See here for a not-yet-grown-up version of the GeForce GTX 480 Fermi stripped naked.
Nvidia may still be hanging on tightly to its GeForce GTX 470 and GTX 480 GPUs, it seems that some overseas have managed to get their hands on some Fermi silicon.
Earlier this month, German publication Heise (translated) featured two photographs of a GeForce GTX 480 that clearly showed an A2 stepping stamp. The publication measured the package to be 42mm × 42mm.
More recently Expreview captured images found on Chinese forum NGA showing more detailed die shots of GeForce GTX 480 silicon with A3 stepping. The die measured 23mm x 23mm, or 529 square millimeters.
Stay tuned for Nvidia's big reveal of final silicon at the end of next week on March 26.
