The Core i7-4790 is the third upgrade to Intel's flagship quad core hyper-threaded CPU. This version, like its predecessor the i7-4771, gets a 100 MHz bump in stock frequency and additionally the i7-4790 also gets a 100 MHz turbo frequency bump. These improvements (~4%) are marginal and practically impossible to discern in day to day use. Looking at a benchmark comparison between the 4771 and 4790 verifies that there is little difference between the two CPUs. Although the i7-4790 isn't much of a step forward, it's still one of the best (locked) mainstream processors on the market. AMD hasn't been able to compete with Intel on single threaded performance for several years, consequently Intel have no need to push the envelope. Overclockers should wait for the 4790K which is rumoured to be released shortly. [May '14 CPUPro]

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]
