It all depends on what are the characteristics you're looking for.
First, let's collect some information about these different GPU models and see which one suits you best. You can google each model's name and see its characteristics. I did that and I created the following table:
Model |
FP32 (TFLOPS) |
Price |
TFLOPS/dollar |
Nvidia A100 |
19.5 |
2.933908 |
6.646425178 |
Nvidia Tesla T4 |
8.1 |
0.35 |
23.14285714 |
Nvidia Tesla P4 |
5.5 |
0.6 |
9.166666667 |
Nvidia Tesla V100 |
14 |
2.48 |
5.64516129 |
Nvidia Tesla P100 |
9.3 |
1.46 |
6.369863014 |
Nvidia Tesla K80 |
8.73 |
0.45 |
19.4 |
In the previous table, you see can the:
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's measured in TFLOPS or *Tera Floating-Point Operations... The higher, the better.
Price
: Hourly-price on GCP.
TFLOPS/Price
: simply how much operations you will get for one dollar.
From this table, you can see:
Nvidia A100
is the fastest.
Nvidia Tesla P4
is the slowest.
Nvidia A100
is the most expensive.
Nvidia Tesla T4
is the cheapest.
Nvidia Tesla T4
has the highest operations per dollar.
Nvidia Tesla V100
has the lowest operations per dollar.
And you can observe that clearly in the following figure:
I hope that was helpful!
