Details of NVIDIA's next-gen 9800 series of high-end performance graphics cards are beginning to surface. What is known so far is that there will indefinitely be a GeForce 9800 GX2 (dual GPU) card, along with a 9800 GTX and 9800 GT.

According to [H]ardOCP the upcoming GX2 will be around 30% quicker than the 8800 Ultra. The 8800 GTX is expected to perform roughly equal to (if not a bit faster) than the Ultra. XBit Labs also have a short briefing about these upcoming cards here.

Nvidia Corp., the world's largest designer of discrete graphics processing units (GPUs), reportedly plans to update its lineup of expensive graphics cards with at least two new offerings later in the quarter. The most powerful of the novelties will carry two graphics chips, whereas another will feature single-chip designs.

The new top-of-the-range graphics card by Nvidia is called GeForce 9800 GX2 which is based on two yet unknown 65nm graphics chips with 128 unified shader processors inside. The board, according to [H]ard|OCP web-site, will be 30% faster compared to Nvidia GeForce 8800 Ultra and will enable 4-way multi-GPU configurations. The novelty will have 256 stream processors in total, but will rely on driver support to demonstrate its potential, just like any multi-GPU solutions.

Further to the above tidbit, images of the 9800 GX2 have started circulating around the web, and though it may not be the finished product I'm sure it'll turn out pretty much the same. Toms Hardware have exclusive pics of the card in all its glory here.

We know that the 9800GX2 has 2 printed circuit boards (PCBs), as did the 7950GX2 in its time, two graphics processing units (GPUs) using 65 nm nodes (most likely G92s with 128 stream processors), 1 GB of memory (512 MB for each GPU) and two DVI outputs.
