r11, a supermicro, returns the following
Marketing Name: AMD Instinct MI250X/MI250
whereas lockhart returns
Marketing Name: AMD Instinct MI250X

Interesting, thanks. I did not expect the r11 GPUs to have mi250X in their names.

to add to the confusion:
lockhart mi250X has 110 CUs
r11 mi250X/MI250 has 104 CUs
r9 mi210 has 104 CUs

yeah, I looked up the specs.
lockhart has proper mi250X. That's top-of-the-line 110 CUs in OAM form factor.
mi250 is the same number of CUs (104) as mi210 but in OAM form factor.
mi210 is PCIe.
