![]() ![]() Heck, AMD even touted the card’s overclockability (that’s a word, right?) at its E3 unveiling. With power pins capable of sucking down 100W of additional energy, a liquid-cooling solution rated for up to 500W of thermal capacity, and a redesigned AMD PowerTune/OverDrive that gives you more control over fine-tuning your card’s capabilities, the Radeon R9 Fury X seems tailor-made for hefty overclocking. Subjectively-as I don’t have a decibel meter on hand-the Fury X’s radiator fan creates more sound than the fan on Nvidia’s reference GTX 980 Ti and AMD’s own R9 295×2, though I still wouldn’t call it loud. Despite AMD’s claim that the fan stays more than 10 decibels quieter than the Titan X’s air-cooled blower, however, I was surprised by just how much noise it puts out. AMD says the cooler itself is rated for up to 500W of thermal capacity.ĭeploying water-cooling indeed keeps the Fury X running nice and cool. It’s a slick custom design built in conjunction with Cooler Master, rocking a 120mm fan from Nidec on the radiator. Rather than going with a typical air-cooling solution, with a fan or blower, the Fury X utilizes an integrated closed-loop liquid cooler that’s basically a more refined version of the beastly Radeon R9 295×2’s water-cooling setup. That extends to the Fury X’s cooling system. There’s also a small green LED next to those that illuminates when AMD’s ZeroCore technology puts the Fury X to sleep. It’s super-dumb but honestly, it thrilled me to no end watching those little LEDs flare to life when booting up a game. The harder you push the card, the more LEDs light up. You’ll find an illuminated red Radeon logo on the outer edge and face of the card, along with a new “GPU Tach” (as in “tachometer”) feature that places 8 small red LEDs above the power connections. See the “GPU Tach” LEDs just above the two 8-pin power connectors? ![]() The decision not to go with HDMI 2.0 limits 4K video output to 30Hz through the HDMI port, so gamers will want to stick to using the DisplayPorts. There’s not even an exhaust grille on the I/O plate, which rocks a trio of full-sized DisplayPorts and an HDMI port that’s sadly limited to the HDMI 1.4a specification. Everything’s covered, even the sides and back of the card. The 7.5-inch card is built from multiple pieces of die-cast aluminum, then finished with a black nickel gloss on the exoskeleton and soft-touch black everywhere else. Again, our previous coverage has much more info if you’re interested.ĪMD spared no expense on the physical design of the Fury X, either. It’s clocked at 1,050MHz, promises 8.6 teraflops of compute performance, and draws 275 watts of power through two 8-pin power connectors that can draw up to 375W. Moving past memory, AMD’s new “Fiji” GPU is nothing short of a beast, packed to the gills with a whopping 4,096 stream processors-compared to the R9 290X’s 2,816-and 8.9 billion transistors. The AMD Radeon R9 Fury X’s technical specifications. Gaming at 4K resolution can eat up memory fast once you’ve enabled any sort of anti-aliasing. While AMD CTO Joe Macri told us in May that’s all developers really need for now, it definitely proved to be a problem in our testing when playing games that gobbled up more than 4GB of RAM- Grand Theft Auto V, specifically. Technological limitations capped this first-gen HBM at just 4GB of capacity. All that memory bandwidth makes for great 4K gaming, though it doesn’t give the Fury X a clear edge over the 980 Ti when it comes to games, as we’ll see later. The Fury X’s memory is clocked at a mere 1Gbps, but travels over a ridonkulously wide 4,096-bit bus to deliver effective memory bandwidth of 512GBps, compared to the GTX 980 Ti’s 336.5GBps. ![]() While GDDR5 memory rocks high clock speeds (up to 7Gbps) and uses a smaller interface to connect the GPU-384-bit, or 512-bit in high-end graphics cards-HBM takes the opposite approach. The stacking lets 1GB of HBM consume a whopping 94-percent less on-board surface area than 1GB of standard GDDR5 memory, which enabled AMD to make the Fury X a full 30-percent shorter than the Radeon R9 290X. HBM stacks DRAM dies one atop the other, then connects everything with the GPU using “through-silicon vias” and “µbumps” (microbumps). ![]()
