Those who got the 8700k

Pretty sure the 8400 runs fine on the stock HSF, it's lower clocks and lack of HT means it doesn't heat up nearly as much as a 8700 would on workloads that peg all cores @ 100%.

Even if you were to upgrade the stock HSF, it has been proven that a $20 EVO 212 is more than sufficient to cool a stock 8700, let alone a 8400, to ensure max turbos are hit. That is hardly 'expensive' cooling. It's only the K models that require a high end HSF or AIO cooler because 5GHz with increased volts does increase temps significantly.

Suppose your parallelism isn't perfect, and suppose the chips drop to their base clocks, then the cheaper 8350K outperforms the more expensive 8400 in virtually all cases. Only if you can actually use 6 cores and the parallelism is more than 97.3% will the more expensive 8400 barely squeak out a win in that base clock situation. To me, that isn't a value chip when it rarely wins. and when it does win the wins are small (especially when it loses, it loses by a lot the base clocked 8400 is 1/3rd slower than the base clocked 8350K at 50% parallelism). That and the 8350K could be overclocked if you wish to make the value of the 8400 even worse.

Of course, if you can keep the 8400 in turbo all the time and keep the 6 cores fed, then it is faster.

But, the problem is that the really good value chips (such as the 6600 and 7600) are not yet available in Coffee Lake. The 8400 is only good if you can keep it in turbo which requires expensive cooling (destroying the value of a low-end i5). .

What do you call expensive cooling? The 8400 with a $20 cooler will run prime or the intel burntest all day long without any throttling. I can say the same thing for the 8600k.
You clearly have no idea what you are talking about.

Any cooling that can be good in a dust covered 4-year old CPU inside a enclosed computer desk.

Clearly you haven't done the speed calculations. Even if the cooling is $0, the 8400 rarely wins to a cheaper chip.

Sorry but, any OEM selling the 8400 today will have to cool sufficiently to keep the PC humming along for years. If there are enthusiasts buying this CPU with no intention of cleaning their case out for years on end.. wait why are we discussing this? Waste of time.

It might be interesting if they added edram like Broadwell C, which could help cpu performance as well.

At this stage, Intel has kicked eDRAM off their desktop lineup completely. It may not even help now that people are pushing such high DDR4 speeds. We'll never know.
