Intel pushing for PCI-Express 2.0 x2

Written by Slobodan Simic

Fairly easy and painless, at least for Intel

According to a VR-Zone.com report by our old colleague Lars G. Nilsson, it appears Intel is pushing for PCI-Express x2 interface simply because PCI-Express x1 just doesn't provide enough bandwidth and PCI-Express x4 is just simply too wide and complicates things, chip wise.

Intel appears to be pushing for implementation of PCI-Express x2 due to the fact that current SATA controllers and USB 3.0 controller for that matter really need more bandwidth and are currently limited to PCI-Express x1 or x4 in some cases that sounds like overkill and makes things a bit more complicated for motherboard implementation.

Of course, PCI-SIG, an association that controls PCI-Express standard has no plans for PCI-Express x2 interface support. Of course, we are talking about Intel here and things can easily change.

The other side of the story is that Intel might want to push technology in order to bring its Thunderbolt tech a bit closer to consumers, as it might be that the PCI-Express x2 is a sweet spot for Thunderbolt controllers.

Hang on, hasn't PCIe 3.0 only just started being rolled out, so what's the need for this new interface?

Or they could push for quicker adoption of PCIe 3.0, which improves throughput per lane, or include more PCIe lanes on their processors and chipsets.

Problem solved.

I don't get intel sometimes, They're doing the same thing with USB 3.0, it's only just started getting it's first native support with the AMD Llano southbridge chipset and then intel went and announced Thunderbolt

It will be some time until PCIe 3.0 will be adopted by the add-in board and bridge manufacturers for now PCIe 2.0 is still enough, except for SSD's and future graphics cards.

Well, F x2... use x4 as standard and let the mainboard manufacturers wire them per specs or need. If the chips has 4 x1 or 2 x2 they would be able to pick one way or the other but the size of the port wouldn't change. Otherwise, 3 years later we'll get to see x2 being dropped as well out of the same reasons.

damn babies. Intel wants to replace/add the PCIe 2.0 x1 slots with/to PCIe 2.0 x2 slots. that's all. its not like if boards came with x2 slots, intel and thunderbolt would be the only ones to benefit. we already use x16 video cards in x8 and X4 slots, and x1 soundcards and NICs in x4 slots. i don't see what you're crying about.

Do you read at all? http://www.techspot.com/news/44728-sandy-bridge-e-launching-with-reduced-platform-feature-set.html

Kill yourself, problem solved.

A PCIe 2.0 x2 slot is a new interface? WOW! :|

keyword: PCIe 2.0

Man, you people are stooooooooooooo opid!

HERPA DERPA DERP!



What's the point of releasing new slots of an old PCIe version now that PCIe 3.0 is out? may aswell just use a PCIe 3.0 x1 slot

think about thunderbolt part
