A few details on NVIDIA's GeForce GTX 480 GPU

Hexus.net grabbed some info from the card's retail packaging:

NVIDIA remains tight-lipped over the card's specifications, but we can confirm from the box that it will have 1,536MB of GDDR5 memory.

The rear outputs will comprise of twin dual-link DVI-I connectors and a mini-HDMI port (v1.3a). No provision for DisplayPort, then?

The power requirements are such that it needs more juice than twin 6-pin plugs can supply, and the setup is the same as a Radeon HD 5970's.

A chunky PSU is recommended, pitching in at 600W - 42A on the 12V line - for a single-GPU system. Add at least 250W for a second card.

And then there's this, from Digitimes.com:

Second-tier graphics card makers are unlikely to start mass shipments of their Nvidia GeForce GTX 480/470-based (Fermi) graphics cards until April despite that Nvidia plans to announce the GPU on March 26 since most of the them have not yet received complete reference board designs, according to sources from graphics card makers.

"The sources expect Nvidia will give supply priority to first-tier makers or makers that only produce Nvidia cards. Listings offering cards from XFX and PNY with GTX 480 models priced at around US$679.99 and GTX 470 at about US$499.99 were briefly available at some online retailers, but have since been taken down. PNY contacted Digitimes to stress that it is not offering pre-orders for Fermi cards at this time, which implies that the listings were the result of miscommunication in the company's channel."

Some market watchers originally expected AMD to drop its graphics card price to counter the launch of Nvidia's new cards, but since the prices of Nvidia cards are higher than AMD's existing cards, watchers now believe any price war between the two chip makers is unlikely to start until after May.
