Quick Verdict
IIT Madras is consistently the harder IIT to get into overall — it has been ranked the No. 1 engineering institute in India for nine straight years in the NIRF Engineering rankings, including 2025 (Shiksha, Careers360), while IIT Guwahati sits well below it, in the 7th–8th range on the same list (Careers360). Since JEE Advanced branch cutoffs broadly track institute reputation and demand, this means popular branches (Computer Science, Electrical Engineering) at Madras almost always close at a tighter (lower) rank than the same branches at Guwahati. Important caveat up front: the sourced material for this piece does not contain actual JEE Advanced opening/closing rank tables for either institute, so no specific numeric cutoff ranks can be cited here — the comparison below is built from the closest available proxies (institute-wide rankings, size, and branch-change policy).

Detailed Analysis
Reputation drives cutoffs, and Madras leads by a wide margin. IIT Madras has held the No. 1 spot on NIRF's engineering list for nine consecutive years, including 2025 (Shiksha), and also topped the NIRF 2025 overall ranking with a score of 91.69 against IIT Guwahati's 67.67 (NIRF). Because JEE Advanced candidates rank institutes (and branches within them) largely by reputation and outcomes, this gap in standing is the single best available signal that Madras' branch cutoffs — across nearly every stream, not just Computer Science — sit at tighter (numerically lower) closing ranks than Guwahati's.
IIT Guwahati's relative position has been slipping, not improving. Careers360 reports that IIT Guwahati held 7th place among engineering colleges in NIRF 2024, but in NIRF 2025 "IIT Hyderabad has broken into the top 10, overtaking IIT Guwahati," pushing it down a spot (Careers360). Note that two sourced tables disagree on the exact resulting number: Careers360's own top-10 table lists IIT Guwahati at rank 8 with IIT Hyderabad at 7 (Careers360), while a separate InfinityLearn summary table lists IIT Guwahati at 7 and IIT Hyderabad at 8 (InfinityLearn). We flag this discrepancy rather than pick one silently; what both sources agree on is the underlying trend — IIT Hyderabad has closed the gap with, or passed, IIT Guwahati recently, which is a headwind for Guwahati's relative standing and, by extension, its cutoffs.
Size and structure matter for how "hard" a branch is to get into. IIT Madras is also the larger institute by every metric in the sourced Wikipedia table: 674 faculty and 10,238 students against IIT Guwahati's 539 faculty and 7,849 students, and a budget of roughly ₹996 crore versus ₹442.38 crore (Wikipedia). A larger, better-funded institute with more seats does not automatically mean easier cutoffs — in Madras' case, higher demand than seat growth has kept it the most selective IIT overall — but it does mean more branch options and more redistribution room within the institute.
Branch-change policy is one real, sourced difference that affects how "locked in" a cutoff feels. The Wikipedia entry on IITs states that IIT Madras (along with IIT Bhilai, IIT Palakkad, and IIT Roorkee) allows meritorious first-year students to change departments after their first two semesters (Wikipedia). The same source notes several IITs — Bombay, Hyderabad, and Kharagpur — have abolished this practice to reduce student stress, but it does not state IIT Guwahati's current policy either way (Wikipedia). Practically, this means a student entering IIT Madras through a less popular branch has a sourced, merit-based path to move into a higher-cutoff branch later — an option we cannot confirm exists in the same form at IIT Guwahati based on the available facts.
Verdict
On branch cutoffs, IIT Madras is the clear winner by every available proxy — institute-wide NIRF rank, overall NIRF score, and a sourced branch-change policy that gives students a second chance at a better branch. IIT Guwahati is the reasonable runner-up, still a top-10 engineering institute nationally even as its relative position has softened against IIT Hyderabad in the most recent ranking cycle. The one condition under which a reader should pick IIT Guwahati over Madras on this specific axis: if your JEE Advanced rank realistically puts a strong branch (say, Computer Science or Electrical Engineering) at Guwahati within reach, but only a weaker or unpopular branch at Madras within reach — in that case, a strong branch at the "easier" institute is generally the better call than a weak branch at the more prestigious one. We cannot tell you the exact rank thresholds where that trade-off applies, because branch-wise cutoff numbers were not in the sourced material.
Frequently Asked Questions
Q: Which IIT has tougher branch cutoffs, Madras or Guwahati?
A: IIT Madras, based on its consistently higher NIRF rank and score; exact numeric closing ranks for specific branches were not available in the sourced data.
Q: Is Computer Science the toughest branch to get into at both institutes?
A: This is common knowledge across IITs generally, but the sourced facts here don't include branch-wise cutoff figures to confirm the exact ordering at Madras or Guwahati specifically.
Q: Can I switch branches after joining IIT Madras if I get a lower-ranked cutoff branch?
A: Yes — IIT Madras allows meritorious students to change departments at the end of their first two semesters (Wikipedia).
Q: Can I switch branches after joining IIT Guwahati?
A: Not confirmed by the sourced material either way; check IIT Guwahati's current academic regulations directly.
Q: Why is IIT Madras more selective than IIT Guwahati overall?
A: It has ranked No. 1 in NIRF's engineering list for nine consecutive years and topped the NIRF 2025 overall ranking with a 91.69 score versus Guwahati's 67.67 (Shiksha; NIRF).
Q: Has IIT Guwahati's ranking position changed recently?
A: Yes — it dropped one spot in NIRF's 2025 engineering list as IIT Hyderabad overtook it, though sources disagree on whether the resulting rank is 7 or 8 (Careers360; InfinityLearn).
Q: Does institute size (more seats) mean an easier cutoff?
A: Not necessarily — IIT Madras is larger than IIT Guwahati by faculty, students, and budget (Wikipedia), yet remains the more selective institute overall.
