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.

PowerColor (a TUL corporation brand) launched its dual-GPU Radeon HD 7990 V2 graphics card, and this time the card is based on the (recently reviewed) official dual-GPU AMD “Malta” GPU announced at the Games Developers Conference (GDC). The new HD 7990 V2 graphics card features two AMD HD 7970 cards in a Crossfire configuration. That means that the Malta-based card features a total of 4096 stream processors, and a rated 8.2 TFLOPS of peak performance.
The PowerColor HD 7990 V2 joins the company’s existing Devil 13 and HD 7990 graphics cards. The new card sports a triple-fan shrouded heatsink that is somewhat tamer-looking that the custom Devil 13. Other hardware includes 3GB of GDDR5 RAM per GPU clocked at 1500MHz and running on a 384-bit bus (again, per GPU) for a total of 6GB. Both GPUs have clock speeds of 950MHz base and up to 1GHz boost.
The new GPU has a single DL-DVI and four mini-DisplayPort video outputs. PowerColor is touting the card’s Eyefinity prowess as well as its ZeroCore support for reducing power usage when idle. The board has a TDP of 750W and is powered by two PCI-E power connections. In all, the HD 7990 V2 graphics card measures 305 x 110 x 38mm. While PowerColor has not released pricing or availability, expect the card to be available soon and around the same price (or a bit lower than) as its existing (custom) HD 7990.
The full press release can be found here.

We've seen tests of dual 7970s in CrossFire simulating a 7990 and ASUS released the ARES II which was the closest we had until today with the release of the reference HD 7990. There are many reviews to chose from when looking at this new flagship card, such as from a pure performance perspective such as [H]ard|OCP's which did not come out well for AMD's new card. If you are more interested in our new Frame Rating process then there are two reviews to read, one that deals with the 7990 on the publicly available driver and perhaps more interesting is a prototype driver provided to Ryan that is intended to fix Crossfire stuttering on single displays but not for EyeFinity
"Today marks the launch of AMD's Radeon HD 7990. The Radeon HD 7990 is a dual-GPU video card that has its two GPUs down on a single PCB that uses CrossFire to operate the two Radeon HD 7970 GPUs. We will test this video card in the latest games, comparing it to GeForce GTX 680 SLI and Radeon HD 7970 GHz Edition CrossFire. "

The card we have been expecting
Despite all the issues that were brought up with our new graphics performance testing methodology we are calling Frame Rating, there is little debate in the industry that AMD is making noise once again in the graphics field. From the elaborate marketing and game bundles with all Radeon HD 7000 series cards over the last year to the hiring of Roy Taylor, VP of sales but also the company's most vocal supporter.
Along with the marketing though goes plenty of technology and important design wins. With the dominance of the APU on the console side (Wii U, Playstation 4 and the next Xbox), AMD is making sure that the familiarity with its GPU architecture there pays dividends on the PC side as well. Developers will be focusing on AMD's graphics hardware for 5-10 years with the console generation and that could result in improved performance and feature support for Radeon graphics for PC gamers.
Today's release of the Radeon HD 7990 6GB Malta dual-GPU graphics card shows a renewed focus on high-end graphics markets since the release of the Radeon HD 7970 in January of 2012. And while you may have seen something for sale previously with the HD 7990 name attached, those were custom designs built by partners, not by AMD.
Both ASUS and PowerColor currently have high-end dual-Tahiti cards for sale. The PowerColor HD 7990 Devil 13 used the brand directly but ASUS' ARES II kept away from the name and focused on its own high-end card brands instead.
The "real" Radeon HD 7990 card was first teased at GDC in March and takes a much less dramatic approach to its design without being less impressive technically. The card includes a pair of Tahiti, HD 7970-class GPUs on a single PCB with 6GB of total memory. The raw specifications are listed here:
Considering there are two HD 7970 GPUs on the HD 7990, the doubling of the major specs shouldn't be surprising though it is a little deceiving. There are 8.6 billion transistors yes, but there are still 4.3 billion on each GPU. Yes there are 4096 stream processors but only 2048 on each GPU requiring software GPU scaling to increase performance. The same goes with texture fill rate, compute performance, memory bandwidth, etc. The same could be said for all dual-GPU graphics cards though.
