Q: What are you announcing today?
We are launching the new NVIDIA® GeForce Go 7800 GTX, the flagship of the NVIDIA mobile graphics processing unit (GPU) product line for the notebook market.
Q: What is GeForce Go 7800 GTX?
GeForce Go 7800 GTX represents a culmination of groundbreaking visual effects technologies: NVIDIA PureVideo technology, Microsoft® DirectX® 9.0 Shader Model 3.0, advanced antialiasing algorithms, and much more. In addition, an all new NVIDIA CineFX engine, CineFX 4.0, delivers unparalleled horsepower with twice the floating point shading power of previous-generation products. To better address power management, we've introduced a new version of our NVIDIA PowerMizer technology. Raising the bar for performance, battery life, visual effects, image quality, and video functionality, the GeForce Go 7800 GTX GPUs power the most extreme notebook PC experience.
Q: Does GeForce Go 7800 GTX support ShaderModel 3.0?
Yes, the NVIDIA GeForce Go 6 and GeForce Go 7 GPUs remain the only mobile GPUs certified for the latest version of Microsoft DirectX 9 (Shader Model 3.0), the base functionality for all next-generation gaming consoles and PCs. DirectX 9 Shader Model 3.0 allows PCs to render the most intense visual effects for today's hottest games.
Q: Does GeForce Go 7800 GTX support HDR Lighting?
Yes, the GeForce Go 7800 GTX introduces a new texture core that accelerates the floating point filtering necessary for high dynamic-range (HDR) rendering, a must-have feature for today's hottest games.
Q: Is GeForce Go 7800 GTX a new architecture or a spin for the NV4x?
GeForce Go 7800 GTX is a revolutionary new architecture built from the ground up to deliver the world's best graphic performance.
Q: How does GeForce Go 7800 GTX differ from GeForce Go 6800 Ultra?
GeForce 7800 GTX has a brand new vertex, pixel and texture units. Engineers at NVIDIA were able to pinpoint the key functions that bottleneck 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 Go 7800 GTX.
Q: What are key improvements, as compared to GeForce Go 6800 Ultra?
A number of improvements are offered on the GeForce 7800 GTX, including
- The pipe architecture increased from 12 to 24.
- Each pipe has more computational horsepower, resulting in faster performance per pipe.
- The shader performance and programmability dramatically improved.
Q: When can I buy a notebook with GeForce Go 7800 GTX?
GeForce Go 7800 GTX GPUs are available today from Dell, Sager, Falcon NorthWest, Voodoo PC, ProStar, and others (you can find them online on nvidia.com).
Q: What is new in the video processor?
We've taken PureVideo to the next level by adding support for some new algorithms with GeForce Go 7800 GTX. With those new algorithms, we now support de-interlacing with HD resolutions up to 1080i. In addition, we've added support for inverse 2:2 pull-down. The video processors are programmable, so as new video formats come out we will be able to support them through driver updates. In addition, GeForce Go 7800 GTX supports WMV HD decode acceleration that can offload video decoding from the CPU onto the GPU, reducing CPU utilization by about 40 percent.
Q: How much memory will the new GPU support?
GeForce Go 7800 GPUs can support up to 512 MB of local graphics memory.
Q: Tell me more about PowerMizer.
All this additional performance is based on the new GeForce Go 7 architecture. Remarkably, this additional performance is achieved in the same thermal and power budget as the previous generation of GPUs. Note that most of our launch platforms are using the same thermal solution as the GeForce Go 6800 Ultra. This is possible because of the massive increase in performance per watt in the GeForce Go 7 architecture, and because of refinements in NVIDIA's acclaimed PowerMizer technology that generate less heat and maximize battery life.
Q: How much less heat? And how much battery life do you save?
GeForce Go 7800 GTX delivers up to 50 percent more performance in the same thermal budget that GeForce Go 6800 Ultra delivered. This is important because it means users get 50 percent more performance in the same form factor with this new GPU.
Q: Does the new 7-series Go GPU support MXM?
Of course the 7-series supports MXM. The MXM graphics interface reduces the length of the design cycle for notebook platforms, facilitating faster time to market for the latest notebook graphics and enabling multiple configure-to-order solutions and price points.
Q: How many pipes does GeForce Go 7800 GTX have?
The GeForce Go 7800 GTX has 32 pipes-24 pixel pipes and 8 vertex pipes.
Q: How many pixel shading engines does GeForce Go 7800 have?
It has 24 pixel shader units.
Q: How many vertex shading engines does GeForce Go 7800 have?
It has 8 vertex shader units.
Q: What kind of memory does GeForce Go 7800 use?
GeForce Go 7800 supports DDR1, DDR2, and GDDR3.
Q: What is the core clock on GeForce Go 7800?
The core clock is 400 MHz (maximum clock; specific notebooks may vary).
Q: What is the memory clock on GeForce Go 7800?
The memory clock is 550 MHz (maximum clock; specific notebooks may vary).
Q: Have you changed the way you do AA?
The NVIDIA Go GeForce 7800 implements the same new features that we've added to our desktop product, such as support for transparent supersampling and multisampling. Nearly all games with outdoor scenes use textures with transparency to model fine objects (like tree leaves, grass, chain link fences, and other fine geometric detail). Traditional antialiasing does not smooth transparent textures at all. The GeForce Go 7 architecture is the first to apply antialiasing to these fine details.
Q: Does GeForce Go 7800 support Vista/Longhorn?
Yes, in fact NVIDIA has provided Vista drivers to OEMs and Microsoft for GeForce Go 4, GeForce Go 5, and GeForce Go 6-enabled notebooks. See your OEM for Vista beta support.
Q: Does NVIDIA support notebooks with UDA (downloadable drivers)?
Yes, NVIDIA has always been able to support notebooks with the unified driver on nvidia.com/nzone.com, but our Tier 1 OEM partners have always required that we direct customers to their Web sites and disable support for their notebooks in our unified driver. However, NVIDIA does support OEMs/SBs who request that their notebooks be enabled in our unified driver. For example, most of our launch partners are enabled on our Web unified drivers (Sager, Falcon NW, Voodoo PC, ProStar, and others).
