Conclusion

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 8 core, 16 thread 2700X is AMD’s second generation Ryzen 7 flagship following in the wake of the Ryzen 7 1800X which continues to offer excellent multi-core value for money. This new Pinnacle Ridge processor features the Zen+ architecture with 12nm lithography compared to 14nm previously. Whilst there is no increase in the number of cores, the stock base / boost clocks appear to have received a bump up to 3.7 / 4.3 GHz from 3.6 / 4.0 GHz. The 2700X is compatible with both the new 400 series and 300 series of motherboards. Early benchmarks indicate that the 2700X has a slightly greater effective speed than the 1800X, although further benchmarks are necessary to quantify this. The expected launch price of $329 includes a Wraith Prism cooler and is in the same price bracket as the 1800X and Intel’s Coffee Lake i7-8700K. Whilst the 6 core, 12 thread 8700K beats the 2700X in single and quad core performance by around 15%, the 2700X wins on multi-core workloads. PC gaming and desktop performance is generally governed by six or less cores but the 2700X offers value for money to workstation users. Even though the 2700X excels at video production, streamers should look elsewhere. Streaming with dedicated hardware such as NVENC or a separate stream PC will nearly always result in fewer dropped frames. [Apr '18 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 the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
