A computer dedicated to AI training and processing, the latter known as "inference." The training phase takes a lot of computer power, and datacenters with thousands, tens of thousands and even hundreds of thousands of GPU-based servers are used to create machine learning models; for example, see
Project Colossus.
Lots of Memory
The actual operation in both the training and inference stages of AI is massive amounts of math computations. As a result, AI servers typically have a lot of memory for both their CPUs and GPUs. Hundreds of gigabytes are not unusual. See
