Intel Core i9-9920X / 9940X / 9960X / 9980XE / 9990XE – Wholesale CPUs Grade A Refurbished Tray Packaging

  1. Core i9-9990XE (Special Edition)

    • Unique 14-core part with 4.0 GHz base clock (highest in X-series)

    • 5.1 GHz max turbo (best single-thread performance)

    • 255W TDP requires specialized cooling

    • OEM-only product, not retail

  2. Core Count Progression

    • 12c/24t (9920X) → 14c/28t (9940X) → 16c/32t (9960X) → 18c/36t (9980XE)

    • More cores = lower base clocks but better multi-threaded performance

  3. Cache Scaling

    • L3 cache increases with core count (19.25MB → 24.75MB)

  4. Power Considerations

    • All models except 9990XE use 165W TDP

    • 9990XE’s 255W TDP reflects its extreme clock speeds
