GeForce 7800 GTX is a brand new programmable shader architecture, which includes:

  • Twice the performance over the GeForce 6800 Ultra
  • Film quality high dynamic-range lighting support, the must have feature for developers delivering more realism to real-time gaming
  • Second-generation NVIDIA SLI™ technology, for the absolute highest performance and best image quality
  • Second-generation NVIDIA PureVideo™ technology, for home theater quality video on the PC

Q: Is GeForce 7800 GTX a new architecture?
Yes, GeForce 7800 is a revolutionary new architecture built from the ground up to deliver the world's best graphics performance.

Q: What is different in GeForce 7800 GTX when compared to 6800 Ultra?
GeForce 7800 GTX has brand new vertex, pixel and texture units when compared to the GeForce 6800 Ultra. Engineers at NVIDIA were able to pinpoint the key functions bottlenecking shading and graphics performance. By designing and enhancing these functions at the most fundamental level, NVIDIA has brought graphics performance to new levels in the GeForce 7800 GTX.

Q: What are key areas of improvement, as compared to 6800 Ultra?
There are a number of improvements in the GeForce 7800 GTX, including:

  • New vertex, pixel and texture engines
  • The GeForce 7800 GTX has a 24 pipe architecture compared to a 16 pipe architecture of the 6800 Ultra
  • The pipes are more efficient, resulting in a dramatic improvement in shader performance and programmability
  • Increase in clock speeds

Q: How many slots will GeForce GTX-based cards take up in my PC?
One. GeForce 7800 GTX is a single slot solution.

Q: Does GeForce 7800 GTX require an external power dongle?
GeForce 7800 GTX-based graphics cards must be connected to the PCs power supply by a single power dongle.

Q: When can I buy GeForce 7800 GTX?
GeForce 7800 GTX-based graphics cards are available today from our add-in-card partners. You can find them on www.newegg.com and www.zipzoomfly.com.

Q: How much will GeForce 7800 GTX cost?
NVIDIA does not set retail pricing, however, we anticipate the street price will be around $599.

Q: How many transistors does the GeForce 7800 GTX have?
302 million.

Q: Does GeForce 7800 GTX support SLI?
Absolutely, SLI is a must-have-feature for any enthusiast's board and the GeForce 7800 GTX is NVIDIA's new flagship card for SLI.

Q: Does GeForce 7800 GTX support more than two GPUs in SLI mode?
No - not right now.

Q: What is new in the video processor?
We've taken NVIDIA PureVideo technology to the next level by adding support for some new algorithms with GeForce 7800 GTX. With those new algorithms, we now support de-interlacing with HD resolutions up to 1080i. In addition, we've also added support for inverse 2:2 pulldown. Because the video processors are programmable as new video formats come out we will be able to support them through driver updates. In addition, the GeForce 7800 GTX supports WMV-HD decode acceleration that can offload video decoding from the CPU onto the GPU, giving users up to 40% gains in CPU utilization.

Q: With the introduction of the GeForce 7800 GTX, does this mean you are discontinuing the GeForce 6 series?
No. The GeForce 7800 GTX will be NVIDIA's new flagship GPU, replacing the GeForce 6800 Ultra at the top of our product line. The other GeForce 6 Series GPUs including the GeForce 6800 GT and Standard, will remain in their respective segments.

Q: How long will the GeForce 6 series be available for purchase?
The GeForce 6 Series GPUs will remain in their respective segments, and will be offered through the end of this year.

Q: Is there a GeForce 7800 Ultra?
GeForce 7800 GTX is our top of the line. We had so much positive response for the GT SKU (single slot, great performance) that we wanted to build upon that success and brand. GeForce 7800 GTX takes NVIDIA's high end performance offering to the next level.

Q: Will there be a 512MB version?
While the GPU can support up to 512MB of RAM, it's up to our customers and consumer demand to bring one to market.

Q: Will you use HSI to make AGP-based GeForce 7800 boards?
We are not disclosing plans for AGP at this time, but that is certainly possible with the flexibility of our HSI chip.

Q: How many pipes are in GeForce 7800 GTX?
24 pixel pipes and 8 vertex pipes.

Q: What kind of memory does GeForce 7800 GTX use?
GeForce 7800 GTX uses high-speed 256-bit GDDR3.

Q: What is the core clock on GeForce 7800 GTX?
430MHz

Q: What power supply does it require?
Current recommendations are 350W for single, 500W for SLI.

Q: What is the memory clock on GeForce 7800 GTX?
600MHz

Q: Have you changed the way you do AA?
GeForce 7800 GTX has some new features that we've added to our AA engine, such as support for transparency supersampling and multisampling. This advanced feature is a technique used where-by the undesirable visible aliasing inside of a polygon is minimized by using the transparency settings in a given texture. The improvement in 3D image quality can be most visible when viewing outdoors scenes. Basically all objects that appear thin (and or repetitive) benefit from this new technology. Trees, plants, and fences are great examples. This can be enabled by using either of two methods: multisampling (Superior Performance) or supersampling (Superior Quality).
