Where it stands in the field
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.

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.
