Check GPU compatibility by desktop model.

Explore graphics card fit and local-model memory requirements, with cited sources and confidence grades.

Find your desktop by model. Each page lists the graphics cards its published specifications accept, the conditions attached, and the local language models that fit in each card's memory. Each verdict cites the documents it rests on and carries a confidence grade; the figures a verdict turns on carry their own source and grade.

We do not test hardware. We have not physically tested this combination. Data is compiled from official specification sheets and cited sources. Verify with the manufacturer before purchasing.

82 desktop models, 242 graphics cards and 18 local language models. Verdicts describe what the specifications imply, never what happened when someone tried it.

Graphics cards

Cards that appear in at least one verdict. Entries marked as a factory option are graphics choices a computer manufacturer lists in its own specification sheet; no card-level specification is published for them, so those pages carry no specification table and no purchase link.

Local language models

Each model page publishes the arithmetic behind its memory requirement, so you can redo it.

How to read a verdict

What each verdict means. Every one of them is a statement about published specifications.
VerdictMeaning
✓ Fits Published specifications show no physical or electrical conflict.
△ Fits with conditions Published specifications allow it only under the stated conditions.
✕ Does not fit Published specifications rule the combination out: the card needs a connector the machine does not have, draws more than the supply provides, or is physically too large. It is a statement about specifications, not a report of a failed attempt.
? Unverified There is not enough evidence to say.
Confidence grades, as the underlying database assigns them. See Methodology.
GradeWhat the grade means
AStated explicitly in the manufacturer's own specification sheet or manual
BDerived logically from official specifications and published standards (nobody states the combination; the numbers do)
CVerified on physical hardware
DThird-party measurement or article
EUser report only

A definite verdict is made only on grade A, B or C evidence. Grade D or E evidence alone produces an estimate, shown with a dashed Estimated badge.

The full method, including the memory sizing rule and its constants, is on the Methodology page.
