A grade answers “how well does this handle that job?” — price is never part of it. We are not tracking a verified offer right now, so there is no Relative Value to show against it.

Performance and where it ranks
Two different questions, side by side. Performance compares what the hardware can do; Value compares what that capability costs at today’s price. A product can rank high on one and low on the other — that gap is the point.

RX 6400 in today's market
We are not tracking a current offer for RX 6400 in Canada right now. The last offers we observed are listed below as history; capability, ranks and specifications do not depend on them.

These are historical snapshots from tracked retailers. They are not presented as currently available, and they never count toward Value, rankings or our offer data.
Someone is offering you a RX 6400? Check that price
Enter the asking price: it is scored against today's market under your priorities. Capability is the same at any price; only Value changes. Nothing is saved unless you save it as your deal.
Upgrade planner
Judge the change in the active scenario, then make the cash gap explicit.
Using page scenarioOwn a RX 6400? Enter what you could sell it for and how much more you would spend: we rank current upgrades by what they add for the money you actually put in.
Only candidates that clear the configured meaningful-upgrade gate will be shown; roles are omitted rather than filled.
Capability differences are expressed as tiers and index points, not as benchmark percentages we did not measure.

This scenario carries a requirement candidates are checked against first: CUDA — Many local-LLM and diffusion toolchains are CUDA-only. ROCm and Vulkan builds exist and work, but they are not drop-in — check your toolchain before treating a non-NVIDIA card as an equivalent swap.
Chosen for Light Use
Chosen by capability in the same scenario against today's market: the closest current product that is not a downgrade, the cheapest current product within 10% of its capability, and the best Value among products at least 30% more capable.

FAQ
Why is there no current price for the RX 6400?
None of the retailers we track lists a new RX 6400 today. We keep the last offers we observed as dated history, but we do not present them as today's price and they never enter Value or rankings. Capability grades and specifications do not depend on an offer and stay current.
What is a fair used price for the RX 6400?
It depends on what today's market offers for the same money, not on a percentage of an old price. Enter the asking price in the price check on this page: it scores the RX 6400 at that price against current products under your priorities and shows the prices at which its Value would be strong.
What should I upgrade to from the RX 6400?
For the same capability today, the closest current product is RX 6500 XT 4GB; for a meaningful step up, RX 9070 XT is the best Value among products at least 30% more capable. The upgrade planner on this page ranks options by what they add for the money you actually spend after selling your RX 6400.
