CPU Comparison

Intel Core i5-10210U vs Intel Core i5-10400H

A side-by-side comparison of specs, performance and value. The Intel Core i5-10210U is a quad-core mobile processor from Intel's 10th Generation Comet Lake lineup, designed primarily for thin-and-light laptops. Operating with a base frequency of 1.6 GHz and boosting up to 4.2 GHz, it utilizes Intel's trusted 14nm manufacturing process. With 8 threads and 6MB of L3 cache, it provides a balanced approach to everyday productivity, multitasking, and light content creation. While it lacks the advanced 10nm Sunny Cove architecture found in Intel's Ice Lake chips, the i5-10210U makes up for it with higher peak clock speeds and broad DDR4 and LPDDR3 memory support. This CPU is commonly found in mainstream business and consumer ultrabooks, offering reliable performance for office tasks, web browsing, and media consumption. Its 25W TDP ensures a good balance between battery life and thermal output, making it a practical choice for budget-conscious mobile users who need consistent multi-threaded capability without breaking the bank.
