Nice info on Ivy Bridge

am i right in thinking that the ivy bridge cpu's will be having quad channel ddr memory, as opposed to dual channel on current sb's, which in itself should increase performance over current sandybridge cpu's

Quad channel would allow for higher bandwidth in theory - I guess the drawback is that you'd have to use 4 matching sticks of ram for it to work...

No, the Socket 2011 Sandy Bridge-E chips will be quad channel.

Ivy Bridge will use the same Socket 1155 as the current Sandy Bridge chips and be compatible with existing motherboards.
 
BD mobo will not be PCI ex 3?

Basically support for next gen standards?

It looks like to me x79 is what Im waiting for.

Will have all the upgrade paths available, particulalry PCI Ex3.

Current SB with its PCI Ex 2 and 8x 8x lanes, is not appealing.

AMD supported SATA3.0 and USB3.0 before Intel. The AM3+ motherboards also support PCI-E 2.0 16X/16X Crossfire and SLI whereas Sandy Bridge motherboards only do so at 8X/8X.

I suspect Ivy Bridge will support PCI-E 3.0 at 8X/8X.

Taken from here:

"PCIe 2.0 delivers 5 GT/s, but employs an 8b/10b encoding scheme which results in a 20 percent ((10-8)/10) overhead on the raw bit rate. PCIe 3.0 removes the requirement for 8b/10b encoding and instead uses a technique called "scrambling" in which "a known binary polynomial is applied to a data stream in a feedback topology. Because the scrambling polynomial is known, the data can be recovered by running it through a feedback topology using the inverse polynomial"[17] and also uses a 128b/130b ((130-128)/130)encoding scheme, reducing the overhead to approximately 1.5%, as opposed to the 20% overhead of 8b/10b encoding used by PCIe 2.0. PCIe 3.0's 8 GT/s bit rate effectively delivers double PCIe 2.0 bandwidth."

This isnt the exact article I saw, but they reckon that due to less overhead, even PCI EX2 GPU's will see increased performance in a PCI Ex 3 slot.

Would be nice if true.

The AM3+ 790FX,890FX and 990FX motherboards already have twice the PCI-E bandwidth in Crossfire and SLI setups when compared to a P67 or Z68 motherboard. Hence, even with the additional overhead there looks like there will be little difference when compared to a PCI-E 3.0 8X/8X setup.

So what one is better, sorry to sound dumb?

I suspect only Intel could accurately answer that question for you but if I were to take a guess I would say that Ivy Bridge will probably offer similar performance to the quad-core Sandy Bridge-E for much less power usage whilst being slower than hex-core Sandy Bridge-E in highly threaded applications.

Also bear in mind that Sandy Bridge-E is due for release next quarter whilst Ivy Bridge won't be with us until Q2 2012.
 
Yeah it seems that Ivy Bridge will use the same socket but not be compatible with existing motherboards (which seems really dumb, mistakes are gonna happen - why not just add or remove a pin like AMD did in the Socket 939 days?).

because unlike AMD,intel likes to move technology forward & new chips need new mobo's. (pci-e 3..etc).
 
True but 15-month lifespans for two mainstream sockets in a row? Seems ridiculous to me.

If it was like AM3/AM3+ where you could use Ivy Bridge in a current Socket 1155 motherboard but without some of the new features, that'd be fine.

You can be forgiven for this since it's very unusual for Intel to make future processors compatible with existing motherboards however it is the case this time.

So the good news is that your current motherboard will accept an Ivy Bridge CPU when they are released next year, after a BIOS update of course.

A lot of people seem to be confusing Ivy Bridge (22nm, Socket 1155) and Sandy Bridge-E (32nm, Socket 2011); the latter uses a new and physically larger socket and is therefore not compatible with existing boards.

No I'm not confusing the two, I've definitely read somewhere than Ivy Bridge will require a new motherboard despite using the same socket as Sandy Bridge. It's all speculation though so it could easily be wrong, it might just be that you need a BIOS update.

Ah, I see the problem here; some of the budget Sandy Bridge chipsets will not be Ivy Bridge compatible. Intel have explicitly stated that H67, P67 and Z68 will be however.
