ASUS went all out with the design of the ROG STRIX RX 480 O8G GAMING card, almost nothing on this card remains a stock part from cooling to power regulation.  It ships with a GPU clocked at 1310MHz in GAMING mode and 1330MHz in OC mode, [H]ard|OCP reached a stable 1410MHz GPU and 8.8GHz VRAM when manually overclocking.  The card does come at a premium, roughly $50 more than a stock card which makes it more expensive than NVIDIA's GTX 1060.  The bump in frequency helps narrow the performance gap between the two cards, but it doesn't make this RX 480 a clear winner.  Check out the full review to see how it performs in the games which matter to you.

Asus ROG STRIX RX 480 Graphics Card Coming Next Month

Following its previous announcement, Asus has released more information on the Republic of Gamers STRIX RX 480 graphics card. Pricing is still a mystery but the factory overclocked card will be available in the middle of next month!

In my previous coverage, I detailed that the STRIX RX 480 would be using a custom PCB along with Asus' DirectCU III cooler and Aura RGB back lighting. Yesterday, Asus revealed that the card also has a custom VRM solution that, in an interesting twist, draws all of the graphics card's power from the two PCI-E power connectors and nothing from the PCI-E slot. This would explain the inclusion of both a 6-pin and 8-pin power connector on the card! I do think that it is a bit of an over-reaction to not draw anything from the slot, but it is an interesting take on powering a graphics card and I'm interested to see how it all works out once the reviews hit and overclockers get a hold of it!

The custom graphics card is assembled using Asus' custom "Auto Extreme" automated assembly process and uses "Super Alloy Power II" components (which is to say that Asus claims to be using high quality hardware and build quality). The DirectCU III cooler is similar to the one used on the STRIX GTX 1080 and features direct contact heatpipes, an aluminum fin stack, and three Wing Blade fans that can spin down to zero RPMs when the card is being used on the desktop or during "casual gaming." The fan shroud and backplate are both made of metal which is a nice touch. Asus claims that the cooler is 30% cooler and three times quieter than the RX 480 reference cooler.

Last but certainly not least, Asus revealed boost clock speeds! The STRIX RX 480 will clock up to 1,330 MHz in OC Mode and up to 1,310 MHz in Gaming Mode. Further Asus has not touched the GDDR5 memory frequency which stays at the reference 8 GHz. Asus did not reveal base (average) GPU clocks. I was somewhat surprised by the factory overclock as I did not expect much out of the box, but 1,330 MHz is fairly respectable. This card should have a lot more headroom beyond that though, and fortunately Asus provides software that will automatically overclock the card even further with one click (GPU Tweak II also lets advanced users manually overclock the card). Users should be able to hit at least 1,450 MHz assuming they do decently in the silicon lottery.

For reference, stock RX 480s are clocked at 1,120 MHz base and up to 1,266 MHz boost. Asus claims their factory overclock results in a 15% higher score in 3DMark Fire Strike and 19% more performance in DOOM and Hitman.

Other features of the STRIX RX 480 include FanConnect which is two 4-pin fan headers that allows users to hook up two case fans and allow them to be controlled by the GPU. Aura RGB LEDs on the shroud and backplate allow users to match their build aesthetics. Asus also includes XSplit GameCaster for game streaming with the card.

No word on pricing yet, but you will be able to get your hands on the card in the middle of next month (specifically "worldwide from mid-August")! 

This card is definitely one of the most interesting RX 480 designs so far and I am anxiously awaiting the full reviews!

How far do you think the triple fan cooler can push AMD's Polaris 10 XT GPU?

Meet ASUS' DirectCU III on the Radeon Fury

Tagged: Fury, DirectCU III, asus, amd

The popular ASUS STRIX series has recently been updated with the DirectCU III custom cooler, on both the GTX 980 and the new Radeon Fury.  This version uses dual-10mm heatpipes and Triple Wing-Blade fans which are billed as providing 220% larger surface area as well as an increase in air pressure of 105%, which provide a claimed 40% reduction in temperature.  We cannot directly compare the cooling ability directly to the retail model, however [H]ard|OCP's tests show you can indeed cool a Fury on air, 71C at full load is lower than the 81C seen on a GTX 980.  Even more impressive is that fans were only at 43% speed and operating almost silently, at the cost of increased noise you could lower those temperatures if you desired.  Check out their full review to see how the card did but do take note, [H] does not at this time have access to the new GPU Tweak II utility required to overclock the card.

-update - now with less X's

"AMD's Radeon Fury X is here, the AMD Radeon R9 Fury presents itself and we evaluate a full retail custom ASUS STRIX R9 Fury using ASUS' new DirectCU III technology. We will compare this to a GeForce GTX 980 using the new drivers AMD just released and find out what kind of gameplay experience the R9 Fury has to offer."

ASUS Introduces STRIX GTX 980 Ti with DirectCU III Cooler and a Hefty Overclock

Subject: Graphics Cards | June 30, 2015 - 01:16 PM |
Tagged: overclock, oc, GTX 980 Ti, DirectCU III, asus

ASUS has annouced a new STRIX edition of the GeForce GTX 980 Ti, and this is one massive card in not only size (measuring 12" x 6" x 1.57") but in potential performance as well.

image_1.jpg

First off, there is the new DirectCU III cooler, which offers 3 fans and a much larger overall design than that of the existing GTX 980 STRIX card. And there's good reason for the added cooling capacity: this card has one hefty overclock for a GTX 980 Ti, with a 1216 MHz Base and a whopping 1317 MHz Boost clock in "OC mode". The card's default mode is still quite a bit over reference with 1190 MHz Base and 1291 MHz Boost clocks (a reference 980 Ti has a Base of 1000 MHz and Boost clock of 1075 MHz). Memory with the STRIX 980 Ti is also overclocked, with 7200 MHz GDDR5 in both modes.

Features for this new card from ASUS:

  • 1317MHz GPU boost clock in OC mode with 7200MHz factory-overclocked memory speed for outstanding gaming experience
  • DirectCU III with Patented Triple Wing-Blade 0dB Fan Design delivers maximum air flow with 30% cooler and 3X quieter performance
  • AUTO-EXTREME Technology with 12+2 phase Super Alloy Power II delivers premium aerospace-grade quality and reliability
  • Pulsating STRIX LED makes a statement while adding style to your system
  • STRIX GPU-Fortifier relieves physical stress around the GPU in order to protect it
  • GPU Tweak II with Xsplit Gamecaster provides intuitive performance tweaking and lets you stream your gameplay instantly

The 0dB fans (zero-RPM mode under less demanding workloads) are back with a new "wing-blade" design that promises greater static pressure. Power delivery is also improved with the 14-phase "Super Alloy Power II" components, which ASUS claims will provide 50% cooler thermals while reducing "component buzzing" by up to 2x under load.

The new ASUS STRIX GTX 980 Ti Gaming card hasn't shown up on amazon yet, but it should be available soon for what I would expect to be around $699.
