The CPU itself is INCREDIBLY slow and awful to run pretty much anything with. However, it does have one thing definitely going for it. Despite me having used it pretty much 24/7 for the past 7 years, and the SFF Optiplex 760 it's on, having only been cleaned 3-4 times in its' whole life, because I didn't know how to clean a PC until fairly recently. Yet the E5300 STILL runs after all these years, and only begun getting any noticeably slower in the past year or so. This kind of reliability is far more than what I can say for Intel's high end CPUs from just the past year. Because half a year ago I finally managed to get a new computer to replace my Optiplex. And so far I've somehow lost TWO CPUs in a row. First the original i5-11400f I had bought, and then the i5-11500 I bought as a replacement. [Feb '22 5555]

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 popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
