Slides detailing Intel's upcoming "Panther Point" chipset reveal that the next generation of LGA1155 processors will feature PCI-Express 3.0 bus to connect with graphics cards. PCI-Express 3.0 doubles bandwidth over PCI-Express 2.0, and comes with a number of new features and electrical specifications. With Panther Point, Intel put an end to chipsets meant for discrete graphics (such as P67). Here on, all LGA1155 chipsets will support Intel Flexible Display Interface (FDI), although only the Z-series will support overclocking. Among the Z-series, Z77 is the top part supporting a wider range of PCI-Express configurations, Z75 supports discrete graphics with up to 2 graphics cards, while H77 only supports one graphics card, and lacks overclocking features.
Unlike the X79 LGA2011 chipset, Panther Point chipsets don't feature massive 10-port SATA 6 Gb/s storage controllers. Like Cougar Point, it features two SATA 6 Gb/s ports, and four SATA 3 Gb/s. The chipset embeds a USB 3.0 controller, but only 4 out of 14 USB ports are USB 3.0, rest are USB 2.0. Intel's Ivy Bridge will make for the company's 2012 Core Family portfolio, supplying entry-thru-performance segments with processor, while enthusiast segment is care of a different platform.
