Nvidia Corp. on Tuesday unveiled yet another high-end graphics card that belongs to the GeForce 9-series. The new board does not bring any important new features, but offers performance a little higher compared to what was previously available on its $349 price-point.

Nvidia GeForce 9800 GTX graphics card is based on the well-known code-named G92 graphics processor that is already used on many GeForce 8 and 9 graphics cards and has 128 unified shader processors and offers even higher shader performance than any other previously-released single-chip graphics card by Nvidia. Like all the chips based on the G92, the model 9800 GTX fully supports DirectX 10, hardware-accelerated decoding and post-processing of high-definition video and other up-to-date features.

The two new features that the model 9800 GTX does support rely on multi-GPU SLI technology. The novelty is compatible with 3-way SLI configurations and three GeForce 9800 GTX graphics boards may be installed into one system to render video games at higher speed. In addition, the novelty will support power-saving capability called Hybrid SLI/HybridPower, when functionality of a discrete graphics core/cores may be seamlessly reassigned to integrated graphics core (provided that there is one Nvidia built-in graphics core on the mainboard) and standalone graphics cards switched off in order to save power.

The first breed of the GeForce 9800 GTX graphics cards will all be made under supervision of Nvidia and will have the same clock-speed: 675MHz for chip, 1688MHz for shader processors and 2200MHz for 512MB of GDDR3 memory.

In order to differentiate themselves from competitors, tens of Nvidia’s graphics cards partners plan to provide interesting product bundles, upgrade options and even lotteries. For example, Zogis, a division of JV Logic, offers free T-shirts to those who purchase their GeForce 9800GTX from Newegg.com and raffle off another GeForce 9800 GTX graphics card among them. Meanwhile, companies like BFG Technologies and EVGA offer their customers 90-day trade-up program, when end-users can upgrade their graphics card by only paying the difference between the declared prices.

Nvidia did not release any statements regarding the launch of the new product.
