Relative Value is the 0–100 benefit/cost result computed within the current in-stock frame for each preset; the frame leader is 100 and other products show their relative share. Target prices are calculation thresholds under today's dataset; where none exist, the row says so instead of showing blanks. Recalculated on every data refresh.

Prices are the cheapest total (item plus shipping) we recorded for a New, in-stock offer on that day. Value and rank here are measured against products on sale now — the set this product actually competes in — so they will not match a Value Score computed over the whole catalogue elsewhere on this page. A previous-generation part is ranked among previous-generation parts, because that is the choice a buyer of one is actually making.

Confirm your motherboard socket and BIOS support this CPU, and that your cooler is rated for its sustained power limits.
Measured power & efficiency
Real measured package power for the Intel Core i9-13900K, not an estimate. Source: TechPowerUp (CPU-only package power, measured). The nameplate TDP is 253 W — measured all-core draw is higher (279 W), which is exactly why we grade on measured watts, not the rating.
| Workload | Measured power | Work / watt | |
|---|---|---|---|
| In games (CPU-only) | 145 W | 7.5 pts/W | gaming work per watt |
| Sustained all-core (CPU-only) | 279 W | 5.9 pts/W | all-core work per watt |
Idle draw of 58 W is whole-system (board + GPU + PSU), not CPU-only — it reflects the platform far more than the chip, so it is shown for reference and never used for an efficiency grade.
Best alternatives to the Intel Core i9-13900K at similar prices
Chosen for Productivity, not for general performance — a product that suits a different job is not an alternative here. Tiers come from the same rubric as the tier list; products we can't grade for this job are left out rather than guessed at. Prices use the page's dated offer frame.
Used Intel Core i9-13900K price & upgrade math (calculated)
We don't track live used-market listings yet, so here is an honest calculated guide instead. The cheapest new Intel Core i9-13900K in the 2026-09-11 offer frame is $449. Two yardsticks for a unit in excellent condition: 80% of the cheapest new price ≈ $359, and $182 — the price at which its Value Score reaches a perfect 100 in its strongest scenario (balanced). The lower of the two, ≈ $182, is a sensible ceiling if you're buying used and a realistic asking price if you're selling. Discount further for age, missing cooler or box, or a short remaining warranty — and score any real listing in the calculator.
FAQ
- What is a good price for the Intel Core i9-13900K right now?
- The price targets at the top of this page are calculation thresholds, not forecasts: they say what the competing offers in the 2026-09-11 frame would have to be beaten by under the balanced weighting. Two caveats worth knowing — they move when the rest of the market moves, even if this product's own price doesn't; and hitting a target says the PRICE is good, not that the product suits your job (that's what the tier badges above answer). Change the weighting in the calculator and the targets change with it.
