XFX Radeon RX480 Black Edition Review



The XFX RX480 Black Edition features a reference design cooler with flair. While this may be disappointing to some looking for custom cooler designs, it allows XFX to push the design to its limits. To give the card a more premium feel, XFX has equipped the card with a simplistic, yet functional backplate, with a cut out for the gpu core similar to that of the ones seen on their higher end Fiji chips.  


Display adapters include 3 display port 1.4 ports, and a single hdmi 2.0b port. Next we have 6pin power adapter sporting a massive 6+1 Power Phase, delivery a peak power output of 165 watts; which is at the very limit of the single 6pin adapter.


Under the hood the card sports a 1326mhz boost clock, which is a 42mhz over the Core Edition. The boost clock communicates over a 256bit bus with 8gb of gddr5 at the standard 8000Mhz effective clock.


This particular card absolutely loves being overclocked. The core clock hit a peak overclock of 1405MHz in synthetic tests. The memory overclocked surprisingly well too with an additional 200MHz. This translated into Frame rate increases across the board. For enthusiastic overclockers this board is a dream come true.


The reference cooler is the shortcoming for the card; The design is loud when at the one hundred percent mark that is required when overclocked. If you leave default fan profiles the card will thermal throttle and crash, and even at 100 percent the card hits high temperatures in the 90 degree Celsius range.


In conclusion,
If you are on a budget and enjoy tinkering with overclocking this card is right up your alley. However, while the fps numbers are astronomically high for the price point in some games AMD is yet to keep this consistent across all games. For pc gaming enthusiasts looking to just throw a gpu in and game without setting configurations, you may want to look into something that performs more predictably. I love the overclocking unicorn I got and am curious what numbers you guys are getting. Let me know in the comment section below.

AMD XFX Radeon Pro Duo: Benchmarks and Review

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.
