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.

Balanced has no letter: it is a weighting preset, not a capability rubric. A grade answers “how well does this handle that job?” — price is never part of it. Relative Value puts the current market price back in.

Upgrade planner
Judge the change in the active scenario, then make the cash gap explicit.
Using page scenarioWhat are you upgrading from? These are the axes we compare on, and where this product stands in the current market.
We rank upgrades by out-of-pocket cost — the new price minus what yours is worth — not by sticker price.
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.

What to check in your build
AM4 required
Your motherboard must use socket AM4. A different socket does not fit — this is a physical constraint, not a preference.
Board BIOS must list this model
A matching socket is necessary but not sufficient — check the vendor CPU support list.
DDR4 memory
This processor takes DDR4. Memory of another generation does not fit the slots, even on a board with the right socket.
Cooler rated for 142 W or more
No cooler is included. Your cooler must be rated for at least 142 W on socket AM4.
Discrete GPU required

FAQ
Why does Relative Value change when I choose another scenario?
Each scenario changes the weights applied to capability, price and the other published factors. The hardware facts stay fixed, but the value question changes, so its score and rank can change too.
Why can Amazon appear without a tracked price?
Amazon is shown as a discovery link when we do not have a permitted verified price snapshot. It is excluded from price comparisons, rankings and Relative Value until a compliant tracked price exists.
