About a month ago, it surfaces that ASUS was working on a limited-edition extreme high-end graphics accelerator that uses two Radeon HD 5870 GPUs, in essence an overclocked custom-design Radeon HD 5970, called the Republic of Gamers (ROG) Ares. The Ares builds on the legacy of the ROG Mars. It uses two AMD Cypress GPUs with 1600 stream processors, each, core and memory clock speeds on par with that of the Radeon HD 5870 (850 MHz / 1200 MHz), and double the amount of memory (2 GB per GPU, 4 GB on the card).

A CAD drawing of the Ares surfaced on Plaza.fi, which shows a single-PCB accelerator. The cooling design borrows a little from that of NVIDIA's second edition GeForce GTX 295, in having a centrally located blower that drives air onto copper GPU blocks on its either sides. The cooler assembly, however, seems much larger at 2.5 slots' thickness. ASUS also claims that the fan will be quieter on load than AMD's reference HD 5970 leaf-blower. A table given out lists its important specifications, which shows it to have the same clock speeds as the single-GPU Radeon HD 5870 (850/1200 MHz), versus those of the HD 5970 (725/1000 MHz), twice the amount of GDDR5 memory, and results of an internally conducted 3DMark Vantage benchmark which shows a 28.2% increment over the HD 5970 on the Ares. The card is powered by three PCI-Express power connectors (8-pin + 8-pin + 6-pin), and may have significantly higher power draw. It has also been designed for record-setting scores in graphics benchmark competitions. Being a limited edition product, we expect productions in the tens of hundreds only. If the price of ROG Mars is anything to go by, this one will be an expensive product, too.
