080 Ti: 26000 points / RTX A5000: 26000 points). In this case, compare price, VRAM, and power draw.
RTX 3080 Ti has 12GB of VRAM, while RTX A5000 has 24GB; RTX A5000 has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, Core i5-14600 pairs well with RTX 3080 Ti and Core i5-14600 with RTX A5000 (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
