AMD’s Dual-GPU, Apple-Exclusive Graphics Beats RTX 4080 in One-to-One PC Pairing
It’s a pity that the Radeon Professional W6800X Duo has not made it exterior the Apple ecosystem. Contemplating the newest efficiency present, AMD’s twin Navi 21-based providing might rival the perfect graphics playing cards in the marketplace.
The Radeon Professional W6800X Duo has not one, however two Navi 21 (Sienna Cichlid) dies. They impart with one another via AMD’s Infinity Cloth interconnect. Sadly, AMD didn’t enable the Radeon Professional W6800X Duo to make use of the complete Navi 21 silicon. As a substitute, the chipmaker has disabled 20 CUs (computing items) from every Navi 21, leaving solely 60 CUs or 3,840 SPs (stream processors) within the Radeon Professional W6800X Duo. Every Navi 21 die additionally comes with 32GB of 16Gbps GDDR6 reminiscence and 128MB of Infinity Cache in a 256-bit reminiscence interface.
AMD constructed the Radeon Professional W6800X Duo particularly for the Mac Professional; subsequently the graphics card makes use of Apple’s proprietary MPX (Mac Professional eXpansion) type issue. The enlargement module has no exterior energy connectors, so Apple combines an ordinary PCIe x16 connector and a customized connector for added energy supply. The Radeon Professional W6800X Duo has 400W, so a single PCIe x16 enlargement slot is not sufficient to produce sufficient juice to the graphics card.
Elite excessive overclocking Roman “der8auer” Hartung (opens in new tab) Made the Radeon Professional W6800X Duo run on an ordinary motherboard with some intelligent modifications. First, he linked the graphics card to the PCIe enlargement slot utilizing a daily PCIe x16 riser cable, after which soldered two 12V and two floor wires from the 12VHPWR cable to the Apple connector.

Solely the GeForce RTX 4090 can beat the Radeon Professional W6800X Duo. The Ada Lovelace flagship beat the Radeon Professional W6800X Duo by a major 27%.
The Radeon Professional W6800X Duo is a graphics card for professional customers, but it surely’s all the time nice to see how the {hardware} performs in video games. Apple is promoting the Radeon Professional W6800X Duo MPX Module for $5,000, so it isn’t a toy anybody can get to play with. Congratulations to Hartung for buying one to indicate us the way it compares to trendy graphics playing cards, even when it is simply an general gaming benchmark, regardless of paying rather less for the Radeon Professional W6800X Duo.
