NVIDIA documents reveal details about GeForce 7900 GTX such as core speed

We've come across information that confirms NVIDIA's release of its GeForce 7900 GTX, the next flagship for the company. According to NVIDIA documents, the new cards won't be announced until sometime in the beginning of March (the 8th or 9th). The new GPU will be manufactured on 90nm and set to operate at 655MHz. Although this number is still unconfirmed, our sources indicate that this is a final number.

Quick specifications for GeForce 7900 GTX:
  • PCIe native
  • 655MHz core frequency
  • 256-bit memory interface
  • 52GB/sec. memory bandwidth
  • 15B pixels/sec. fill rate
  • 1450M vertices/sec.
  • 24 pixels per cycle
  • Built in twin dual-link DVI support for twin 2560x1600 resolution displays
The documents from NVIDIA also indicate that GeForce 7900 GTX will be "twice as fast as previous generation chipsets" in floating-point performance, but it would be difficult to really consider the 7900 series a next generation component over GeForce 7800. No confirmed board pictures were available at the time of this article but the GeForce 7900 GTX is set to be a dual-slot design. According to the documents, NVIDIA is making sure that the launch of the GeForce 7900 GTX will be a hard launch, indicating that  users can expect products to be available for purchase immediately on the day of the announcement.

NVIDIA does have one trick up its sleeve.  In late March, NVIDIA wil also announce a single slot version of the GeForce 7900 specifically for Quad SLI setups.  Some manufacturers have suggested that Quad SLI may even become available as a discrete solution -- not just Dell's playtoy.
