How fast are the RTX A5000 and RTX A4000?

HOSTKEY engineers compared the performance and cost of GPU servers built with the RTX A5000/A4000, RTX 3090 and GTX 1080Ti / 1080 cards using a machine learning problem as a trial. This study will help you evaluate the capabilities of the cards and their cost-effectiveness in solving a specific task related to the operation of a neural network.

The work of neural networks on servers built with RTX A5000 and RTX A4000 cards is comparable to the speed on servers with RTX 3090/3080 cards. And the cost of training models on servers with RTX A5000 and RTX A4000 cards is up to 12 times cheaper than on cloud GPU platforms such as AWS, Google Cloud and Microsoft Azure.
