CPU Comparison
Core i7-4650U vs Intel Core i5-4350U
A side-by-side comparison of specs, performance and value. The Intel Core i7-4650U is an ultra-low voltage mobile processor launched in June 2013 as part of the initial Haswell rollout. Designed for premium ultrabooks, this 15W dual-core CPU features Hyper-Threading, allowing it to process 4 threads concurrently. It operates at a base frequency of 1.7 GHz and can boost up to 3.3 GHz, dynamically scaling its performance based on thermal headroom. Built on Intel's 22nm Tri-Gate process, it utilizes the BGA 1168 socket, soldering it directly to the motherboard. The chip includes 4MB of L3 cache and supports DDR3 memory. A key differentiator of this SKU is the inclusion of Intel HD Graphics 5000, which doubles the execution units compared to standard HD 4400 graphics, offering superior media processing and light gaming capabilities. The i7-4650U was targeted at business professionals and consumers needing a balance of high efficiency and snappy single-threaded responsiveness in extremely portable form factors.
The Bottom Line
Overview & Launch
