Changelog

Hardware patch notes. When GPUs launch or models drop, the arena updates — we publish what changed.

The AI hardware space is loud and young. Reviews are either breathless launch coverage or dry whitepapers. Benchmarks are scattered across GitHub issues, Reddit threads, and vendor marketing. There's no trusted middle ground for operators who need to pick a GPU tier on Monday, a cluster topology by Friday, and an edge device by next quarter.

MadCoolStuff sits in that middle. Not breathless, not academic — the voice of someone who has to actually buy the thing.
