# Intel C++ compiler

6 Hacker News commenters recommended Intel C++ compiler and 7 criticized it, November 2025 to November 2026. It was recommended in 6 of 13 months.

**Verdict:** People recommend it for fast, tight code on Intel chips, often beating gcc. Critics say it can handicap AMD CPUs and its defaults can cut float precision.

## Why people recommend it

- Fast, tightly optimized generated code (3 comments): "the intel compiler unsurprisingly generated the most close asm for the machine" ([source](https://news.ycombinator.com/item?id=47533458)) "Often it’s faster than my own instrinsics, though not always." ([source](https://news.ycombinator.com/item?id=45833551)) "still around working far better than gcc in many use-cases" ([source](https://news.ycombinator.com/item?id=48972873))

## What people warn about

- Favors Intel, handicaps AMD CPUs (2 comments): "optimised per family, included all the copies in the output and selected the worst one on AMD" ([source](https://news.ycombinator.com/item?id=47711200)) "giving AMD cpu's a handicap" ([source](https://news.ycombinator.com/item?id=46031704))
- Default settings reduce float precision (2 comments): "sacrifices IEEE 764 float precision and go down to ~14 digits of precision in it's defaults" ([source](https://news.ycombinator.com/item?id=46676567)) "it incorrectly defaults to something like -funsafe-math" ([source](https://news.ycombinator.com/item?id=49699466))
- Benchmark tuning and wasted effort (2 comments): "Both that and the SPEC compiler shenanigans are cheating by changing the test" ([source](https://news.ycombinator.com/item?id=47918069)) "money they've wasted trying to improve autovectorization passes in ICC" ([source](https://news.ycombinator.com/item?id=48166083))
