The architecture is currently code-named Trinity and denotes a combination of Trinity-enabled motherboard (the 590s) and Trinity-enabled graphics cards. Once that combination is set in motion, the available bandwidth for the cards will go from 4GB/s to 5.2 GB/s, essentially – a legal overclock of the PCIe bus, going from x16 to "x20" or "x22", depending on the final stability tests the company conducted recently.
This isn't the first time Nvidia did a bit of spec tweaking, since the first PCIe products, bridged with the famous BR02 chip – worked at a rate which some reps called "AGP 12X".
