Chinese graphics card maker Yeston, has already accustomed us to its solutions based on highly customized designs, so it comes as no surprise that the company is now working on developing a special version of the Radeon HD 6990.

The card appears to be still in its early stages as the only thing that Yeston has to show for itself is a printed circuit board, which bears no sort of chips of any other components.

However, despite the ongoing development, the PCB does manage to show us a few of the features that we should come to expect from this card.

For starters, the most noticeable addition brought by Yeston to the reference HD 6990 is the improved VRM design, that now uses a total of 12 phases for powering the components installed on the card, but the video output configuration was also changed for the board to include two DVI ports, two mini DisplayPort outputs and an HDMI connector.

Just as the reference Radeon HD 6990, the graphics card gets its power through two PCI Express 8-pin connectors, which are placed in the back of the PCB.

Sadly, these are all the features that can be spotted right now, but it's safe to assume that Yeston will also include a series of more advanced features on this custom HD 6990, such as dual-BIOS support.

The Radeon HD 6990 is AMD's fastest graphics card to date as it packs two Cayman XT cores on the same PCB and features 3072 stream processors, 192 texturing units, 64 ROP units and a pair of 256-bit wide memory interfaces that are linked to 4GB of GDDR5 video buffer.

Its two cores are clocked at 830MHz, but the card also features a special switch which enables users to run it into the so-called AUSUM mode that overclocks the GPUs to 880MHz. (Via Expreview)
