Performance comparison: which is faster?
Radeon RX 7900 GRE (AMD, 2024) and AMD Instinct MI100 (AMD, 2020) are compared here. Compare scores and VRAM, generative AI usability, and CPUs that pair well with each GPU.
Overall performance: RX 7900 GRE is about 14% faster
For generative AI, the higher-VRAM Instinct MI100（32GB） 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 7900 GRE | Instinct MI100 |
|---|---|---|
| Performance Score | 28,500 | 25,000 |
| VRAM | 16GB | 32GB |
| Manufacturer | AMD | AMD |
| Series | RX 7000 | Instinct |
| Release Year | 2024 | 2020 |
| Compatible CPU Example | Ryzen 9 7950X3D | Core Ultra 7 165H |
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 Instinct MI100 also run here)
| If You Want To... | Recommended |
|---|---|
| Prioritize high fps and smooth performance in demanding games | RX 7900 GRE |
| Run larger generative AI and LLM models | Instinct MI100 |
| Prioritize value and adequate performance | Instinct MI100 (the lower model is often sufficient) |
RX 7900 GRE is about 14% higher by score (RX 7900 GRE: 28500 points / Instinct MI100: 25000 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 7900 GRE has 16GB of VRAM, while Instinct MI100 has 32GB; Instinct MI100 has more. If image generation or a local LLM is even a possibility, the higher-VRAM option provides more room.
Using our guideline, Ryzen 9 7950X3D pairs well with RX 7900 GRE and Core Ultra 7 165H with Instinct MI100 (CPU:GPU ≈ 0.9:1). If the CPU is too weak, replacing the GPU may not raise fps, so check the combination before buying.
