In questo articolo non ci occuperemo delle caratteristiche della GPU
NVIDIA GeForce 6600GT che abbiamo ampiamente trattato nella recensione "Schede
video NVIDIA GeForce 6600 e 6600 GT" e alla quale vi rimandiamo per
ulteriori dettagli.

Come possiamo vedere dalla tabella precedente sono state evidenziate,
per le memorie, due frequenze di funzionamento diverse: in effetti XFX
non ha ancora annunciato, per questo modello, il valore di detta
frequenza. La scheda arrivata nei nostri laboratori ha la GPU
funzionante a 500MHz e le memorie ad 1,1GHz (550MHz x 2). Ma XFX
potrebbe commercializzare questa scheda anche con memorie a 1,2GHz
(600MHz x 2).
Sul sito web del produttore viene riportato quanto segue:
Features & Benefits
- Revolutionary Superscalar Architecture
Delivers up to 8x the shading power of previous generation products for
screaming gaming performance.
- CineFX 3.0 Engine
Powers the next generation of cinematic realism. Full support for
Microsoft® DirectX® 9.0 Shader Model 3.0 enables stunning and complex
special effects. Next-generation shader architecture delivers faster and
smoother gameplay.
- On-Chip Video Processor
Delivers unmatched video performance, features, and quality.
- UltraShadow II Technology
Enhances the performance of bleeding-edge games, like id Software’s Doom
III, that feature complex scenes with multiple light sources and objects.
2nd-generation technology delivers more than 4x the shadow processing
power over the previous generation.
- 64-Bit Texture Filtering and Blending
Based on the OpenEXR technology from Industrial Light & Magic, NVIDIA’s
64-bit texture implementation sets new standards for image clarity and
quality through floating point capabilities in shading, filtering,
texturing, and blending.
- Intellisample 3.0 Technology
The industry’s fastest antialiasing delivers ultra-realistic visuals,
with no jagged edges, at lightning-fast speeds. Visual quality is taken
to new heights through a new rotated grid sampling pattern.
- Unified Driver Architecture (UDA)
Part of the NVIDIA Forceware unified software environment (USE). The
NVIDIA UDA guarantees forward and backward compatibility with software
drivers. Simplifies upgrading to a new NVIDIA product because all NVIDIA
products work with the same driver software.
- nView Multi-Display Technology
The nView hardware and software technology combination delivers maximum
flexibility for multi-display options, and provides unprecedented
end-user control of the desktop experience. NVIDIA GPUs are enabled to
support multi-displays, but graphics cards vary. Please verify
multi-display support in the graphics card before purchasing.
- Digital Vibrance Control 3.0
Allows the user to adjust color controls digitally to compensate for the
lighting conditions of their workspace, in order to achieve accurate,
bright colors in all conditions.
- NVIDIA SLI Multi-GPU Ready
Dramatically scales performance by allowing two graphics cards to be run
in parallel. (GeForce 6800 Ultra, 6800 GT, and 6600 GT only)
- PCI Express Support
PCI Express is a new Intel bus architecture that doubles the bandwidth
of the AGP 8X bus, delivering over 4 GB per second in both upstream and
downstream data transfers. Only supported in some NVIDIA GPUs. Please
check product details for bus information.
- Microsoft® DirectX® 9.0 Optimizations and Support
Ensures the best performance and application compatibility for all
DirectX 9 applications.
- High-Speed GDDR3 Memory Interface
Support for the world’s fastest GDDR3 memory delivers fluid frame rates
for even the most advanced games and applications. (GeForce 6800 Ultra,
6800 GT, 6800, and 6600 GT only)
- Full-Speed 32-Bit Color Precision
Delivers increased image quality with no performance compromise.
- Full MPEG Support
Delivers a stunning video experience through encoding and decoding of
analog and digital content.
- Advanced Adaptive De-Interlacing
Smoothes video and DVD playback on progressive displays.
- Video Scaling and Filtering
High-quality scaling and filtering technology improves video playback
quality at any window size, including full-screen HDTV resolutions.
- Integrated TV Encoder
Provides best-of-class TV-out functionality for resolutions up to
1024x768.
- OpenGL® 1.5 Optimizations and Support
Ensures the best performance and application compatibility for all
OpenGL applications.
- Dual 400MHz RAMDACs
Blazing-fast RAMDACs support dual QXGA displays with ultra-high,
ergonomic refresh rates–up to 2048x1536@85Hz.
- Dual DVI Support
Able to drive the industry’s largest and highest resolution flat-panel
displays.
- Microsoft® DirectX® 9.0 Shader Model 3.0 Support
Ensures top-notch compatibility and performance for all DirectX 9
applications, including Shader Model 3.0 titles.
- Integrated HDTV Encoder
Provides world-class HDTV-out functionality up to and including
1920x1080i resolutions.
