Which one is better , IIT Dharwad or IIT Tirupati, for CSE?

IIT Tirupati was started in 2015, and IIT Dharwad in 2016. As a student of CSE at IIT Dharwad, I can give you some details on my branch/college-

The CSE branch at IIT Dharwad receives internship offers from well-known companies like McAfee, Microsoft, Google, and some well reputed academic institutes. The CSE students qualify for GSoC in decent numbers, and the Open Student Society of IIT Dharwad conducts an Open Source Contribution Event during the summers. It is called ‘Summer of Innovation’, and it receives participants from across India, including the OS society of IIT Kharagpur. Dharwad is well-connected to major IT hubs- Pune, Bangalore, Mumbai and Hyderabad. IIT Dharwad is backed by a huge incubation center based in Hubli called Sandbox Startups. 

Based on my experience, I can assure you a rich learning environment at the IIT Dharwad CSE department.
