Our Verdict on Each

A solid 2014 CPU that still handles basic tasks, but struggles with modern workloads and lacks Windows 11 support.

Best for: The Core i7-4790 is a processor that should only be encountered in legacy systems. If you already own a motherboard with this chip, it can still serve adequately for basic web browsing, office applications, and older games. However, it is not recommended for purchase today. The LGA 1150 platform is dead, meaning there is no upgrade path. Additionally, the lack of official Windows 11 support and high 84W TDP make it inefficient compared to modern budget processors. Avoid buying this CPU for new builds. It is best utilized by keeping existing hardware alive for light duties.

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if you need to do any modern gaming, heavy video editing, or if you want an upgrade path, as the LGA 1151 socket is obsolete.
