Advanced Micro Devices never actually released a Radeon HD 7990 video card, but that hasn't stopped its OEMs from launching dual-GPU boards independently. ASUS has just released the latest such card.
ASUS appears undaunted by the fact that the Sea Islands series have essentially been formally introduced by Advanced Micro Devices and, thus, the Radeon HD 8000 graphics card series is almost upon us.
The company went ahead and introduced the Ares II video board, equipped with two Pitcairn graphics processing units.
Since AMD never introduced a Radeon HD 7990, even though it did launch a Radeon HD 6990 a while ago, the HD 7990 doesn't actually exist as a brand.
As such, ASUS has named the Ares II a dual-HD 7970 (HD 7970 is the most powerful single-GPU adapter in AMD's lineup at this time).
Ares II has 6 GB of GDDR5 VRAM memory, a 20-phase VRM, a dual-slot water cooler (120 mm radiator, two fans in a push-pull configuration).
The model on display at CES 2013 (Consumer Electronics Show), in Las Vegas, Nevada reveals four full-size DisplayPort as well, plus two DVI-D connectors.
In other words, it is possible to set up a complete six-monitor Eyefinity multi-display gaming and film theater with this board alone.
As for clock speeds, the GPUs run at 1,100 MHz and the memory at 1650 MHz (6.6 GHz effective).
ASUS intends to start selling the Ares II dual-HD 7970 video adapter soon, but the price won't be doing it any favors: $1,500 / 1,147-1,500 Euro, three times as much as a single HD 7970 board.
The company is well aware of this, which is why it will only do a limited run (1000 units will be made, each with a serial number).
We can only wonder what six special screens, like Samsung's new curved OLED TVs, would look like in Eyefinity 6 mode.
