## Simple Benchmark

### Network Benchmark without batchnorm (TF32/F16) in Different GPUs

Basic (120k voxels): ```python -m spconv.benchmark bench_basic f16``` and ```python -m spconv.benchmark bench_basic tf32```

**NOTE** 
When you want to benchmark network in your laptop, don't forget to close all apps except terminals! Other apps will consume GPU resource and make kernels run slower.
