Intel demonstrates a 28-core processor running at 5GHz

Is this a single 28-core CPU? The only other 28 core chips that Intel has are the Xeon platinum 8176 and 8180, which cost $9-$13K and don't clock nearly as high.

Or is this like AMD's Threadripper any EPYC, and they are duct taping together multiple CPUs in a single socket? Eg, 2 x 14 cores CPUS connected with QPI or EMIB ? 4 x 7 cores? I wonder if AMD patented this technique..

>duct taping together multiple CPUs

IIRC, according to Intel's slides, AMD used glue.

You know that intel has been stacking CPU before, right? Pentium D, etc. It's not like AMD is the inventer of thus technique.

It is very much likely as you guessed, an EMIB-driven CCX design. Comparable Intel CPUs retail for north of $10K but they're nowhere near 5GHz.
