Sul sito HardOCP.com sono state pubblicate alcune informazioni riguardo al nome ufficiale di NV30:

It looks as if NVIDIA is changing gears on us a bit and the retail version of the GeForceFX will now officially be a "GeForceFX 5800 ULTRA". For those of you that have already prepurchased GFFX cards, be assured you will get the card that is "Ultra". It looks as if there are no spec changes; 500/500/128MB.

Of course I am sure we will see the labels on the boxes change. If it is "Ultra", it of course has to be better

La GeForce FX 5800 Ultra, questo quindi il nome ufficiale di NV30, disporrà di 128 MB di memoria DDR II a 500MHZ di clock ed il chip video sarà operante a 500MHZ anch'esso.
