10th Gen Intel Core i5 10400F Review

The 10th Gen Intel Core i5 10400F is a 6-core, 12-thread desktop processor without integrated graphics, running a 2.9 GHz base clock that boosts to 4.3 GHz within a 65 Watt TDP on the LGA 1200 socket.

The "F" suffix drops integrated graphics entirely to reach a lower price point, a sensible trade-off for budget builders who already have a discrete GPU and don't need the iGPU fallback the standard 10400 includes.

Integrated Graphics

This F-suffix variant ships without a functional integrated GPU; a discrete graphics card is required for display output, in exchange for a lower price than the standard 10400.

How Is the Core i5 10400F in Terms of Performance

The 6-core, 12-thread layout delivers genuinely solid mainstream desktop performance for gaming and everyday productivity, with the missing iGPU being a non-issue for the many budget builders who already own a discrete GPU.

Plays back and exports 4K and 8K timelines across several camera codecs, with effects and multi-stream sequences, in Adobe Premiere Pro.

Export time rewards more cores, but much of the timeline work runs on the hardware decoder and the graphics card instead of the processor. A small gap here rarely changes how the edit feels.

Benchmarks

Cinebench R23 multi-core scores of 7,617 and single-core scores of 1,111 reflect solid mainstream 6-core Comet Lake performance. Geekbench 5 multi-core scores of 6,346 confirm competent everyday productivity and gaming capability for a budget-focused chip.
