Performance comparison: which is faster?
Radeon RX 470 (AMD, 2016) and Radeon HD 7970 (AMD, 2012) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: RX 470 is about 12.7% faster
For generative AI, the higher-VRAM RX 470（8GB） 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 | RX 470 | HD 7970 |
|---|---|---|
| Performance Score | 6,200 | 5,500 |
| VRAM | 8GB | 3GB |
| Manufacturer | AMD | AMD |
| Series | RX 500 | HD 7000 |
| Release Year | 2016 | 2012 |
| Compatible CPU Example | AMD A10-7890K | AMD FX-4300 |
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 RX 470 also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RX 470 |
| Run larger generative AI and LLM models | RX 470 |
| Prioritize value and adequate performance | HD 7970 (the lower model is often sufficient) |
RX 470 is about 12.7% higher by score (RX 470: 6200 points / HD 7970: 5500 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.
RX 470 has 8GB of VRAM, while HD 7970 has 3GB; RX 470 has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, AMD A10-7890K pairs well with RX 470 and AMD FX-4300 with HD 7970 (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
