CPU Comparison
Intel Core i5-7400T vs Intel Core i5-7600K
A side-by-side comparison of specs, performance and value. The Intel Core i5-7400T is a low-power quad-core desktop processor from Intel's 7th Generation Kaby Lake lineup. Designed for small form factor (SFF) PCs, mini-PCs, and AIO systems, it operates with a strict 35W TDP. Unlike standard desktop processors, it lacks Hyper-Threading, featuring 4 cores and 4 threads. It operates at a base clock of 2.4 GHz and boosts up to 3.0 GHz, providing adequate performance for everyday office tasks, web browsing, and media consumption. With 6MB of L3 cache, it efficiently handles bursty workloads. The integrated Intel HD 630 graphics support 4K video playback and basic display outputs, making it suitable for HTPC (Home Theater PC) builds. While its performance is limited by the lack of Hyper-Threading and low clocks, its low power consumption allows for fanless or quiet cooling solutions, making it an ideal choice for space-constrained environments where silence and efficiency are prioritized over raw computing power.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Good for office suites, but 4 threads limit heavy multitasking.
Snappy for daily tasks but fails in multi-threaded rendering.
Gaming
Not suitable for modern gaming; HD 630 is too weak.
High clocks help older games, but 4 threads cause severe stuttering in modern titles.
Virtualization
Lacks Hyper-Threading, making it poor for running multiple VMs.
Poor for VMs due to lack of threads.
Efficiency
Excellent power efficiency with a strict 35W TDP.
91W TDP increases significantly when overclocked.
