The Intel Core i7-7700T is a low-power desktop processor launched in January 2017 as part of the 7th Generation Kaby Lake family. Designed for small form factor (SFF) PCs and all-in-one systems, it operates at a highly efficient 35-watt TDP. Built on Intel's 14nm process, it features 4 cores and 8 threads. The processor runs at a base clock of 2.9 GHz and can boost up to 3.8 GHz using Intel Turbo Boost 2.0. It includes 8MB of L3 cache and integrates Intel HD Graphics 630, which supports hardware-accelerated media playback and basic gaming. 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 its 'K' series sibling, the i7-7700T remains a reliable choice for office workstations, HTPCs, and compact builds where space and power are constrained.
The Intel Core i7-7700T is a 7th Gen Kaby Lake processor featuring 4 cores and 8 threads. With a 35W TDP and a boost clock of 3.8 GHz, it offers a great balance of performance and efficiency.
It is ideal for small form factor PCs, HTPCs, and office workstations where cooling and power are constrained.

Architecture Overview
The Core i7-7700T utilizes the Kaby Lake microarchitecture, which is an optimization of the Skylake architecture, manufactured on Intel's refined 14nm process. The defining characteristic of the 'T' series is its strict 35-watt thermal design power (TDP), a significant reduction from the 65W of standard desktop models. The architecture features 4 cores and 8 threads via Hyper-Threading. To fit the 35W envelope, the base clock is reduced to 2.9 GHz, though it can boost up to 3.8 GHz under lighter loads. The architecture includes 8MB of L3 cache and supports dual-channel DDR4 memory at 2400 MT/s. The integrated Intel HD Graphics 630 features 24 execution units and supports advanced video codecs, including HEVC 10-bit decode/encode. The architecture also includes Intel Speed Shift technology for faster frequency transitions. By optimizing the 14nm process, Kaby Lake allowed for slightly higher clock speeds and better power efficiency at lower TDPs compared to Skylake, making it ideal for compact systems.

History
Launched on January 3rd, 2017, the Intel Core i7-7700T was part of the 7th Generation Kaby Lake desktop family. This release was an optimization of the Skylake architecture, focusing on higher clock speeds and refined 14nm yields rather than architectural changes. The 'T' series was specifically designed for the growing small form factor (SFF) and all-in-one (AIO) markets, where thermal constraints made standard 65W processors impractical.
By offering a 35W TDP, the i7-7700T allowed manufacturers to build slim, quiet, and energy-efficient systems without sacrificing quad-core performance. It was widely adopted in business environments and home theater PC builds. However, the Kaby Lake generation is often remembered as a period of stagnation for Intel, as AMD's Ryzen architecture launched shortly after, forcing Intel to rethink its core count strategies.
Today, the 7700T is considered end-of-life but remains a reliable component for basic, low-power computing tasks.
Improvements over Previous Generation
- Higher boost clocks
- Better 14nm process yields
- Improved media engine

Should You Buy It?
Recommended for the right buyer
If you are considering the Intel Core i7-7700T today, it should only be for specific budget or replacement scenarios. It is an excellent choice if you are building a small form factor PC for basic office work, web browsing, or as a home theater PC, where its 35W TDP allows for silent or fanless operation. However, for new builds, modern processors offer significantly better performance and efficiency. The 7700T 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. It is a solid, reliable chip for basic computing needs in constrained environments.
Avoid if…
- You are building a new gaming PC
- You need an upgrade path
- You require high multi-threaded performance
