The Intel i7-4771 is the same as the i7-4770 apart from a 100 MHz increase in base clock from 3.4 GHz to 3.5 GHz. In theory this increase will only impact multi-core workloads because both processors have the same turbo clock of 3.9 GHz which should be engaged during single and dual core workloads. On multi-core workloads the turbo needs to be disabled in order to maintain acceptable core temperatures and operating frequencies drop to base clock where the i7-4771 has a marginal 100 MHz or 2.9% advantage. In other words the two processors should be largely identical. Looking at the i7-4770 vs the i7-4771 benchmarks verifies this. Both the 4770 and 4771 are the current top end mainstream market leaders but for the vast majority of desktop users they are probably overkill as typical consumer use rarely requires more than two cores. [Mar '14 CPUPro]

The Intel Core i3-4340 is a budget dual-core four threaded 4th generation Haswell processor released in Q3 2013. At the time of release it was the top end Haswell Core i3 chip – offering great value for money, performance and power efficiency. It scores a strong effective speed of 89% with its base clock of 3.6 GHz which means that users will experience smooth and fast performance with the majority of desktop applications. Its two cores and four virtual cores are adequate for most games. The i3-4340 features Intel HD Graphics 4600 which are probably okay for playing some older games in 720p and are comparable AMD integrated graphics (for example, on the AMD A10-5800k) when it comes to 3D gaming. But serious gamers will need to have enough money left over after purchasing the i3-4340 to spend on a stand alone GPU. [Nov '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.
