Superseded by the faster 10th Gen 10750H [Apr '20 CPUPro]

MORE DETAILS

The Intel Core 2 Duo E8400 is amongst the fastest of the Core 2 Duo range of now nearly ten year old CPUs. The E8400 is included in our group tests simply as a reference point due to its huge success back in its day. Running at a clock speed of 3.0 GHz the E8400 has an effective speed of 52 which is 85% slower than its modern day counterparts. The relative lack of performance is especially noticeable in the area of multi-core processing as a consequence of the E8400's relatively few two cores. Anyone considering an upgrade needn't hesitate as modern CPUs are not only orders of magnitude faster but also considerably more energy efficient and feature packed. [Oct '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 the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
