Conclusion 
Average Bench 80.5%
Average Bench 71.4%

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]

 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.
