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.
Price & value history
What we actually observed — lowest tracked offer, average offer price, and value/rank position among products on sale now in this category.
- 📈 Up 6.2% since tracking began ($499 → $530).
- ↕️ Swing of $179 between $400 (2026-07-24) and $579 (2026-08-31).
Across 53 tracked days we recorded the Core Ultra 9 285K on 52 of them. The lowest tracked offer was $400 on 2026-07-24 and the highest $579 on 2026-08-31. Today's lowest total is $530, 1.1% above the 30-day average of $524. The average offer price across 2 retailers is $614 (15.9% above the cheapest). Price volatility is moderate (7.3% CV).
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.
Core Ultra 9 285K socket, memory & cooler compatibility
| TDP | 250 W |
| Cores / threads | 24C / 24T |
| Socket | LGA 1851 |
| Memory support | DDR5 |
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 Ultra 9 285K, not an estimate. Source: TechPowerUp (CPU-only package power, measured). The nameplate TDP is 250 W — measured all-core draw is 235 W, which is exactly why we grade on measured watts, not the rating.
| Workload | Measured power | Work / watt | |
|---|---|---|---|
| In games (CPU-only) | 94 W | 10.8 pts/W | gaming work per watt |
| Sustained all-core (CPU-only) | 235 W | 8.1 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 Core Ultra 9 285K 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 Core Ultra 9 285K price & upgrade math (calculated)
We don't track live used-market listings yet, so here is an honest calculated guide instead. The cheapest new Core Ultra 9 285K in the 2026-09-11 offer frame is $530. Two yardsticks for a unit in excellent condition: 80% of the cheapest new price ≈ $424, and $234 — the price at which its Value Score reaches a perfect 100 in its strongest scenario (Code Builds). The lower of the two, ≈ $234, 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 Core Ultra 9 285K 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.
- Where can I buy the Core Ultra 9 285K?
- We track 3 offer(s) across stores, variants and conditions — the first 3 useful price highlights are shown above, which is the complete currently tracked set. Each row keeps its own checked date; always confirm the final price at the retailer.
- Is the Core Ultra 9 285K worth it in September 2026?
- That depends on your scenario: its Relative Value ranges across presets in the scenario matrix above (currently #54 of 235 in-stock by balanced value in the 2026-09-11 offer frame). Use the live calculator to weigh your own priorities.
- Is the Core Ultra 9 285K compatible with my motherboard?
- It uses LGA 1851 and supports DDR5. Confirm the exact CPU and required BIOS version on the motherboard vendor's support list before buying.
- What is the Core Ultra 9 285K best suited for?
- On our 1000-point CPU scale it scores 1893 multi-thread / 1102 single-thread / 1017 gaming. The scenario matrix separates gaming, productivity and efficiency.
- What is a fair used price for the Core Ultra 9 285K?
- We don't have live used-market data yet, so we calculate a guide: 80% of the cheapest new offer (≈$424) or the price where its Value Score reaches 100 in its strongest scenario ($234) — whichever is lower, ≈ $234 for a unit in excellent condition. Discount for wear, mining history or a missing warranty.
- Is a used Core Ultra 9 285K worth it?
- A used or refurbished Core Ultra 9 285K can undercut new pricing meaningfully — see the New / Refurbished / Used split in the offers table and our calculated used ceiling of ≈$234. Weigh the discount against no manufacturer warranty and seller risk; paste any listing into the calculator to score it against the current market.

Strong if / think twice if
Strong if
- •Strong multi-thread index for heavy productivity and compile workloads
- •Modern platform I/O (Thunderbolt, fast memory support)
- •Sometimes discounts into genuinely competitive value territory
Think twice if
- •Gaming index clearly behind X3D chips at typical prices
- •Higher package power under sustained load
- •New socket generation risk for long-term upgrades
