Hello @dyat, you're correct, functionally they're both the same except the only difference between teaching and research are the built-in HPC cores.

Teaching includes 4 HPC cores

Research allows up to 16 HPC cores.

For Teaching, Research and Associate licenses HPC capability is built into each task of the Academic base licenses. This is both shared and distributed memory HPC capability for up to 4 cores, plus GPU access is enabled for Ansys Mechanical, Fluent and Electronics solvers. For bundles including Research and Associate products there are 12 additional cores per license provided to be used across these two products.
