Conclusion 
Average Bench 61.3%
Average Bench 54%

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 AMD Phenom II X6 1055T was the second in a long line of X6's, each successive revision received a small clock speed boost. The 1055T was clocked at 2.8 GHz base and 3.3 GHz turbo. The 1100T was the fastest X6 and has a base/turbo clock of 3.3/3.7 GHz. Comparing the 1055T and 1100T shows that the two processors have a very similar performance profile, both excelling at multi-core workloads and both showing relative weakness in single, and dual-core workloads. In todays market the bar has been raised several notches especially for single and dual core workloads but the 1055T still puts in a relatively strong multi-core performance which is roughly on a par with an Ivy Bridge i5-3570K. [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 popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
