NVIDIA GeForce2 Ultra
I. Presentation
NVIDIA reigns since some months on the world of the 3D. We can say since more one year as the chip TNT had trully place this society in front of the scene.
Their solution have always been produce a chip which can process the maximum of informations by lose the less than time which is possible. For that, we could see to appear variants increasingly powerful (TNT2 then TNT2 Ultra, GeForce256 SDR follow by the GeForce256 DDR). Today it's the same thing since NVIDIA sell a new chip, the GeForce2 Ultra derived of the GeForce2 GTS.
But you musn't think that the GeForce2 Ultra is simply an overclocked GeForce2 GTS.
Indeed, NVIDIA's engineers had available news technologys which let ameliorate again the core without even so inscribe him more finely. But the result is there : it work at 250Mhz versus 200Mhz for a GeForce2 GTS.
Of course, this power don't assist without an adequate memory and we can say that things hadn't do halfway since the 64Mo of memory advise are function to 230Mhz with the DDR (Double Data Rate), that which equal at the SDRAM 460Mhz !!!
- GPU inscribed in 0.18µm
- 2nd generation of GeForce équipée du Giga Texel Shading
- T&L hardware
- GPU which function to 250Mhz
- 64Mo DDR SGRAM which function to 230Mhz (equal of SDRAM 460Mhz)
- AGP 2X and 4X
- 1000 Millions of pixels/s and 2000Millions of texels/s
- 4 Pixels with Dual Texturing (therefore 8 texels) by clock cycle.
- Shading Rasterizer (shade of a point)
- FSAA Full Scene Anti Aliasing (already control by the GeForce256)
You can find here a recapitulating table :
| GPU | FillRate (single texturing) | FillRate (multi texturing) | Puissance T&L (polygons/s) | Bandwidth |
|---|---|---|---|---|
| GeForce256 SDR | 480Mpixels/s | 480Mtexels/s | 15 millions | 2.47 Go/s |
| GeForce256 DDR | 480Mpixels/s | 480Mtexels/s | 15 millions | 4.47 Go/s |
| GeForce2 MX | 350Mpixels/s | 700Mtexels/s | 20 millions | 2.47 Go/s |
| GeForce2 GTS | 800Mpixels/s | 1600Mtexels/s | 25 millions | 4.96 Go/s |
| GeForce2 Ultra | 1000Mpixels/s | 2000Mtexels/s | 31 millions | 6.8 Go/s |
Exemple of Per Pixel Shading with a GeForce2 GTS or Ultra (the representation at left don't use so the right yes) :
II. Installation
For tests, I have assemble this card with the ABIT VT6X4 motherboard which bear AGP 4X. In order to normalize the tests, the Detonator3 have been install.
You can compare our results with others NVIDIA's cards.
Finally, it is necessary to indicate that this card is particularly well arm with the thermal dissipation : furthermore the combined radiator/ventilator, we have radiators solidly fix on the memory chip. This must let at anything computer to add this card without problems with the case's temperature.
