The latest installment in the ASUS ARES series of ultra-powerful, limited-edition graphics cards has been announced, and the Ares III is set to be the “world’s fastest” video card.
The dual-GPU powerhouse is driven by two “hand-selected” Radeon Hawaii XT GPUs (R9 290X cores) with 8GB of GDDR5 memory. The card is overclockable according to ASUS, and will likely arrive factory overclocked as they claim it will be faster out of the box than the reference R9-295x2. The ARES III features a custom-designed EK water block, so unlike the R9 295x2 the end user will need to supply the liquid cooling loop.
ASUS claims that the ARES III will “deliver 25% cooler performance than reference R9 295X designs“, but to achieve this ASUS “highly” recommends a high flow rate loop with at least a 120x3 radiator “to extract maximum performance from the card,” and they “will provide a recommended list of water cooling systems at launch”.
Only 500 of the ARES III will be made, and are individually numbered. No pricing has been announced, but ASUS says to expect it to be more than a 295x2 ($1499) - but less than a TITAN Z ($2999). The ASUS ROG ARES III will be available in Q3 2014.

Tagged: r9 295x2, powercolor, hawaii, dual gpu, devil 13
PowerColor has been teasing a new graphics card on its Facebook page. The photos show a macro shot of the Devil 13 logo along with captions hitting at the new card being a dual GPU monster including one caption referring the upcoming Devil 13 as a "dual beast."
PowerColor's previous Devil 13 branded graphics card was the Radeon HD 7990 Devil 13 which contained two HD 7970 "Tahiti" GPUs on one PCB. Coincidentally, AMD recently launched a new dual GPU reference design based around two R9 290x "Hawaii" GPUs called the R9 295x2. It is still rumor and speculation at this point, but the timing and leaked photos seem to point squarely at the upcoming Devil 13 card being the first air cooled custom R9 295x2!
Adding credence to the rumors, leaked photos have appeared online with a PCB backplate that appears to match the backplate shown in the official teaser photo. The leaked photos show an absolutely beastly triple slot graphics card that places two GPUs in CrossFire on a single custom PCB powered by four 8-pin PCI-E power connectors and cooled by a gargantuan HSF comprised of an aluminum fin stack and multiple large diameter copper heatpipes along with three fans. The cooler and PCB are reinforced with brackets and a metal backplate to help keep the air cooler in pace and the PCB from bending.
If the rumors hold true, PowerColor will be unveiling the first air cooled dual GPU R9 295X2 graphics card which is an impressive feat of engineering! Using four 8-pin PCI-E power connectors definitely suggests that aftermarket overclocking is encouraged and supported even if PowerColor does not end up factory overclocking their dual GPU beast.
For reference, the stock AMD R9 295X2 features two full Hawaii GPUs with 5,632 stream processors clocked at up to 1018 MHz interfaced with 8GB of total GDDR5 memory over a 512-bit bus (each GPU has 4GB of memory and a 512-bit bus). AMD rates this configuration at 11.5 TFLOPS of single precision performance. The reference R9 295X2 has a 500W TDP and uses two 8-pin PCI-E power connectors.
Please excuse me while I wipe the drool off of my keyboard...
Stay tuned to PC Perspective for more details on the mysterious dual GPU Devil 13 from PowerColor!
In the meantime, check out our full review of the R9 295X2 (and the Hawaii architecture) and what happens when you put two R9 295X2s in Quad CrossFire into a single system for 4K gaming goodness!

NVIDIA unveiled the GeForce GTX TITAN Z at the GPU Technology Conference last month, and the cards will be for sale soon from various partners. ASUS will be one of the first AIB partners to offer a reference TITAN-Z.
The ASUS GTX TITAN Z pairs two full GK110-based GPUs with 12GB of GDDR5 memory. The graphics card houses a total of 5,760 CUDA cores, 480 texture manipulation units (TMUs), and 96 ROPs. Each GK110 GPU interfaces with 6GB of GDDR5 memory via a 384-bit bus. ASUS is using reference clockspeeds with this card, which means 705 MHz base and up to 876 MHz GPU Boost for the GPUs and 7.0 GHz for the memory.
For comparison, the dual-GPU TITAN Z is effectively two GTX TITAN Black cards on a single PCB. However, the TITAN Black runs at 889 MHz base and up to 980 MHz GPU Boost. A hybrid water cooling solution may have allowed NVIDIA to maintain the clockspeed advantage, but doing so would compromise the only advantage the TITAN Z has over using two (much cheaper) TITAN Blacks in a workstation or server: card density. A small hit in clockspeed will be a manageable sacrifice for the target market, I believe.
The ASUS GTX TITAN Z has a 375W TDP and is powered by two 8-pin PCI-E power connectors. The new flagship dual GPU NVIDIA card has an MSRP of $3,000 and should be available in early May.

Early last month, AMD launched a new flagship dual GPU graphics card called the Radeon R9 295X2. This new card features two Hawaii-based GPUs paired with 8GB of GDDR5 memory. Since the launch, several partners have come forward with reference cards of their own. One piece of the "world's fastest graphics card" puzzle that has been missing, until now, is a vendor daring enough to take the beastly R9 295X2 and push it even further by offering up a factory overclocked edition. It looks like Sapphire is the first to attempt such a feat by offering up the factory overclocked Sapphire R9 295X2 OC.
The upcoming Sapphire card will join the existing reference design R9 295X2 and ratchets up both the GPU and memory clockspeeds. Sapphire is clocking both Hawaii GPUs at up to 1030 MHz and running the 8GB of GDDR5 memory at 5.2 GHz. These factory overclocks are modest from a numerical standpoint, but considering cards running at stock clocks of 1018 MHz for the GPU and 5.0 GHz for the memory are already pushing a 500W TDP and over the ATX PSU spec, seeing any overclock is notable.
In all, we are looking at 5,632 stream processors (Hawaii architecture), 128 ROPs, and 352 TMUs. Each GPU uses a 512-bit bus to 4GB of graphics memory. This factory overclocked graphics horsepower rounds out to a smidgen more than 11.5 TFLOPS of single precision performance.
Sapphire is utilizing the same hybrid heatsink design as the reference cards which uses a centered fan and fin stack along with a AIO water cooler with a 120mm radiator.
Sapphire has not released pricing or availability on the overclocked model, but the stock-clocked R9 295X2 has an MSRP of $1,499. You can expect the R9 295X2 OC to come in at a premium, especially considering it is the first factory overclocked version that should hit the streets.
I'm excited to see this card come to market and push the boundaries of performance.
In the meantime, Ryan got a bit crazy with two stock R9 295X2 cards in quad crossfire and two power supplies. If you've got a few grand burning a hole in your pocket (or only wish you did), see what such a drool-worthy setup can get you in terms 4K gaming at PC Perspective!

Sapphire appears to be preparing to unleash a factory overclocked dual GPU card called the Radeon HD 7990 Atomic. EXPReview managed to uncover several photos and specification details of the upcoming graphics card. It is quite an impressive card, that features a custom PCB, beefy power delivery electronics, 6GB of total GDDR5, and (best of all) two AMD Radeon HD 7970 GPUs cooled by a full cover closed loop water cooler!
The Sapphire HD 7990 Atomic is based around a custom 12-layer PCB. The card also features an 18-phase VRM, 50A chokes, LFPAK MOSFETS, and Tantalum capacitors. Sapphire has divided the total 18-phase VRM up such that each GPU and 3GB of memory gets 6+2+1 power phases. Of course, the HD 7990 Atomic uses two AMD Radeon HD 7970 GHz Edition GPUs for a total of 4,096 stream processors.
Sapphire has not released clockspeed information, but it should be overclocked significantly beyond the company’s existing dual gpu 7990 card’s base and boost clockspeeds of 950 MHz and 1000 MHz.
Other features include a PLX PEX8747 PCI-E 3.0 bridge chip that connects the two 7970 GPUs together, a dual BIOS switch that will allow users to run the 7990 at stock or at overclocked speeds, and a single crossfire connector to enable quad-Crossfire multi-GPU setups. The graphics card is powered by three 8-pin PCI-E power connectors. Finally, it provides six mini-DisplayPort video outputs.
In order to effectively cool the factory overclocked card, Sapphire is bundling a pre-installed self-contained liquid cooler. The closed loop cooler consists of a full cover water block on the HD 7990 Atomic, a 240mm radiator with two 120mm fans, and a combination pump and reservoir that fits within a 5.25” optical drive bay.
Naturally, how much this card will cost and where it will be available is still unknown. With that said, ChipLoco indicates that the card is coming sometime within the “next few weeks.” The extent of the factory overclock is also unknown. It is definitely a high end card worthy of enthusiasts and overclockers. Unfortunately, it utilizes a custom PCB, so it may be difficult to find alternative blocks should users wish to integrate it into their existing custom water loops.

Now that AMD’s dual-gpu Malta graphics card is official, cards from Add-In Board (AIB) partners are starting to roll in. One such recently announced card is the XFX Radeon HD 7990 card. The XFX card is based on the reference AMD design, which includes two Radeon HD 7970 GPUs in a Crossfire configuration.
The two GPUs can boost up to 1GHz clock speeds and feature a total of 4096 stream processors, 256 texture units, 64 ROPs, and 8.6 billion transistors. The card also includes 3GB of GDDR5 memory per GPU running off a 384-bit bus. It supports AMD’s Eyefinity technology and offers up one DL-DVI and four mini-DisplayPort video outputs.
The XFX HD 7990 uses the reference AMD heatsink as well, which includes a massive aluminum fin stack with five copper heatpipes that run the length of the heasink and directly touch the two 7970 GPUs. Three shrouded fans, in turn, keep the heatsink cool.
The dual-GPU monster is eligible for AMD’s Never Settle bundle which includes eight free games. With purchase of the HD 7990 (from any eligible AIB), you get free key codes for the following games:
- Bioshock Infinite
- Crysis 3
- Deus Ex: Human Revolution
- Far Cry 3
- Far Cry 3: Blood Dragon
- Hitman: Absolution
- Sleeping Dogs
- Tomb Raider
The XFX press release further assures gamers that the card can, in fact, play Crysis 3 at maximum settings at a resolution of 3840 x 2160. The company did not mention pricing, however.
For those interested in AMD’s new Malta GPU, check out our review as well as how the card performs when paired with a prototype AMD driver that seeks to address some of the frame rating issues exhibited by AMD's Crossfire multi-GPU solution.

ASUS has just announced it's Limited Edition ROG ARES II Graphics card, and boy is it a doozy!
Dual AMD Radeon 7970 GPU's clocked at 1100 MHz are paired with 6 GB of DDR5 running at a speedy 1650 MHz memory clock. This monster needs 3 8 Pin power connectors from the minimum recommended 850 watt power supply that can push at least 42 Amps on the 12V rail.
The ARES II will come with a 'hybrid cooling setup' that includes a custom cooler using both liquid and air cooling. A closed-cycle liquid system with dual 120 mm fans and a radiator block cool the GPU while an 80mm 'dust-proof' fan gives additional cooling for the memory, power and other critical components. ASUS is claiming that the cooling setup will keep everything stable even under full load and can achieve 13% more performance while running 30C cooler temperatures when compared to a reference GTX 690.
Detailed Specifications include:
2 x AMD Radeon™ HD 7970 GHz Edition
PCI Express 3.0 x 16
1100MHz (base clock: 1050MHz)

Tagged: venus, Sea Islands, radeon hd 8990, hd 8990, dual gpu, 28nm
Earlier this year rumored specifications for AMD’s upcoming HD 8000-series graphics cards leaked to the Internet. Details on the 8800 and 8900 series cards have since been revealed along with rumored/estimated clock speeds and pricing. One card that has, until now, remained an unknown is the dual-GPU Radeon HD 8990, however.
The existence of a dual GPU Sea Islands card has been especially suspect as a result of the ever-elusive Radeon 7990 and its almost-certain cancellation in an official AMD-branded form. On the other hand, a road map leaked by BitDreams.se and discovered by Maximum PC seems to suggest that an HD 8990 is at least being considered.
The Radeon HD 8990 follows the dual GPU traditions of its predecessors by combining two 8970 GPUs onto a single PCB. That means, if the previously leaked 8970 specifications hold true, the 8990 graphics card will have 5,120 stream processors, 320 texture units, 96 ROPs, and a 384-bit memory bus for each GPU. The card will have between 6 and 12GB of GDDR5 memory (3GB-6GB per GPU). The dual GPU card will have a maximum TDP of 375W and will come with slightly lower GPU core and memory clockspeeds compared to two individual 8970 cards. The GPU will be clocked at 950MHz and the memory will be clocked at 1250MHz. The single GPU Radeon 8970 will come clocked at 1050MHz core and 1500MHz memory, however.
|Radeon HD 7870||Radeon HD 8870||Radeon 7950||Radeon 8950||Radeon HD 7970||Radeon HD 8970||Radeon HD 7990||Radeon HD 8990|
|Die Size||212mm^2||270mm^2||365mm^2||~400mm^2||365mm^2||~ 400mm^2||365mm^2 x2||~400mm^2 x2|
|TMUs||80||112||112||144||128||160||128 x 2||160 x 2|
|ROPs||32||32||32||32||32||48||32 x 2||48 x 2|
|Memory Interface||256-bit||256-bit||384-bit||384-bit||384-bit||384-bit||384-bit x2||384-bit x 2|
|Bandwidth||153.6 GB/s||192 GB/s||240 GB/s||322 GB/s||288 GB/s||322 GB/s||288 GB/s x 2||600 GB/s (total)|
The dual gpu 8990 card, as well as the rest of the 8000 series will support DirectX 11, Shader Model 5.0, and OpenGL 4.2. Bit Dreams lists the maximum single and double precision performance at 10.2 and 3 TFLOPS respectively, making this a rather powerful card that is not quite the same performance as two 8970s but will take up less space. Interestingly, the card would be noticeably faster than AMD’s FirePro S10000 card (essentially two 7950 gpus) at 1.48 TF double precision and 5.91 TF single precision. That would suggest that Venus is much more efficient than Tahiti, if the numbers turn out to be true.
The card will allegedly be released sometime in the second quarter of 2013 (Q2’13). Pricing is likely to be around $1,000 but so far pricing information has not leaked. Even taking these numbers with a spoon of salt, a dual GPU 8000 series card is sure to be welcome by enthusiasts. Here’s hoping it ends up being released (unlike the 7990) and is as fast as it’s rumored to be!
