I think the answer to that has many variables... Intel have some pretty unique propositions for certain industries with their accelerator options but then that may only account for single digits in market percentages.
AMD hasn't kicked Intel in the nuts hard enough yet, Intel still has a very strong market share, only time will tell how and where they head now under new management.
But RAW IPC, AMD right now are the kings, though that isn't quite enough to suddenly make them the top-dogs... that industry runs very differently to the gaming sector.
I do feel there is a big comeback coming... and it may be sooner than we expect.... they've been in this position before, and they trumped the scene for over a decade before AMD could catch up...

yes, but this is not the full story.
you get motherboards e.g. with 8x PCIe x16 slots. you can install four modern GPUs, wasting 4 slots.
or 4 PCIe slots and some MCIO ? not for long cables, limited end devices.
It depends on the workload.
For some of the more complex FEA workloads, Intel trounces AMD because of the terrible inter-CCD latency AMD's architecture has. AMD architecture is also objectively worse in every way compared to Intel when it comes to memory bandwidth/performance too which compounds on the bad inter-CCD latency issue AMD has.
For VMs that don't do anything too complex, AMD is much better than Intel.

Intel is currently marginally better than AMD with 136 PCIe 5.0 lanes versus AMD's 128 on their respectively in single socket flagships. When going to dual socket Intel wins more convincingly since AMD uses PCIe lanes to connect CPUs together while Intel has dedicated PHYs for inter CPU connections.
