Conclusion 
Average Bench 73.6%
Average Bench 73.5%

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]

MORE DETAILS

The Intel i7-4771 is the same as the i7-4770 apart from a 100 MHz increase in base clock from 3.4 GHz to 3.5 GHz. In theory this increase will only impact multi-core workloads because both processors have the same turbo clock of 3.9 GHz which should be engaged during single and dual core workloads. On multi-core workloads the turbo needs to be disabled in order to maintain acceptable core temperatures and operating frequencies drop to base clock where the i7-4771 has a marginal 100 MHz or 2.9% advantage. In other words the two processors should be largely identical. Looking at the i7-4770 vs the i7-4771 benchmarks verifies this. Both the 4770 and 4771 are the current top end mainstream market leaders but for the vast majority of desktop users they are probably overkill as typical consumer use rarely requires more than two cores. [Mar '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.
