Conclusion

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]

In terms of raw single-core performance the flagship AMD FX-8350 is lagging behind intel's processor line-up by over two generations. The PassMark Single Thread scores for the i5-2500K vs the FX-8350 are 1863 to 1520 which shows that in terms of raw per-core processing the FX-8350 is lagging the two year old i5 by 23%. Where the AMD FX makes up is on multi-core performance, with a score of 9156 vs 6745, the AMD leads the Intel 2500K by 36% making it the far more capable multi-threaded server orientated performer. The 8350 is also cheaper but significantly more power hungry which counts strongly against it as a server proposition. The FX-8350 could be a good fit for specific server use cases but for general consumer use, which is single and dual core intensive, Intel's two year old i5-2500K delivers better performance. [May '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.
