It all depends on what characteristics you are looking for.
Here is some information on the different GPU models and see which one suits you best.
Here you can see that.
- FP32 -which stands for 32 bit floating point which is a measure of how fast this GPU card with single precision floating point operations. It is measured in TFLOPS or Tera Floating point operations.
- Price- Hourly price on GCP
- TFLOPS/Price- simply put how much operations will you get for one dollar
You can see that Nvidia A100 is the fastest.
Nvidia Tesla P4 is the slowest.
Nvidia A100 is the most expensive while Tesla P4 is the cheapest.
While Tesla P4 has the highest operations per dollar, A100 has the lowest operations per dollar.
