I actually PURPOSE OF STATEMENT This report will review Voodoo5 5500 with NVIDIAs Geforce2 Extremely to determine which will accelerator provides the best efficiency. Both businesses accelerators reveal the same objective, to bring the very best visual quality conceivable.

Even though both firms share a similar goal, all their approaches are really different. Cost will also be resolved. The following features will be analyzed: Dual 3dfx VSA-100 T-Buffering Fill Charge 32-bit Z-Buffer/Stencil Synchronous dynamic random gain access to memory 32-bit Color II 3D THE IMAGE 3D things are created simply by connecting two-dimensional polygons. Things appear to be THREE DIMENSIONAL dimensional because the computer computes the necessary aspects to give the illusion of depth.

The computer then designates a give texture to each object, textures are the covering up of the target. Like in real life, different textures have different homes, like color, luster, opaque, etc . These types of objects happen to be then viewed on the personal computers monitor. A large number of 3D things can be mixed to create a 3D environment.

A THREE DIMENSIONAL environment may be the computers technology of a produce believe community. When the camera, the point of view inside the 3D globe, moves, the computer calculates the height, width, interesting depth and the light of every thing and adapt them in way that from the point of view of the camera, you appear to be moving in the environment. What is 3D? The first dimensions is a range. The second dimension, a airplane.

This world is explained vertically and horizontally. It’s this that you bring on a document. The third dimension, our sizing, allows free of charge movement and perception with the addition of depth. This allows movement all around, up, straight down, left, right, forwards and back.

All computers come pre-installed with a two-dimensional (2D) images board the hardware that creates the pc screen images for toned applications just like Microsoft Expression and Excel. But , for making 3D images in current (or on-the-fly), a computer must make millions of sophisticated mathematical computations every second. This can produce games and 3D images applications gradual and dried meats as the computer gets involved rendering THREE DIMENSIONAL images in addition to running the program. 3D accelerators fix this problem.

When you install a 3D fender, the 3D IMAGES graphics recently rendered by CPU (your computers processor) are now made by the 3 DIMENSIONAL accelerator. This significantly enhances the performance, enhancements, and substantially improves the 3D encounter. III VOODOO5 5500 The Voodoo5 5500 is 3Dfxs latest THREE DIMENSIONAL accelerator. The card features dual 3dfx VSA-100 chips, Current Full-Scene HW Anti-Aliasing, the exclusive T-Buffer Digital Motion picture Effects engine, Z-Buffer/Stencil, 32-bit Z-Buffer/Stencil, 64MB of graphics memory, 32-bit color.

Dual 3dfx VSA-100 3 DIMENSIONAL objects are broken down in to primitive polygons using triangles. The 3D processor(s) after that use primitive polygons to accomplish calculations (Z-Buffering, FFSAA, and so forth ) The Voodoo5 5500 duel VSA-100 chips are able to process 11 million triangles a second. T-Buffering Basically, T-Buffer technology makes numerous clones of the same scene.

The copies are then combined and end result to the video. This process considerably increased the quality of the images viewed. They appear soft without space artifacts. The majority of 3D greeting cards on the market apply certain form of FSAA but the 3Dfxs T-Buffering offers other essential features just like depth-of-field blur.

The moment humans check out things, the eyes concentrate on the object that we are looking at and never its natural environment. This is why in real life, the only object we are able to truly observe clearly may be the object concentrated on. In current THREE DIMENSIONAL games, nevertheless , there is no interesting depth of field, everything is rendered with perfect clearness regardless of how close our electronic eyes are said to be. Currently a large number of game developers deal with this matter by using a haze effect, so objects which have been farther apart are blurrier.

Yet , this does not appearance real considering that the fog obscures and fades the colors in the distant. With all the T-buffer, depth of discipline is a fact, making made images much more realistic. The T-Buffer offers two additional abilities: gentle shadows and soft reflections. Shadows and reflections in frames that pass through the T-Buffer look more practical.

Voodoo5 5500 uses T-Buffer Digital Cinematic Effects engine smoothes motion and improve photo quality or exaggerate movement for effects. This technology powers the cards most significant attribute, Current Full-Scene Components Anti-Aliasing (FSAA). Full-Scene Anti-Aliasing (FSAA) is definitely the removal of aliasing artifacts. Aliasing artifacts come in two forms: jaggies, or stairstepping of diagonal lines, and pulsating or popping of incredibly thin polygons.

These kinds of spatial artifacts occur since the scene staying rendered is usually under tested. Full-scene anti-aliasing smoothes the jagged lines and eliminates the scintillating of very thin things by taking many samples of the scene and blending these people together. In this way a much softer, far more realistic and desirable image. To ensure this technology to deliver the best image top quality, each image must have 16-30 copies scent through the T-Buffer.

Sadly with the processor on the credit card this is not likely. It requires a lot of times even more fill-rate and geometry and triangle processing power than has become available. 3dfxs current T-buffer uses many fewer goes (somewhere about 4) to hold within an acceptable frame rate. With no full 16-30 passes, yet , discrete pictures of reflections/motion blurs could possibly be observed, rather than smooth changes.

Complete Rate The Voodoo5 5500 has a complete rate of 667MegaTexels. Load rate is definitely the number of texels that can be delivered per second. A texel is the littlest graphical element in a two-dimensional (2-D) feel mapping utilized to wallpaper the rendition of a three-dimensional (3D) object, resulting in the impression of a textured surface. The complete rate is definitely directly relevant to the frame rate or the fps.

To be able to achieve the best 3D encounter, both a top fill rate and a higher frames per second happen to be needed. This kind of report will examine the Voodoo5 5500s frames per second later on. 32-bit Z-Buffer/Stencil Like a number of other 3D credit cards the Voodo5 5500 features 32-bit Z-buffer/stencil. In order to understand Z-Buffering, you first must possess a basic knowledge of Z-Sorting.

In order for the pc to give the illusion the computer must calculate which will objects should certainly appear to be lurking behind other objects. In Z-Sorting the computer systems rendering engine sorts each polygon coming from back to front depending on its theoretical position around the Z-axis. The pc then pulls each thing from tailgate to cab, objects having a closer Z-axis to the camera overlap objects behind them, creating an image of depth. Z-Buffering is a quicker alternative to Z-Sorting.

A depth worth is designated to ever before pixel which enables up the surface area of an thing. Pixels which can be closer to the camera happen to be assigned decrease values although pixels which have been further away from camera are assigned higher values. Before the computer pulls a new pixel, the px depth value is in comparison with the interesting depth values of some other pixels that share similar coordinates (position on the screen). The pxs are only drawn if they have lowest interesting depth value, meaning that they are closer to the camera.

Z-Buffering/stencil ensures that needless pixels, (pixels that would be blocked by a pixel of one more object) aren’t drawn. Synchronous dynamic unique access recollection (SDRAM) The Voodoo5 5500 has 64MB of Synchronous dynamic random access storage (SDRAM) having a clock acceleration of 166MHz. Synchronous MASS (SDRAM) is a generic identity for different kinds of dynamic unique access storage (DRAM) which have been synchronized together with the clock rate that the microprocessor is optimized for. This tends to improve the number of recommendations that the processor chip can perform in a given period 32-bit Color The Voodoo5 5500s dual 3dfx VSA-100 chips support full 32-bit color precision, meaning that can be can display approximately 32 thousands of different colors on your monitor.

The dual VSA-100 potato chips are able to deliver a maximum SECOND rendering potential 2048 pxs by 2048 pixels, displaying amazing details of SECOND images. IV GeForce2 Extremely The GeForce2 Ultra Graphics Processing Unit (GPU) can be NVIDIAs newest 3D fender. The card includes a 250MHz GeForce processor, 64MB of Twice Data Price (DDR) SYNCHRONOUS DYNAMIC RANDOM ACCESS MEMORY running for 230MHz (giving an effective time clock speed of 460MHz). 250MHz GeForce 250MHz GeForce cpu can render 31 , 000, 000 triangles per second.

Fill Level The GeForce2 Ultra contains a fill rate of 2 GigaTexels per second. FSAA GeForce2 Ultra uses FSAA technology. The GeForce2 Ultras usage of FSAA is not packed with a T-Buffer and does not provide depth-of-field blur, soft-shadows or soft reflections. The GeForce2 Ultra truly does include a feature like to Z-Buffer to increase realism, the feature is called convert and lighting (T, L).

How can transform operate? Transform overall performance dictates how precisely computer software developers may tessellate the 3D things they create, how various objects they can put in a scene and exactly how sophisticated the 3D universe itself can be. To tessellate an object methods to divide that into smaller sized geometric things, such as polygons. The images underneath are examples of a sphere tessellated by distinct degrees: All the images previously mentioned represents a similar sphere, however the image for the far correct is plainly the most genuine of the 3. It has been created up into five times as much polygons since the sphere on the much left, and for that reason requires five times the convert performance because the sphere on the left.

That may certainly not seem very important for one sphere, but mainly because hundreds to thousands of items are often displayed in views, without a GRAPHICS those things have to share the limited processing power in the CPU, pushing software programmers to finances processing duties. Now with an NVIDIA GPU transform calculations are offloaded from the CPU, allowing more detailed objects with higher polygon counts to become processed more quickly. With modification a new world scene may have lots of trees and bushesrather than just a single treeand each shrub can incorporate many leaves created by thousands of polygons. Since the GPU relieves the CPU of the burden of determining the changes, you will be able to see scenes abundant with intricate objects that look actual and approach like all their real-life equivalent.

Not only will the objects and heroes be sophisticated, but many even more can can be found. How does lamps work? The human eye is far more sensitive to changes in illumination than it is to changes in colorwhich means that an image with lighting communicates more information to a viewers more efficiently. The discrete lighting engine with an NVIDIA GRAPHICS calculates range vectors via lights to objects and from objects to a audiences eyes within just 3D displays. Lighting calculations are an effective way to add both refined and not-so-subtle changes in brightness to 3D IMAGES objects in a manner that mimics actual lighting circumstances.

32-bit Z-Buffer/Stencil The GeForce2 Ultra uses 32-bit Z-Buffer/Stencil technology. Double Data Rate The GeForce2 Extremely most notable characteristic is their speed. The features 64MB of Dual Data Price SGRAM (DDR). DDR provides for data to be fetched about both the growing and slipping edges with the clock therefore doubling the effective copy rate in the clock, the capability at which the memory will be able to collected by processor.

The 64MB of DDR has a time speed of 233MHZ, although because of its ability to send information on the increasing and slipping edges in the clock promoted has a time clock speed of 466MHz. 32-bit Color 250MHz GeForce processor supports full 32-bit color accuracy. 250MHz GeForce processor has a optimum 2D rendering ability 2048 pixels simply by 2048 px. Analysis The two cards will be powered simply by different technologies and different processor chip sets good results . the same critical goal: to achieve the best 3 DIMENSIONAL experience possible.

The very best 3D experience is as you run by a very high image resolution with a high fill rate and having a large number of fps (over sixty frames per second (fps) is ideal). In order to identify which credit card is superior both are attached to identical pcs. Each credit card runs a similar 3D software while measurements are considered at distinct resolutions. The attached chart compare the two 3d accelerators at several resolutions.

The graphs demonstrate the frames per second at different resolutions. At larger resolutions the GeForce2 Extremely is a more stable performer and provides a more genuine 3d knowledge. VI REALIZATION The GeForce2 Ultra outperforms the Voodoo5 5500 in all respects. VII PRICE Retail price for the two accelerators in Toronto, Canada (in Canadian dollars)is: GeForce2 Ultra: $639.

00 Voodoo5 5500: $450. 00
