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]

MORE DETAILS

The Intel Core i5-3470 is a relatively fast quad core desktop processor based on the 3rd generation Ivy Bridge architecture which was launched in Q2 2012. It scores a good effective speed of 87 (max turbo frequency of 3.6 Ghz). Unlike the ‘K’ model processors, the i5-3470 doesn't have an unlocked multiplier, so the max overclocked frequency is not much beyond its stock frequency. The i5-3470 features integrated Intel HD Graphics 2500 which are relatively weak by modern standards, so to enjoy a good 3D gaming experience a GPU upgrade is necessary. Whilst the 3470 is a reasonable CPU, it's only fractionally cheaper than the i5-3570K which scores an effective speed of 98 and has an unlocked multiplier. Overall the 3470 is somewhat dated and there is far better value available in today's market[Nov '14 CPUPro]

 Frequently Asked Questions

 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.
