CPU Comparison

Core i7-4600U vs Core i7-4650U

A side-by-side comparison of specs, performance and value. The Intel Core i7-4600U is an ultra-low voltage mobile processor launched in September 2013 as part of the 4th Generation Haswell lineup. Designed specifically for thin-and-light ultrabooks, this dual-core CPU features Hyper-Threading to handle 4 threads simultaneously. Operating at a base frequency of 2.1 GHz and boosting up to 3.3 GHz, it delivered strong single-threaded performance for its 15W thermal envelope. The processor is built on Intel's 22nm process and utilizes the BGA 1168 socket, meaning it is soldered directly to the motherboard. One of its standout features is the inclusion of Intel HD Graphics 5000, which offers significantly more execution units than standard HD 4600, providing better integrated graphics performance for light gaming and media workloads. With 4MB of L3 cache and support for DDR3 memory, the i7-4600U was a premium choice for business ultrabooks where battery life and compact dimensions were prioritized over raw multi-core horsepower.
