CPU Comparison
Intel Core i5-7400 vs Intel Core i5-7400T
A side-by-side comparison of specs, performance and value. The Intel Core i5-7400 is a mainstream desktop processor launched in early 2017 as part of the 7th Generation Kaby Lake lineup. Designed as the entry point for the Core i5 desktop family, it features four physical cores operating at a base frequency of 3.0 GHz, with the ability to boost up to 3.5 GHz. Manufactured on Intel's mature 14nm process, it fits into the standard 65-watt TDP envelope, making it compatible with a wide range of cooling solutions and motherboards. The chip lacks Hyper-Threading, handling four threads simultaneously, which was standard for i5 processors of this generation. It integrates Intel HD 630 graphics, providing adequate performance for everyday multimedia tasks and hardware-accelerated video decoding. Supporting dual-channel DDR4 memory at 2400 MT/s and featuring 16 PCIe 3.0 lanes, the i5-7400 was widely adopted in budget gaming rigs and office PCs. While it has been surpassed by modern processors, it remains a functional solution for basic computing needs and legacy system builds.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Solid performance for standard office tasks, but limited by 4 threads in heavy multitasking.
Good for office suites, but 4 threads limit heavy multitasking.
Gaming
Can run older games well but will bottleneck modern GPUs significantly.
Not suitable for modern gaming; HD 630 is too weak.
Virtualization
Basic VM support is possible, but performance is restricted by core count.
Lacks Hyper-Threading, making it poor for running multiple VMs.
Efficiency
65W TDP is well-managed and easy to cool.
Excellent power efficiency with a strict 35W TDP.
Specialized Performance
AI / ML
