Free AI hardware database and decision tools. Specs, calculators, and live cloud pricing so you can choose GPUs and infrastructure with confidence — no signup, no paywall.
AI hardware decisions are expensive to get wrong. Buy the wrong GPU and you waste money; over-rent cloud and you burn budget; under-size VRAM and your model will not run.
HardwareHQ is a free database and set of decision tools: live cloud pricing, VRAM and TCO calculators, compatibility checks, and planning studios — so builders can choose with confidence.
All core tools are free with no signup required. We earn revenue through affiliate partnerships with cloud GPU providers and hardware retailers. Affiliate links are always disclosed and never influence our recommendations or data.
VRAM requirements for every quantization level. Updated as new models release.
Consumer and enterprise specs. From RTX 4060 to H100.
Know in seconds if a model fits your VRAM. No guessing.
Automated pipeline keeps data fresh. New models added within days of release.
All tools work without signup. We don't collect personal data or require authentication.
We don't track you, sell your data, or require accounts. Your hardware choices are yours alone.
Some hardware links are affiliate links. We earn a small commission if you purchase, at no extra cost to you. Affiliate links are always marked and never influence our recommendations.
GPU and model data is available via REST API for free use. Rate limits may apply to protect the service. For higher-volume access, email hardwarehq.dev@gmail.com. Core web tools stay free for everyone.
