Name: Intel Core i5-14400F
Brand: Intel
SKU: 9595

Manufacturer: Intel

The Intel Core i5-14400F is a desktop processor built for the LGA 1700 platform, targeting mainstream systems that pair well with a discrete graphics card, since this chip carries no integrated GPU. It uses Intel's hybrid core architecture, combining performance and efficiency cores under big.LITTLE technology, with a total of 16 threads spread across its 10-core layout. Compatible chipsets span a wide range, from entry-level H610 boards up through the enthusiast-oriented Z790, giving builders flexibility in platform choice.

On the memory side, the i5-14400F supports DDR5 at up to 4800 MHz across dual channels, with a maximum capacity of 192GB and peak bandwidth of 76.8 GB/s, along with ECC memory support. Cache is handled by 9.5MB of L2 and 20MB of L3. The chip runs at a base configuration of 6 cores at 2.5GHz and 4 efficiency cores at 1.8GHz, boosting up to 4.7GHz via Turbo Boost 2.0, while operating within a 100°C thermal limit. Instruction set support includes AVX2, AES, FMA3, and SSE 4.2, among others, and the processor connects to the platform via PCIe 5.0.

Pros

Supports DDR5 memory with a maximum speed of 4800 MHz and up to 192GB capacity, offering substantial headroom for memory-intensive workloads
ECC memory support adds a layer of data reliability useful in workstation or professional environments
Compatible with a wide range of chipsets from H610 to Z790, providing flexibility across different platform tiers
PCIe 5.0 support enables compatibility with the latest storage and expansion hardware
Hybrid core architecture with 10 cores and 16 threads allows the processor to distribute workloads across performance and efficiency cores
NX bit support provides a hardware-level security measure against certain types of memory-based exploits

Cons

No integrated graphics, requiring a dedicated GPU in every build configuration
The multiplier is locked, ruling out any manual CPU overclocking
Turbo Boost is limited to version 2.0, an older iteration of Intel's frequency scaling technology
Single-core PassMark score of 3,709 reflects moderate single-threaded throughput for the platform

Who is this for?

This processor is a solid fit for users building a capable desktop workstation who plan to pair it with a dedicated graphics card. Its 10-core hybrid architecture with 16 threads handles multitasking and moderately threaded workloads without issue, while DDR5 support with up to 192GB of RAM and ECC compatibility makes it a reasonable choice for professional or content-creation environments where memory capacity and reliability matter. The broad chipset compatibility also suits builders who want flexibility when selecting a motherboard across different feature tiers, from budget H610 boards to full-featured Z790 platforms.

Who is this NOT for?

This chip is not well-suited for users who need integrated graphics, whether for a compact home theater PC, a budget build without a GPU, or any system where a discrete card is impractical. Enthusiasts who want to push performance through manual overclocking will also find this processor limiting, as the multiplier is locked and clock adjustments are off the table. Additionally, users who prioritize strong single-threaded workloads — such as certain legacy software or latency-sensitive applications — may find the single-core throughput figures moderate given the platform.
