The Intel i5-4440 is one of the cheaper four core Haswell processors. Unfortunately it is clocked at just 3.3 GHz Turbo, which is 15% lower than the leading Haswell i5 and because it has a locked multiplier there is little that can be done about it. Comparing the 4440 to the 4670K shows that the 15% reduction in Turbo clock speed basically results in a 23% performance loss to the 4670K. The Pentium G3420 actually has a higher base clock speed and costs about a third as much as the i5-4440 yet for the majority of, single and dual-core, desktop orientated tasks offers comparable performance. I don't think the i5-4440 makes much sense and would prefer either a much stronger 4770 or the weaker but much better value G3420. [Mar '14 CPUPro]

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 popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
