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]

I loved this thing, so much nostalgia, any sort of cpu intensive game ran like crap and any modern game will. But god, after an overclock, it really tells you how far ryzen has come on their single core, aka no where. This thing is a cheap beast, going for like $45. Don’t ever really buy it though, just get like a FX-6300, 6 cores, 6 threads versus 1 core, 2 threads at $90 (+$45 more). If you’re truly set on a $50 CPU, buy a A8 6600K. Saw those floating for the same price as this but with quad core. Overall making this product obsolete, but still no where near the worst of old tech. Especially a 6 year old product that still arguably has a fight and a half left in it. I mean it is extremely unlikely you’ll find a use for it, but under the right circumstances, I.E a strictly single core game, after a pushy overclock and in theory you would get the same FPS as a modern ryzen, as in 2020 product. P.S. Over clock the absolute hell out of this thing for the real performance. [Jan '21 ThatGuyRandomly]
