Lítið að gera í vinnunni hjá mér og ég ákvað að safna saman smá upplýsingum um nV20, næsta kort frá nVidia.. og þetta hef ég sett saman úr öllu þessu:

nV20, næsta kynslóð af kortum munu fyrst líta dagsins ljós á sýningu í janúar, og koma á almenan markað 27. febrúar

Specs: (og geforce 2 ultra specs í brackets fyrir aftan)
- Core: 300MHz [250 mhz]
- Memory: 250MHz DDR SDRAM (samtals 500 mhz, gæti vafnvel verið meira) [samtals 350 eða 460, ég er ekki alveg viss hvernig ég á að lesa úr þessu :)]
- 256bit memory bus [sama held ég]
- 12.8GB/sec memory bus bandwidth [7,36 gb]
- Fillrate 1.8Gpixel/sec (5.4Gtexel/sec) [1 gpixel sec]
- 6 rendering pipelines með 3 texturing units hver [einhverstaðar sá ég að þetta væru tvöfalt fleiri en á geforce2]
- 0.15 micron kubbur [.18]
- ~$800 retail [$500]


Ég verð nú bara að efast um 800$ verðmiðan á þessu.. og vona! :)

Hérna eru smá quotes:

“NVIDIA will release its NV20 in two months. Taking the advantages of (1) a new architecture of the chip with advanced rendering pipelines and memory-interface, and (2) Hidden Surface Remove (HSR) support, NV20 has great Quake3 performance boost over an overclocked GeForce2”


Og hér:

Pioneer of the first ever GPU (Graphics Processing Unit), Nvidia is now introducing a programmable GPU, seven times faster than the original Geforce 2 Ultra, the NV15.

According to the document, the chip's performance will depend on the application it is running on. In environments where there are low detail scenes (large triangles, simple geometry, hardly any depth) the NV20 is only twice as fast as the previous Geforce 2 Ultra. The difference in performance grows however with the complexity of the 3D scene (multitude of small triangles, very complex geometry, a lot of depth).

The anti-aliasing performance of the chip is also said to have increased substantially. Nvidia gives the NV20 a 300 percent increase in performance compared to the NV15. The performance of the chip doubles when handling geometrical data. According to Nvidia the NV20 is able to handle one trillion operations and 100 gigaflops (floating-point operations) per second.

The performance increase is achieved through better design, according to the documents: the storage interface is a completely revised version compared with the Geforce 2. Downloading large quantities of geometrical data should now flow substantially faster, according to the documents.

In addition, the NV20 is said to have a ramdac speed of over 500MHz as well as an faster clock rate.

There is a new pixel shading experience for 3D-textures and curved surfaces will cater for a 3D visual quality. The NV20's gradual fogging effects and per-pixel bump mapping will primarily enable the presentation of even more realistic characters as well as natural effects. "
