Cheers, was just about to pull the trigger on an 8700K.
I think vs a delidded 8700k on anything that users 6 cores or less there won't be much in it. Anything using 8 cores there will be the obvious improvement. If you have a stock 8700k there should be a decent improvement with an 8 core soldered chip.
Coming from an 4790K so I might do the same. I want a taste of an i9 CPU!!! (at a decent price)
We have already seen the limits of Intels ring bus. Highly clocked quad core i7's expose the ring bus limit in a lot of situations.
Indeed, mesh plus more memory channels was the answer to Intel's problem. Trouble is it's a plaster on a gaping wound.
Adding more cores and pushing the speed of each just compounds the problem as the ring bus is swamped with more crosstalk between cores and because of how poor Intel are with memory scaling, increasing memory bandwidth can only help so much. The ring bus needs to go and hopefully will in 2022-3.

In terms of the amount of cores, yes. However he is talking about memory starvation. Googling shows nothing.
Super faceplam.
Your memory scaling is poor and starving your 8700K. We have discussed this many times...
Intel desktop chips can't scale well across cores. Again discussed many times...
The problem is the chips are designed and built around an ancient ring bus system. Ring bus sucks for what Intel are using it for. Thats why Intel dumped it on higher end parts and why you suffer the problems above.
Difference here is they swapped to Mesh for high core count CPUs, they've used Ring Bus for up to 12 cores per bus (they had a dual ring in their top Broadwell Xeons).
Anyone who thinks Ring Bus is going to be a bottleneck for <12 core CPUs should look back on 6950X performance.
Would help if @jigger provides even 1 shred of evidence to support his claim, but he never does.

All that comes from his mouth is never back up.
All comes from his deluded mind. My 6 core isn't starved for memory bandwidth and neither will these 8 cores.
I once read that the ringbus was designed with 8 core xeons in mind. I'll try to find it.
Meanwhile I'll be awaiting for some proof of th 8700k being memory bandwidth starved....

12 threads. Multi channel memory helps to some extent.

And yet not a single article to backup these wild claims.......
You are already fully aware of the problem Gavin, we've been through this many times before. You have confirmed as much 5 posts up....
Back under the bridge with you.

Perhaps you should find an article for me to read whilst under said bridge... 
In the meantime, as andrei has said. Take a look at the 6950x.

Perhaps.
