CPU Comparison
Core i7-7700 vs Intel Core i5-7600K
A side-by-side comparison of specs, performance and value. The Intel Core i7-7700 is a mainstream desktop processor launched in early 2017 as part of the Kaby Lake lineup. Designed for the LGA 1151 socket, this 14nm quad-core CPU features Hyper-Threading, allowing it to process 8 threads simultaneously. Operating at a base frequency of 3.6 GHz and boosting up to 4.2 GHz, it delivered excellent single-threaded performance for its time, making it a popular choice for gamers and general consumers. With a 65W TDP, it is highly power-efficient and easy to cool, often running adequately on the stock cooler. The processor includes 8MB of L3 cache and supports dual-channel DDR4-2400 memory. It also features Intel HD Graphics 630, providing competent display outputs and hardware video decoding for systems without a dedicated GPU. While it has been superseded by modern architectures, the i7-7700 remains a capable chip for budget builds and legacy system upgrades.
