I thought this was already confirmed the lowest end x99 cpu chips would be only 28 pcie lanes. Others would be 40.

I hope that users remember this next year when they start complaining that they cannot run at least x8 on 3 GPUs if they go with the i7-5820K. Sad to that the i7-5960X can still only get 2 x16 cards same as the i7-4960X. I was hoping that we would start seeing 3 x16 GPUs.
"On motherboards with, say, three PCI-Express 3.0 x16 slots, the i7-5930K and i7-5960X will let you run two slots at full x16 bandwidth, and a third slot at x8. On systems with the i7-5820K, the second slot won't go beyond x8, and the third one will cap out at x4."

with 28 pcie lanes couldn't they got 3 x8 lanes? that's a total of 24 lanes, or is my logic flawed?

I guess for the most part we will have to wait and see.

We knew this already, didn't we? Was it just a rumor at the time? Sounded like it was confirmed when I first read about it. For the life of me, I can't remember where/when that was.

I'm not sure how a'rumor' is defined anymore since we've seen people straight make stuff up, speculate, treat info as truth, all the way to leaked info from slides that say "Intel" in them (and even those files could have been altered). Therefore it is more accurate to say 28-lane wasn't confirmed because it wasn't official. That being said, finding the info on a company website document can still fall into the 'leaked info' category since Intel hasn't officially launched X99 yet. Meaning it still isn't confirmed; but it is just safer to assume since we're within a week from debut. knightsilver
Thought thats what the Zseries was for? For Intel, progress is segmentation, they aren't trying to cut costs by lumping customers; they can afford to put people in a whole lot of places. Z-chipset was allowing the mainstream client platform to be overclocked, it retained the 16 lanes of PCIe and dual-channel DDR of previous generations-- because that is all most people need, hence called mainstream. It could be that the jump from 16 to 40 has shown Intel that not everyone buying the high-end platform uses all the features, so this would be their way of seeing who really needs what. Intel has enough of a premium attached to 8-core to not worry that they use a 12-core die with four cores disabled, the same logic may not work with other dies; so this 5820K and perhaps the 6820K successor as the entry-level Broadwell-E must be an experiment. That being said, I doubt this experiment is limited to X99; since LGA2011-3 socket is for their servers, no doubt there are Xeon E5 models w/28 lanes, and there may be many of them where one was unlocked and rebranded as "Core i7-5820K".

I understand that Lehpron. But, I just dont see the point of all that wasted effort, wasted R&D, cost and time.

Intel i7-5820K is best for people who use single cards or two cards. Better than 3-4 graphics on 4 cores. I thought i7-5930K will offer 8 cores but in this situation I would feel as I pay something I really don't need with i7-5930K. But i7-5820K is far better than i7-4790K. Memory not work any more at 1866MHz on Quad Channel, you see manufacturer offer 2133/2400/2666 and + kits for DDR4. Now I can build watercooling without hurry and without regret If I not build X99 first 6 months. In one moment I was scary what If I spend money on watercooling and then show up some excellent motherboards and Haswell E OC as crazy, but now with this offer I can build watercooling free.

It says with the 5820K, the first will run at x16, second at x8 and the third at x4. That doesn't seem right. Why not x8, x8, x8 when using three? You could even do x8, x8, x8, x4 couldn't you with four slots?
Either way PCI-e 3.0 x8 should still be fast enough for today's graphics cards.

But, I just dont see the point of all that wasted effort, wasted R&D, cost and time. Intel already designed the Haswell architecture (CPU and motherboards) years ago along with several dozen die configurations scaling from 1-core intended for low-power up to the possibly rumored 18-core server models for a half dozen sockets. All they do is to pick a configuration of cores and cache for a particular socket to 3D print a couple million onto silicon wafers and thereafter decide frequency or choosing models for branding. There are as many as 20 SKUs per brand-- it doesn't take whatever effort and R&D you're thinking of to develop an LGA2011 6-core with 14-lanes disabled (let alone picking one to unlocked, rebrand and disabling a few things to call it as "Core i7")-- the probability is very high several Xeon E5 models are planned with that same configuration, but maybe a different core count.
