The XFX Radeon Pro Duo is an interesting product in the gaming gpu market. While AMD targets developers with the line, XFX still appears to be targeting gamers with their branding.
Display adapters include 3 display port 1.2, and a single hdmi 1.4a port. In my experience the HDMI port detects displays poorly and causes artifacting without configuration. I have seen this issue on the rx 480 as well.
Next we have a whopping total of three 8pin power adapters sporting fifteen full length power phases delivering up to 575 watts.
Under the hood the card sports a 1000mhz boost clock, which we were able to overclock to 1100MHz. The core communicates over a huge 4096bit bus at 1024GB/s with 8gb of HBM at a 500Mhz effective clock and 1GB/s data rate. I highly recommend looking up High-Bandwidth memory to fully understand why the data rate is important to specify.
The reference designed cooler performs well, which is a requirement when your Thermal Design Power is 350 watts and honestly higher considering AMDs calculations differ from Intel and NVIDIA. Nevertheless, the All-in-one design dissipates all the heat keeping the two Fiji chips cooler than mcdonald’s keeps there frozen yogurt, so about 50 degrees Celsius.
If you are a serious fan of AMD, or you are a developer that wants a big ass bus to play with, the XFX Radeon Pro Duo might be up your alley. However, if you are a pc gaming enthusiast looking for the most bang for your buck, move on padawan. The disappointedly low fps numbers and lack of Crossfire support in key games like doom makes the $1200 feel even more steep than when you clicked buy.
