There are usually a certain percentage of parts during any manufacturing process that don't perform up to specifications. In the semiconductor industry, many of those parts will end up being speed-binned and set aside for use in less stringent applications.

NVIDIA started mass production of its GF100 GPU using their new Fermi architecture on TSMC's 40nm process in January. Yields weren't great, but they were good enough for NVIDIA to ship their GeForce GTX 480 and 470 graphics cards in April. Their primary competitor, ATI, had been shipping their own DirectX 11 5870 cards for over six months.



Faced with a surplus of chips and a lack of a mainstream performance product, NVIDIA is now launching the GeForce GTX 465 for $279. The primary difference on the graphics card is the use of a 256-bit interface and 1024MB of GDDR5.

However, the card itself uses the same cooling fan and PCB as the rest of the GTX 400 series, which means that NVIDIA's cost still remains very high. The die size of the GF100 chip is massive, measuring 23mm x 23mm for a total of 529 square millimeters. By comparison, theCypress chips used in the Radeon 5800 and 5900 series cards come in at a more moderate 334mm², making the GF100 almost 60% larger.
