Performance Compared

Productivity

Intel Core i5-10400FBest75

Handles everyday applications and multitasking efficiently.

Intel Core i5-4670K45

Sufficient for basic office work, but the lack of Hyper-Threading means multi-threaded productivity workloads complete much slower than on modern CPUs.

Gaming

Intel Core i5-10400FBest85

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

Intel Core i5-4670K55

Adequate for older or esports titles at 1080p, but struggles significantly with modern CPU-demanding games due to having only four threads.

Virtualization

Intel Core i5-10400FBest70

Capable of running basic virtual machines.

Intel Core i5-4670K35

Four threads are a hard constraint for virtualization, and the lack of VT-d on this K-series part limits IOMMU passthrough capabilities.

Efficiency

Intel Core i5-10400FBest65

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

Intel Core i5-4670K40

The 22nm Haswell architecture draws notably more power under load than modern alternatives, and temperatures spike easily due to the internal thermal paste.

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.

Read the full review

The i5-4670K was a capable quad-core in its day, but its notorious thermal issues under the IHS severely limited overclocking headroom, making it a historical footnote compared to the refreshed 4690K.

Best for: Repairing an existing LGA 1150 system where a motherboard swap is impractical and delidding is not a concern.
