Performance comparison: which is faster?
GeForce RTX 3090 (NVIDIA, 2020) 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: RTX 3090 is about 1.9% faster
Both have 24GB of VRAM, so they support a similar range of generative AI models. 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 3090 | RTX A5000 |
|---|---|---|
| Performance Score | 26,500 | 26,000 |
| VRAM | 24GB | 24GB |
| Manufacturer | NVIDIA | NVIDIA |
| Series | RTX 30 | Workstation |
| Release Year | 2020 | 2020 |
| Compatible CPU Example | Ryzen 9 7900 | Core i5-14600 |
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RTX 3090 |
| Run larger generative AI and LLM models | RTX 3090 |
| Prioritize value and adequate performance | RTX A5000 (the lower model is often sufficient) |
RTX 3090 is about 1.9% higher by score (RTX 3090: 26500 points / RTX A5000: 26000 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.
Both have 24GB of VRAM, so the range of generative AI models they can run is nearly the same.
Using our guideline, Ryzen 9 7900 pairs well with RTX 3090 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.
