The Intel Core i7-920 is five and a half years old which puts it at an enormous disadvantage to more modern processors. The 920 sports four cores and eight threads which is the same basic configuration that Intel still uses in the majority of their i7s. Comparing the 920 to the 4770K, its modern day equivalent, shows that 920 lags by 63% at stock speeds and by 44% when both processors are overclocked. Overclocking improves the 920 by 30% vs just 17% for the 4770K. Aside from approximately 50% more calculation throughput the 4770K offers lower power consumption, compatibility with Intel's latest FCLGA1150 platform, on-board graphics and newer CPU instructions. Owners of the 920 should probably consider upgrading not only to improve system response times but also to take advantage of the newer platform. [Mar '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.
