Title: Dual-GPUs still alive: Apple-exclusive RDNA 2 Radeon Pro W6800X Duo beats AMD's RDNA 3 RX 7900 XTX and Nvidia's RTX 4080
Post by: Redaktion on February 28, 2023, 17:37:18
The Radeon Pro W6800X Duo is available as a US$5,000 upgrade for Apple's Mac pro 2019 workstations. It surprisingly supports Crossfire as well, so two of these cards can be paired together, which, in theory, could wipe the floor with the RTX 4090. Not a cost-effective solution by any means, however.

Yes, the MacPro is designed for two Duo cards (so 4 GPU chips).
AMD and Apple call the connector "Infinity Fabric Link".
See the diagram near the bottom of this page, scroll down.

Woah, I stand corrected. That's one beefy case.
