This article covers intel 第14世代 CPU Core i9-14900KF (アンロック版・GPU機能なし) 24コア.

Overview

The Intel Core i9-14900KF is the flagship unlocked desktop CPU in Intel's 14th-generation lineup, built around 24 cores and 32 threads with a max turbo of 6.0 GHz on its P-cores. The "KF" suffix means there is no integrated graphics, so a dedicated GPU is mandatory. It fits the LGA1700 platform and works with both DDR4 and DDR5 memory, which makes it a flexible upgrade option for existing builds. This is a no-compromise part for high-refresh gaming, video editing, and heavy multitasking.
Market positioning is firmly high-end. This model belongs to the Raptor Lake Refresh generation, raising clocks on the established 13th-generation architecture rather than introducing a new core design. Consequently, the experience you get depends heavily on the motherboard, cooling, and graphics card around it.
Given its 125W base and 253W turbo power envelope, buyers need a robust cooler and a full-size power supply. Most practical builds will pair it with a Z790 board, DDR5 memory, and an 850W-plus PSU. If that sounds like a lot of system, it is — this CPU exists for users who genuinely need top-tier throughput.

Compatibility Guide

  • Socket: LGA1700. Compatible with Intel 600/700 series chipsets; 600-series boards may require a BIOS update for 14th-gen support.
  • Memory: Supports DDR4-3200 and DDR5-5600, but each motherboard supports only one of the two standards.
  • No iGPU: there is no display output without a dedicated graphics card.
  • Power: recommend 850W or higher for a full system; 1000W-class is safer when pairing with high-end GPUs.
  • Cooling: a 360mm liquid cooler or equivalent high-end air cooler is recommended for sustained 253W turbo loads.
    When building from scratch, a Z790 motherboard with dual 8-pin EPS connectors gives you the most stable power delivery for overclocking. If you are reusing an older 600-series board, check the manufacturer's CPU support list and update the BIOS before installing this chip.

Product Info

The Core i9-14900KF launched in October 2023 as part of the Raptor Lake Refresh lineup. The Japanese retail box version carries the model code BX8071514900KF, with a street price of about ￥85,280 as of September 2026. The box contains the CPU and a quick start guide only; no cooler is included.
Key specifications include a P-core base clock of 3.2 GHz and a maximum turbo of 6.0 GHz, E-cores running at 2.4 GHz base and 4.4 GHz turbo, 32MB of L2 cache, 36MB of L3 cache, and a TDP of 125W base / 253W max. The multiplier is unlocked, so Z-series motherboards allow additional tuning beyond stock settings.
The market position is clearly high-end flagship. This is the processor to choose when you want one part that can handle demanding games, encoding jobs, and complex multitasking without compromise. For light office work or casual gaming, it is far more than most users need.

Best Use Cases

  • High-refresh-rate gamers: the 6.0GHz P-cores help maintain stable frame rates in CPU-heavy shooters and racing games. Since there is no integrated GPU, you must pair it with a graphics card that matches your resolution and refresh target. If your budget is GPU-first, a lower-tier CPU may serve you better.
  • Video editors and 3D artists: 24 cores and 32 threads accelerate rendering, encoding, and preview-heavy workflows. If your work is mostly light photo editing that relies on single-thread speed, you may not feel the difference from cheaper models.
  • Buyers building a long-term high-end desktop: the combination of high clocks, DDR4/DDR5 support, and unmatched thread count makes it a sensible foundation for a machine you plan to keep for years. Those planning a small-form-factor build should look elsewhere due to heat and power constraints.

Things to Consider

The biggest caveats are heat and power draw. The 253W maximum turbo figure demands both a strong cooler and a power supply with real headroom. Because the "KF" suffix removes integrated graphics, there is also an unavoidable extra cost for a discrete GPU.
For gaming-only builds, overspending on this CPU can actually reduce overall performance if it forces you to step down the graphics card. At high resolutions, GPU capacity usually matters more. Also keep in mind that the LGA1700 platform is transitioning, so future upgrade paths may require a new motherboard rather than a simple CPU swap.
Finally, consider acoustics. In a case with limited airflow or in a quiet-focused setup, even a large cooler may produce noticeable fan noise when the CPU is running at full turbo. Plan your cooling and case airflow before committing to this processor.

FAQ

Q: Can I get video output without a graphics card?
A: No. The Core i9-14900KF has no integrated GPU, so the motherboard's display outputs will not work. You must install a dedicated graphics card.
Q: Will it work with a DDR4 motherboard?
A: Yes. The CPU supports both DDR4 and DDR5, but a given motherboard supports on
