Conclusion 
Average Bench 71.4%
Average Bench 73.6%

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]

MORE DETAILS

The Core i7-4770K is Intel's fourth generation (codename Haswell) flagship processor in the hugely successful Core range. It's not surprising that the 4770K sets a new Real World Performance index record, besting its predecessor by just over 9%. The 4770K also tops out in the remainder of our benchmarks setting new highs of 10020 and 2164 in the PassMark and PassMark Single Thread tests which equates to roughly an 8% overall performance increase over the 3770K. With a TDP of 84 watts, power consumption has increased slightly over the 3770K. The new Core i7-4770K demonstrates around an 8% performance increase over its predecessor the 3770K but it costs 12% more. As a result, at least until prices drop, this processor represents marginally worse value for money than the 3770K. [Jun '13 CPUPro]

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
