An allegedly leaked slide from an Intel presentation detailing its forthcoming 22nm Ivy Bridge LGA1155 processors and chipset has appeared, courtesy of SemiAccurate.

If genuine, the slide confirms that the new range of processors will be PCI-E 3.0 compliant. Like Intel's current LGA1155 CPUs, they will still supply just 16 lanes, but each lane will now offer 1GB/sec of bandwidth in each direction as opposed to the 500MB/sec offered by PCI-E 2.0 lanes.

That sounds good on paper, of course, but it’s not likely to make much difference to your current graphics card’s performance; even top-end cards currently struggle to max out the bandwidth on offer from PCI-E 2.0 slots.

In addition to the PCI-E upgrade, the slide also says the new processors will also include a refresh of the Intel HD graphics core built into the chip. However, it's yet to be seen whether this refresh will take the form of a simple speed bump made possible by the smaller production process or a complete redesign.

The slide also seems to back up a previous leaked presentation which allegedly confirmed native USB 3.0 compatibility from the Panther Point chipset that will accompany the new processors. Surprisingly, it also states that the chipset will still only provide two native SATA 6Gbps ports, rather than upgrading to the full six SATA 6Gbps ports supported by current AMD systems.

Are you looking forward to the next generation of LGA1155 CPUs, or does Sandy Bridge do everything you want? Let us know your thoughts in the forums.
