Conclusion 
Average Bench 40.3%
Average Bench 85.2%

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]

The i5-10400F is a six-core hyperthreaded CPU from Intel’s latest Comet Lake series of desktop processors. This 65 W CPU has single core and all core boost frequencies of 4.3 GHz and 4.0 GHz, respectively. Whilst the 10400F will require a new LGA1200 motherboard, such as the Z490, Intel have guaranteed that the next generation of Rocket Lake CPUs will also be compatible with this chipset. The 10400F is aimed at mid-tier gaming PC builds, and as such, ships with a cooler but without integrated graphics. Despite being officially launched in Q2 of 2020, at the time of writing, the 10400F is still not widely available. Compared to the similarly priced Ryzen 5 3600, the 10400F’s lower memory latency gives it the lead in gaming and effective speed benchmarks. Since the Ryzen architecture creates a gaming bottleneck, it is necessary to upgrade to a higher tier, Intel CPU for better gaming performance. On the other hand comparing the i5-10400F and the i3-10100 shows that the 10100 offers comparable gaming performance for 22% less money whilst also including integrated graphics. [Jun '20 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.
