EPIC's CEO is an idiot.

The Metaverse will not exist without Apple's participation.
Apple will create the Metaverse that people want to use.
Only Apple can create the glasses that people will want to use to access the Metaverse.

Even Facebook has given up on the Metaverse.
They realize that they cannot do it alone without Apple's help.

Apple's Mac Pro could run GPUs on PCIe slots.
But someone - and it won't be Apple - has to write drivers to allow the GPUs to work with MacOS.
Who is going to do this work???  AMD?  nVidia?

Since the GPU is not on the Apple Silicon System-on-a-chip die, it will be generally slower than Apple's on-chip GPU.
But, at least you can run a GPU.  And if the GPU is a beast powerful enough, perhaps it can make up the speed difference compared to the Apple on-chip GPU.

In regard to RAM.  Apple could add a memory controller to run external RAM like a huge cache.
Obviously the bandwidth is going to be slower than using Apple's on-chip RAM.  It can never be used as working RAM
since it will be too slow.
But at least it is expandable --- perhaps to 2 TB of external RAM.
The Apple Silicon On-Chip RAM is the working RAM. It will fetch data from the external RAM/cache when necessary.
Apps can be preloaded, or offloaded when not being used to the external RAM.
Of course, one problem with 2TB of RAM is that you have to store 2TB of data from the RAM every time you turn the Mac to sleep or turn it off
so that the Mac Pro can wake up instantly. 

AppleInsider said:

After missing a commitment to trounce Apple in 2022, it will also miss its 2023 promise, as Qualcomm is now promising its Apple Silicon-beating processors will ship in 2024.

Read on AppleInsider

For Qualcomm chips to beat Apple Silicon, Qualcomm chips have to be FASTER THAN INTEL 13th generation x64 CPUs.
I seriously doubt they can do this.
