Frequently Asked Questions

What does the T suffix mean on Core i5-14400T?

The T suffix indicates a low-power thermally optimized variant with reduced TDP (35W vs 65W base). It has a lower base frequency but the same core count as the standard i5-14400.

Is the i5-14400T suitable for gaming?

The i5-14400T can handle gaming workloads but its lower base frequency and TDP limit sustained performance compared to the standard i5-14400. It is best suited for light gaming in compact systems.

What is the difference between i5-14400T and i5-14400?

The i5-14400T has a 35W TDP and 1.5GHz base frequency while the i5-14400 has a 65W TDP and 2.5GHz base frequency. Both have 10 cores and integrated UHD Graphics 730.

The Intel Core i5-14400T delivers 10 cores at 1.5GHz with 20MB L3 cache on LGA1700 — the low-power T variant of the 14th Gen Core i5 for compact SFF systems and thermally constrained environments.
