CPU Comparison

Intel Core i7-4790T vs Intel Core i7-6700T

A side-by-side comparison of specs, performance and value. The Intel Core i7-4790T is a low-power desktop processor launched in May 2014 as part of the 4th Generation Haswell refresh. Designed for small form factor (SFF) PCs and all-in-one systems, it operates at a highly efficient 45-watt TDP. Built on the 22nm process, it features 4 cores and 8 threads. The processor runs at a base clock of 2.7 GHz and can boost up to 3.9 GHz. It includes 8MB of L3 cache and integrates Intel HD Graphics 4600. The 'T' suffix denotes its low-power nature, trading raw multi-core frequency for energy efficiency and cooler operation. This allows it to be used in compact chassis with minimal cooling requirements. While it lacks the unlocked multiplier of the 'K' series, the i7-4790T remains a reliable choice for office workstations, HTPCs, and compact builds where space and power are constrained.

Our Verdict on Each

A highly efficient 45W desktop CPU for its time, but its low base clock makes it sluggish for modern tasks.

Best for: If you are considering the Intel Core i7-4790T today, it should only be for specific budget or replacement scenarios. It is an excellent choice if you are maintaining a small form factor PC for basic office work or as a home theater PC, where its 45W TDP allows for silent operation. However, for new builds, modern processors offer significantly better performance and efficiency. The 4790T is best purchased used or refurbished at a low price. Avoid this processor if you need to do any modern gaming, heavy video editing, or if you want an upgrade path, as the LGA 1151 socket is obsolete.
