Let's drop the pretenses, for most games, a hyper-fast quad core is still going to smoke these high core count chips from both Intel and AMD and it'll require much less exotic cooling, too.

Actually, no. The 18c chip should be the fastest gaming chip around, assuming you can figure out which cores to leave enabled to assure proper dissipation of heat. All that extra L3, with only 4-6 cores enabled, will make for the fastest Intel gaming chip. That's a lot of money to pay out just to disable most of the cores, though!

Let's say you are a wise gamer and realize the correct way to build a rig that will last a while is to get 8 cores. I think most here agree on that.

I'm thinking 6 is a better target, especially for someone who is budget-conscious.

I'm sure that free enterprise will provide de-lidded and binned chips for us.
Yes, and after a few generations Intel will just give us the die and PCB with the pin array and resistor/capacitor banks and we'll have to assemble our own CPUs with different flavors of IHS.

Can you manually disable cores on the 18 core part? I didn't know that.

I'm yet to see this claim put to test - that few cores and a large pool of L3(by large I mean more than 8MB), would give a significant boost to gaming performance than the same number of cores but with smaller L3. There are Xeons that fit the bill which one can test with.

If you can't disable cores on Skylake-X systems, I'd be shocked. But then they didn't use solder either, and I'm still shocked by that.

Xeons generally can't be overclocked. I would imagine that the 18c Skylake-X will be able to hit 4.6.-4.8 GHz with a lot of cores disabled. As for L3's impact on gaming, there are more than a few gaming benchmarks where chips liket he 5960X and 6950X came out on top vs. the 6700k (stock settings) just from the L3. And don't forget all the benchmarks won by the 5775c on account of l4.

One needs to test it like this - take a 5960X, match core count to a 4770K at 3.5GHz and use dual channel memory. Only then can we be certain about the impact of L3 size. As for L4 on the 5775C, it is basically akin to having 3200MHz CL14 memory when explaining its performance.

We already have delidding services available. It's only a matter of time, imo. If it's just the same adhesive and TIM, it shouldn't be a problem, or that much of a risk. People have delidded the 6950X.

There is no reason to accept this trend as normal and the way forward from now on. There are lots of people who want a reasonable OC but refuse to delid.

Plus, delid options aren't available everywhere.

If you have to delid your CPU to get the best out of it, then it was packaged wrong. You really shouldn't roll over and accept that.

I have no problem at all with Intel's policies. They are a for profit business, not a romantic notion, just like AMD. Neither Intel nor AMD gives a flying screw about me, and I hold no illusions about either.
The idea of getting upset because a company doesn't do what you think they should, or liking a company because you think they do, baffles me.

All I basically care about is that the product does what is claimed at a price I can stand.

I don't care what's under the IHS. If the product does what is claimed, that's all I need. If the product fails to meet specs, then I have a problem with it.

What are Intel's reasons for using a worse thermal solution that is outperformed by previous solutions by 10 degrees?

If there is any, then I have no problems accepting their stand on this. Specifications don't matter because they can just increase their advertised Tjmax and claim that everything is fine.

If they don't come up with an explanation they will lose customers. It's that simple.

This. Personally I'm skeptic about using TIM in these CPUs, but we should hold judgement until reviews and most importantly until people get their hands on the product.

I will say this though: defending Intel's decision with arguments based on how easy and/or beneficial is to delid need to stop. Either the TIM does the job, or it doesn't.

Reliability. They want the CPU to last until you actually need that performance (especially for their high cost Skylake-X processors). Intel doesn't care about the very few Skylake-X customers who want more overclock performance for less reliability. Yes, they will lose those customers. Not that you would be a customer anyways.

I'm currently on a Core 2 Duo E6300 that is in its 11th year, in tropical climate.

Then you are not a Skylake-X customer who needs maximum overclock.
When did I say that that's the only thing I work on?

First it was no solder because small die, now it's reliability. Plain BS I say because they can get away with it because nobody does long term tests just like testing for degradation with high Vcore.

His point is that to reach Turbo 2.0 speeds on all cores you have to delid your 600-1000$ chips.

If that turns out to be an issue, then Intel will have a problem. PPL won't spend that kind of money on an HEDT platform that won't meet Intel's own specs.

You know what I just about can't believe? That Intel is still charging $400 for their 6 core chips. That's nearly double the price of the R5 1600, and that Ryzen chip is seriously very good and capable. Its just about $200 bucks. For the price of a single skylake 6 core (CPU only) you can just about get a CPU, motherboard AND ram, and given the fantastic TIM debacle, your performance will only be about 15-20% behind. You must also add in the cost (and risk) to de-lid. Maybe Intel will do better with coffee lake 6 core. I feel like Intel just really blew it with this release.
When I saw the price of the 8 core skylake, I figured it was priced a little high, but reasonable if comparing to the 1800X. Of course no one buys the 1800X anyway with the 1700/1700X around. But anyway, I was genuinely excited about the skylake 8 core chip. I saw all the fancy new boards and the price of the 8 core skylake and told myself, "Yes, this is what I always wanted all along but just didn't have the patience to wait for". I had my chance to perhaps sell off my platform and impulse buy the Skylake and ride that 4.6ghz goodness off into the sunset, living happily ever after. Then I saw the word "TIM" written somewhere and my heart literally ripped in half.
I knew exactly what that meant. It meant temps in the 80's, regardless of cooling. I knew my custom loop wouldn't do jack to offset the crappy conductivity of a massive TIM gap between the die and HS. My 6800K suddenly feels like a premium product with its nice soldered connection and mid to upper 50's temps.
What a shame. Just filthy.

EDIT: Maybe they are saving the soldering for their 14nm++ refresh series chips. They know they need to entice enthusiasts to buy more chips in 12-18 months, and that would certainly be one way to do it. Give us TIM now, and the only way to scratch that annoying itch is to buy a nice soldered refresh chip later. Higher clocks, proper cooling etc. It will seem like a good deal!
