Performance comparison: which is faster?
Radeon HD 7850 (AMD, 2012) and Radeon R7 370 (AMD, 2014) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: HD 7850 is about 12.5% 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 | HD 7850 | R7 370 |
|---|---|---|
| Performance Score | 3,600 | 3,200 |
| VRAM | 2GB | 4GB |
| Manufacturer | AMD | AMD |
| Series | HD 7000 | R7 |
| Release Year | 2012 | 2014 |
| Compatible CPU Example | AMD Athlon II X4 640 | Core 2 Quad Q9550 |
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 | HD 7850 |
| Run larger generative AI and LLM models | R7 370 |
| Prioritize value and adequate performance | R7 370 (the lower model is often sufficient) |
HD 7850 is about 12.5% higher by score (HD 7850: 3600 points / R7 370: 3200 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.
HD 7850 has 2GB of VRAM, while R7 370 has 4GB; 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, AMD Athlon II X4 640 pairs well with HD 7850 and Core 2 Quad Q9550 with R7 370 (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
