CPU Comparison
Intel Core i7-8670 vs Intel Core Ultra 5 125HL
A side-by-side comparison of specs, performance and value. The Intel Core i7-8670 is a mainstream desktop processor designed to deliver balanced performance for both gaming and productivity. As part of the 8th Gen Coffee Lake family, it features six cores and twelve threads, a significant upgrade over the previous generation's quad-core i7 designs. Operating at a base frequency of 3.1 GHz and boosting up to 4.4 GHz, it offers snappy single-threaded performance and solid multi-threaded capabilities. With a standard 65-watt TDP, it strikes an excellent balance between power consumption and heat generation, making it compatible with a wide range of affordable coolers. The inclusion of Intel UHD Graphics 630 allows for basic display functionality without a discrete GPU, though serious gamers and creators will want to pair it with a dedicated graphics card. This processor is tailored for users who demand reliable hexa-core performance for everyday tasks, moderate content creation, and a smooth 60 FPS gaming experience without paying a premium for the highest clock speeds.
