Quick Verdict
On the resources that typically underpin research capacity — faculty size, institutional budget, and global research-linked rankings — IIT Kharagpur (in West Bengal) has a larger base than IIT Guwahati (in Assam). But Guwahati has built a specific reputation for cutting-edge research facilities and interdisciplinary work despite its smaller size, so the "better" choice depends on whether a reader wants a bigger research ecosystem or a more tightly-focused interdisciplinary one.

Detailed Analysis
IIT Kharagpur, established in 1951 as India's first IIT, is described by VedPrep as holding "superior global recognition (QS Rank 270)," which it credits as making Kharagpur "a top choice for legacy placements and research" (VedPrep) — note this QS figure (270) differs somewhat from the QS World University Ranking 2024 figure of 285 reported elsewhere, likely reflecting different snapshot years or ranking editions (pw.live). Regardless of the exact number, Kharagpur consistently outranks Guwahati on QS's global list, and the gap is largest on the QS World Engineering & Technology subject ranking specifically (74 vs 301–350 in 2023) (pw.live) — a ranking that weighs research reputation and citations heavily, making it a reasonable (if indirect) proxy for research standing in engineering fields. Kharagpur also runs the largest PhD program of the two, with 27 doctoral tracks against Guwahati's 12 (pw.live), and its much larger faculty base (928, versus Guwahati's 539) and bigger institutional budget (roughly ₹1,302 crore versus roughly ₹442 crore) point to a larger overall research capacity in absolute terms (Wikipedia).
IIT Guwahati, established in 1994 under the Assam Accord as the sixth IIT, is repeatedly described in the sourced material as known for its "cutting-edge research facilities and emphasis on interdisciplinary studies" (GeeksforGeeks), and VedPrep specifically credits it with excelling in "interdisciplinary engineering" (VedPrep). With a smaller faculty pool and budget than Kharagpur, Guwahati's research output is necessarily smaller in raw volume, but its newer campus and facilities (built out largely since 1994, versus Kharagpur's much older infrastructure) may offer more modern lab and equipment setups in specific areas — though the sourced material doesn't provide facility-by-facility detail to confirm this directly.
Importantly, the research fact-base available for this comparison does not include hard, institute-specific research output metrics — no comparable data on annual publication counts, patents filed, sponsored research funding, or number of active research centers at either institute. A large table of individual funded research projects exists in the broader source material, but it lists projects at IIT Bombay and IIT Ropar, not IIT Kharagpur or IIT Guwahati, so it isn't usable for this comparison. That means the research-capacity comparison here rests on institutional scale (faculty, budget, PhD tracks) and rankings, not on direct measures of research productivity.
Verdict
IIT Kharagpur is the stronger pick for Research Opportunities in terms of sheer scale — more faculty, a bigger budget, more PhD tracks, and stronger engineering-specific global rankings all point to a larger and more established research ecosystem. The one condition under which a reader should pick IIT Guwahati instead is if the goal is working in a smaller, close-knit, interdisciplinary research group rather than a large, legacy-heavy institution — Guwahati's specific reputation for interdisciplinary and cutting-edge facility work suggests it can be the better fit for that narrower goal, even without matching Kharagpur's overall scale.
Frequently Asked Questions
Q: Which IIT has more faculty available for research supervision?
IIT Kharagpur, with 928 faculty members versus Guwahati's 539 (Wikipedia).
Q: Which institute has a bigger research-relevant budget?
The sourced data only gives total institutional budgets, not research-specific budgets: Kharagpur's is roughly ₹1,302 crore versus Guwahati's roughly ₹442 crore (Wikipedia).
Q: How many PhD program tracks does each institute offer?
27 at IIT Kharagpur versus 12 at IIT Guwahati (pw.live).
Q: Is IIT Guwahati known for anything specific in research?
Yes — it's repeatedly described as strong in interdisciplinary studies and for having cutting-edge research facilities (GeeksforGeeks; VedPrep).
Q: Is there data on publication counts or patents for either institute?
No — the sourced research doesn't include institute-specific publication, patent, or sponsored-research-funding figures for Kharagpur or Guwahati, so no claims can be made on those specifics.
Q: Which institute ranks higher globally for engineering research reputation (QS)?
IIT Kharagpur, at 74th on the QS World Engineering & Technology ranking in 2023, versus Guwahati's 301–350 band (pw.live).
Q: Does Kharagpur's age give it a research advantage?
It plausibly does, given its much larger faculty base and budget accumulated since 1951 versus Guwahati's 1994 founding, but the sourced material doesn't offer a direct causal analysis, only the scale figures themselves (Wikipedia).
