Quick Verdict
On the sourced faculty-count and ranking data, IIT Guwahati (IITG) -- established in 1994 in Guwahati, Assam -- has a modest edge over IIT (BHU) Varanasi -- based in Varanasi, Uttar Pradesh, and a full Indian Institute of Technology (IIT) only since 2012, though its roots as a technical institute go back to 1919. IIT Guwahati has meaningfully more faculty on a similar-sized student body and a higher NIRF (National Institutional Ranking Framework) Engineering rank in the most recent year-over-year figures available, while IIT BHU Varanasi counters with a stated institutional push toward interdisciplinary research and a broader traditional-engineering specialization list at the postgraduate level.

Detailed Analysis
The clearest, most direct comparison in the sourced data is faculty headcount against student body size. IIT Guwahati has 539 faculty members for 7,849 students, while IIT BHU Varanasi has 381 faculty for a slightly larger student body of 7,980 (Wikipedia). In plain terms, IIT Guwahati has noticeably more faculty teaching and supervising a comparable number of students, which points toward smaller class sizes and more faculty attention per student at Guwahati, at least on paper. For context, the IIT system as a whole is said to maintain a faculty-to-student ratio between 1:6 and 1:8, with the IIT Council's Standing Committee prescribing a department-wise lower limit of 1:9 (Wikipedia) -- though that's a system-wide figure, not a number broken out for either institute individually, so it should be read as general context rather than a precise measurement of either institute's actual ratio.
On national rankings, IIT Guwahati held a clear lead over IIT BHU Varanasi in the NIRF Engineering rankings for 2023, coming in at 7th nationally versus BHU Varanasi's 15th (pw.live). NIRF factors in teaching and learning resources, research output, graduation outcomes, outreach, and perception, so this is a broad academic-quality signal rather than a faculty-specific one, but it's still one of the more concrete, comparable data points available here.
The two institutes also show a real difference in academic character through their M.Tech specialization offerings. IIT Guwahati's list leans toward newer, often interdisciplinary and earth/environment-facing fields: Aerodynamics and Propulsion, Structural Engineering, Earth System Science and Engineering, Water Resources Engineering and Management, Geotechnical Engineering, Environmental Engineering, Transportation Systems Engineering, Infrastructure Engineering and Management, Biotechnology, Bioengineering, Petroleum Science and Technology, and Materials Science and Technology (pw.live). IIT BHU Varanasi's list reflects its history as a mining-and-metallurgy-focused institute before its IIT conversion: Computer Science and Engineering, Decision Sciences and Engineering, Biochemical Engineering, Electrical Engineering, Electronics Engineering, Mechanical Engineering, Mining Engineering, Metallurgical Engineering, Systems Engineering, and Civil Engineering (pw.live). Both institutes accept M.Tech applicants via GATE (Graduate Aptitude Test in Engineering) scores followed by COAP (Common Offer Acceptance Portal) counseling, or via valid JEE Main/JEE Advanced scores, and both allow direct M.Tech admission without GATE for IIT B.Tech graduates with a CPI (Cumulative Performance Index) of 8.0 or above applying for a Teaching Assistant role (pw.live) -- so admission pathways are essentially at parity.
IIT BHU Varanasi's own leadership frames its academic direction explicitly: Director Amit Patra has said the institute is dedicated to "becoming a beacon of modern interdisciplinary technological advancement in the country," and that it aims "not just to keep] pace with the rapidly evolving landscape of science and technology, but also... to lead the charge, pioneering innovations that shape the future," adding that IIT (BHU) will "give more and more emphasis to inter-disciplinary research and collaboration with the industry and international peers to position ourselves in the top-rung of educational Institutions in our country and abroad" ([iitbhu.ac.in). That's a stated institutional ambition rather than a measured outcome, so it should be read as intent, not proof of current standing.
Verdict
Based on the available data, IIT Guwahati wins on Faculty and Academics, largely on the strength of its higher faculty count relative to student body and its clearly higher NIRF Engineering rank in 2023 (7th versus 15th). IIT BHU Varanasi is the runner-up, and a reader should lean toward it instead if they specifically want deep, traditional core-engineering specializations like mining and metallurgical engineering, or if they're drawn to the institute's explicitly stated push toward interdisciplinary research and international collaboration under its current leadership -- factors this data set can document as intent but not yet as a measured academic outcome.
Frequently Asked Questions
Q: Which institute has more faculty?
IIT Guwahati, with 539 faculty versus IIT BHU Varanasi's 381 (Wikipedia).
Q: Which institute has more students?
IIT BHU Varanasi, marginally -- 7,980 versus IIT Guwahati's 7,849 (Wikipedia).
Q: Which institute ranked higher on NIRF Engineering in 2023?
IIT Guwahati, at 7th, versus IIT BHU Varanasi's 15th (pw.live).
Q: What is the IIT system's typical faculty-to-student ratio?
Between 1:6 and 1:8 system-wide, with a department-wise lower limit of 1:9 set by the IIT Council's Standing Committee -- though this figure isn't broken out separately for either institute (Wikipedia).
Q: Does IIT BHU Varanasi offer Computer Science and Engineering at the M.Tech level?
Yes, it's on its list of M.Tech specializations (pw.live).
Q: Does IIT Guwahati offer core mining or metallurgical engineering at the M.Tech level?
No -- based on the sourced specialization list, those fields (Mining Engineering, Metallurgical Engineering) appear under IIT BHU Varanasi, not IIT Guwahati (pw.live).
Q: Can students get into either institute's M.Tech program without a GATE score?
Yes -- both allow direct M.Tech admission for IIT B.Tech graduates with a CPI of 8.0 or above, applying for a Teaching Assistant position (pw.live).
Q: When did IIT BHU Varanasi become a full IIT?
In 2012, though the institute itself traces back to 1919 as the Institute of Technology, Banaras Hindu University (Wikipedia).
