Core i7-870S vs Core i7-875K

A side-by-side comparison of specs, performance and value. The Intel Core i7-870S is a low-power desktop processor launched in July 2010, based on the 45nm Lynnfield architecture. Designed as a premium, thermally efficient option for small form factor and all-in-one PCs, it operates at a base frequency of 2.666 GHz and boosts up to 3.6 GHz via Turbo Boost. The 'S' suffix indicates a reduced 82W TDP compared to the standard 95W i7-870. It features 4 cores and 8 threads, aided by an 8 MB L3 cache. Utilizing the LGA 1156 socket, it supports dual-channel DDR3 memory and integrates 16 PCIe 2.0 lanes. Like other Lynnfield chips, it lacks an integrated GPU, requiring discrete graphics. The 870S was a niche product, offering top-tier Lynnfield performance in a tighter thermal envelope. Although obsolete today, it represents Intel's ongoing efforts to segment high-end silicon for specific use cases where heat dissipation was a limiting factor.
