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]

Below average average bench

The Intel Core2 Duo E8400 averaged 55.6% lower than the peak scores attained by the group leaders. This isn't a great result which indicates that there are much faster alternatives on the comparison list.

i've been using this processor nearly 5 years.It has not given me any problems till this day.Greatly works with gt 1030 .though it was a beast of once,but today more alternatives have been found such a g4560.From my opinion,it is okay for light gaming.Not made for high-end titles.

Not bad for basic use. Don't pair a good GPU with it though, it's just a dual-core after all.

Intel Core 2 Duo E8400(olso all e8...) is amazing CPU. It has 6MB L2 cash which makes it amazing. Also it's overclocking abilities are also crazy. It can work on 4Ghz easily. 65W TDP is also not much(2008?) it can handle +5GHZ sometimes(I think the best was 5.3 Ghz(which i9 9900K can't(joke)).


Poor

This CPU is very outdated for today's standards. It is found in most educational computers because it is very cheap. However, most people choose to put integrated graphics cards because they simply cannot afford a real graphics card. This cpu is very underperforming with only two cores, and even paired with a graphics card will struggle to run on the best titles. You'd be better off with a quad core cpu instead.
