Performance comparison: which is faster?
Radeon R7 370 (AMD, 2014) and Radeon HD 7790 (AMD, 2012) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: R7 370 is about 6.7% faster
For generative AI, the higher-VRAM R7 370（4GB） 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 | R7 370 | HD 7790 |
|---|---|---|
| Performance Score | 3,200 | 3,000 |
| VRAM | 4GB | 1GB |
| Manufacturer | AMD | AMD |
| Series | R7 | HD 7000 |
| Release Year | 2014 | 2012 |
| Compatible CPU Example | Core 2 Quad Q9550 | AMD Phenom II X2 560 |
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 R7 370 also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | R7 370 |
| Run larger generative AI and LLM models | R7 370 |
| Prioritize value and adequate performance | HD 7790 (the lower model is often sufficient) |
R7 370 is about 6.7% higher by score (R7 370: 3200 points / HD 7790: 3000 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.
R7 370 has 4GB of VRAM, while HD 7790 has 1GB; R7 370 has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, Core 2 Quad Q9550 pairs well with R7 370 and AMD Phenom II X2 560 with HD 7790 (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
