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.

These ladders follow the preset scenario shown above. Your own weights re-score this product, not the whole field.

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.

Works well if

Consider other options if
- You want strong value with Balanced priorities specificallyat today's market no realistic price for this model reaches strong value with Balanced priorities — the calculation only gets there near CAD 35, against a cheapest tracked CAD 99

What to check in your build
LGA 1151 required
Your motherboard must use socket LGA 1151. 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 154 W or more
No cooler is included. Your cooler must be rated for at least 154 W on socket LGA 1151.

Summary
Intel Core i5-8400 offers a balanced view across an all-round mix of priorities. It ranks #194 by capability in the current modelled field. Its clearest measured strength is multi-thread index 260. The main limitation appears when Productivity becomes the priority, where it grades F.
Intel Core i5-8400 offers C-grade capability for Gaming. It ranks #194 by capability in the current modelled field. Its clearest measured strength is multi-thread index 260. The C grade is the decisive limitation for this workload.
Intel Core i5-8400 offers F-grade capability for Productivity. It ranks #194 by capability in the current modelled field. Its clearest measured strength is multi-thread index 260. The F grade is the decisive limitation for this workload.
Intel Core i5-8400 offers F-grade capability for Performance per Watt. It ranks #191 by capability in the current modelled field. Its clearest measured strength is multi-thread index 260. The F grade is the decisive limitation for this workload.
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 listing snapshots can participate in Value while fresh. We show Check on Amazon instead of its price; confirm the current price and availability at the store. When no current listing snapshot exists, Amazon is a search link only.
