CPU Comparison
Intel Core i7-8670T vs Intel Core i7-8700B
A side-by-side comparison of specs, performance and value. The Intel Core i7-8670T is a low-power desktop processor engineered for small form factor PCs, AIO systems, and space-constrained environments where thermal dissipation is limited. Belonging to the 8th Gen Coffee Lake family, it distinguishes itself with a 35-watt thermal design power, significantly lower than standard desktop chips. Despite its power-saving orientation, it boasts six cores and twelve threads, delivering robust multitasking capabilities. The processor operates at a base frequency of 2.3 GHz and can boost up to 3.7 GHz, ensuring responsive performance for both everyday computing and demanding applications. Integrated UHD Graphics 630 allow it to handle basic display tasks without a discrete GPU, making it ideal for compact office machines. This low-TDP approach allows system builders to create quieter, cooler, and more energy-efficient desktops without heavily sacrificing the core count and multi-threaded performance necessary for modern productivity workloads and moderate content creation. Its ability to fit into Mini-ITX cases with minimal cooling requirements makes it a favorite for HTPC builders and corporate environments prioritizing energy savings.
