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.

None of the retailers we track lists a new AMD Ryzen 9 3900X 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.

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 AMD Ryzen 9 3900X 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 AMD Ryzen 9 3900X?
For the same capability today, the closest current product is AMD Ryzen 9 5900XT; for a meaningful step up, Intel Core Ultra 5 250KF Plus 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 AMD Ryzen 9 3900X.
