Conclusion 
Average Bench 49.8%
Average Bench 65.2%

A higher end Clarkdale hyperthreaded dual core processor. Came with similar amount of cores as i3-540 but comes with performance boosting features such as turbo which boost operating frequency to determined clock. For most users might worth looking to spend $30 more for more powerful i5-750 which comes with 4 core and 4 thread. Still worth it for today albeit for light gaming and modern basic tasks. [Dec '19 ColdSpy]

 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.
