Intel Core 2 Quad Q6400: Couldn't find it on Intel's website but Wikipedia mentions it (SL9UN). Haven't seen one in the wild, not even pictures.
Intel Core 2 Quad Q7100: Couldn't find it on Intel's website, Wikipedia doesn't mention it and I've only seen a single bad quality picture. The S-spec SLGUY doesn't even seem to exist.
Intel Core 2 Quad Q9250: Zero information, it's not mentioned by Intel&Wikipedia and no pictures available.

The Intel Core 2 Quad Q9700 & Q9705 (SLGZ2) are mentioned but haven't seen one ever. Why are these so rare? They are even more rare than the Extreme editions.

Found https://hwbot.org/hardware/processors?f ... entsfield) with 17 submissions for OC of a Q6400. The others are listed but N/A or no test results.

Interesting they call the Q7100, Q9700 & Q9705 as OEM only cpu's. Maybe Intel did a very limited release of those and never created the "ark.intel" category web page for them ? Just a guess.....
Did see them listed on CPU-World but like you said: no pictures....

Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun

Maybe. These CPUs are "only" 14 years old and still nobody knows anything about them. It must have been a really limited edition or they were recalled for some reason.

Some large OEMs are able to do special orders with Intel for CPUs that they would otherwise never make. Not surprised that these do not show up on the ark.

But how did they end up in the CPU-world database?
Where did those CPUs go? They recycled all of them? Why would an OEM buy only a limited number of CPUs if there are tons of production models available?

They may have been pulled from said OEM machines. From what I understand, these type of CPUs were/are generally ordered to fit into some specific performance and/or power level bracket.

They could even be still thrashing away in some weirdy specialist thin client boxes somewhere

Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.

Intel Core 2 Quad Q6400

What a pointless CPU

I don't agree .. At the time, quad cores in it self was kind of impressive, and with a reasonable cache size of 2x4 MiB it wasn't really a slug, in spite of "only" running 2133 MHz.

Please use the "quote" option if asking questions to what I write - it will really up the chances of me noticing 😀

I think that the post was referring to the Q6400 being pointless in the face of the Q6600.
But I could be wrong.

I do know that OEMs like DELL did get special supplies of non-retail Intel CPUs allocated to them and the same also happened with certain BTO OEMs who built workstation and high-end PCs that needed specific performance capabilities.
