Secretly: Nvidia NV20
Seven times faster than Geforce 2 Ultra
Performance data of the new Nvidia chip NV20 document the performance before branch of the kalifonischen chip chipschmiede in the diagram market.
23. November 2000
After Nvidia with the Geforce presented the first graphic processor unit (GPU), it is to concern now with the NV20 a programmable GPU, which is faster up to seven times than the bisherhige chip Geforce 2 Ultra.
After ZDNet available confidential firm documents of diagram chip manufacturer Nvidia should be more efficient the NV20 up to seven times, expected for at the beginning of January, than the at present fastest diagram chip Nvidia Geforce 2 Ultra.
Depending upon field of application however the performance varies. With scenes with simple complexity (large three-corner, simple geometry, hardly depth complexity) the NV20 is only twice as fast like the Geforce 2. The performance difference increases, the more complex the 3D-Szenen is (many small triangles, very complex geometry, high depth complexity).
The new Nvidia Grafikchip should be faster up to seven times than the predecessor Geforce 2 Ultra.
The performance of the new diagram chip is to have risen also with the so-called edge smoothing procedure (anti- Aliasing) clearly. Nvidia indicates an increase in output of the NV20 opposite the Geforce 2 Ultra of 300 per cent. A duplication of the performance achieves the new chip with the calculation of geometrical data. According to Nvidia the NV20 over quintillion operations and 100 giga floating-point operations per second per second are to execute to be able.
New architecture
The increase in output achieves Nvidia by an improved Design: Thus the memory interface became completely revised in the comparison to the Geforce 2. The loading of large geometry quantities of data is to now run clearly faster. Besides the NV20 accesses GDR memory with more than 500 megahertz. Also the clock frequency for the diagram chip was increased. From future frequency paste frequenzsteigerungen of the NV20 Nvidia promises itself besides clearly more performance than still with the Geforce 2 Ultra.
Gradual nebula gradations (Layered Fog) ensure
for particularly realistic effects
More realism
Further configuration features like a vollprogramierbaren Vertex instruction set, new pixel Shading procedures for 3D-Texturen and Curved Surfaces in hardware provide according to Nvidia for a never dagewesene representation quality of 3D-Objekten.
The possibility of gradually gradated nebula effects and genuine, reflecting Bump map are to enable the NV20 particularly for the representation of realistic characters as well as natural events.
Result
If in confidential documents prove to be true the specified specifications as well as performance specification, Nvidia of his prominent role in the diagram market might become than fair more. Other companies such as ATI, Matrox or 3Dfx cannot follow the rate of development Nvidias at present.
