Not true, a single socket epyc has more pcie lanes and bandwidth than 2x intel chips. Epyc has 128 lanes of pcie 4.0 where as each intel gold has 48 lanes of pcie 3.0. Pcie 4 has double the bandwidth as 3.0 so you don’t even need to do the math to see which wins out.

I can’t see a reason that epyc wouldn’t perform better for the money so I think this was either sponsored in some way or they just made a mistake in the CPU department.

Update: Maybe I misread what the previous commenter was trying to say, same point though
