Intel Core i5-11400 vs Intel Core i5-11400T: comparison
Comparison of Intel Core i5-11400 and Intel Core i5-11400T: key differences and a full specification table.
Key differences
Intel Core i5-11400 has a higher base clock (2.6 GHz vs 1.3 GHz), a higher maximum clock (4.4 GHz vs 3.7 GHz) and a higher maximum integrated graphics clock (1.3 GHz vs 1.2 GHz).
At the same time, Intel Core i5-11400T has a lower TDP (35 W vs 65 W).
Both processors match on: core count (6), thread count (12), L3 cache (12 MB), process node (14 nm), maximum memory size (128 GB), memory channels (2), PCIe version (4).
These are specification values: they show differences between the models but do not determine a performance winner. For a specific workload, rely on independent benchmarks.
