The Intel i7-4500U is a dual core, four thread 4th generation Haswell ultrabook processor. Its most impressive feature is a TDP of 15 Watts which typically yields over five hours of battery life. Despite the i7-4500Us relatively low effective speed of 66 (compared to the average of the leaders), the i7-4500U is perfectly adequate for handling the majority of day to day computing tasks, but it will struggle to deliver on CPU intensive tasks such as video editing and CAD. Gamers should obviously look elsewhere as despite the impressive desktop performance of the integrated HD 4400 graphics, 3D performance is far from adequate for modern games. If the battery life is a priority, then downgrading to the cheaper i5-4200U will deliver 15% more life but comparing the 4500U and 4200U shows that the 4500U is around 17% faster. [Nov '14 CPUPro]


Processor Rankings (Price vs Performance) January 2018 CPU Rankings.

Welcome to our desktop CPU comparison. We calculate effective speed which measures real world performance for typical consumers. Effective speed is adjusted by price to yield a value for money rating which is geared towards gamers. Calculated values don't always paint the whole picture so we check them against hundreds of individual user ratings. The customizable table below combines these factors and more to bring you the definitive list of top CPUs. [CPUPro]
