A
report last month said that Intel would be looking to adopt TSMC's 3nm process for its upcoming Meteor Lake processors. Intel currently doesn't utilize any smaller processes, and handing off the job to a third-party, such as TSMC, is a way Intel can possibly catch up to Apple.
There are a couple of rumors/leaks that Meteor Lake "processors" are
not a single monolithic die solution. More like the Meteor Lake multiple "tile" ( chiplet) package that servers as a "Processor".
Going to TSMC isn't necessarily for x86 cores.
Intel's Xe-HPC Ponte Vecchio chip is composed of :
" While the compute tile is based on TSMC N5, the Ponte Vecchio Base Tile is on Intel 7....
...We discussed Xe link but this is based on TSMC N7. Typically we see SerDes and switch tiles on older nodes as they can be harder to scale...."
The Intel Ponte Vecchio is a spaceship of a GPU that required Intel's chipbuilders to innovate across many vectors

The Xe-HPG , Arc Alchemist GPUs are based on TSMC 6. [ basically done at this point. Drivers are holding back the large scale launch at this point. CES 2022 should present some movement there. ] . It is a larger monothilic chip. However, Intel's GPU line up is seriously looped into TSMC advance processes. It has
already happened; there is little to no "rumor" there.
If Intel is looking to do a GPU 'tile' for the Meteor Like package , the huge burning question would be why would it
NOT be on TSMC????????? The new Xe-core that Intel has developed already has
two implementations on TSMC. One in TSMC N6 and
another in TSMC N5 . After N6 and N5 going to N3 is a relatively standard ( almost mundane) progression. A second (or third) generation 'new' Xe Core probably would not get much from going to N4. And timeline wise 2023 is a better window to iterate on GPUs for Intel..... so ... N3 . What else would they pick?
A week old 'Rumor"

If Intel is trying to play "catch up" in iGPU 'horsepower' , then the GPU tile is the one that has the greater need to move forward to pack more "compute" and cache onto the die. Not the CPU cores. In 2023 Intel should have their Intel 4 ( old '7nm') process up and running.
There is a Xe-HPG graphics core generational change coming in 2024-2025 . Maybe that will switch back to Intel fab if they have worked out a way to get back on steady updates, but before then GPU tile is likely sticking to TSMC.
This negotiation is probably more so about timing during the calendar year and Intel not wanting to get into a bidding war over fab capacity. Intel doesn't want to over spend here, but also probably not looking to just eat table scraps that Apple dribbles over the edge either. There is some balance of pre-pay and guarantees that Intel needs to set up to secure the number of starts they need.
By doing the compute (and possibly I/O ) tiles with Intel 4 (and Intel 7 or TSMC N5 ) Intel will need far fewer N3 wafers than Apple would with dies that had both CPU and GPU (and cache for both) on them. Chucking the CPU cores gets more GPU tiles built with a limited number of wafers. The "problem" Intel is likely juggling here is that they don't want to have large mismatch in the supply of CPU and GPU tiles for assembly. They are going to need enough wafers to pair up with the wafers that are going through the Intel fabs. [ If the base/SOC tile is N5 then might be leveraging TSMC packaging. If majority are intel then Foveros/EMIB ]
Somewhat skeptical that Intel is going to ship the bleeding edge 86_64 implementation off the TSMC if they don't have to. Additionally Meteor Lake has been in flight for over a year at this point. It has probably been tagged for Intel 4 since the baseline design started. It would be odd to switch late in the game for such a performance tuned piece.
If they were super hard pressed to do a monolithic die variant then those would be better odds. With tiles they can ship out a subset of the work.
