The V100 is ~8 years old and AFAIK mostly not that common anymore, but the A100 is ~5.5 years old now and is still very commonly used, it's maybe the most common HPC cluster GPU. On the consumer side, 3090s are still very popular, representing a good balance between cost, performance and efficiency (this is mostly due to 4090s and 5090s being much more expensive).
