Does IVY BRIDGE celeron or pentium support PCIe 3.0?

They do support 3.0 but even if they didn't why would it matter? PCIe is fully backward compatible and if you're buying a CPU that cheap there isn't likely to be anything you're doing that would tax PCIe 2.0 speeds.

It's not the speed I'm concerned with--I'm just testing a unique setup and have been told I need a pcie 3.0 compliant cpu.

Yeah, I saw that the celeron was listed with PCIe 2.0, but then i've read forum posts that say the ark.intel.com listing is wrong, and it really does support it.

According to ark.intel.com, the least expensive CPU with 3.0 support is the Core i5.

Anyone with definitive knowledge?

Thanks

Answers in this thread so far:

Yes
No
It dosent matter you dont need it anyway because i know what you need better than you do.


Conclusive stuff here :p

The only Ivy Bridge chips that have PCIe 3.0 support are the i5 and i7. The i3, Pentium, and Celeron do not.

Because the PCI-E 3.0 Bridge / lanes is on-die of the CPU, I would suspect that only the higher margin Core i5 and Core i7 have the logic enabled.

The actual logic may be present in the Celeron / Pentium / i3 but is probably fused off / disabled because Intel works like that.

What motherboard chipset are you planning on using BTW?

Sorry, yup, the Z77A-G45. I've tracked down a Celeron 1610 I can borrow from a friend, and I'm going to borrow the core i5 from my personal computer.

I was told I needed PCIe 3.0 for this project, but I'm personally not sure I need it. At least with those two temporary CPUs, I should be able to see if it's a requirement.

Thanks for all the input.

It doesn't need to be Ivy bridge. I was just under the assumption that for lga1155, ivy bridge was my only option.

Instead of being elusive how about tell us WHAT you think requires PCIe 3.0?

Possible but I would suspect that if it's absent in all of them, it's probably just not part of the dual core die. i3's are not binned i5's, they're a different chip.
