NVIDIA GeForce GTX 200 GPUs
Two Personalities, One GPU
Built with over 1.4 billion transistors, NVIDIA’s GeForce GTX 280 and 260 GPUs are the largest
and most complex GPUs ever created. Featuring 240 shader processors, 80 texture processors,
and 1 GB of frame buffer, the GeForce GTX 280 offers peerless performance in all of today’s
hottest titles. But it is more than just the world’s fastest GPU.
Thanks to NVIDIA’s CUDA technology, the GeForce GTX 280 is also an immensely powerful,
many-core, parallel processor. When operating in computing mode, the GeForce GTX 280
becomes a fully programmable multiprocessor with 240 cores, on-die shared memory, random
read and write capability, and 1 GB of dedicated memory. In computing mode, the GeForce GTX
280 turns an ordinary PC into a miniature supercomputer, providing almost one teraflop of
horsepower for advanced visual computing, video transcoding, physics acceleration, and
scientific computing.
Beyond Gaming
With over 70 million CUDA-enabled GeForce 8 and 9 Series GPUs shipped to market, numerous
rich-media and visual-computing applications are becoming CUDA-enabled. These applications
are joining the ever-growing trend of apps that are enjoying phenomenal performance speedups
that started with high-end professional and scientific applications upon the initial release of CUDA.
GPU-Powered Video Transcoding
Transcoding is one of the most time-consuming desktop
applications today. Transcoding a movie from one format to
another can take half a day, making the process extremely
unfriendly to the end user. Faster CPUs can reduce the time by
minor increments, but the final waiting time is still many hours.
With CUDA technology, video transcoding time can be cut by up
to 18×, reducing waiting time from hours to minutes. The
RapidHD video transcoder from Elemental Technologies uses
CUDA to achieve this exact feat, allowing video to be quickly
converted from one format to another, making them easier to
share and enjoy.
GPU Powered Folding@Home
Stanford University’s Folding@Home client allows the home PC
user to perform protein simulations to help scientists better
understand protein folding, misfolding, and related diseases.
Now powered by CUDA, Folding@Home will tap into the power
of the GPU, allowing tens of millions of GeForce users advance
medical science with this distributed program. Even if 1% of
NVIDIA users participated in Folding@Home, it would offer a
stratospheric increase in the total computing power of the
Folding@Home distributed cluster.
Industry wide support for CUDA
Countless math-intensive applications benefit from CUDA and the power of the GPU. Figure 1
shows the incredible speedups achieved for both consumer and professional applications.
Appendix A lists references and details for these applications.
Figure 1. GPU Speedups Versus CPU

Gaming Beyond
Today’s games have great visuals, but they do not behave with great realism. Animation is often
unconvincing, particle effects do not take into account of physics, and geometry is static and
unchanging. GeForce GTX 200 GPUs take gaming beyond static realism, into dynamic realism.
Dynamic Realism
While prior-generation GPUs could deliver real-time images that appeared true-to-life in many
cases, frame rates could drop to unplayable levels in complex scenes with significant animation,
numerous physical effects, and multiple characters. The combination of the sheer shader
processing power of GeForce GTX 200 GPUs and NVIDIA’s new GPU PhysX technology facilitates
many new high-end graphics effects including:
‰
Convincing facial animation
‰
Multiple ultra-high polygon characters in complex environments
‰
Advanced volumetric effects like smoke, fog, and mist
‰
Fluid and cloth simulation
‰
Fully simulated physical effects such as live debris, explosions, and fires.
‰
Physical weather effects such as accumulating snow and water, sand storms,
soaking, drying, dampening, overheating, and freezing
‰
Better lighting for dramatic and spectacular effect, including ambient occlusion,
global illumination, soft shadows, color bleeding, indirect lighting, and accurate
reflections.
In Figure 2 below, you can see a comparison of our previous “Adrianne” demo used to highlight
the capabilities of the GeForce 8-series GPUs to our new Medusa demo used to demonstrate the
power of the GeForce GTX 200 GPUs.
Adrianne was a single, complex character existing primarily in a cubemap environment. Priorgeneration GPUs only had enough horsepower to render a single complex character, like
Adrianne, in a scene. With the GeForce GTX 200 GPUs, we have enough horsepower to render
two characters (each more complex than Adrianne) within an incredibly complex environment all
on one GPU.
5
Figure 2. Facial Expressions in Medusa
Numerous "blendshapes" are used in the Medusa demo. Blendshapes are the facial poses that
are combined to produce facial expressions in animation. Hollywood movies can use a hundred or
more of these blendshapes per character to capture all the nuances of human expression.
Previous demos like Adrianne were able to maintain about 25-30 blendshapes with only five active
in any individual frame. In the Medusa demo, the Medusa and warrior characters each have 130
blendshapes with over 30 active in an individual frame. Looking at Adrianne, you'll notice her
expressions were a bit "plastic" looking. She had a few extreme expressions of happy, sad,
puzzled, etc., but the Medusa characters show a much broader range of emotion. We can now
create scenes where the characters are truly acting.
We used a key DirectX 10 feature called “stream out” extensively in Medusa. When using the
same model several times in the same frame, stream out allows processing the geometry for the
model once, streaming it out to local video memory, and then reusing the processed geometry
over and over. The characters in Medusa must be rendered several times in a single frame,
including renders for shadow passes, and blur passes for skin rendering. Stream out relieves us
from having to re-process the same geometry multiple times for each pass, which reduces the
geometry processing workload and allows us to apply the remaining horsepower to shading
processing.
Medusa also fully utilizes the DirectX 10 feature called "geometry shading," where geometry can
be created by the GPU. Geometry shading is used for the "stone effect" where the stone grows up
over the form of the warrior. If you observe the demo in wireframe mode, you can see new
triangles (geometry) being created along the leading edge of the growing stone.
Thanks to the power of GeForce GTX 200 GPUs, blendshapes can be used extensively and, in
conjunction with geometry shading and stream out, allow for greatly improved dynamic realism.
NVIDIA PhysX Technology
Delivering physics in games is extremely compute-intensive and based on a set of physics
algorithms that require tremendous amounts of simultaneous mathematical and logical
calculations.
NVIDIA’s PhysX™ technology provides a powerful, real-time physics engine used in numerous
leading edge PC and console games. PhysX has been incorporated into over 150 games, is used
6
by more than 10,000 registered users, and is supported on Sony Playstation 3, Microsoft Xbox
360, Nintendo Wii, and the PC.
The PhysX API is designed to be accelerated by powerful processors with numerous processing
cores, such as the GeForce GTX 200 GPUs. In fact, all NVIDIA CUDA-enabled GPUs such as the
70 million already shipped GeForce 9 and GeForce 8 Series GPUs will support PhysX. Combined
with powerful GPUs, PhysX provides an exponential increase in physics processing power that
takes gaming to a new level, delivering rich, immersive physical gaming environments with
features such as:
‰
Explosions that cause dust and collateral debris
‰
Characters with complex, jointed geometries for more life-like motion and interaction
‰
Spectacular new weapons with incredible effects
‰
Cloth that drapes and tears naturally
‰
Dense smoke and fog that billow around objects in motion
See the PhysX FAQ for more details: http://www.nvidia.com/object/physx_faq.html
SLI
The GeForce GTX 200 GPUs provide 50-100% more performance over prior-generation GPUs,
permitting increased frame rates and higher visual quality settings at extreme resolutions,
delivering a truly cinematic gaming experience.
Support for the new DisplayPort interface allows resolutions beyond 2560 × 1600, and 10-bit color
support permits up to a billion different colors on screen (driver, display, and application support
is also required). Note that prior-generation GPUs included internal 10-bit processing, but could
only output 8-bit component colors (RGB). GeForce 200 GPUs permit both 10-bit internal
processing and 10-bit color output.
NVIDIA’s SLI technology is the industry’s leading multi-GPU technology, giving you an easy, lowcost, high-impact performance upgrade. PC gaming simply doesn’t get any faster or more realistic
than running GeForce GTX 280 boards in SLI mode on the latest nForce® motherboards.
Two flavors of SLI are supported by the initial GeForce GTX 200 GPUs:
‰
Standard SLI (two GPU boards), which typically boosts supported game
performance by 60-90% and permits higher quality settings
‰
3-way SLI, which provides even higher frame rates and permits higher quality
settings for the ultimate experience in PC gaming when connected to a high-end,
high-resolution monitor.
The bottom line is that GeForce GTX 200 GPUs process and display complex DirectX 10 and
OpenGL game environments with amazing cinematic effects and high frame rates at extreme
high-definition resolutions.

Introducing GeForce GTX 200 GPUs
Implementing NVIDIA’s second-generation unified visual computing architecture, the new GeForce
GTX 280 and GeForce GTX 260 graphics boards are members of the GeForce GTX 200 GPU
family and include the powerful new GT200 GPU, providing the ultimate visual computing and
extreme HD gaming experience. Numerous application areas are greatly enhanced and
accelerated by the GeForce GTX 200 GPUs, including gaming, physics, rich media encoding, HD
video playback, image processing, and High-Performance Computation to name a few.
GeForce GTX 200 GPUs include a number of very significant architectural enhancements over the
prior generation, and they continue NVIDIA’s trend of continuous improvement of architectural
efficiency as exemplified by increased performance per watt and performance per square
millimeter of GPU die area.
With its 240 processing cores and 1GB of frame buffer memory at a suggest retail pricing of $649,
a stock-clocked GeForce GTX 280 board will deliver 1.5x performance improvement on average
over high-end GeForce 8 and GeForce 9 series single-GPU graphics boards.
The $449-based GeForce GTX 260 targets price/performance conscious enthusiasts and includes
a reduced number of processing cores (192) and lower frame buffer size (896MB), but still permits
many top 3D games to be played in all their glory.
Users can configure two or three GeForce GTX 200 GPU boards in SLI mode, using appropriate
nForce chipset-based motherboards, delivering the highest frame rates, highest resolution, and
best 3D visual quality possible today. The new GPUs incorporate advanced power and thermal
management for optimal acoustics, power, and performance based on usage. Dynamic clock and
voltage scaling based on workload, intelligent clock gating, and Hybrid Power support help keep
the electric bill at bay, while lowering heat and noise output.
The GT200 GPU is manufactured using TSMC’s 65 nm fabrication process. Built with 1.4 billion
transistors, it is the largest, most powerful, and most complex GPU ever made, and operates well
within power and heat margins required in enthusiast PCs.
Optimized PC and Heterogeneous
Computing
GPUs are the most important processors in the new era of visual computing. Powerful GPUs such
as the GeForce GTX 200 GPU family are necessary to run intensive DirectX 10-based 3D games
like Crysis at high quality and high resolution settings. Very capable GeForce 8 and 9 series
integrated and midrange GPUs must be employed to obtain stutter-free high-definition video
playback on the PC, while simultaneously displaying the Aero 3D user interface of Windows Vista.
Users and system vendors are steadily realizing that the proper balance of CPU and GPU power
in a PC configuration is essential for the best user experience and optimal price-to-performance
ratio. We refer to such proper CPU and GPU balance as the “optimized PC”.
Optimized PC configurations are based on the concept of “heterogeneous computing”, where the
appropriate processor is applied to the tasks that it can process the fastest and with the highest
quality. Configuring a system with a lower-cost CPU and using the savings to upgrade to a higherend GPU, or multiple GPUs using NVIDIA SLI technology, delivers significant performance
improvements in gaming, visual computing, and compute-intensive rich media applications
without costing more money.

GeForce GTX 200 GPUs – Architectural
Improvements
The GeForce GTX 200 GPUs implement a number of key architectural improvements. Not only do
these changes improve performance by 1.5× on average over the prior generation, but also
improve architectural efficiency, measured in performance/square millimeter and
performance/watt.
The GeForce GTX 200 GPUs significantly reduce idle power, hovering around 25 watts, which is
pretty incredible for such powerful GPUs. HybridPower™ is also supported (see HybridPower
section below), so the GPU may be turned off when used in nForce® chipset-based motherboards
that support HybridPower and have integrated motherboard GPUs (such as nForce 780a and 790i
enthusiast motherboards).
The GeForce 8 and GeForce 9 Series implemented the first version of NVIDIA’s unified visual
computing architecture. The new GeForce GTX 200 GPUs implement a second generation of this
architecture. While the foundation of both architectures is a scalar/unified/DirectX 10 processing
core, GeForce GTX 200 GPUs provide many more architectural enhancements than simply a
dramatic increase in the number of functional and processing units.
Here are some of the key advances found in GeForce GTX 200 GPUs versus GeForce 8 and 9
Series architecture GPUs:
‰
Support for three times the number of threads in flight at a given time
‰
New scheduler design for 20% more texturing efficiency
‰
512-bit memory interface
‰
Improved z-cull and compression technology for better performance at high
resolution
‰
Architectural enhancements for geometry shading and stream out performance
‰
Full-speed, raster-operation (ROP) frame buffer blending (vs. half speed on 8800
GTX)
‰
Improved dual issue for more efficient and higher performance computation
‰
Twice the number of registers for longer and more complex shaders
‰
IEEE 754R double precision for improved floating-point computational accuracy
‰
Hardware support for 10-bit color scan out (DisplayPort only)
All of these improvements combined with the large increase in functional units, delivers the next
generation of visual realism and ultra-high-resolution DirectX 10 gaming.
Refer to the Tech Brief titled “NVIDIA GeForce GTX 200 GPU Architectural Overview” for more indepth descriptions of all the new architectural enhancements.
10
Power Management Enhancements
GeForce GTX 200 GPUs include a more dynamic and flexible power management architecture
than past generation NVIDIA GPUs. Four different performance / power modes are employed:
‰
Idle/2D power mode (approx 25 W)
‰
Blu-ray DVD playback mode (approx 35 W)
‰
Full 3D performance mode (varies—worst case TDP 236 W)
‰
HybridPower™ mode (effectively 0 W)
Using a HybridPower-capable nForce motherboard, such as those based on nForce 780a or 790i
chipsets, a GeForce GTX 200 GPU can be fully powered off when not performing intensive
graphics operations and graphics output can be handled by the motherboard GPU (mGPU).
For 3D graphics-intensive applications, the NVIDIA driver can seamlessly switch between the
power modes based on utilization of the GPU. Each of the new GeForce GTX 200 GPUs integrates
utilization monitors (“digital watchdogs”) that constantly check the amount of traffic occurring
inside of the GPU. Based on the level of utilization reported by these monitors, the GPU driver can
dynamically set the appropriate performance mode (i.e., a defined clock and voltage level) that
minimizes the power draw of the graphics card—all fully transparent to the end user.
The GPU also has clock-gating circuitry, which effectively “shuts down” blocks of the GPU which
are not being used at a particular time (where time is measured in milliseconds), further reducing
power during periods of non-peak GPU utilization.
All this enables GeForce GTX 200 graphics cards to deliver idle power that is nearly 1/10th of its
maximum power (approximately 25 W on GeForce GTX 280 GPUs). This dynamic power range
gives you incredible power efficiency across a full range of applications (gaming, video playback,
surfing the web, etc).

GeForce GTX 200 Board Design
The GeForce GTX 200 GPUs are fully encased in a high-tech, sculpted, dual-slot metal enclosure
and they implement dynamically adjustable and quiet fan technology. Board temperatures
typically do not exceed 80°C in an ambient room environment with proper case cooling, allowing
the GPUs to perform at full speed during the most intense 3D gaming efforts, while also keeping
board noise to a minimum.
