Core i7-5650U vs Intel Core i7-8559U
A side-by-side comparison of specs, performance and value. The Intel Core i7-5650U is a premium low-power mobile processor introduced in 2015, engineered for high-end ultrabooks where graphical prowess is valued alongside energy efficiency. Built on the 14nm Broadwell-U architecture, it features two cores and four threads, operating at a base clock of 2.2 GHz and boosting up to 3.2 GHz. The defining characteristic of the 5650U is its integration of Intel HD Graphics 6000, which offers 48 execution units, a significant upgrade over the standard HD 5500. This allows for smoother 4K video playback and better performance in graphically demanding applications. It includes 4 MB of L3 cache and maintains a 15-watt thermal design power, ensuring excellent battery life. Though end-of-life, the i7-5650U was a top-tier choice for premium mobile devices, offering a compelling blend of processing speed and enhanced integrated graphics for users constantly on the move indeed very truly.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Good for basic tasks, but dual-core limits heavy work.
High clock speeds ensure excellent performance in office and creative apps.
Gaming
HD 6000 is better than standard, but still weak for gaming.
Iris Plus 655 allows for playable frame rates in older or well-optimized games.
Virtualization
Not recommended for VMs.
Capable of running light VMs, though limited by 4 cores.
Efficiency
Good efficiency, though the larger GPU increases idle power slightly.
28W TDP is efficient enough for laptops but warmer than 15W parts.
