Performance Compared

Productivity

Intel Core i5-10400F75

Handles everyday applications and multitasking efficiently.

Intel Core i3-10105F

Handles standard office work and web browsing fine, but the lack of an iGPU means no hardware video encoding acceleration for quick sync.

Gaming

Intel Core i5-10400F85

Excellent 1080p gaming performance when paired with a mid-range GPU.

Intel Core i3-10105F

When paired with a mid-range GPU, it delivers smooth eSports performance and playable 1080p experience in older AAA titles, though modern heavy games will be CPU-limited.

Virtualization

Intel Core i5-10400F70

Capable of running basic virtual machines.

Intel Core i3-10105F

Same 8-thread virtualization capability as the 10105, adequate for a single light VM.

Efficiency

Intel Core i5-10400F65

Standard 14nm efficiency, adequate for a 65W TDP.

Intel Core i3-10105F

Efficiency is comparable to the 10105; the disabled iGPU saves a negligible amount of power under load.

Our Verdict on Each

By removing the integrated graphics, Intel created a highly affordable 6-core CPU that maximizes value for gamers who already own a discrete GPU.

Best for: The Intel Core i5-10400F is highly recommended for budget-conscious gamers building a 1080p system with a dedicated graphics card. By cutting out the integrated graphics, it saves money that can be better spent on a stronger GPU, making it an ideal pairing for cards like the GTX 1660 Super or RTX 3060. Its 6-core, 12-thread design ensures it won't bottleneck mid-range GPUs in most modern games. Because it is locked, you don't need to spend extra on Z-series motherboards or fancy coolers; a B460 board and stock cooling are perfectly adequate. It is perfect for students or first-time builders who want a reliable, plug-and-play experience. Avoid it only if you absolutely need integrated graphics as a fallback or if you plan on overclocking.

An exceptional value proposition in its time, stripping the iGPU to offer the cheapest entry point into dedicated gaming on the LGA 1200 platform, though now overshadowed by newer architectures.

Best for: Finding one used for under $30 to revive an old LGA 1200 gaming rig or complete a ultra-low-budget build with spare parts.
