# GPU Support for Talk2Me
## Current GPU Support Status
### ✅ NVIDIA GPUs (Full Support)
- **Requirements**: CUDA 11.x or 12.x
- **Optimizations**:
- TensorFloat-32 (TF32) for Ampere GPUs (RTX 30xx, A100)
- cuDNN auto-tuning
- Half-precision (FP16) inference
- CUDA kernel pre-caching
- Memory pre-allocation
### ⚠️ AMD GPUs (Limited Support)
- **Requirements**: ROCm 5.x installation
- **Status**: Falls back to CPU unless ROCm is properly configured
- **To enable AMD GPU**:
```bash
# Install PyTorch with ROCm support
pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/rocm5.6
```
- **Limitations**:
- No cuDNN optimizations
- May have compatibility issues
- Performance varies by GPU model
### ✅ Apple Silicon (M1/M2/M3)
- **Requirements**: macOS 12.3+
- **Status**: Uses Metal Performance Shaders (MPS)
- **Optimizations**:
- Native Metal acceleration
- Unified memory architecture benefits
- No FP16 (not well supported on MPS yet)
### 📊 Performance Comparison
| GPU Type | First Transcription | Subsequent | Notes |
|----------|-------------------|------------|-------|
| NVIDIA RTX 3080 | ~2s | ~0.5s | Full optimizations |
| AMD RX 6800 XT | ~3-4s | ~1-2s | With ROCm |
| Apple M2 | ~2.5s | ~1s | MPS acceleration |
| CPU (i7-12700K) | ~5-10s | ~5-10s | No acceleration |
## Checking Your GPU Status
Run the app and check the logs:
```
INFO: NVIDIA GPU detected - using CUDA acceleration
INFO: GPU memory allocated: 542.00 MB
INFO: Whisper model loaded and optimized for NVIDIA GPU
```
## Troubleshooting
### AMD GPU Not Detected
1. Install ROCm-compatible PyTorch
2. Set environment variable: `export HSA_OVERRIDE_GFX_VERSION=10.3.0`
3. Check with: `rocm-smi`
### NVIDIA GPU Not Used
1. Check CUDA installation: `nvidia-smi`
2. Verify PyTorch CUDA: `python -c "import torch; print(torch.cuda.is_available())"`
3. Install CUDA toolkit if needed
### Apple Silicon Not Accelerated
1. Update macOS to 12.3+
2. Update PyTorch: `pip install --upgrade torch`
3. Check MPS: `python -c "import torch; print(torch.backends.mps.is_available())"`
