Default Intel CPU prices going up?

Looks like one silicon die to me. There are two IP blocks on it.

On the mobile part, there is one IP block (4 cores/8 threads)

HTH,

The Ryzens use 4-core CCX's, while the Threadrippers use 8-core CCX's.
Here's the Ryzen block diagram:

And that's exactly what my quotes above, provide.

The Ryzen product (APU flavor), uses a new die,
with a 4 core CCX and a GPU. The "IP" (Intellectual Property)
block size is a 4 core CCX, which is getting reused.

In the Zeppelin core, two 4 core CCX IP blocks
are combined on one 8 core die. The 8 core die
is replicated as four dice in an Epyc. This means
they're manufacturing 8 core parts on the silicon
wafer.

There is a grand total of two die designs.

Ryzen as APU 4 core CCX + GPU on a single die --- A unique
design
Ryzen desktop two 4 core CCX Zepplin in a single die \
\
Threadripper two dice of the "Ryzen desktop" persuasion \ The idea
two dummy dice (replaced by working dice \ is to
in the next generation, dice don't have RAM / reuse
connected). / the same
Epyc four dice of the "Ryzen desktop" persuasion / silicon die

So they are required to yield 8 core component parts. To make
some of the more profitable packaged products.

This diagram is an eight core silicon die. The red line, is an
architectural shortcoming, not a "snip point".

The die is one continuous thing.
