June 4th, 2021 by rob-ART morgan, mad scientist


How fast does the AMD Radeon RX 6900 XT run versus other GPUs connected to or installed inside the iMac Pro?

GRAPH LEGEND

RX 6900 XT = AMD Radeon RX 6900 XT connected to the iMac Pro using the OWC Node Titan eGPU and the Dell UP2715K display
VII = AMD Radeon VII connected to the iMac Pro using the OWC Node Titan eGPU and the Dell UP2715K display
RX 5700 XT = AMD Radeon RX 5700 XT connected to the iMac Pro using the OWC Node Titan eGPU and the Dell UP2715K display
Pro Vega 64 = AMD Pro Vega 64 inside the iMac Pro

WHAT DID WE LEARN?

Even when installed in an eGPU box, the AMD RX 6900 XT renders much faster than other iMac Pro GPUs.

NOTE: the AMD Radeon RX 6000 Series requires Big Sur 11.4 or later when running on a Mac.
