Analyst: Nvidia "GeForce5" Could Be Late - Hilbert Hagedoorn @ 15:13

Nvidia Corp.'s next-generation NV30 could miss this year's launch window "for all intents and purposes," a Wall Street analyst said Wednesday. In downgrading the stock of Nvidia, Santa Clara, Calif., Prudential Securities' Hans Mosesmann said he wanted to prepare investors for the "worst-case" scenario, that shipping volumes of the NV30 or "GeForce5" could be pushed out until 2003.


"While Nvidia's execution track record is impeccable and longer term prospects are quite good, we would rather stay on the sidelines until more data points are available regarding the new product launch," Mosesmann wrote.

In an email to ExtremeTech, Mosesmann said that he didn't reduce the company's share price target, but did downgrade the stock to a "Hold". Prudential does trade shares of Nvidia stock, and also assisted in a public offering of Nvidia stock.

"I didn't cut numbers officially, but wanted to set expectations to worst case. My guess is (that) NV30 or NV31 will miss this year for all intents and purposes," Mosesmann wrote. NV31 is considered to be a GeForce4 with an integrated AGP8X interface.
Officials at Nvidia did not return written requests for comment at press time.


x3dfx Community folks claim that delay could be justified due to nVidia's backstep into 0.15mm process from the initial 0.13mm
They also stated that currently nVidia hasn't got any SLI technology like ATi's MAXX so they seriously doubt if nVidia could produce a SLI version of their upcoming chips in order to compete against a possible RadeonMAXX next-gen chip by ATi.

edit: Maybe x3dfx guys are 3dfx loyals but personally I think their claims are a bit right. What's your comments guys?
