Starting out with the basics, the GT200 core is manufactured using the tried and trusted 65 nanometre process, the same as that used for G92. This does, however, make it ripe for a 55 nanometre die shrink at some unspecified point in the future, just as the 90 nanometre G80 was shrunk into what became the 65 nanometre G92. The GT200 chip makes use of a massive 1.4 billion transistors, eclipsing the 681 million transistors used by G80, and leaving us with a whopping huge GPU die of around 576mm2. As per G80, the size of the GPU itself means that all I/O logic has been moved to a separate chip, meaning that the NVIO chip makes its return with GT200 to handle inter-GPU communication for SLI as well as handling any and all display outputs on the graphics board.
