Why xeon processors are so expensive?

[XSR]

And which Motherboard/Case/Memory will support them?
Is this CPU really contains 61 cores?
I talk about Intel® Xeon Phi™ Coprocessor 7120D PCI-e Card, Passively Cooled
Thanks

They are expensive because they are business processors, not typical end users. They have a ton of cache and cpu's, enterprise based solutions.

If you don't know why they cost so much, you don't need one, and you shouldn't want one.

Xeon Phi are add in cards that contain CPUs for doing enormous x86 multithreaded processes. They are not for running the computer. The system would still need a host processor.

Xeon chips support ECC memory, and usually a lot of memory. Form factor wise they are identical to the consumer grade CPUs and are somewhat interchangeable.

Xeon chips also support multi-processor boards, from 2 to 4 physical CPUs. Meaning that with the latest chips you can get something like 72 cores in a single machine (144 threads), neat.

Intel seems to have stopped much of this practice, but it used to be that consumer grade chips would have certain instruction sets and capabilities disabled. These days it doesn't look like they much bother.

Xeons are server CPUs, (very fast). They can have up to 10 cores and are usually used for business. They are not meant for recreational uses like gaming.

If you're talking about the xeon phi, it's a coprocessor card designed for specific parallel computing tasks. It doesn't add to or take the place of your actual system cpu. You can access it from within windows but the card itself runs on a micro os that's linux based so it doesn't run windows programs.
