Pros: Better than the reference RX 480. Dual bios configuration. Three fan design provides low noise and good cooling. Decent overclocking. More energy efficient than the previous generation of AMD Cards. Good gaming performance.
Cons: Longer than the other cards (12.2 inches), which may be an issue for some cases. No option for LED's. (Minor) Red Devil Emblem on the card is upside down. (Minor)
Overall Review: I was looking for an upgrade from my old R9 280X, and decided to get the RX 480. I read a lot of decent reviews online about the PowerColor Red Devil card, so I decided to go with it. When I went on Newegg, I saw that there were two versions of the card. From what I was able to determine, the only differences between the two cards was that Version 1 of the card had a boost clock of 1330MHZ from the factory, and the Seal of Solomon on the back plate. Version 2 had a boost clock of 1290MHZ from the factory, and nothing on the back plate. Since there were no significant differences between the cards and since Version 2 of the card was cheaper, I decided to go with it. After installing the card in my computer, I acquired the unlocked bios from the Power Color Devil Club forum and flashed the card with it, which changed the boost clock from 1290MHZ to 1330MHZ, and changed the max power limit from 30% to 50%. One of the first things I noticed was that the stock voltages on the card were a little too high, so I decided to undervolt it. Apparently the RX 480 undervolts real well, because I was able to save 20-30 watts of additional power and drop my card temperatures. Before undervolting the card my idle temp was about 50 Celsius, and load temps were 75-80 Celsius. After undervolting the card my idle temp was about 40 Celsius, and load temps were 65-70 Celsius, which was a difference of 10 degrees Celsius lower. My fan profile in Wattman was 1500-3000 rpm before and after undervolting. After undervolting the card, I decided to try overclocking. My results are listed below: Card: PowerColor Red-Devil RX 480 (Using unlocked bios) ASIC quality: 79.4 Case: Cooler Master HAF 912 Overclocking tool used: AMD Wattman My fan profile on Highest Stable Overclock: 2800-3800 rpm Highest Stable Overclock: 1395MHZ (Boost Clock) at 1175mv, and 2125MHZ (Memory) at 1150mv. Miscellaneous notes: Anything above 2125MHZ (Memory) would generate GPU memory errors. A few GPU memory errors are fine, but when you start seeing several hundred to several thousand then you will start to get diminishing returns on your memory overclock. Anything over 2200MHZ would result in thousands of GPU memory errors making the system too unstable causing system crashes that would require a reboot. VRM temps never exceeded 80 Celsius. I cycled through the Fire Strike, Time Spy, and Heaven benchmarks twice, and then played Fallout 4 for an hour to get these results. One tool I used to monitor the card while overclocking it was a program called HWiNFO64, which is a free download and comes with a lot of sensors built into it including GPU memory errors, core voltage, card wattage, core clocks, GPU temp, and VRM temps just to name a few. Update: Using Sapphire Trixx, I was able to get the card’s Boost Clock stable up to 1430MHZ at 1200mv. Trixx adds extra voltage to your existing wattman values for state 7. My default voltage from the bios was 1150mv for state 7, so I needed to add 50mv using the Trixx program to get 1200mv total. Higher boost clocks of 1450MHZ may be possible with a little more voltage to say 1250mv, so if I decide to push for a higher overclock I will update this review. Remember that when it comes to overclocking, individual result will vary and that AMD recommends a minimum power supply of 500 watts for the RX 480.
