Intel Confidential CPU means, pre-production processors; Intel provides these processors to computer manufacturers for testing purposes, they are Intel property and not for sale.
I suggest you to contact the place of purchase and request a refund on them.

What is an Intel engineering sample processor and is it eligible for a warranty?
Hello there Mike.
Very interesting; I just a couple of days ago received my i7-6900K processor and I'm pretty sure it said that too, Intel Confidential.
But at that moment I didn't take any notice of it, not until now after reading the previous message.
I therefore took the original box the processor arrived in and checked all numbers, but the box says:
S-spec: SR2PB so that seems to be OK. And the box sealing was not broken at arrival.
I then checked my one year old i7-5930K, which is now back in it's original box and it doesn't say anything as Intel Confidential.
Is it possible to find out, by any of the numbers on the box or by any of the Intel CPU software tools, if I'm right or wrong...really don't want to take apart my whole system again to get access to the top of the CPU. You see, it's running on the Intel TS13X liquid cooler and no matter how much I stress it, it never get really hot. I therefore know my Artic Silver 5 has been put spot on. Furthermore the original Intel radiator fan has been replaced by 2 Noctua 120mm industrial fans, going as high as 3000rpm (push/pull).
The 6900K CPU itself is working perfectly, no problems what so ever. It's mounted in an ASUS X99-Deluxe II motherboard and by using the BIOS defaults it just jumps up to 4.2GHz when needed.
But I don't like if it was an Intel Confidential there was in the box. That's not what I ordered and paid for.
Furthermore, I would really like to know the t-case max for this CPU, it's not mentioned anywhere. All I can find is: Will be added later...???

The Tcase temperature of the processor is 71 Celsius degrees. More details in the link below:
In regards to the processor markings, the box and processor have the same Batch and Serial Numbers.
It is possible to determine if your processor is a sample (pre-production) or not using our Intel® System Support Utility
Thanks for your answer. I downloaded and ran the Intel-SSU on my i7-6900K system and below is a link to the outcome from the CPU info, to be downloaded and viewed with ISSU:
I had a look at it, but it didn't make me much wiser.
Regarding the t-case max; Before I put the question about the t-case max temperature I had already scanned both the volume 1 and 2 data sheet files, but could not find anything. It just pointed to the 3th sheet that was missing...saying it will come later.
So Mike, where did you find the 71 degrees C?
I had no problem finding it for my i7-5930K.
But in the meanwhile I've done some research myself and found out that we, the customers, are talking too much about the t-case or package temperature as I think you call it in XTU. Actually the t-case max, calculated from other values, is for those who design and make heat-sinks and therefore without interest for us.
What we should really care about is actually the core temp. or tj-max as some people also calls it. On my CPU it is said to by 100 degrees C and I have never ever been near that value. As I wrote in an other thread, I reached a peak of 80 degrees C while running 4.5MHz full load, using the stress option in Intel XTU. Also the CPU is protecting itself from running to hot by shutting down the system if it happens.
But what can then really kill the CPU? - Some might ask.. yes, the input voltage can - if it's set to high - so be careful.
And of cause I have to mention this; if the CPU or anything related to it, like the motherboard, RAM etc etc. is not handled with proper ESD "ElectroStatic Discharge" protection you will harm the devices.
So Mike, I'm looking forward to hear from you when you have had a look at my CPU XML file.
Thank you for your feedback. I reviewed the results of SSU and your processor seems to be an Intel Confidential. The FPO and ATPO (Serial Number) were not recognized.
It will be necessary to take out the processor from your motherboard just to confirm the processor markings.
Well, I just had to know. So today I took apart my system to get access to the top of the CPU. I have attached a couple of pictures:
And one more of the box:
As you see, S/N and Batch# are matching. So my processor is NOT a pre-production release.
So I very sorry for the inconvenience I may have bought to you. I've no idea where I got that Intel Confidential from, incredible how wrong a brain sometimes can be.
Now for some strange stuff; I removed the old Arctic Silver 5 from the CPU. Had to release both lock levers and so on, but didn't remove the CPU which is mounted using a special CPU mounting kit from ASUS, so it doesn't move when touched. Applied new Arctic Silver and assembled everything again.
Now at power ON; PC powered ON, then shut down and stayed that way for some seconds before it powered up again - just to shut down once more...I said to myself, **** - something is wrong.
But it started up again and quickly showed some information in the upper left hand of the screen about the CPU I think. But it was gone before I could read it all. Now it showed the POST screen, saying; CPU has been changed, press F1 to enter BIOS.
So I did and applied the default setting, saved and rebooted.
It did the same again, powering ON/OFF a couple of time before it loaded Win 10.
Everything seemed to work. I ran CPUID CPU-Z and believe or not, for the first time since I got my new RAM, it had set my RAM frequency to the desired 3200MHz and not 2133MHz as before.
BUT Intel-SSU still doesn't show right information, so this seems to be an issue with Intel-SSU, please let programmers know about this.
I'll now run some tests on my system and I'll be back, as he said.
I am glad your system is working properly. I suggest you, verify if motherboard has already the latest BIOS. In regards to memories, the processor supports memories of DDR4 2400/2133MHz. It can handle memories with higher speed but system might show random glitches or low performance.
